My 2D Sandbox game( Java and LibGDX )

[@emmetcasey6405]

This looks very immersive especially the magic how it lights up Well done keep up the good work

[@rojodo7176]

watched all of your videos and they have always amazed me. keep uploadin; this game is too good to not watch. big fan of the work youve put into this and i respect the graphics and concepts of this game. now; one question: terraria and starbound both have their differences from each other. Now what will your difference be from those two?

[@Edvinas01]

Really nice work on the game so far! I wanted to ask a few questions. I'm working on a similar tile based game (using box2d for physics and Tiled to render the tiles) and I'm curious how did you deal with tile ghost vertices (objects getting stuck between tile gaps) or are you generating a huge mesh for the whole world? Also what data structure are you using to store the tiles (I'm wondering how to efficiently render huge worlds like in Terraria)?

[@hexa3688]

You should create your own tiled map system (this is not really hard to do), and, more important, your own physics code (even easier to do when you don't have to deal with rotations, just with simple boxes). Box2D is not a good idea if you're not using "realistic" physics in your game, like Angry Birds do for example. My map is a big 2D byte array, so I haven't to work with chunks, I can load all the map directly without taking too much RAM.

[@Edvinas01]

I am currently working on my own tiled system, but totally skipped the idea of using simple byte arrays. I'll definitely try that next! As for the physics I kinda have to use Box2D due to the fact that I want accurate and fast physics to be a core part of my game, the only problem so far was ghost vertices between tile connections (also not experienced in writing a physics engine). Though, I'm still curious do you store each tile as a separate physics object (every tile has a rectangle collision mesh). Or do you join groups of tiles into bigger collision meshes. Thanks for the reply!

[@hexa3688]

I just test collisions by looking at ≈30 points of the bounding box around the player (with an "hitbox" class made especially for it), and i look what kind of tile is at the position of each points. So i still only need my big array of bytes, no heavy collision meshes etc.

[@disen135]

hello, looks really great!! how you did that 'fog of war' shading effect ?

[@TRiToNDREyJA]

i was wondering how to generate structures efficiently in my game, would it be possible for you too just give a slight pseudocode walthrough on a base structure generation or something? Just having a hard time wrapping my head around a good system for this.

[@Dizzy-xc7ev]

Hello Hexa. How long did it take you to get to this level of programming skill? Would you say this was hard to do? I recently picked up Java programming after programming in PHP for 2 years, and could use some motivation--seeing this was great motivation. Could you explain the steps you've taken to get to this level?

[@Xpost2000]

+Dublin'sRoses'75 I may not be who your looking for but chill... It's really not as bad as it seems, sure the code might look scary to read but really it's not that bad and tough, when you program I don't think it's about skill really, and it's not about how much you know it's about how you think of ways to do something with what you know. Plus you know PHP? Well that's helpful infact you probably got java already at this point.

[@synthesisgames]

Very impressive!! I can see a lot of work has gone into this. Would you be willing to share source or maybe an example of the procedural/destructible terrain code? I've been researching this myself and you pull it off flawlessly. Maybe could you tell me how you go about it in your game? It's very smooth.

[@hexabeast2098]

Sorry, I don't want to share the source for some reasons, but if you want some help contact me on skype (hexabeast) or mail me (adress in the description of the video)

[@Artyomann]

It's made with tilemaps. Wait, 8 years ago?

[@Mrwiseguy101690]

I have 3 years Java experience but I know very very little about LibGDX. Is there anything I should know before diving into it? Any tips?

[@kyper7552]

Dive in :) i just started myself about a year ago and its been great fun. One piece of advice is to make always program with garbage collection in mind. So if you plan on having a game that generates loads of objects make sure that those objects are in an Object Pool so that the garbage collector doesnt slow down your games.

[@Dodotheuser]

hello , how did you do the generated part , that sounds really hard...

[@hexa3688]

Dorin Doryn Perlin Noise

[@ochigalland6456]

This game is amazing, really. I was just wondering if java + libgdx was a good choice for my game(i have something like this in mind), but now that i've seen this I'm sure it'll do the work Thanks!

[@hexa3688]

Yes, libgdx is really nice :)

[@oiLynXTaZeQo]

Ochi Galland I've just bought a lesson for libgdx on udemy. Hopefully really good :)

[@AgentM124]

"Game: Terraria" I hope you don't get copyright issues for that, although it is just something alike.

[@yiz9374]

btw u should make the pickaxe swing animation wider? like not just a slight up and down but a big swing

[@TRiToNDREyJA]

This is looking awesome! How long ago did you start this? You made the smart choice in using libraries ahaha on my project jm too deep in to rewrite the foundation using libraries.

[@hexa3688]

I'm on it since 6 months I think. I already watched a video of your project, it doesn't look bad too :)

[@marcinkolek252]

Awesome, I like the magic wands and lights most.

[@hexabeast2098]

Thanks

[@yiz9374]

i have a feeling this is what terraria other world is going to look like but higher quality (not saying urs isnt good its amazing)

[@quincysoeliman728]

Holy crap, this looks great!

[@rj-nj3uk]

Was this game created by Yorai Omer and Chris Bednarz or it is a fan made type.

[@hexa3688]

red cat fan made lol, I did it

[@rj-nj3uk]

Nice Game. Much better than minecraft. How much time it took you to make it

[@JuniorjmsPE]

So nice. It looks better than others I have seen.

[@Maetschll]

Amazing project !

[@KlausPfeiffer]

Good work! I loved playing Terraria. What will be the difference to Terraria and Starbound in your game? What's your killer feature? ;-)

[@Sketchosaure]

Oh yeah ! Awesome work !

[@hexa3688]

Thanks :)

[@alexanderandrukov9903]

U are use box2d for phiscs?

[@ToJak91]

How much time does it take to make something like this? I really want to make a game.. But i hate true game engines.. :/ How fast is it to pick up something like LibGDX for Java?

[@hexa3688]

I began to use LibGDX only a few months before uploading this video of the game.

[@Cooltrain]

+Hexa beast How much java did you know before starting to use it. Ive been learning java for about 3 months and am looking into getting into this.

[@hexa3688]

It's not really possible to say "you need to learn x months to be ready", because if what you call "learning" is 4 hours of intense programming a day, it's not the same thing as if you just learn by "reading things about Java a few minutes every sunday when you're not too tired". And even knowing the way you are learning, some people are a lot faster for understanding how things work than others.

[@CarlosBernardo3600]

How did the exchange of arms? Did you join several animations?

[@citizengoose1342]

Very impressive. Is this still a thing?

[@yohannlogFR]

I have a problem with the loading bar that does not go all the way when i start your .jar

[@yohannlogFR]

It's a problem with what? Java? Computer ?

[@adelaide7822]

Tip: use the useless magic things as weapons against enemies and bosses, they are kind off cool, you know!

[@julesklakosz6500]

How had you generated the random map?

[@hexa3688]

Using Perlin Noise.

[@Andrew11415]

Nice work, dude!

[@Hwioo]

Amazing... How did you implement your own physics?

[@oliverb.8995]

programming

[@leedalli7839]

don't try to compare it to Terraria or Starbound. This game is amazing and it has so much potential. Good job dude. Ps Can I do a let's play of this game and what is it called?

[@beanmchocolate3900]

What happened to the trees? I don't have any in my world.

[@SinhtUpthereal]

pretty much inspired by starbound :) nicework

[@Soparinho]

Particle effects looks amazing, do you share them?

[@Flowey_the_Goober]

this looks like a mixture of Terraria Stardew valley and Minecraft it kinda really is 2D Minecraft

[@insertcoin8278]

Damn this game looks great!

[@karlmin8471]

Is this project still alive?

[@st1nger13]

Hey, man, what's with your project now? :)

[@valentinorubio703]

Dude this Is fucking great i love it... Hope you don't get any copyright issues with it.

[@alexanderandrukov9903]

Tell me about best way to study libGDX?

[@dennozz12]

youtube tutorials for understanding the basics, then you should experiment yourself with all the libGDX classes and methods

[@togmeister8604]

Awesome keep up the good work.

[@hexabeast2098]

Thanks

[@sherif573]

did u use tiled map or box2d? awesome game

[@cloownix]

No I didn't

[@sherif573]

which map editor ? and replacement for box2D pls i nee to know from your experience

[@cloownix]

sherif573 No map editor (the map is randomly generated), I did the map class myself. I also did the physics myself.

[@sherif573]

great job congratulations + respect

[@theGreatDpunisher]

+hexa woaw thats a lot of coding.....

[@julz_productions-3755]

You should make monsters or creatures to fight with those "useless magic things

[@empix_]

congratulations! nice

[@user-fe1ke6qe7f]

can i play this game some where?

[@MultiDevan13]

dude thats awesome !!!

[@hexa3688]

Thanks

[@jakeiteasy1]

for real i would play an early access for this game

[@qwerty-jl5zo]

Good job man)

[@AronBike]

download?

[@dukepunzalan6995]

Good Job you're so awesome :) I envy you. Can you give the reference of from where you have learned?

[@Light-tf3jf]

Pls do an update for survival , mobs and multiplayer and crafting ! that game is so AWESOME!!!!

[@hexabeast2098]

Thanks, but the game isn't finished at all yet :(

[@MarcS152]

Good work :-)

[@uemersonpinheirojunior1267]

Good game, nice man!!!

[@CarlosBernardo3600]

Very good :3

[@Supervisor360]

Bro thats epik

[@jesajahjulfors3116]

that..... was........ Amazing!!!!!

[@sherif573]

hello any tutorials?

[@lorincotto863]

Good job :D

[@parisdouady6598]

Wow, impressive.

[@wiktorkalinowski9148]

Great!

[@nika_251]

this isnt half bad!

[@MasterBroNetwork]

Java isn't too good for 3D but it's decent for 2D! :)

[@kyper7552]

its actually pretty efficient now a days with lwjgl backends and what not. The only problem with a lot of games made with java is that they dont handle the garbage collector efficiently and this causes their games to "lag" or feel slow.

[@MasterBroNetwork]

Kyper True but Java on it's own ain't the best. Edit: I take all of this back. (2023)

[@rashid_hafez1]

source code pls

[@moovy2564]

great game! But,...this is not an original products because of it gameplay,ghrapics...its to..same alike like terraria..i know its meant to be that way...try adding some original things that only this game have.

[@purpleice2343]

+Moovy The purpose of this game is to learn how something works by trying to reproduce the same thing other games have... Not to make a game you would want to play.

[@giorgigamer1340]

download links plisssssss

[@daemon4683]

Honestly, I prefer the look of this over Terraria. I hate Terraria.

[@invalid5777]

c++ is wayyyy better rewrite the code in c++ to make it faster

[@sanswich3236]

Why can't people stop stealing craffics and items from terraraia

[@funkypantaloons]

damn craffics

[@MisterIdleYT]

Terraria Like

[@thithuhienthai1946]

Hay

[@hedge6607]

youtube thinks it terraria lol

[@Suzzy_Is_Dead]

u dont know how to use 0:24

[@elpelotudoe]

hello hablo español

[@ps4montages667]

hello i am a voxel designer, i have been doing some jobs designing scenes. If you are interested just email me

[@EvilStryfe25WasHere]

Terraria rip off by javascript

[@JohnWilliams-nv6fw]

Why does every amateur game look like an amateur game? It's always a simple simple side scroller that looks like it was made in 1985.

[@hexa3688]

+John Williams Because it's harder to make a 3D RPG with next-gen graphics without any budget....

[@JohnWilliams-nv6fw]

That's the sad thing then. Most LibGDX games aren't even at the same level as a lot of late 1980s games. It's kind of sad. The only people downloading those games are enthusiasts that are interested in making a crappy game themselves.

[@timcrouch2415]

+John Williams Actually, this game is obviously inspired by Terraria, an "amateur looking game" that made millions of dollars.

[@inactiveaccount7856]

+Tim Crouch I like it do you?

[@sam_music555]

+John Williams 1st depends by which meaning u get to "amateur" and 2nd Do exist some nice indie games that looks like AAA games, and 3rd try u to do a AAA game amateurly ;) sorry for shit english
