First of all get Flash. Only costs you about 5000€ when buying with developers license
well or get the student version for 45€ x|
Then create one layer and add a script to the object. - make enough frames for your anim so you have one or two in idle state - the last one says:
goToAndPlay(1);
This will loop the idle anim.. Then on the object you add:
on(_this.click)
{
goToAndPlay(3);
}
3 is your splatter anim in this case. so when you click it it starts hopping to the splatter anim. on the last frame it hops to frame 1 again which goes to frame 2 which loops the idle anim.
Can be done easier ofcourse but this is the beginner way imo.
