Hey all I have an incredibly basic LUA question here. Why does Game Guru crash when I attempt to set a variable as the entity's index number?

crashes when I use either
entityindexvariable = e
entityindexvariable = g_Entity[e]

I'm just trying to make a write a global variable as the entities index so that I can do a variety of things with other entities knowing another entities index number. For instance the ability to Hide or Show other entities (without knowing their index number predetermined but simply by using global variables that were assigned the index numbers. Unfortunate GG crashes when i attempt to set these variables.

Maybe those globals are already used elsewhere and you are corrupting them? Without seeing the script or seeing any error message you may be getting I can't really do more than guess.

Best advice is don't use global variables without appending the name of the script to them and the g_ bit in front, that way you can be pretty sure they are unique.

Been there, done that, got all the T-Shirts!

Where are you calling that? To return 'e' you will need to be inside one of the related functions - I.e. init(e), main(e), exit(e) - as the (e) means the 'e' number is being passed to the functions, if you are trying to define the variable above the functions in the script it won't know what 'e' is

Thanks guys, its been a while since i jumped back into LUA. I was trying to call the value from outside of the functions, so basically just receiving a nil value. That could explain the issues. Will do another test when I get home.

EDIT: everything works fine, noob error had everything before the functions
