The Text Tracking behavior applies a rate of change to the Tracking parameter of the Format pane (in the Text Inspector). Tracking applies a uniform space between each character of text, resulting in an expansion effect, with text characters expanding apart.
Apply the Text Tracking behavior (from the Text Animation behavior category) to text in your project.
For more information, see Apply a text behavior.
When you play the project, characters spread out based on the rate set in the Rate parameter in the Behaviors Inspector or HUD.
Note: Like the Tracking parameter in the Format pane of the Text Inspector, the Text Tracking behavior respects the Alignment setting of the text. For example, to track from the center of the text outward, the Alignment of the text must be set to Center. This parameter is located in the Text HUD or the Layout pane of the Text Inspector.
Use Text Tracking controls to modify the rate and end offset of character tracking. The identical Text Tracking behavior parameters appear in the Text Tracking HUD and in the Behaviors Inspector. See Text Tracking controls.
