Scratch score variable doesn't go up

Question

I made a shooter game in Scratch, but my score variable doesn't go up when the plane shoots the enemy.

I use a clone for the enemy. The Score variable should go up when a Laser touches a UFO1 or a UFO2.

What is the problem?

Answer 1

I remixed you project. https://scratch.mit.edu/projects/947386913/

Main changes are in "Laser" and "UFO1"

Don't use "glide" block, because you can not do other things during moving. Use "Forever" block as main loop.
