"Set mirrored" with the sine behavior?

I have a sprite with a sine behavior, and it moves horizontally. When the sprite moves right, I want my image to face right. When the sprite moves left, I want to mirror the image so it faces left.

How can I "set mirrored" or "set not mirrored" at either end of the horizontal motion?

I'm sure there's a smarter way to do this, but here's my suggestion: create an instance variable called OldX. Every tick, set OldX to Self.X.

Then create two events to change the mirror:

if OldX < Self.X : set not mirrored

if OldX > Self.X : set mirrored

This doesn't seem to work for my game for some reason. <img src="smileys/smiley5.gif" border="0" align="middle" />

Is there another way to do this or a capx.?

Has anyone figured this out? I'd also like to have my sprite change direction based on left/right horizontal sine movement.

The capx file by A0Nasser found in this thread has a perfect example.

Works for me!
