    GML Math help

    Hi, I would like to find the formula for finding a single number (0-9) in another number. So to identify any number with a ‘9’ in it. e.g. 9,19,29,39,49,59,69,79,89,90,99. How can I code this as a formula for any number? Or is it even possible?

    GML Scale Sprites from Screen Center xy Displacement Formula

    I need to make scaled objects draw to the screen getting closer to the center as they get smaller and when getting larger further out from center (if not completely centered at 320x,180y.) I've figure out how to increase the image scales in a natural way, but the xy displacement formula alludes...

The first equality is true, the second is wrong. So I need to get the result - right or wrong equality in the variable. How to do it? I tried to...

    Legacy GM Need Coordinates Where Object Will Leave Room

    So I have an object moving across the room. Obviously, the direction and (x,y) is known about it's current vector. What is the best way to predict where (i.e., coordinates) it will leave the room? One idea I had was to use Lengthdir to add some length to the object, get those coordinates...

    Make Objects of Different Scales Line Up at Screen X Center as Parallax Across Screen

    I need objects with different scales to move at the same speed off-screen, but change speed and position so that later the horizontal center of their sprites line up in the middle of the screen if the objects were placed at the same x coordinate in the Room Editor. Creating parallax, but...
