    SOLVED why does 'is_undefined' NOT prevent undefined variable crashs

    I simply have this code: if is_undefined( database[i, oPlayers] ) { //stop } and still the game crashes saying that is_undefined( database[i, oPlayers] ) is not set before reading it! I acctually USE is_undefined to PREVENT this error! Why does it not work?

    GML About variables and global variables

    I wanna know about the difference between them, is that variables are attached to the object only, and you can't use it in another object and global variables are available across all objects? I don't know if I am right.

    if the variable for nearest instance = 1: stuff happens

    Hey, basically, I want to make it so that if an enemy object with a certain variable (effect) set to 1 comes near enough to another enemy object whose var is still 0, then that enemy object's var 'effect' also becomes 1.

    Design Questions about Delta time, lag with incremental/click based game.

    1. Is Delta timing good for a incremental/click based game? 2. If I have variables doing calculations per step, and the game lags, will it cause issues for me? Ex: if I had two variables relying to be in sync, and become out of sink due to lag. Or is that lag just voided steps and the...
