Release Object: Release an object that has been picked. This object will no longer behave like projectile. The picked number will be subtracted by 1.
Picked Number: The number of objected that has been picked by projectile.
Reload Time: The time that it takes for the projectile to reload.
Auto Reload: The projectile will reload automatically after it's being shot.
Delay for Auto: If Auto Reload is checked, how long will it take to reload after the projectile is shot.
When applied for the first time, Projectile is set as a dynamic physics object spring constrained to the world. The spring property is equal to the force in the basic control. You can change its target from the constraint panel. Increase damping in the physics spring constraint panel to reduce the swinging effect.
