public Vector2[] vertices ;

설명

Returns a copy of the array containing sprite mesh vertex positions.

// Obtain the vertices from the script and modify the position of one of them. Use OverrideGeometry() for this.
//Attach this script to a Sprite GameObject
//To see the vertices changing, make sure you have your Scene tab visible while in Play mode.
//Press the "Draw Debug" Button in the Game tab during Play Mode to draw the shape. Switch back to the Scene tab to see the shape.
