[Concept] Guns & Grenades in Vanilla MC: Ray-Casting & Bullet Physics [MC 1.9]

[@dragnoz]

this is how maths should be taught! maybe i would have paid more attention trig or just general math functions if this is what i could have made.

[@tydalforceofficial]

+Dragnoz I know you

[@Nick-tk1mk]

Agree

[@McMakistein]

Holy crap! You are so underrated, man! This blew my mind. :O Thanks for the explanation. :OOOOO

[@gamerguppy]

+McMakistein Ye, underrated... story of my life ;). Glad you like it!

[@arcx1003]

+GamerGuppy Buddy, you NEED to make a one command thing.

[@fruitsalatwithfruit]

+McMakistein you are everywhere :D

[@buffalo632v3]

+McMakistein you should work with GamerGuppy for more awesome creations! :)

[@TheRedEngineer]

You did a really good job! This is amazing!

[@gamerguppy]

+TheRedEngineer Thanks man, liked your elevator a lot too! I love it when functionality & aesthetics come together like that!

[@TheRedEngineer]

GamerGuppy thank you! ^^

[@patriciareed1709]

+GamerGuppy can ou please tell me what program i should use for making 3d modles because im going to make some 3d weapons off my own also great build you should really have more subs then you have got you are one of the best redstone people iv'e seen on youtube

[@patriciareed1709]

+Patricia Reed *you*

[@MClabs15]

This is arguably one of the best command block creations I have seen! :O

[@samasaurus6]

Absolutely amazing. It's awesome that you've been able to recreate such accurate ray casting and collision detection in Minecraft, something I thought would never be possible to the extent shown in your video. Keep up the great work!

[@Darth377Zethlyn]

I've done raycasting and bullet physics in 2d Java game development and in 3d minecraft pocket edition modding, but I am utterly blown away by the care and work you put into this! You seriously used so many alternative methods to work around what the command blocks lack- stunning. Fantastic job!

[@cajbajthewhite4889]

Holy crap all my favorite Minecrafters: Sam, Macstein, Drag, are all here to praise this phenomenal piece of work!

[@Onnowhere]

1.9 Has allowed for more possibilities I never realized at first :o This is incredible. Great job on all that programming!

[@yannicmodritscher4646]

+Onnowhere Actually it was done by many people in 1.8.

[@ItsZender]

+Yannic Mödritscher But not nearly as well as done here.

[@yannicmodritscher4646]

You know WubbiConcepts?

[@buffalo632v3]

GamerGuppy, you deserve way more subscribers than you have now. When I saw Logdotzip's video on your creation I thought you would have at least 100,000. But for all the hard work you put into this, all you have is 750. You deserve WAY more and you have all my sympathy.

[@gamerguppy]

+LoonyToon Gaming I might not have 100k subs, but at least I got you (I hope :P)! I had only 350 subs the day before you commented on my vid so it has almost tripled already.

[@buffalo632v3]

+GamerGuppy Holy crap! You are so welcome! I didn't even realize! ! (Yes I am subscribed :)

[@buffalo632v3]

+GamerGuppy I'm so happy for you and hopefully you can make it to 1,000!

[@joonyou9392]

First time I watched this video (about 5 years ago when it was jusy released) I was still in 6th grade, back then I was really into command blocks and actually wasn't bad at using them and could build a lot of stuff myself and all, but this 1 video really blew my mind at this time and no matter what 6th grade me could never understand the math behind it, I kept coming across the video again and again across the years, it kept coming as if it was meant for me to understand it at some points, I don't remember when was the year it last appeared to me then stopped but I remember that for sure I have yet to be able to understand it.. Till yesterday when I found something very nostalgic to me that reminded me of this that made me wanna check thie video out again.. And finally after 5 years I could finally understand it which makes me feel very proud, gotta hand it to you man, your contraption right there, was a revolutionary point for the whole Minecraft command block community.. It was, and still is very impressive and inspirational, even nowdays this could be replaced with the simple /tp ^1 ^ ^ command, but that still doesn't make it any less impressive and doesn't mean that nowdays ideas and concepts regarding ray casting and such aren't related to your concept cause they surely still are, rewatching this video now gave me inspiration to try and recreate this myself in my single-player Minecraft world with new MC mechanics, not sure if I'd really be able to do it TBH but I'll give it a shot just for the sake of nostalgia and to have some fun, thanks for the memories man, hopefully you'll get back to uploading sometime soon, and if not I hope u have a nice life from now on

[@Astro24train]

Well done Gups, once again you've shown your growth :3 It has been a joy for me and the rest of us to see you expand your knowledge and utilize Minecraft as a tool for greater purposes. Well done my friend, I look forward to learning some more ;)

[@dragnoz]

Your explanation is phenomenal!! mind if i show this to some teachers?

[@gamerguppy]

+Dragnoz Thank you and not at all, go ahead!

[@thunderchronus811]

+GamerGuppy HEY! IT would be GREAT if you add some sounds on the GUNS! :D

[@gamerguppy]

There are plenty of sounds, it's just that one of the latest snapshots changed the sound names. Still had no time to fix this.

[@boombren7867]

This is one of the most amazing creations I have ever seen. Definitely the best ray casting concept/explanation I have ever seen. Keep up the great work.

[@koder]

This system is amazing! It must have taken a lot of commitment, never mind maths knowledge and command-block genius, to create all of that! Well done!

[@gamerguppy]

+koder Thanks for your enthousiasm, it was actually meant to show-off the power of ray-casting and why it is critical for the continuation of innovation of Commandblock contraptions that we, commandblockers, get access to such a command in MC 1.9; e.g. /tp @e ~R which teleports the selected entity R blocks into the direction it is facing. It would be great for tools/sports/weapon contraptions, since it would eliminate 100s of CMBs I used to make this happen. Despite the success on my suggestion on Reddit, Mojang seems to have little interest in it sadly ;). But who knows, maybe MC 2.0...?

[@koder]

GamerGuppy I'd love to help you try and sell this idea to Mojang, because a /tp that teleported in polar (spherical) coordinates would be so useful!

[@J3LK4]

I love how much detail is in the whole thing o.o

[@gamerguppy]

+Jelka I tried!

[@triggeredcheats]

+GamerGuppy Hey look its me ;P

[@gamerguppy]

+bcztheboss Thanks a lot for helping me test/bugfix and getting me some nice footage for this vid!

[@spirit8686]

What an amazing job. I've never seen anything like it! Keep up the good work man.

[@AshnSilvercorp]

man that is complex, but it's really thorough. Probably one person who really went through explaining how raycasts actually work. I hope they become easier with other commands later (such as, an extended searching tag that tells what a player is looking at even past the normal block placing range [that would make hitscan possible in an instant, and could help in calculating direction]). I probably wouldn't use this for a normal project anytime soon, but it's good to know someone has tried to break it down. Hopefully someone can make a command template eventually.

[@CrushedPixel]

Whoa, this is impressive.

[@KibitzandtheCaptain]

Hey Guppy, we made a spotlight video of this for you! Hope you like it and keep up the great work man! (We would link it, but we don't want to look like spammers or something)

[@gamerguppy]

+Kibitz and The Captain I certainly liked it! Very entertaining, yet informative. I still have plenty of unreleased epicness in my saves folder... if only I had the time to make all the vids ;).

[@HeliumHelios]

Hey you did really good making this!!!! (came here by watching logdotzip video). Feedback- I played your concept mini game, and it looked like assault rifle bullets were covering my entire screen (which is bad). Also some other gun accuracy that you could fix (sniper rifles especially). I think this is really great, and actually good enough to sell some codes of yours to other people who makes servers!! Verdict: You is epic, 9.5/10

[@nuropsych1]

Dragnoz sent me. This is good stuff.

[@gamerguppy]

+nuropsych1 So you must be one of the teachers +Dragnoz talked about in his comment. Please master, teach me your ways!

[@MineDaft]

So much awesome in this... I don't even know where to begin. Epic work! :D

[@gamerguppy]

+MineDaft Thanks! You could start by downloading the map and have fun with it!

[@cdfdman]

This is amazing, great job!!!

[@gamerguppy]

+CDFDMAN Thank you!

[@allenshort9817]

Amazing guns and an even more amazing explanation! KZbin command blocking tutorials needs more like this!!!!!!!!!

[@gamerguppy]

+Allen Short Thanks, it's these kind of comments that make my day!

[@MyurrDurr]

"If you are interested in how they work. Them give it a shot" Ayyee I see what you did there!

[@gamerguppy]

I aim to please

[@MyurrDurr]

You have really zero-ed in on your skill here with this creation !

[@chuckchuk14]

By the way, if you'd like to hide the damage bar, you can simply make the carrot on a stick unbreakable when summoning it. I think the texture thing is one of my favorite 1.9 features! It let me do SO much on my server project! I've made kegs, weapons, doors, wall panels, all sorts of things!

[@gamerguppy]

Thanks for the suggestion! But I actually did hide the damage bar before releasing the map, but not before shooting the video. Bit stupid of me :).

[@chuckchuk14]

GamerGuppy Haha, nono, your vid's still awesome! Don't get me wrong! also, isn't there a way to make it so that the texture ONLY appears if the items is unbreakable? As to not have to sacrifice a set of tools? I heard that somewhere but I'm not sure... The only thing I'm really salty about is armor..... They didn't give the same damage value capability to armor...... Salty.

[@fluxs8949]

U heeft mij nu zo geïnspireerd om beter op te letten tijdens wiskunde :D

[@gamerguppy]

+Pixel Pocket Kijk daar doe ik het voor! En je mag wel je zeggen hoor. Zo oud voel ik me nog niet ;).

[@nickrl113]

dear GOD YOU HAVE DONE SOMETHING VERY REVOLUTIONARY. You should publish at least the bullet physics module as a one-block command, so that others can make use of your absolutely beautiful mathematics.

[@doctorenigma]

Dude, you need more subs. I'm telling everyone about you. You are so amazing.

[@isaactorbett]

This is amazing. Thank you for this video.

[@gamerguppy]

+Isaac Torbett I aim to please, quite literally.

[@ZkrytobojcaO.O]

Good Job men! You are really good at this. :)

[@gamerguppy]

+Zkrytobojca O.O Thanks!

[@Ryzasu]

OMG this is insane! I didnt even know such maths could be applied to minecraft!

[@gamerguppy]

+Fabulous Killjoy (Yeah) Glad you like it. It's quite a frequently used concept though and MC uses the Math internally all the time since bows/snowballs/etc. all work based on this same principle. The only thing that makes this special is that I was enable to make it with the very limited tools we have available in MC.

[@bluestingstone1933]

Thank you so much for being a fountain of information. You are the first person I have ever needed to pause the video to comprehend what you just said. Did you say how long it took you and how many cmdblocks you used?

[@qwaccc]

GamerGuppy, How do you make such high quality videos, WITHOUT HAVING 1,000,000...just being reasonable

[@gamerguppy]

People want continuous entertainment. My upload rate is slow, since I've a job and do still study. But I very much appreciate your like the videos, and I'll try to keep the high quality content running.

[@qwaccc]

GamerGuppy i don't care that much about continuous entertainment, just quality entertainment!

[@tdlob1]

Sir, your work is inspiring. This is a lot of really good work.

[@gamerguppy]

+Peter Weyland Thank you, that's what I aim for.

[@tdlob1]

+GamerGuppy if don't mind me asking, what are you going to uni for?

[@ItsZender]

Absolutely genius!

[@_Day_]

Hay.^^ _I came from _*_+Logdotzip._*_ He's got the like, and you totally deserve the fave._ ;D That's absolutely amazing, well done. Even though I don't like shooters, I'll probably try that out.^^ Btw, I was able to completely follow your mathematical explanation. If it comes to "vector" in school, I may be bored. xD Nice explanation, short but effective weapon showcase, a very well structured and well made video. This isn't my first time here and you're (still) doing well, guess I have to subscribe this time. ;D Greetings from Germany.^^ | In case you understand German _(as you're dutch),_ here's the whole text again: || Hay.^^ _Ich kam von _*_+Logdotzip._*_ Er bekam einen 'Like', aber du verdienst den 'Fave.'_ ;D Das war absolut großartig, super gemacht. Auch wenn ich Shooter nicht mag, werde ich das wahrscheinlich ausprobieren.^^ Übrigens, Ich konnte deiner mathematischen Erklärung vollständig folgen. Wenn in der Schule "Vektor" drankommt, werde ich mich wohl langweilen. xD Schöne Erklärung, kurze, aber effektive Waffen-Vorstellung, ein sehr gut strukturiertes und gut gemachtes Video. Das ist nicht das erste mal, dass ich hier bin und du machst das (noch immer) super; ich denke, ich muss dich dieses mal abonnieren. ;D Grüße aus Deutschland.^^

[@gamerguppy]

+_Day_ These are the kind of reactions that make my day! Glad you liked the vid and happy that you subscribed. Hopefully I can live up to the expectations with my future vids, since this contraption sets the bar quite high. And yup I do understand German ; I read and understand it in conversation quite well, but writing/speaking... is a whole different story! Groeten uit Nederland.

[@_Day_]

GamerGuppy I hope so too and (obviously) I'm looking forward to new videos. :D _I'll still write in my best English, because of the other readers though._

[@cyber_robot889]

The Best weapon\gun one-command mod I see!

[@goovn822]

LogDotZip has reviewed this, and man, This is AWESOME!!

[@TV-rm4ov]

This is just amazing Guppy!!! May I record a review about this? I will definitely put your youtube in my description. You deserve subscribes and likes!

[@radicalplayer7215]

Man,guns.. HALO GUNS?!?!?? YOU JUST EARNED A SUB!! IL BE LOOKING FORWARD TO YOUR OTHER COMMANDS!

[@mostroyt1230]

KIDS, THIS IS ONE MORE REASON TO PAY ATTENTION ON THE MATH CLASS... TO CREATE MIND-BLOWING CONTRAPTIONS SUCH AS THIS ONE... JUST....I CANT EVEN.... TIP OF THE HAT FOR YO SIR.

[@hbninja9795]

Best vanilla concept ever

[@TheRagingRedstone]

Wow! This is really impressive! :)

[@mattburton64]

Kudos to you this is very impressive!

[@jellyjerzy6127]

I'm really happy Mojang added this new feature to the 1.9 update, I am a resource pack maker too! And I always wanted a feature to add multiple items without replacing any default items, and it was a MIRACLE! when this update comes!

[@MegaChickenfish]

* lays on the ground * FUUUUUTUUUURE!!! FUUUUTUUUURE!!!

[@flint4713]

Ye good GamerGuppy big mechanism big jobs!This is amazing

[@gamerguppy]

+Два весёлых друга Thank you!

[@flint4713]

+GamerGuppy I believe this is not possible but you stopped my question!With my subscription.

[@maulredstone4083]

HOLY SHIT THIS IS AWESOME!

[@squidmannnredstonemaster875]

arent u making guns too? :D

[@maulredstone4083]

SquidMannn | Redstone Master hehe

[@danhtran4745]

This is awesome and amazing!!! Keep up the great work. Hope the tutorial for the gun coming soon, because I want to make gun in minecraft.

[@gamerguppy]

+Danh Tran I'll do my best! I had to take a break for my study. I will also release a simplified system of this that allows a one-command installation. Just curious, what kind of gun are you looking for? Maybe I can use it as an example for the tutorial vid.

[@danhtran4745]

Thank you for the reply, I love your work and how friendly you are to your fans :)). I want to make a sniper gun just like your, but with faster speed. Because when I was playing the gun you made with my friends, I realized that the speed of the sniper is slow (or maybe my laptop is slow ) so it hard to hit player when you are far away. I' m sorry if my English is bad :(.

[@danhtran4745]

BTW, can I make a video that talk about your guns in my small channel. I just want to show people in my country your amazing creation. Of course that I will credit you and put you channel in the description. I just think that it is nice to have your permission, Thanks so much.

[@gamerguppy]

Ofcourse you can, I'd be honored if you did!

[@danhtran4745]

GamerGuppy Ok, thank you. I will sent tou the link as soon as I am done making the video.

[@willendean5194]

Hey, ima download this map for myself. One thing that would be cool to add (Im no command block genius so please correct me if this is impossible) Is bullets that lower when you use the gun, for an example a scoreboard. And maybe if you find a "loot crate" it could add +50 bullets to the scoreboard. Apart from that, great video! you truly are a genius.

[@georgegramenlof9328]

I was wondering if you could explain how to use the projectileID and hitbyID or what type of command I would want for that, because I could see that being extremely useful.

[@UltimateEx]

This is awesome!! I bet Einstein couldn't do this even if he spent his life trying!!!

[@typo691]

+UltimateEx Actually, he probably could, because you're making the main factor that he can spend his own life, being a genius he was, he could've learned coding easily and made this is some impressive amount of time. If you said a specific amount of time he could do it in, then there probably would've been a problem.

[@UltimateEx]

That one Guy Uh I don't think you understand the concept of sarcasm and using it to make a compliment.

[@CommandCoder]

+UltimateEx he did;)

[@UltimateEx]

CommandCoder ... Dangit

[@angelvega2937]

I like it, and im not bad with maths, but...this explode my mind XD

[@99250sf]

I'm awful with math so I understood nothing. xD

[@gregtechnewhorizons]

99250sf too xD

[@jumpyjibely2555]

Truly amazing!

[@rednephalem9655]

Love this concept, nice description of it as well. Would be fun to see if you could expand this to make a camera guided rocket launcher. (You shoot, your pos is saved, you enter GM 3, your orientation affect the proj vel, you gain view of proj). I even imagine that you have done that already. I released a grid/cell based tower defence map, and it would be awesome to have some turret (formation of armorstand heads) that could rotate so that it points to nearest target. Currently I'm limited to 4 directional turrets. I hope you can learn me something.

[@ZoganCraft]

+GamerGuppy could you make a tutorial on how to make the ShotGun?

[@allenshort9817]

Hey, I was wondering where the RoF is determined. I am making a PvP minigame and I want to buff certain weapon's rate of fire and nerf others. Thanks!

[@uvipl6220]

YOU'RE GENIUS!

[@momentodebruh9983]

this is so amazing!

[@MilkJug12]

on the horde s map whenever I try to shoot it the zombies they dont get hurt unless its an exploder weapon like the rocket launcher and the fuel rod launcher and the grenades do you know how to fix it

[@Ridixsys]

how did you make it so that it detected the different durability of the carrot on a stick when right clicked? Like how do you test for when they right click a damaged carrot on a stick

[@nh0522]

Hey a suggestion is it possible when you are holding out the sniper and crouching for the command block to detect and put a custom textured pumpkin head so it looks like you are scoped in and add slowness?

[@gamerguppy]

+NightHunter909 [AreteGaming] Hey, good idea, but have a look at my friend's, Shane Stone, latest creation. He implemented several of these mechanics on top of this idea.

[@TheNoerdy]

Nice!

[@timmylarren4622]

Is there a way to be able to put this machine in to my survival world? I really want to have it in there.

[@ToughDialga007]

Finally someone made a good gun system

[@spiritsk88]

Hello, GamerGuppy. Just asking, how do you give each player a unique ID that prevents the bullets from hitting themselves? Is there any scoreboard objective whose score represents players IDs?

[@ExtrymGamingLTU]

That is amazing!

[@SamuelLHenry]

Really amazing. Is it possible to have it in one command ?

[@mantisropa]

i think its really good, and ground breaking

[@seanfoster5009]

I used this concept to make lightning staffs... THEY WERE AWESOME

[@AratoSami]

I would like to use this or a modified/ simpler version. Do you use any form of text editing programm?

[@deadly_golem]

how did you detect when someone right clicked with the carrot on a stick?

[@dominator7582]

if I can use this mechanism to map?

[@shanewolf38]

Very nice. :)

[@gamerguppy]

+Shane Stone Thanks Shane, you were a big help to me in testing & bugfixing this monster!

[@shanewolf38]

Lol, no problem, man. This turned out awesome! :)

[@TheLoveMario]

There's a slight oversight... If you add Unbreakable:1b to the NBT tags of the weapons, the durability bar is hidden which makes it look nicer. Hope you include this

[@gamerguppy]

+MarioKart7z Check the download, it is included. I was a bit sloppy when I started recording a week ago. One of my testers pointed it out and I fixed it then ;). Well spotted though!

[@nevertakendown1]

This is amazing. A tutorial for custom guns would be great.

[@screenholder9583]

Apsolutely incredible.I was wondering if spawning fireballs out of arrows and snowballs still works in 1.9 and if it doesnt if its possible to recreate guided fireball?

[@gamerguppy]

+Screen Holder It does, but the direction tag cannot be left empty like I did in the video, "direction:[]". In MC 1.9 it needs to have a value. Replacing it with "direction:[0.0,0.0,0.0]" solves that. Hope that helps you out.

[@screenholder9583]

+GamerGuppy It does help me!That means some of my gun concepts could work in 1.9, but unfortunately there is just too many things that make my map not work in snapshots...

[@Jonathan-gj2jd]

do you mind if I copy the commands into a map I am making? I think you did a good job explaining but considering im not that good with commands in MC anyway i dont really know how to replicate it myself

[@Jonathan-gj2jd]

Could I also skype you

[@polski_anonymous2141]

Can I use these weapons do my map ?

[@Taikeb0]

boom.. mind blown... amzing thing.. speechless..

[@cruls5026]

Great work but shouldn't some of these weapons like the Rocket Launcher damage blocks and or leave craters?

[@gamerguppy]

+Robert Binary Hey Robert, it are creeper explosions. Just turn on the "/gamerule monGriefing true", and you'll see the landscape change.

[@SebSharma]

+GamerGuppy where do I increase the radius the guns work in?does this work in multiplayer?

[@conncon9985]

great work!- is it possible to make this a schematic for mc edit?

[@Pioneer-iv2cv]

Where should I put the weapons mechanics only file??

[@moordegaai]

What is the command or are the commands to give players an ID

[@epicman4046]

i know the Video was realy well explained in some parts but you just said it "obtains the Rotational value," can you please explain how it does currently what i see (i downloaded the world) is it finds the nearest aproximation (1-360,then 0.001-0.512) but how can it find a radius (e.g, Rotation is between 90 and 180) thenfind the 1-360 aprovimation then make it accurate by repeating the aproximation but for 3 digits of decimals? im probaly completely wrong but nice video and please explain.

[@epicman4046]

silly me!

[@michaelposprich4268]

I Never see some Big Thing like this bofore . That's a Master...... ... My words are missing because of this ...

[@austinshiner9219]

can you please do a tutorial on how to add in your own weapons

[@sinu9226]

Hey gamerguppy can you make a video where you make an all direction gun and tell us how it works and with raycasting please.

[@strike_fire6510]

The texture pack isn't working

[@bones8431]

if you set the carrot on a sticks item data to unbreakable you could hide its duability bar while still detecting which weapon is what

[@BlasterGem]

how do you use this after the download?

[@lordoffire1806]

There are no sounds in the resource pack and so the guns have no sounds. How do i fix this?

[@gamerguppy]

+LordOfFire There are sounds, (they are all vanilla MC sounds so no texturepack for that needed). It's just that MC 1.9 latest snapshots changed the names of the sounds. I explained it in the description of this vid too ;).

[@strike_fire6510]

Do you want to work for our server? Like staff? We could really use you!

[@krycegames]

what would be the best way to move this over to a already existing map? I have attempted moving the whole structure over to another world using mc-edit but i cant get it working once im there. I put it on a test world and moved over the scoreboard data from the other but still nothing. I think that when i move it over with mc-edit it makes all the commands that start the machine inactive. I also attempting using the structure blocks and copy it in 4 pieces since the amount structure blocks can copy is small. I copied it on the same world and it worked in some ways but it was messed up.

[@krycegames]

I think if i use mc-edit and copy it in one go it would work but i have no idea how to start it back up correctly so it works. I was able to turn every repeating command block from needing redstone to always active. This restarted the command blocks but it still didnt work (i dont actually know if i got them all going again). Tried putting tags on myself as well.

[@krycegames]

I have seen that there was an earlier version of this. I am not sure if using that would help at all. Lastly i noticed the gun sounds werent working on the actual world. That could be just me

[@DarwinMan]

any suggestion on fixing the following error when I try to connect to a lan game on my own network Internal Exception: io.netty.handler.codec.DecoderException: Java.lang.IndexOutOfBoundsException: readerIndex(34) + length(1) exceeds writerIndex(34): UnpooledHeapByteBuf(ridx: 34, widx: 34, cap:34)
