For my game to start, I want the user to be pressing both Button01 and Button02.
How can I code it where I get something along the lines of:
System > If Button01 is pressed AND Button02 is pressed > goto PLAY FUNCTION
Do I need a couple of Global Variables?
eg: When Button01 = "Pressed" AND Button02 = "Pressed" > goto PLAY FUNCTION
You really should read the manual, especially the Event system.
To make the AND condition, simply add another condition below the first. Highlight 1st, right mouse, add another condition.
