    GML About variables and global variables

    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...
