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
        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
        )
        Player:TeleportToCoords(X, Height, Z)
        Player:SendMessage(cChatColor.Yellow .. "Cords")
        Player:SendMessage("X: " .. X)
        Player:SendMessage("Y: " .. Height)
        Player:SendMessage("Z: " .. Z)
    end
    return true
end 

That's really weird. Could you add a "print(X, Height, Z)" before the TeleportToCoords line? And perhaps add "print(Height)" after the TryGetHeight function.

Its a madness. Values are great, teleportation should work :/

Yeah, really strange indeed. I'll try to reproduce the issue.

Oh, I believe ChunkStay is async. Because of that the Height variable isn't filled when trying to teleport the player.
If you move the teleport/sendmessage code in the function where you get the height it should work properly.

And don't forget to use

Code:
Player:SendMessageSuccess("Teleported to coordinates: " .. X .. etc.);

That's a matter of preference. I personally think they look awful, and I will never use them.

What I suggested should already work. ChunkStay ensures that the chunk is loaded.

: Your code is wrong, you're using function DoCheck() before you define it. Also, ChunkStay ensures that the chunk is loaded so checking is not needed anymore, just teleport.
