Agent avoidance

The agents avoidance module makes sure your agents directions do not cross each other.

Attributes

Attributes	Type	Overridable	Description
method	int	no	The method to be used for the avoidance: Time To Collision (0) RVO (1) PedVO (2), optimized RVO algorithm for pedestrian simulation RVO3D (3), used for agents moving in the 3D space, such as birds, fishes, etc
distance	double	no	The threshold distance. All agents within this distance range will be evaluated.
maxTurnAngle	double	no	The max turn angle.
steeringForce	double	no	The force used for steering the agent direction. (Time To Collision only)
boundingBoxMultiplier	double	no	Bounding box multiplier. Bounding box sizes are used for predicting future collisions.
weight	double	yes	Weight
agentGroups	stringArray	no	array of agent group names. The agent groups will be considered during the evaluation.
velocityThreshold	double	no	The velocity threshold. If the agent velocity magnitude is lower than this value the agent is not evaluated
debug	bool	no	Enables module debug drawing.
editPosition	bool	no	If on, this module tries to force also the agent positions so they don't intersect with each other. (RVO only)
timeHorizon	double	no	The time used by the RVO algorithm to check for collisions with agents in the future. (RVO, PedVO and RVO3D only)
timeHorizonObstacles	double	no	The time used by the RVO algorithm to check for collisions with obstacles in the future. (RVO and PedVO only)
maxVelocity	double	no	The default maximum speed of an agent (RVO, PedVO and RVO3D only)
editPosition	bool	no	If on, the position of the agent might be affected as well as the direction. (RVO only)
distanceNeighbors	double	no	The threshold distance. All agents within this distance range will be evaluated. In RVO and PedVO will be used also for the obstacle neightbors
maxNeighbors	int	no	The maximum number of agents allowed in the neighborhood
radiusMultiplier	double	no	The radius multiplier.
strideFactor	double	no	Factor to determine the inverse stride length of an agent (1.57 is recomended). Lower values represent greater stride lengths. (PedVO only
strideBuffer	double	no	Factor to determine the sensitivity of an agent to density (0.9 is recomended). Lower values represent higher sensitivity (PedVO only)
turningBias	double	no	Factor to allow higher turning angles while navigating around obstacle corners (PedVO only)
sceneScale	double	no	The factor to convert velocities and positions into the right scale in the PedVO method, i.e., set scale to 100 if the agents size is in centimeters
steps	int	no	Number of algorithm executions per frame (RVO, PedVO and RVO3D only)
navMesh	string	no	The navigation mesh name to avoid obstacles (RVO and PedVO only)
dyamicObstaclesUpdate	bool	no	If enabled, the dynamic obstacles will be evaluated at each frame.\nIf disabled, they will be computed at init simulation only.
dynamicObstacles	meshArray	no	The array of dynamic mesh obstacles
dynamicObstaclesParentMatrix	matrixArray	no	The array of parent matrices of the dynamic obstacles
dynamicObstaclesTranslation	vector3Array	no	The array of translations of the dynamic obstacles
dynamicObstaclesScale	vector3Array	no	The array of scales of the dynamic obstacles
dynamicObstaclesRotation	vector3Array	no	The array of rotations of the dynamic obstacles
ignoreNextDirectionalModules	bool	yes	If enabled, all next directional modules in the stack will be ignored.
editLocomotionLinearVelocity	bool	yes	If on, this module will edit the targetLinearVelocity metadata used by the locomotion system.
editLocomotionAngularVelocity	bool	yes	If on, this module will edit the targetAngularVelocity metadata used by the locomotion system.
linearVelocityMin	double	yes	The minimum value for the locomotion linear velocity
linearVelocityMax	double	yes	The maximum value for the locomotion linear velocity
negativeLinearVelocityMax	double	yes	The maximum value for the locomotion linear velocity when the target is behind the agent
