Constant Force 2D

Switch to Scripting

Constant Force 2D is a quick utility for adding constant forces to a Rigidbody 2D. This works well for one-shot objects like rockets, if you want them to accelerate over time rather than starting with a large velocity.

Constant Force 2D applies both linear and torque (angular) forces continuously to the Rigidbody 2D, each time the physics engine updates at runtime.

Properties

Property: Function:
Force The linear force applied to the Rigidbody 2D at each physics update.
Relative Force The linear force, relative to the Rigidbody 2D coordinate system, applied each physics update.
Torque The torque applied to the Rigidbody 2D at each physics update.
