It would be nice if there was a system which shows global and actor variable values in game mode. For example when F1 is down or something. I'm sure many game makers have done temporary text actors for testing complex systems...
I can't die, I already tried ~on the forums since GE 1.3.3~
Rappers are not intelligent? O_O loljk, anyway, I also use text actors for debugging purposes, clone them and let them show different variables according to their clone index, that way I save quite some time.
