Actor's Look-at Behavior

Every CrazyTalk actor can be made to track (look-at) the cursor or a specific target object by using the API command.

Note:

Please note that the paired camera must be kept to ensure the effects of the Fade in and Fade out.

Using the Example

The API Command

The syntax of the API command that has the actor start to look at something is as follows:

CTPluginAPI.SetLookAtMode (Mode, Target);

SetLookAtMode: This is the API command that causes the actor to track in different modes.
Mode: The mode for the actor to look at the cursor or a target. The modes can be GameView, FullScreen or TargetTracking.

Target: This is a GameObject in Unity. If you left it unfilled, then the actor will only look at the cursor.

Note:

You need to follow the steps below to define the target for tracking.

Create a game object with animations.
Create a script file with JavaScript or C# programming language for calling API commands.
Declare a GameObject variable in the script file (in this case, C# language is used as an example) as a target.
Drag and drop the script file onto the Main Camera.
In the camera's Inspector panel, you will find an empty field that is created by the declaration in step a.
Drag and drop the target game object into this field so that the script file is able to aware that the object is the target for tracking.

The sliders in the example determine the rolling strength of the eyeballs and the delay time for tracking when the target (cursor or game object) moves through the two API commands below:

actorAPI.SetLookAtStrength ( Value);

SetLookAtStrength: This command is used to set the rolling strength of the eyeballs when the actor looks at a target.
Value: This determines the strengthening via a float type value.

actorAPI.SetLookAtDelay (Delay Time);

SetLookAtDelay: This command is used to set the delay time for the actor to track a target.
Delay Time: This value is in float type to define the time lag, and the unit is second.
