I'm hoping this is straight forward.
I have a sprite moving up the screen.
I have it set so when key is pressed the sprite moves left & right at angle.
keyboard-right arrow is down-sprite-move 1.5 pixels at angle 0
keyboard-left arrow is down-sprite-move 1.5 pixels at angle 180
I'd like to make it so the longer the key is held down, the more the angle increases.
Hope that makes sense.
