I've hunted the forums, but not found what I need.
I have a Tree sprite made of 10 sprites. A bit like this...
F=Foliage, T=Trunk and B=base.
The plan is, when I collide with the Trunk, the foliage shakes.
The Foliage sprites are in a family called 'TopOfTree'
When the player collides with the 'T'runk, I enable the Sine behaviours that are in the 'TopOfTree' family.
How can I achieve this?
I did add the base and trunk to the family, but only the base shakes (which shouldn't shake at all). I know I need to select all the other sprites that make up the family but I can't figure out how to.
