Block settings
Setting |
Type |
Description |
Mode |
Enum |
The method this Block uses to apply a force to particles. The options are: • Absolute: Applies the force directly to the particles. • Relative: Applies the force in a way that causes the particles' velocity to tend towards the Velocity value. The speed at which they do this depends on the difference between the particles' velocity and the target Velocity. This transition is faster with a higher Drag value and a lower particle mass. This option is useful to simulate a flow, like wind, that particles follow without ever exceeding the target velocity. |

Vector |
The force vector this Block applies to particles. This property only appears if you set Mode to Absolute. |
Velocity |
Vector |
The relative velocity that affected particles tend towards. This property only appears if you set Mode to Relative. |
Drag |
float |
The drag coefficient. This property only appears if you set Mode to Relative. |
This Block only affects the particle position if you enable the Update Position setting in the Update Context.
