How to scale character up and down with keyboard buttons?

I wanted to add something more, sorry for this :slight_smile:

I also want the ball to go from x1 y1 z1 to x0.9 y0.9 z0.9 and so on until x0.5 y0.5 z0.5 when i press A and vice versa, so i can see the scale down and scale up when i play, if it’s even possible? If it’s possible that would be nice :slight_smile:
