Bounce without collide rule

VGX

How do you make a ball bounce left and right, up and down, etc.. without using collide?

using interpolate to change the position with the ease in and out used to slow and accelerate the ball will give the effect. As the ball bounces up it slows so use the ease in and as is accelerates from the fall use ease out.

hope that helps.

You could change an objects x velocity attribute by multiplying it by -1. (Same with y velocity.)

When an actor hits a left or right wall:
change attribute: (self.Motion.Linear Velocity.X) to: (-1*self.Motion.Linear Velocity.X)

When actor hits a top or bottom wall:
change attribute: (self.Motion.Linear Velocity.Y) to: (-1*self.Motion.Linear Velocity.Y)

Give an object some initial velocity and this will get it bouncing off of the sides like an old-school pong game.
