Look At

A CrowdBeLookAt is a Behavior which can be used to make Entities look at a given target.
 
A look at behavior in the behavior editor
 

Creating a Look At Behavior can be performed through the following options:

  • Behavior Editor / Behavior Library: 
  • Crowd Menu: Crowd Behaviors / Behaviors / CrowdBeLookAt Node
  • MEL command: glmCrowdBeLookAtCmd;

 

Configuration

A Look At Behavior defines the following specific attributes. To get more information about shared parameters, see here
 

LookAt Attributes

Look At attributes of a look at behavior
 
 
In Locator Name of the locator to look at. Notice that, this locator can be animated
Target Mode This attribute allows a choice of two target mode :
  • Absolute: The locator position will be use a target for the IK look at constraint.

  • Relative: The locator direction, determined by the direction of the locator from the center of the scene, will be use a target for the IK look at constraint.

Starting Duration / Stopping Duration (in seconds) Time used to start/stop the animation. It ensures smooth transition when starting/stopping the lookAt. These duration can be viewed as a time during which a multiplier weight is applied to priority: from 0 to 1 for starting (from inactive to fully active lookAt), from 1 to 0 for stopping (from active to inactive lookAt)

Advanced LookAt Attributes

Max Speed (in °/sec) maximum speed to reach the target
Head Percent Part of the complete adaptation which is made by the head
Neck Percent Part of the complete adaptation which is made by the neck
Bust Percent Part of the complete adaptation which is made by the bust
