Conditional animation

[Dan Marino]

Hi all,
How do I create an animation that is triggered based on a condition that depends on other animations?



For example:
There are 10 objects on the slide: obj1, obj2... obj10.
I devide them to pairs, e.g. obj1 with obj5, obj2 with obj3...
For each object, there is an animation that is triggered when user clicks on it.

I need to create a additional animation (let's name it ANIM) that happens only after user clicks a pair sequencially.
e.g.
obj1 is clicked, then obj2 - ANIM should not be animated.
obj1 is clicked, then obj5 - ANIM is animated.

Any idea?
Dan.
