Adds a constant directional force without affecting rotation that keeps being applied over time until cleared with [code]constant_force = Vector2(0, 0)[/code].
This is equivalent to using [method add_constant_force] at the body's center of mass.

Applies a directional impulse without affecting rotation.
2021-12-08 09:09:54 +08:00
An impulse is time-independent! Applying an impulse every frame would result in a framerate-dependent force. For this reason, it should only be used when simulating one-time impacts (use the "_force" functions otherwise).
This is equivalent to using [method apply_impulse] at the body's center of mass.
