POP Steer Turn Constraint dynamics node

Constrains agent velocity to only go in a direction within a certain angle range of its current heading, to prevent agents from floating backward.

Since

14.0

This node is used internally in the Crowd solver. It relies on the crowd system’s steerforce attribute, so unlike other “POP Steer” nodes it is not also useful for plain particles.

This node modifies agent/particle speed based on its orientation and target velocity direction. It will be scaled based on agent orientation/facing direction and velocity direction. Value of zero will result in speed unaffected, where at Max Angle the speed will be zero. Any values in between will be linearly scaled 0 to 1.

Parameters ¶

Activation

When this is off, the node will have no effect. You can animate this to turn the behavior on or off at different times.

Use

Custom Vector

Min Angle
