Cuberite Forum

Hi, its my first plugin in LUA.
I don't know how to check the ID of block in random XYZ position.
Sometimes its move me into blocks. I want to teleport olny on grass, sand, dirt.
Please help

Hello, and welcome to the forum

You can use this:

local BlockID = Player:GetWorld():GetBlock(X, Y, Z)
if ((BlockID == E_BLOCK_GRASS) or (BlockID == E_BLOCK_DIRT) or (BLOCKID == E_BLOCK_SAND)) then
   -- Teleport the player
end

But keep in mind that a player can now be teleported inside block. If you use this:

local X = math.random(-2000, 2000)
local Z = math.random(-2000, 2000)
local Succes, Y = Player:GetWorld():TryGetHeight(X, Z)

the player should teleport to the highest block instead.

I used :

Trying to use TryGetHeight(X, Z), returned bool value and error in colsole.

TryGetHeight() returns two different variables on completion. The first is a boolean which indicates if the chunk is even loaded and a second which is the highest block point on those X and Z coordinates. You would have to set TryGetHeight() equal to 2 variables and use the second one to get the right value.

local IsChunkLoaded
local Height

IsChunkLoaded, Height = Player:GetWorld():TryGetHeight(X, Z)

The chunk is most likely not loaded. Try this:

local X = math.random(-2000, 2000)
local Z = math.random(-2000, 2000)
local _, Height

local World = Player:GetWorld()
World:ChunkStay({math.floor(X / 16), math.floor(Z / 16)}, nil, 
	function()
		_, Height = World:TryGetHeight(X, Z)
	end
)

It will ensure that the chunks are loaded and then get the height.

Btw, I didn't test this code. There might be a syntax error in it.

NiLSPACE,


It works with GetHeight(X, Z). But sometimes it is teleporting me before chunk load, and im locking in blocks

Ooh, I see the problem. Try:

World:ChunkStay({{math.floor(X / 16), math.floor(Z / 16)}}, nil, 

That's weird. Could you post the whole code + whole error?
