Get World Height?

[pro-mole]

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)

I agree with that guy ^^.  THe first opaque block from the top of the sky.  However, I want to add that if you gen your stuff too early, trees might not be in place yet.  I had that problem once.

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).

why dont you simply do a loop ?

its not gonna kill anyone

[hydroflame]

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).

but doesn't explain where this array is filled

 

well you can always follow the stack trace btw..............
