Find out BlockID on Cords

[moiko89]

Note that this function only works as expected if the chunk which you're querying is loaded. If you have a reasonable doubt that the chunk may be unloaded, you'll need to use the cWorld:ChunkStay() method to force-load it.

I have two function with a little difference. But the first one works fine and the other one works not. In the first function (LoadBedBlock) can i use "Height" out of the inner function and in GetRandomHeight i cant use "Height" out of the inner function, why?

Result:  LoadBedBlock         Height: 64       IsLaoded:      true

PHP Code:

function LoadBedBlock(X,Y,Z,World)
    local _, Height
    local BedBlock
    World:ChunkStay({{math.floor(X / 16), math.floor(Z / 16)}}, nil,
                        function()
                                _, Height = World:TryGetHeight(X, Z)
                                --print(X, Height, Z, _)
                        end
    )
    print("LoadBedBlock ","Height:",Height," IsLaoded:",_)
    BedBlock=World:GetBlock(X, Y, Z)
    return BedBlock
end 


Result: GetRandomHeight         Height: nil      IsLaoded:      nil

PHP Code:

function GetRandomHeight(X,Z,World)
    local _, Height
    World:ChunkStay({{math.floor(X / 16), math.floor(Z / 16)}}, nil,
                        function()
                                _, Height = World:TryGetHeight(X, Z)
                                --print(X, Height, Z, _)
                        end
    )
    print("GetRandomHeight ","Height:",Height," IsLaoded:",_)
    return Height
end
