Bouncing effects and elastics effects

i read some tutorials about some clips that includes bouncing or elastic effects, the problem is i can’t still figure out some axnscripts such as MovieClip._x*=100 or MovieClip._x-=100, what does these syntax mean anyway?

can i have some tutorial like a dribbling ball that bounces a lot then settles down after a few moment?

a += 5 means a = a + 5
the same for the rest of the operators :slight_smile:

Check this for operators explanation:

And Bit-101 has a tutorial about that (check the gravity tutorial)

No need to go that far =)
