Applies a force to simulate water flowing over the surface.

Inputs

NameIDDescriptionType
Apply?BIf false, the Force will not be applied to the Quelea. This is useful for having Behaviors override Forces. Can also be used for only applying the force if the Quelea is within a certain area.Boolean
Weight MultiplierWThe factor by which the force will be multiplied by.Number
Particle QueleaPQA particle is a point that can be affected by forces that do not require a perception of its surroundings or used to supply settings for an agent.Goo
EnvironmentEnThe Surface or Polysurface Environment to flow over.Goo
Step distanceDThe distance the particle will move each timestep. Smaller distances will lead to more accurate results.Number
Rotation AngleAThe angle that the surface tangent vector will be multiplied by PI and rotated by. A 0 angle will cause the particle to flow across the surface whereas a 0.5 angle will cause the particle to flow down the surface.Number

Outputs

NameIDDescriptionType
ForceFThe resulting force vector for debugging purposes.Goo
Desired VelocityDThe calcuted desired velocity of this rule before it is applied to the quelea. Supplied for debugging and visualization purposes.Goo
