What you could do is have the active object shoot a missle object, and do this:
Press Fire 1
-"Player" shoot "Missle" at speed 35
"Missle" is in play area
-Add to alterable value A 1
Alterable value A of "Missle > or = 30
Only one action when event loops
-Create "Mini Missle" at (0,-5) from "Missle"
-Set direction to "Missle"
-Create "Mini Missle" at (0,0) from "Missle"
-Set direction to "Missle"
-Create "Mini Missle" at (0,5) from "Missle"
-Set direction to "Missle"
-Destroy "Missle"
"Mini Missle" is in play area
-Look in direction of "Group.Enemy"
And the Mini Missle would be a Bouncing Ball movement that is moving at start, so when it is created it goes in the direction the original missle was going.
