Scratch

When I put in a fairly normal script that looks something like this onto the bullet sprite:

[blocks]<when green flag clicked>
<go to[ gun]
<show>
<repeat until><touching[ << enemy <or> edge >>
<move( 50 )steps>
<wait( 0.01 )secsc>
<if><touching[ edge]>
<broadcast[ edgetouched]>
<hide>
<change{ enemy health }by( -15][/blocks]

The broadcast edge touched is so the enemy doesn't lose health if you hit the edge. However, this works like it should.

But if the enemy has a script that looks like this:

[blocks]<when green flag clicked>
<show>
<repeat until><( <{ enemy health }> <<> 0 )>
<point towards( hero
<move( 4 )steps>
<wait( 0.05 )secsc>
<switch to costume[ dead[/blocks]

It now works approximately 30-70% of the time. I know it's caused by the movement script, but frankly I have no idea how to fix this.

Any ideas?
