Would using bullet behavior be best? I saw this idea suggested:
"You could use the bullet behavior:
+PlayerSword collides with Enemy:
---Enemy:Bullet:Set speed: 400
---Enemy:Bullet:Set angle of motion: angle(player.X,player.Y,self.X,self.Y)
---wait 1/4 seconds
---Enemy:Bullet:Set speed: 0"
But I wonder if this would conflict with the bullet behavior the walkers already have...
