How do I make bullets bounce off solids, but only once?

I am trying to make a game and I need a specific type of bullet to bounce off solids once, and get destroyed the next time it hits a wall. However, I am unable to do that.

On collision with wall add 1 to variable.

If variable = 2, destroy

I did that, but sometimes when I shoot the bullet, it just disappears.

Send the project, I'll take a look at it in the morning.

The problem could be that you're not resetting the variable upon the destroy.

here is the project.

The problem sounds like you are getting multiple collisions very quickly so the bullet is disappearing as the bounce variable will be greater than 2.

In the same event that adds 1 to the variable, start a timer on that instance for a very short time 0.1 or something and add the "timer is not running" condition to the event.

Thanks, I added the timer and it solved the problem.
