I currently have a U shaped ramp (bitmap) and have a ball (motion tweened) to the shape, rolling down. A tree ( bitmap) will be kept somewhere on the ramp and i need the ball
1) to begin disappearing /going out of sight as it approaches the tree and out of sight for the period behind the tree
2) still do number 1 but specify the ball to stay X period of secs before it comes out behind the tree
-Many thanks for helping me with this. I am a beginner and have looked at tutorials but unable to do this.
convert your tree to a vector (select it>click modify>trace bitmap) so you can remove its background. then place the vector on a layer above your tweened ball layer.
