Im creating a simple Terraria clone and its gone well so far, but ive hit a road block: World Generation. This is something i dont know how to do and i need lots of help. Its gonna be a side scroller, like terraria, not from above if that helps.

Sorry man I don't know how to code but I wish you luck

Let's just say that's a little difficult to figure out.

I dont know, maybe look it up.

Look up procedural generation.

when you finish it give us the ID. please

@RandomGuy Of course I will! :D Miiverse is really the only thing motivating me to make it so far, so feed back makes me happy :)

i just love terraria but i cant help i dont know much. i got this only on the 31 of august so i dont know much.

ill google it.

That's fine, you can only learn if you try! That's kinda of one of the points of this project, I need to learn more about how each command works and how to use them, making algorithms and other stuff. I also need to work on finding better ways to compact and increase performance of programs as well. I am by no means good at coding :P

i think i might have found a solution. i found a block called randomize. i think you can type in randomize world or something. i dont know.

Well here's the thing, I need to be able to understand and be able to completely adjust the world generation system, or else I won't be able to add stuff to the generation or fix something if an error comes up about world generation. And it would be nice to have a unique style of world generation as well. But thanks!

also i need help with showing bg. i thought because you were asking world generation you would know how to show bg.

sorry i dont know basic verry well

I don't have very much experience with loading BG's but I have a file on my 3DS somewhere that would have a BG load test on it. But I don't know the key sadly.

if you go to the thing where you publish things, it should tell you the key if its published.

World generation is hard, depending on how advanced you want to get. If you want a simple terrain where you have only 2 types of terrain, that's pretty simple. But if you want like 30 types of terrains with caves and such, i have bad news...

i have an idea. if you make different terrains and randomize where they get put.

@Random Guy well that defeats the purpose, it's supposed to be random, not hand made. @Autz Honestly I just want like a single plains-like biome with trees and go from there. Very simple.but yet I don't know how to even do that.

oh. maybe you can make it generate different worlds randomly but with specific bioms.

also im trying the same now. thanks for the inspiration. it might be a sequel to yours or maybe a prequel.

@Random Guy boi I don't even know how to make one biome :Y

@Random Guy Np! Looks good as well!

mabe you can use the map editor. i have 9 posts left so please dont ask alot anymore today.

heres plantera

progress is progressing.

I think the general idea is to create rules which allow or deny certain aspects to be created. Meaning you will need variables to use as ID's for each specific element. (A tree, a block of dirt, grass, ect.) So, you will use RND, but then you need to use your rules to determine what can/will be placed next to it. On a grid that will be either 4 sides, or 8 including adjacent tiles.

That is only the very basics though, on a larger scale you likely need algorithms for larger sections. These rules will define things like: If there is a body of water, no land will be generated on top, or things like defining mountains.

Sorry, what I meant was for larger sections.. a better example would be biomes. Determining the rules for adjacent blocks is fairly simple, but determining rules for large sections of blocks will be much more complicated and I can't think how you would do it without algorithms that can average areas.

Hopefully that makes sense to you, and take my advice with a grain of salt. I've never actually studied procedural gen, that's just my presumption of how it works in general.

Yeah yeah that was kinda the area I was going for, IDs and stuff.

found something out and tested it too! google ¨code to show bg.¨ one of the results should be smilebasic lesson 34 bg or something like that. click it then scrool down until you see bgput. it will give you directions from there.

repeat the bgput code until your satisfied for random generation! (you might want different numbers in () )

There's no way it's only 2 lines of code 0-0 but k I'll try

So I tried it and yeah! It works, but I'll have to add a couple of things, like rules so it's not so all over the place and looks more like terrain and tree generation!

you can make more of it to make more blocks.

my first game is working! not finished yet though.

Instead of PRINT you can use ?

even further! at the actual game now!

duh! for side scrolling you zoom it in, then if you move enough to the side it scrools!

how do you make rules.

Sadly that's where I stand in this as well, but I think you couldn't use RND like we are right now, we would need a controlled RND, like a RND under certain conditions and based on the conditions it would randomly generate under those circumstances. And to do that there would have to be lots of math and loops.

...That's what I said.

i think they should have made it so that 0,0 coordinates are the bottom left corner of the screen. then we could control it better, because we could give it a limit so it isn't a mess everywhere, its just a really weird ground. if only... (-_-)

Well you can add a layering system like I did where it generates from the bottom up layer but layer until it gets to its max layer by using a FOR loop. With the layering system you'll be able to somewhat control it?? I'm still working it out.

Im very confused about wat anyone here is saying.

That's ok you don't need to understand, we are just being confused on world generation

btw, warrior, im making a btd like game. you can help me if you want. just click my face and find the discussion, you can help if you want.

found something big for sidescrooling! if you have bg zoomed in theres a code called bgmove! you can make it so you can move the bg! ill make a demo to show you!

sorry, the code for moving bg is bgofs.

I am aware of that. I'm working on After War for a bit until my poll on SBS gets off the home page.

k

THIS IS A BIG IDEA! maybe you can place bg with bgput, limiting it depending on the bg thing, then place bg for background over it on the same layer, and not put collision for the background bg!
