The center (also called "Pivot") of a character or a prop decides the base for position, rotation and proportion change
in the Stage mode. You may use the Composer to
locate the center of any character or prop.
In Stage Mode, select a prop. You will notice that the center of the prop is inside a circle.
Click the Composer button.
Select the root sprite of the prop in the Composer Mode.
(The root sprite can be found in the Scene Manager)
Turn on the world axis by using the hotkey: Ctrl + A.
Click the Edit Pose button and drag the sprite away from the world center (where the axis coordination is).
Click the Back to Stage button.
The center of the prop is now different.
You may rotate or scale the character or prop, to see the difference.
Click the Pivot button on the Property Toolbar to show the Object Pivot panel to determine the position of the pivot for each component object of the prop.
Drag the Red Point away from its original
position. This point is the center, or the pivot, of the sprite.
Click the Back to Stage button.
The center of the sprite will now be relocated.
Select the prop, then press the hotkey K to show the Prop Key Editor on the Property Bar.
Pick the sprite and rotate it.
