Lua error please help

I made a post a while ago about this sorry for posting again, just ignor that other post…

[addons\ls_core\lua\entities\base_gravity_control\i nit.lua:102] attempt to compare boolean with number

Thats the error and the files are below, ive gone over it but im not so familiar with lua. if i can get some help i would be greatly appreciative.

Put it in lua tags please.

What does GetGravity() return?

Seems like it’s returning a boolean rather than a number.

The GetGravity() method returns something wrong for Entity.Enviroment.

Yeah man, ya ever try slapping
[Lua]
MsgAll( ">> Hey, the gravity is “… tostring(self.environment:GetGravity())…” which is a “…type(self.environment:GetGravity())…” type of data!
")
[/Lua]
Just before line 102?

Tell us what that returns

PS since that shits in think its gonna spam your console like a bitch lol

I can’t even find it’s declaration. Is it in spacebuild gamemode? And could you send a link to that?
