AutoTiles OpenSimplex Noise Procedural Generation Godot 3.1 Tutorial

[@sriram97]

This is the best procedural generated map tutorial that i have found so far.

[@maggot9779]

If anyone else is having trouble with the background tilemap not placing stone walls correctly, you have to make sure the subtile size is set to 48 for y.

[@kshitijbaria5883]

GOD LIKE Awesome vid man i was cracking my brains at how to get the auto tiling in a procedural map Didn't know it was this easy Keep it up!

[@MrSmith_]

13:52 Idk if someone else has answered or if you already know by now since this video is 2 years old, but you're exactly right in that it's the frequency per tiles. The denominator value is the ceiling and the numerator is the frequency. Example, 1 out of 4 tiles will be chosen.

[@gingerageousgames613]

Thanks. I always appreciate a helpful comment even if I was fairly certain I was right.

[@nuvod4770]

14:33 Actually, `and` is short-circuit: if left operand is false - right will not be calculated, so you can do comparison on one line

[@ryanbuizon58]

This tutorial is literally the best. The Simplex noise would look great for spawning something like islands!

[@gingerageousgames613]

Thanks. It is nice comments like this that make me think I really need to make some more videos since my short break kind of turned into a year.

[@knightfury7120]

This tutorial was amazing🖤

[@robertoaguiar6230]

Thanks, mate, I'll try it tomorrow in godot 3.2 if I make it I'll let you know

[@tofudeliverygt86]

Exactly what I was looking for, thanks!

[@vishu6787]

I have never seen such use of tile map, looking forward to see new things on this channel, I am trying to come up with a 3d terrain generation for my car game which use perlin noise I'll be great if you can help me go forward.

[@sirbranson5254]

hey im also trying to go the same thing for my 3d fantasy game, have you made much progress? can you share?

[@CoderJK]

This is just what I was looking for! The command to update the bit mask was the missing piece for me! I guess I have no excuse but to make something incredible now. 😊

[@archiebaldry]

great tutorial, man. good job.

[@NeZversSounds]

Procedural proceduralization.

[@judelingan5863]

This tutorial is amazing!

[@Syeno]

So i understand how to make auto tiles for edges and all that, but is there a way to make auto tiling mountains walls? Making mountains is so tedious with this texture pack. A clever work around would save me so much time.

[@gingerageousgames613]

Are you talking about the stone walls that go down in the holes? I actually did auto tile them. Use 3x3 minimal. Then I only used the middle 3 bits to see if it had neighbors to the left or right.

[@jaymhlurbaloyi7813]

@@gingerageousgames613 bro can you post it on GitHub Or paste just that part as a comment I can't figure it out.

[@masterroyale0376]

Great Work! :D

[@ebregains]

I think it would be better if you nest all three functions on a two dimensional loop with the noise value and pass it as an argument. You will avoid iterating through the tilemap 3 times and obtaining that noise value 3 times too. Something like: func _ready(): # ... var noise_value for x in map_size.x: for y in map_size.y: noise_value = noise.get_noise_2d(x,y) check_for_grass(x, y, noise_value) check_for_road(x, y, noise_value) check_for_enviroment(x, y, noise_value) make_background() #... You can even nest this on a new function called generate_world() and just call it in the _ready() function. Anyway, I completely understand that this is an educational video and what I prouposed is maybe harder to read and understand. Thanks for sharing this tutorial, it was really clear!

[@gingerageousgames613]

I agree. But I also appreciate well thought out and clear suggestions. It would be silly for people to think I really knew what I was doing. I have learned a lot from comments like this.

[@robertoaguiar6230]

Hey, man, I'm looping this error and nothing happens. "ERROR: tile_get_tile_mode: Condition "!tile_map.has(p_id)" is true. Returned: SINGLE_TILE At: scene/resources/tile_set.cpp:480"

[@gingerageousgames613]

So what he error is saying is it can not find the tile_id that you are trying to set. So making a fair amount of assumptions on my part I would guess that on line 47 you have set the environment to a number that doesn't exist in your tileset. Check that tileset and make sure you have 4 single tiles or your random num reflects how many tile types you have. Also if you went back and deleted any tiles in the tileset it can make gaps. To check if this is right. Use a number you know is in the tilemap instead the randi num in line 47 to set the cell. That is my first guess.

[@Garfield91076]

Thanks for all the help in your tuts! I just have one question for some reason my tiles are getting lines between them when they are rendered. I have to zoom way out to not see these weird lines. Know anyway to fix that? I could provide a picture of it if that would help.

[@gingerageousgames613]

Are the lines spaces or sprite? If they are spaces check you tile size. If they are part of a sprite check you texture region. Otherwise you could try pixel snap.

[@Garfield91076]

@@gingerageousgames613 Hey thanks for the quick reply! Turns out the lines were just appearing in the editor because I was zoomed in or out and it would make the tiles look blurry and put some weird artifact looking lines in between each tile. Then in the game when I would run it my window settings were weird i guess and messed around with those to fix it. It was creating different a kind of artifacting there. Also like another guy mentioned I'd super appreciate getting the source code if youre ok with giving that out. Having fun with godot but seems like a lot of people dont offer links to their code in tutorial videos. Thanks again

[@gingerageousgames613]

how could you make the environment decorations spawn in the same place when you use the same seed

[@hector_dgz94]

great video, thanks a lot

[@MarkJrLuat]

How do you make a like a small patch of different grass tiles

[@roadtopro-rtp695]

Question: How do you figure out the size of your map???

[@gingerageousgames613]

I just used trial and error. Make it big enough to cover the screen then adjust the noise parameters (period etc.) till it looks nice.

[@fouzi6084]

how to do a minimap with procedural generated worlds ?

[@dandymcgee]

How would you let the player move around in the world? Would you run all of this code every frame after sampling the noise function?

[@gingerageousgames613]

No. You would run this code once at the start of the scene. If you wanted a new map then you could re run the code.

[@samuelhugo3387]

If you can make a tutorial on how to place interactable objects like haravstable plants or openable chests randomly in the correct places on top if this map that would be great obviously you don't want trees to spawn on the roads also if youwant random buildings to spawn you might want a certain amount of distance between them minimum and also a rarity to determine odds of it spawing these are essential things to know for developing proceedural games so I am sure the comunity will love a video on it

[@MrLuizhausen]

Look at Godot4s new TileMap features. It has the option to define Scenes as tiles! It is still in beta, but it works rly well.

[@arcticblitz9630]

My generation seems to stop at the edge of the screen and when I added a player, I figured out that no matter what, the generation doesn't go any further. Any idea how I can make the generation infinite

[@rogerlopez6582]

Maybe increase map_size var?

[@djtatertot1361]

What are the cap variables used for?

[@roadtopro-rtp695]

Question: how do I make it so I can fall if i collide with the empty map

[@gingerageousgames613]

Give a collision shape to the hole tileset. Then use the body or area entered signal (depending on what your player is) to trigger a falling animation which will probably be mostly scaling down the size of your character and setting it to a dead state as to stop the player from being able to move any more. Edit: It might be easier to trigger the animations with an area on the player that detects the hole collision shape.

[@roadtopro-rtp695]

@@gingerageousgames613 thank you so much

[@abdellatifdev]

Good video but you probably could use map_size instead of Vector2(map_size.x, map_size.y) because map_size is a vector2 itself

[@gingerageousgames613]

Close. But the map_size variable finds the size of used tiles in a tilemap. This is procedurally created meaning the tilemap is empty and it is generated at runtime. So we have to define the size of the map we want. After it is generated then map_size would work but I would hope it is the same as the original variable I created.

[@abdellatifdev]

@@gingerageousgames613 my point is map_size is a const during the run time so it gonna give the same effect but i think writing map_size directly will make syntax cleaner , could save few seconds of creating new vector each time in the for loop

[@PikCelAlien]

Can you make video about infinite tilemap generation?. I can type infinite terrain script. But i don't know how to remove tiles when player moving. I use clear() but it removes all tiles

[@gingerageousgames613]

I will put it on the list. To get you started to delete a tile is the same as placing except the tile number is -1. set_cellv(Vector2(3, 0), -1)

[@tiradentesmonotrundle7841]

Nightmare, can you make this script available somewhere? I can't find a good tutorial of infinite terrain in any video

[@ShawnMcCourtB]

@@gingerageousgames613 I'm curious about this as well. I can't find a good tutorial to make this scale infinitely. Any advice?

[@gingerageousgames613]

@@ShawnMcCourtB This video gets you 90% there. When the player moves you would track to see if you need more tiles. The reference the noise texture like in this video. Usually you would do chunks of 10 or so tiles so do have to run the code as often. Then when you add more you just delete the same amount from the other direction. I can add it to the list of tutorials to do but it will be awhile.

[@ShawnMcCourtB]

subbed for the quick response! would I scale the map size down to 10? Or create a separate function that looks for player position and then looks if it needs to generate more tiles if in a certain range? Would I call quadrant size perhaps?

[@devinkrike5968]

Isn't calling for loops in each function detrimental? why not just draw all layers in 1 for x,y loop?

[@gingerageousgames613]

Your probably right. It doesn't run every frame so I didn't really worry about optimization.

hi, can you share the code? or the project ? thanks!
