I expect it to change when i hit the enemy with bulet

Answer 1

The forever loops that are supposed to increase score, are both under a when green flag clicked hat block. That means they only work for the main instance of their sprite; not for clones.

Both the bullets and the enemies are clones; the main instances of the sprites are invisible and do not move. That means the touching block will never detect a collision.

One solution is to replace the when green flag clicked hat block by a when I start as a clone hat block.

Another possibility is to remove the entire loop, and simply increase the score as you delete the enemy clone.

Answer 2

In the costume 2 sprite, put an if statement, if the costume 2 touches costume 3, increase the score by 1 as seen here:
