This is to provide parameters to loading Actor definitions, in a way that
does not need to be explicitly propagated to nested definitions; I want
loading a sub-definition to remain a simple function call with no mandatory
(prescribed) parameters. This provides a general context to pass information
to Lua about what it's loading, such as LoadingScreen.
These are scoped to the running thread, unlike global variables. This prevents
possible threading problems.
All thread variables are scoped: set a variable, do something, unset it; when
finished, all thread variables are unset.
These are no longer available after load. By design, to use these later,
use upvalues:
local color = lua.GetVar("color");
return Def.Quad {
OnCommand=cmd(diffuse,color);
}
