Actor heat

Actor.heat

This Property represents the heat of an actor, as in the current temperature. Basically, the thing that will kill an Actor when you either shoot a plasma gun at it, or it falls into lava. It should be noted that setting it to a negative value outright will not cause an error, but setting it to a positive value without the proper functions called before will.

Returns

Heat as an integer.

local chosenActor = API.getPlayerActor()-- Use the modding API to get the player Actor
chosenActor.heat = chosenActor.heat - 100 -- Notice it must be set relatively. 

local Newmonster = API.getPlayerActor()
Newmonster:updateHeatEffect(100, Newmonster.heat+1) -- I believe these two functions are interchangeable. 
Newmonster:addHeatEffect(Newmonster.heat) -- ^
Newmonster.heat = Newmonster.heat + 1

-- You need to call all of those to set the heat to a positive value.
