I’m making a shooting game, would like the gun to flip \_xscale when you move the gun past half the width of the stage.

Here’s the script I made which doesn’t work and is probably not written correctly:

if(\_xmouse \>= Stage.width/2){  
\_root.gun\_mc.\_xscale \* -1;  
}

Thanks ahead for your reply/answers

I guess I should also add that, the gun\_mc is following the mouse on the x axis in case anyone is confused.

```auto

Thanks Glos, you were close, the \*= is the correct usage to multiply. What I didn’t know was that the number is the percentage and not an actual number to multiply by. So the number is -100.

Only downside to the script that we have now is that it only occured once. I needed a listener or something to keep checking to see if the x coordinate of the mouse had changed.

The script that seems to be working correctly is:

\_root.onMouseMove = function(){  
if(\_xmouse \>= Stage.width/2){  
trace(“it is at more than half!”);  
\_root.gun\_mc.\_xscale = 100;  
}else{  
trace(“it is at less than half!”);  
\_root.gun\_mc.\_xscale = -100;  
}  
}

Thanks for replying!

So the number is -100?

Let’s say that your movie is 50 pixels wide:  
\_xscale= 100; // mc is still 50 pixels wide  
\_xscale\*= -1 // 100 \* -1 = -100 so mc is flipped but still 50 pixels wide  
As you can see, = -100 and \*= -1 are both the same

But what if you’ve already resized your movie, say by 50%?  
\_xscale= 50; // mc is resized to 25 pixels wide

Now, if you use \_xscale= -100, your movie is flipped but it reverts back to the original 50 pixel width. However, if you use \_xscale\*= -1, then 50 \* -1 = -50 so your movie is flipped but it still retains your amended scaling of 25 pixels.

So -100 isn’t the number in these circumstances. Hope that explanation helps.

And updateAfterEvent() might help solve the other problem…check it out in the Help files.
