Making Your Own Flash Slingshot Target Game: III

Right-click on the stone to open the Actions for the object, and insert an onClipEvent set for enterFrame. Then set up an if statement inside the onClipEvent, telling Flash that it needs to use hitTest to test the stone (this) to see if it tests positively for collision with that particular squishie (_root.squishie1):

onClipEvent (enterFrame) {
if (this.hitTest (_root.squishie1) ) {
}
}
