How do I push + set a sprite angle to an opposite direction?

https://www.dropbox.com/s/qojcrl4jg05rv1r/push.png?dl=0

I need help making the enemy sprite face the opposite direction whenever its near the player Line of Sight.

I making a battle arena game, and whenever the player double taps the screen, the player sprite creates a wave blast that pushes the enemy sprites that are near it's LOS. I want it to push and rotate the enemies current angle away from the player sprite.

Thanks in advance!

You can do a On Create Blast Wave check.

Followed by Pick All Enemies by Evaluate.

Then evaluate for a distance check.

distance(Player.X, Player.Y, Enemies.X, Enemies.Y) < 400 (or whatever pixels distance you need).

Set Enemy Angle to whatever angle you desire. If its away from the player, you can set it to Player.Angle - 180. You can add random elements into it as well.

The above is run whenever a blast wave is created.
