got nil from local x, y, z = player.Transform:GetWorldPosition()

[weire]

my code is like:

local function GetChatterEntitys(player, name, tag)     
    local x, y, z = player.Transform:GetWorldPosition()   
    local ents = TheSim:FindEntities(x, y, z, AROUND_DISTANCE, {name})

[01:04:08]: [string "../mods/workshop-3427829223/scripts/impl.lu..."]:1: bad argument #2 to 'FindEntities' (number expected, got nil) LUA ERROR stack traceback: =[C]:-1 in (method) FindEntities (C) <-1--1> ../mods/workshop-3427829223/scripts/impl.lua:1 in (upvalue) K (Lua) <1-1> u = 141425 - wolfgang (valid:false)

'Is it because the player is valid:false? why is that, it's a client player.

is it because the GetWorldPosition and FindEntities is working on client?  How do we know if a function is working on server of client? it confuse me a lot

Depending on the context of your player function, If your player is not valid yet, will not get a proper position. This can occur if a player is still loading in/out or is on the player select screen. Try making a ListenForEvent with "playeractivated" for client or "ms_playerjoined" for server.

You could check if your player is valid first before proceeding with the function.

if not player:IsValid() then return end
local x,y,z = player.Transform:GetWorldPosition()

I think a way to not have to check if a player is valid yet is using components, because components are added after a player is valid and have a Transform, I believe.

you should check the validity from Transform because it returns nil for unconstructed and (0,0,0) for deconstructed object.

Thanks! Today I learned. when this happen, the player is in the world, maybe that's because he is loading out? I'll fix it. By the way, 

 TheSim:FindEntities(x, y, z, AROUND_DISTANCE, {name})

is able to be used in server right?
