Making a Multiplayer Steam Game in 3 Months!

Download Core for FREE at bit.ly/CorexBarji Check out the Core Invitational (submit your application by August 1st): invitational.coregames.com/ edit: (A few of you have contacted me about an IP address showing in the video, I really appreciate the concern! It’s actually the IP of a discontinued vps so there’s nothing to worry about.) edit2: yes, it's an m.2 solid-state drive. But that doesn't quite roll off the tongue as well as "hard drive".

Hey its ok I figured out some other code by using Google lol its OK thanks for putting me in the vid I guess at 0:50 oh and I've been using core since January I've been working on that competition I guess I'm competing against you to win that tesla it also sounds like a good deal so far I've really enjoyed your channel the past few months one thing I don't get is that you don't have a lot of subscribers you deserve waaayyyyy more

I swear, If you make this game super smooth and fast movement this would be a game I would die for. Parkour games are amazing. I am so happy to see you work on this, especially when I see how good you are at programming plus how much it looks like you are enjoying it. Wow. Amazing job! Keep this up! This is bloody gorgeous!

[@vibnnn9117]

Looks great! Exited to start speedruning this too!

[@Oscar_Armstrong]

Maybe consider increasing the player's FOV based on their movement speed when they enter into the "fast" state? This should give a smoother feeling to the sudden appearance of speed lines

[@MMT--Games]

this is my first time seeing Barji, im 2 minutes in and that was enough to make me subscribe. good work

[@Skeffles]

Really well done with this one. Looks like you did a heck of a lot of work and I hope the speed runners enjoy it.

[@Coolness7423]

5:45 Oh, you dont know what karlson is. Its just a game the youtuber Dani has been working on and is currently 17th most wishlisted game on steam, so hit wishlist now gamers *I had to*

[@musicbymason]

Found you from Dani, keep up the great work! Can't wait to play the final game!

[@TylerGreen]

This is really awesome! Your colors are fantastic too. Taking some tips for my games :)

[@floyd5949]

Such quality content! Glad to have found your channel. And man, that dot product took me straight back to them college days

[@DrowsyFoxDev]

That was awesome, can’t wait for part two! 😮

[@gabrielgullidge2701]

Just to clarify, the dot product of two vectors is a1*a2 + b1*b2 where vector a = (a1,a2) and vector b = (b1,b2) and the rule in the video is an application of this rule. cos(x) = (|a| • |b|)/(a•b) (also note that |a| is sqrt(a1^2+a2^2))

[@pejv7903]

you lost me half way into the sentence

[@PrivatePug]

@@pejv7903 a1 and a2 are just the coordinates in that plane where the tip of vector a is. |v| (assuming v is some vector) is the magnitude of a vector which is simply put, the distance between where it begins and where it ends. The whole sqrt(a1^2 + a2^2) is actually just the Pythagorean Theorem (Pythagoras Theorem, distance formula, or whatever you want to call it). The reason this works is because the x and y coordinates when represented as two lines that meet at one end create the opposite and adjacent sides of a right triangle. If you draw another line that connects the tips of the lines that aren’t touching you now have the hypotenuse of the right triangle. In this case a1 is the x value, a2 is the y value, and |a| is the line drawn to connect the tips (the hypotenuse). Assuming you understand Pythagoras Theorem, a^2 + b^2 = c^2, you can plug in a to be a1, b to be a2, and c to be |a|, which will be |a| = a1^2 + a2^2. Simplifying that you get that |a| is just sqrt(a1^2 +a2^2). The derivation of the cos(x) thing is a bit heftier so I’ll leave it in the next comment.

[@PrivatePug]

Let’s define * as multiplication, |v| as the magnitude of vector v, and ‘ as the dot product (my keyboard is a bit limited). If we definite a and b as two vectors, then (a-b) is the vector that connects the endpoints of a and b which creates a triangle. Now that we have defined those vectors we have a triangle with sides |a|, |b|, and |a-b|. We can now use the law of cosines to realized that |a-b|^2 = |a|^2 + |b|^2 -2*|a|*|b|*cos(x). Assume that x is the angle between the vectors a and b. We also I know that |a-b|^2 = (a-b)’(a-b). I don’t feel like also proving this, so just take it as a postulate. If you set both of our equations for |a-b|^2 equal to each other you will with some algebra get that (a’b)/(|a|*|b|) = cos(x). Hope that helped! If not check up some KZbin videos, explaining this stuff in youtube comments does not work well.

[@joba2888]

The editing is so clean! Great video :)

[@djolex15]

Very nice video i saw you in Danis video and looked up for your channel hahah. Nice!

Honestly, your channel is very underrated, keep up the good work :D

[@that_kaii]

First time watching your videos. I can absolutely say these are really fun!

[@unitysparticlesystem]

Favorite games : Grapple , Karlson , Will you snail? , Punch a Bunch , Hyperbolica , Ultrakill... They have particles so I like them

[@ggman.]

Glad you used up in my jam, its a great song

[@theothetorch8016]

I hope you can read this: I think this game would greatly benefit from having a shader similar to what dani used in his 3D among us game. Your game already looks cartoony, and I think that simplicity could look soo cool! If you do experiment with this, than no matter if you will end up using it or not, you can at least get some interesting screenshots from this which is cool for marketing. So I don't see a reason not to try it out. I hope you can finish this, the project looks cool!

[@barj]

Cool idea! If you're in the discord I'll have a play around and share some screenshots :)

[@evilplayz7780]

[@TindallB-Gamedev]

Looks cool so far!

one of the best pvp experiences ive had with a grapple game is Roark's Attack on Titan Fan Game i really recommend taking inspiration its really smooth gameplay and unqiue

Thank you :) *flashbangs*

For the wall running i would use ray casting and then disabling the gravity when the ray is collided so yea… anyways great game love to see it

you should add a feature that would let players make levels

I don’t want to overwork you, but maybe add a map creator? I like those.

Adding a hub world would probably be a pain in the ass, but I feel like in this kind of game it could be super charming

Cool video man! So bad you basically needed to redo your own game from scratch :c But hoping best for the game! 😉

That water level you showed was actually from Mario Galaxy 2. I dunno if that technique was used in Galaxy 1.

[@berkcan3475]

you shouldnt prevent wallrunning same side, maybe he grappled onto something and returned to the wall? To prevent wall climb you can either give higher perpendicular force to prevent coming back with just air movement or put time-based ban for same wall

[@lennium8323]

Yo this looks fun

[@high_dice]

Ooooooh, a gamemode where everyone has to go and hunt a grappler down like they're a dog. That could be fun :)

[@timothymakesgames]

this is pogging

[@thebabigoon]

i think you should redesign your grapple or remove your gun(cause not relevant with forest) or maybe change the place?

[@debadittyamukherjee4339]

Hi I love your videos. Recently I've tried to learn some networking can you put out a walkthrough of how you networked your game?

[@cjgstudio]

bro reminds me of when i made pixel arcade, its like a vr platformer you grab onto shit.. recently made a grapple in VR to work with pixelarcade.. youve done an awesome job here looks awesome on pc!

oh yes

[@Flux23333]

when are you going to add the xtra levels???

[@woosix7735]

You forgot to mention the best thing about the dot product! which is that if you have two vectors, u and v, the dot product u ⋅ v = xu * xv + yu * yv, or in other words, it's super cheap to compute with cordinates

*yes*
