Agent avoidance

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
