    So I have this project. It is for mobile devices. I have this eye and with your finger you have to move it sideways or up and down. Not diagonal. Also it should stay within the boundaries of the eye. Someone who can help me out with this? I prefer Visual Scripting but if you can explain it in C# I might understand it as well.

    Get the vector of the start of the drag and limit it to the closest axis until the drag is released.

    Get the position of the start of the swipe, get the position X amount of milliseconds after the start of the swipe. Subtract the second vector from the first and get the absolute value of the X and Y axis, see which one is bigger. If it's X, lock motion to that. If it's Y, lock motion to that.
