Get World Height?

So, this is one of those things I could find out with extensive testing, but it'll be hours until I get home and I'm also hoping somone else will be benefitted by this post.

 

Simple question, then: world.getHeightValue(x,z) will return what Y value, by definition? And more specifically, if I use this function in an area where there's a tree, will it get me the height of the leaves or the height of the ground under it?

welll .. you could have looked at the code directly (unless you dont ahve access from where you are) but it will return the first opaque bloc (aka leaves no, wood yes)

Yea... actually no. I'm using that function to try and find trees for my worldGen. My problem, though, is not that the gen is made too early but:

 

a) This function returns the y value of the block just above the top most for given X and Z(i.e., it's an air block)

 

and b) It does not make any distinction between solid blocks or not. I got both water and leaves on the position just below that value.

 

Thanks for the prompt reply, guys, but you might be thinking of a different version of the code(I'm working with 1.5.2).

for(int i = 0; i < 256; i++){
    if(world.getBlockID(x, i, z) == 0){
        return i;
    }
}

 

and or check that the block id is part of those you want to be considered max

I am doing loops, but trying to reduce them. I already get some hiccups when generating new chunks as it is, I'd like my code to be minimally leaner.

 

Besides, I can use getHeightValue, I just need to check a few blocks down in these cases. I wanted to clarify because the documentation is vague and the code isn't much better either(it just takes this value from an array, but doesn't explain where this array is filled).

    • I'm researching the how to create biomes in json. There is a great tool for creating the jsons online. Using the vanilla `river` biome, I want to essentially create a custom disk feature that mixes 3 blocks instead of a single-block provider. Any ideas on where to start with that?
    • I figured out what was wrong ... you can spot it pretty quick most likely: { "type": "minecraft:smelting", "ingredient": { "item": "minecraft:gold_nugget_ore" }, "result": "minecraft:gold_nugget", "experience": 0.25, "cookingtime": 150 }   ... so, after changing `minecraft` to `foundations` for all the custom items and all the recipes work. Well that's what copy/paste will get you. One last question about recipes, though. What does the following json key/value do in the game? "group": "copper_ingot"

    • Is there a way to create a custom map marker for a custom structure/biome (same as a vanilla mansion)?
    • I’ve scrounged the Internet for solutions and found absolutely nothing that has worked for me I have posted my code in a GitHub Repository. I bet the culprit is somewhere in the Container or TileEntity classes (Furnace packages are in blocks/coke_furnace or blocks/foundry) PS I know I’m on 1.12.2 and that it’s not supported I don’t want to update my game or my code. Lol It’s my favorite version and the most widely modded. I don’t plan to release the mod, I’m just customizing my game to my will. I’ll send it to friends but that’s it.
