Linear Movement

Move objects on a straight line.

Authors and contributors to this experimental extension: 4ian, Jurfix.

Move objects on a straight line or according to their angle.

It can be used for simple enemies or bullets. It's usually not adapted for players (other behaviors are a better choice) or bullets fired with the actions provided by the "Fire Bullet" behavior (these bullets are already moved using a force).
