Element that can be used for screen rendering.
Elements on a canvas are rendered AFTER scene rendering, either from an attached camera or using overlay mode.
#pragma strict @script RequireComponent(Canvas) @script RequireComponent(UIRenderer)
var verts : UIVertex[];
function Start () { var canvas : Canvas = GetComponent ("Canvas"); canvas.renderMode = RenderMode.Overlay; verts = new UIVertex[4]; GenerateVerts(); }
function GenerateVerts() { GenerateSquare(); var uiRenderer : UIRenderer = GetComponent ("UIRenderer") ; uiRenderer.SetVertices (verts); var mat = Material (Shader.Find ("Sprites/Default")); uiRenderer.SetMaterial (mat, null); }
function GenerateSquare() { var vert : UIVertex; vert.color = Color32 (255, 0, 0, 255); vert.uv = Vector2 (0, 0); vert.position = Vector3 (0, 0); verts[0] = vert; vert.position = Vector3 (0, 300); verts[1] = vert; vert.position = Vector3 (300, 300); verts[2] = vert; vert.position = Vector3 (300, 0); verts[3] = vert; }

| cachedSortingLayerValue | Cached calculated value based upon SortingLayerID. |
| isRootCanvas | Is this the root Canvas? |
| overridePixelPerfect | Allows for nested canvases to override pixelPerfect settings inherited from parent canvases. |

| sortingOrder | Canvas' order within a sorting layer. |
| targetDisplay | For Overlay mode, display index on which the UI canvas will appear. |
| worldCamera | Camera used for sizing the Canvas when in Screen Space - Camera. Also used as the Camera that events will be sent through for a World Space [[Canvas]. |
