I know the use of globals is frowned upon but I was meessing around with them and have observed some strange behavior. Just wondering if the following scenario makes any sense:

1. defined a global _G.testVar in main.lua
2. main.lua loads menu.lua
3. menu.lua sets testVar=0 and loads game.lua
4. game.lua increments the value of testVar and the reloads menu.lua
5. If I print out the value of testVar in menu.lua it is 0.
6. If I then reload game.lua the value of testVar is once again incremented... to 2. Shouldn't it just be 1? The global value was reset to 0 by menu.lua. It seems like a new instance of the global variable is created for each .lua file.

I can't figure out why I am seeing this behavior. Any help would be greatly appreciated! Thanks!

@txmarsh, you might want to post your relevant code, i.e., all references to _G.testVar in main.lua, menu.lua and game.lua that you have.

Are you sure it's defined in main.lua?

When you are calling the testVar variable in the various lua files are you using "_G.testVar" or just "testVar" to access it?

I was using just testVar... when I try _G.testVar then I always get 0.
I guess this is not normal... I'll do some more research.
Thanks!

When you increment it are you also using _G.testVar, or not? If you define something as a global using _G. then you need to use that every time you refer to it, as testVar and _G.testVar are two different things.
