public void OverrideGeometry (Vector2[] vertices, ushort[] triangles);


verticesArreglo de posiciones de vértice en el espacio Sprite Rect.
trianglesArreglo de índices del triángulo sprite mesh.


Define una nueva geometría Sprite.

Vertex positions are in Sprite.rect space meaning from Rect.zero to Rect.size. Pivot offset and transformation to unit space is done automatically.

The size of the triangle array must always be a multiple of 3. The vertices connected to the triangle can be shared by simply indexing into the same vertex.

Los UV de Sprite se calculan automáticamente asignando la geometría proporcionada a la textura de Sprite.

See Also: rect.

In the script example below the polygon shown in the Sprite Editor - Polygon Resizing is used. In this case the sprite has 8 sides. The right-most vertex is moved 50 pixels into the sprite. This is the third vertex.

// Obtain the vertices from the script and modify the position
// of one of them. Use OverrideGeometry() for this.
