Godot 4 TileMap Tutorial Ep 8 | Procedural Generation with Terrains

[@JackieCodes]

Hey guys! I uploaded a vid explaining the changes of the tilemaps for Godot 4.3, check it out! kzbin.info/www/bejne/aWjQmWmlo7B6pMk

[@adrianvazquez8686]

I can't wait to finish this series!!! I'm really excited on making my farming game!! I've been following all your tutorials and let me tell you they're great!! I'm new to Godot so I really need your tutorials to make my first "Stardew Valley" game!! Keep it the good work!!

[@hawkgamedev]

hey Jackie if you ever read this, just to let you know you can make the editor check for errors faster so the red highlight goes away faster, Editor Settings> General > Text Editor> Completion> Idle Parse Delay.

[@233piotrek]

As a beginner game developer procedural generation seemed like black magic, but this and previous videos explained everything so neatly, thank you very much!

[@CyprusLLama]

This is a great instructional series, I'm finding it very helpful! Something that can be done to avoid modifying the ranges based on the noise type is to run all the values through a normalising function which converts the given value to a number between 0 and 1 based on the min and max. In pseudocode it would be something like: func _normalise(val, min, max): return (val - min)/(max - min) Obviously this would require looping through the noise values once before setting the tiles, but it allows you to use all the various noise types without having to cusomise your mapping code to each type individually.

[@JackieCodes]

Thanks so much for the improvement! I will check the code out!

[@skell_jams]

does abs(terrain_noise.get_noise_2d(x, y)) accomplish the same thing? I think using the absolute value would prevent needing to rewrite the loop while still having your colorramp magic numbers

[@CyprusLLama]

@@skell_jams I don't think that would do the same thing, because the absolute value of a number is simply the number value without a sign. So for example, in a range of (-0.7, 0.5), taking the absolute value would give you a range of (0, 0.7). More importantly, however, is the fact that values of e.g. 0.2 and -0.2 would evalutate to the same if you take their absolute value, which can significantly skew the output and would probably break the randomness of the noise in strange and unexpected ways.

[@adammcelroy9853]

This series has been so helpful probably the best and most informative since ive started godot last month. Really made me more confident in actually making games. Looking forward to seeing whatever comes next for your channel

[@Bielmeloba]

Great video, i love how you explain things! Just only one thing: If you add collisions to the water, all of your cells will have collisions. To solve this: Create another water atlas, one with collisions and the other without. The water under the ground has to be the one without collisions, and voilà! In code (Created this walkable_water_tile_atlas): if noise_val > 0: sand_data["array"].append(Vector2(x,y)) tile_map.set_cell(water_layer, Vector2(x,y), 0, walkable_water_tile_atlas) else: tile_map.set_cell(water_layer, Vector2(x,y), 0,water_tile_atlas)

[@gabrielrezende2525]

thank you so much for this solution!

[@891Demonkiller]

Thanks for this. Rather than a new tile atlas, I was able to get the same result using an alternative tile in editor go to TileSet > Select the water tile > right click "create an alternative tile". It spawn to the right of you TileSet Then paint the alternative tile with the physics layer for collidable water. Hover over the alternate tile to see its alternative number #under the Var water_atlas = Vector2i(0,1) I added a new variant var water_atlas_collision_alt = whatever that alternative number you saw was if noise_val > 0: tile_map.set_cell(water_layer, Vector2(x,y), source_id, water_atlas) else: tile_map.set_cell(water_layer, Vector2(x,y), source_id, water_atlas, water_atlas_collision_alt)

[@KikiJynx]

You explaining how to move the sprite ysort stuff just solved a logistics issue I’ve been losing sleep over for 3 days 😭 thank you so so much ❤

[@dovos8572]

for tilemap layers it really helps to make an enum like enum Layers {Water, Ground1, Ground2, Cliffs, Environment} it counts up from 0 from the left and you get autocomplete for it. set_cell(Layers.Water, pos, 0, atlas_pos)

[@NathanWoyessa]

do you know whats the most efficient way to load more chunks as you go out so its infinite? I tried using a basic chunk system where it devides your position by the width and height to get a chunk. But its hard to load and unload chunks without overwriting existing ones

[@rindallbroxmitten]

Thank you very much for this tutorial series. Very clear, concise and with a flair of humor. Can't wait for another Godot hit song! :p I usually only sing about potatoes or whatever else I'm cooking.

[@federicodelcid7876]

Perfect Playlist, thank you so much ❤

[@gushcraftgaming]

Don't know if anybody else had an issue with the cliff textures having a weird issue graphical issue of using the wrong texture, but I found creating a tile on the blank location where we normally fill in all 9 sides fixed it. This might've been mentioned somewhere in the previous guides but I'm not entirely sure. Edit: I just realized the sprites that were used in the previous guides were updated with newer sprites, and the cliffs have a filled in tile.

[@JackieCodes]

Yea! Thank you for the comment! Updated sprites are on itcu guys!

[@hawkgamedev]

Another solution you can play around with is using the same layer as grass as a copy and place trees only with a new tree terrain with the probability property built in Godot's terrain system.

[@cyborganic]

So helpful, thank you for this series!

Another great tutorial, thank you!

[@jRsqILVOY]

Your tutorials are amazing! Could you do one on Navigation with the TileMap too please?

[@SomeRandomWittyName]

Great video, Your approach seems easy to implement into already existing projects. How ever, how would you ensure that all map parts are reachable? For example at the moment some parts of a land mass would become unreachable if player can cross water. Are there plans to include that into tutorial?

[@refeals]

love this series

[@BrunoFernandes_84]

i learn a lot since i start follow you, appreciate. Just one question is this valid for isometric tilemaps? or it works diferently? Cheers

[@Theonewhoknows98]

i can use the x,y values to instance nodes too? like treasures, enemies etc

[@gamegenius126]

Maybe someone already asked but... I'd like to see how to make this map generating in runtime and how to deal with memory stuff (I mean how to work with chunks as minecraft does). Because now, as I can see, we are hardcoding our world size values. And thanks for this amazing series! Helps a lot for starting in game development!!

[@mohammadfakhraee133]

You can generate map block by block. Declare a specific map width and height and when user gets near to edges you call generation for new blocks near the edges. Also I guess Godot map has a cache strategy (I'm not sure about it you can search)

[@StrangeObscureStories]

Amazing tuts

[@nelsonguedespaulojunior977]

Hi, very nice tutorial series. Can you do some video talking more about collisions? You created one very fast for the cliffs, but what if we want to climb in the cliffs for instance? Or maybe there's a road to the top and we want to walk on top of it, but not fall? How about not being able to walk on water?

[@response-status-200]

Thanks 💚

[@rinevardmercy]

thank you so much!

[@ArteTutos]

Hi, just in case great video! but I've a question, the set_cells_terrain_connect() function in Godot 4.3, how it would change to create the procedurally generated map? I'm using Godot 4.3 in this moment, but I don't know how my code would change with respect to create a prodecurally generated map, can you help me with that?

[@yahshek]

yo jackie all good? Curious if u are planning to continue this series or you are on a break?

[@felipearisteu]

How can I add a vignette to this noise? To create only water on the edge of the entire map, like in Don't Starve

[@mandu9520]

You would probably want to use a falloff map

[@99JasonKim]

quick question(maybe dumb one).how do you know the max and min value of noise? did you map all the possible value in the tilemap?

[@99JasonKim]

ah, no problem. i saw the clip.😆

[@JackieCodes]

@@99JasonKim :p each noise setting is diff so you gotta map out each time

[@99JasonKim]

@@JackieCodes that's really good tips i learned~

Can you save the world you created so you can modifiy it?

[@CharlesLang676]

would really love a video where you build the player? Maybe it got lost, but its no longer within the playlist

[@nobytes2]

All you need is a 2d sprite and add animations to it for the movements you want, and add input.

[@QuanHu-ww1rn]

Is the series over?

[@Sean_Codes]

Is there any planned video about procedurally generate enemy based on the map? For exaple a crab enmy that's spawn only on the beach ecc Anyway thank you for your videos they are really helpful, keep going 😃

[@JackieCodes]

Yes :)

[@rindallbroxmitten]

Wouldn't that be the same sort of procedure we did for the palm and oak trees? Make a new noise map for enemies, set a range between the min and max where you want enemies to spawn, then check the noise map of the world and set a range for that (so maybe only on sand for crabs) and if it's in those ranges, spawn an enemy on the x,y of the tile map. So don't put down a cell, but instantiate a crab.tscn.

[@nobytes2]

@@rindallbroxmitten yeah is the same procedure, you would only put crabs on the beach layer, Dunno why bro is asking lol we literally got 8 videos on tilemaps on just about everything you need to know to build anything.

[@thomasdefranceschi758]

Instead of a grass array for multiple grass tiles, if you just paint all of them with the same terrain and bitmap as the full grass tile, they will be randomly selected by the terrain generation. At least that's what my test project did. I'm not sure how they will behave if you update the terrain through code later during the game...

[@JackieCodes]

Ohh I will test this out! Thnx for the heads up

[@jesusrubilar6673]

Hi! this is a great help for those who want to make maps with saving time, but now in godot v4.3 the tilemap is getting old :c now are the tilemap layer, i think the process is the same but i would like if you can explain me more about the new changes :c pls

[@johnborg305]

Could you please do a new updated tutorial now that tilemap is deprecated

[@mandu9520]

The only real difference I found is that tilemaps need a layer int at the start of set cell, but since tilemap layers are all one layer they don't need that and will throw an error. If you erase the 0 at the beginning of set cell it should work.

love your vids. but i have an error *AGAIN* and this time i cant figure out why o_O getting this error code "invalid type in function 'set_cell' in base 'TileMap'. Cannot convert argument 4 from Array to Vector2i." on ""if noise_val < 0.35 and tree_noise_val > 0.8: tile_map.set_cell(environment_layer, Vector2i(x,y), source_id, oak_tree_atlas_arr)"" been trying diffrent solutions but as far as i can see with my dyslectic eye, codes identical o_O

[@JackieCodes]

I will give you the answer but I will walk you through the error code. You have a problem with the oak tree atlas variable. You're using oak tree arr instead of oak tree atlas, basically you're giving an array variable and not the atlas coords
