Error in entity parsing code

Recommended Posts

I want to use the following code to get entities near each player:

    inst:DoPeriodicTask(1.0, function(inst)
        local pp = inst.Transform:GetWorldPosition()
        local ents = GLOBAL.TheSim:FindEntities(pp.x, pp.y, pp.z, 100)

However it crashes my game with the following error:

[string *../mods/MyMod/modmain.lua"]:25: attempt to index local 'pp' (a number value)
LUA ERROR stack traceback:
	../mods/MyMod/modmain.lua:25 in (field) fn (Lua) <23-26>
      scripts/scheduler.lua:177 in (method) OnTick (Lua) <155-207>
      scripts/scheduler.lua:371 in (global) RunScheduler (Lua) <369-377>
      scripts/update.lua:185 in () ? (Lua) <164-243>

Any idea what I'm doing wrong? I'm brand new to modding DST so I don't know if I have a syntax error or what.

This being said, you can use GetPosition but it's a vector3:

local pp = inst.Transform:GetPosition()
print(pp.x, pp.y, pp.z) -- By part manually
print(pp:Get()) -- Returns the x, y, and z components

There are advantages in keeping it as a Vec3 as there are wrapper functions with the object type to make doing math with them simpler.

They're all defined in scripts/vector3.lua.

It worked, thanks guys. Though I don't get why pp.x etc... don't work and you have to use pp:GET(), as surely if you can print them they're public members and can be accessed directly? At any rate that doesn't matter to the mod, which now works as intended. Thanks again!
