RandomTP

[Keith]

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

PHP Code:

function Randomtp(Split, Player)
    if (#Split ~= 1) then
        Player:SendMessage("Usage: /rtp")
        return true
    else
        X = math.random(-2000, 2000)
        Y = math.random(40,70)
        Z =  math.random(-2000, 2000)
        Player:TeleportToCoords(X, Y, Z)
        Player:SendMessage(cChatColor.Yellow .. "Cords")
        Player:SendMessage("X: " .. X)
        Player:SendMessage("Y: " .. Y)
        Player:SendMessage("Z: " .. Z)
    end
    return true
end

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 :

PHP Code:

        X = math.random(-2000, 2000)
    Z =  math.random(-2000, 2000)
    Y = Player:GetWorld():GetHeight(X, Z) 


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)

PHP Code:

function Initialize(Plugin)
    Plugin:SetName("RandomTP")
    Plugin:SetVersion(1)

    cPluginManager.BindCommand("/rtp", "randomTP.rtp", Randomtp, " ~ Random Teleport");

    LOG("Initialised " .. Plugin:GetName() .. " v." .. Plugin:GetVersion())
    return true
end

function Randomtp(Split, Player)
    if (#Split ~= 1) then
        Player:SendMessage("Usage: /rtp")
        return true
    else
        X = math.random(-2000, 2000)
        Z =  math.random(-2000, 2000)
        local IsChunkLoaded
        local Height
        IsChunkLoaded, Height = Player:GetWorld():TryGetHeight(X, Z)
        Player:TeleportToCoords(X, Height, Z)
        Player:SendMessage(cChatColor.Yellow .. "Cords")
        Player:SendMessage("X: " .. X)
        Player:SendMessage("Y: " .. Y)
        Player:SendMessage("Z: " .. Z)
    end
    return true
end

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

[NiLSPACE]

Ooh, I see the problem. Try:

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

[Keith]

PHP Code:

argument #3 is nil ; 'number' expected 


[NiLSPACE]

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