Graphic

Description

Base class for all visual UI Component.

When creating visual UI components you should inherit from this class. Below is a simple example that draws a colored quad inside the Rect Transform area.

#pragma strict
@ExecuteInEditMode
public class SimpleImage extends Graphic {
	protected override function OnPopulateMesh(vh: VertexHelper) {
		var corner1: Vector2 = Vector2.zero;
		var corner2: Vector2 = Vector2.zero;
		corner1.x = 0f;
		corner1.y = 0f;
		corner2.x = 1f;
		corner2.y = 1f;
		corner1.x -= rectTransform.pivot.x;
		corner1.y -= rectTransform.pivot.y;
		corner2.x -= rectTransform.pivot.x;
		corner2.y -= rectTransform.pivot.y;
		corner1.x *= rectTransform.rect.width;
		corner1.y *= rectTransform.rect.height;
		corner2.x *= rectTransform.rect.width;
		corner2.y *= rectTransform.rect.height;
		vh.Clear();
		var vert: UIVertex = UIVertex.simpleVert;
		vert.position = new Vector2(corner1.x, corner1.y);
		vert.color = color;
		vh.AddVert(vert);
		vert.position = new Vector2(corner1.x, corner2.y);
		vert.color = color;
		vh.AddVert(vert);
		vert.position = new Vector2(corner2.x, corner2.y);
		vert.color = color;
		vh.AddVert(vert);
		vert.position = new Vector2(corner2.x, corner1.y);
		vert.color = color;
		vh.AddVert(vert);
		vh.AddTriangle(0, 1, 2);
		vh.AddTriangle(2, 3, 0);
	}
}
