Class Documentation
Edit documentationA physics modifier that accelerates the particles. It
holds two independent accelerations: a local one in the axes of the particle's reference
frame and a world one that keeps its world direction. On each step, before the
integration, each acceleration is Initial * Keyed and is added to the step's
acceleration. Units are world units per second squared.
The position-based model applies the step's acceleration as a * dt^2 to the position
and a * dt to the velocity, so the particle keeps the speed it gains. See
VfxModularPhysicsComponent.
Properties
World acceleration, evaluated once per particle at spawn. A constant (0, -g, 0)
here is gravity. If this driver is null, the world pair does nothing.
Multiplier on InitialLocalAcceleration, evaluated on every step.
Multiplier on InitialWorldAcceleration, evaluated on every step.
