How do I detect collision of instances of same sprite

I have an explosion sprite that deals damage to any enemy instances. But when the explosion collides with 2 or more of the same instance, my score is only given as once not for each instance destroyed. How do I correct it?

If you put the command to add+1 to your variable within the same condition that destroys the enemy it should work. Try uploading the .capx or a screenshot of your code so we can take a better look on what's going on.

Sorry for not being able to help D:

Thanks that worked ! I added an on destroyed triggger add 1 to a global variable and placed the score after that rather then under on hp = 0.

Rayki you helped ! =D
