I'm using bullet behavior to move a sprite in a straight line between different points say A,B and C. Sprite starts with bullet behavior moving toward toward point A, hits point A then changes direction to point B and so forth, in a straight line. I'm noticing on some devices I am getting a weird lag thing happening where the sprite hits point A then changes direction to point B but instead of moving to point B in a straight line it kinda swerves like a drunk driver on its way to point B and then swerves again on its way to point C, and the game starts to lag pretty bad whenever this swerving happens. The devices I am testing on are all high end, able to handle all the newest 3d games at 60fps so I don't think its the devices causing it to lag. Not sure what could be causing this, anybody else have similar problems with the bullet behavior?
