How do I Fix Collision problem,

i shot an arrow , and it hits wall, got pinned.

When on collision with the wall it will substract 1 from remaining.

but sometimes it substract more than 1 , sometimes 2 or 3. How is that.?

Not everytime, but sometimes really it has more collisions than 1. How would you solve it

Can you provide a .capx ?

Either a problem with your events, your collisions polygons or <unknown> other. Hard to say from the description.

Try and add a Trigger Once while true condition to see if that helps.

i will try the option Zenox said, and if it wont help i will upload capx, thank you

Anyways may i know what problem with colision polygons it could be? Any experiences?
