Collision not happens?

I am trying to implement waterdrop falling.

I designed an emmiter, which emits waterdrops. It's name is "Dropper". The name of drop sprite is "Drop" and it has bullet behavior.

Once appeared, drops fly down.

At the ending point I placed a sprite, which I was thinking to animate drop arrival. It's name is "Faller".

I made the following event

Unfortunatly, collision does not trigger.

How to make correctly?

Seems to me the collision should work perfectly..

If you add a destroy drop action to the on collision event you'll see..

I think that your start animation from current frame action doesn't really do anything.

If destroy drop doesn't work, you could always check your collision polygons..

Either your collision polygons are wrong, or the bullet is too fast for it to register
