class in UnityEngine
/
Inherits from:Behaviour
/
Implemented in:UnityEngine.UIModule
Switch to ManualElement 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.
using System.Collections; using System.Collections.Generic; using UnityEditor; using UnityEngine; using UnityEngine.UI;
// Create a Canvas that holds a Text GameObject.
public class ExampleClass : MonoBehaviour { void Start() { GameObject myGO; GameObject myText; Canvas myCanvas; Text text; RectTransform rectTransform;
// Canvas myGO = new GameObject(); myGO.name = "TestCanvas"; myGO.AddComponent<Canvas>();
myCanvas = myGO.GetComponent<Canvas>(); myCanvas.renderMode = RenderMode.ScreenSpaceOverlay; myGO.AddComponent<CanvasScaler>(); myGO.AddComponent<GraphicRaycaster>();
// Text myText = new GameObject(); myText.transform.parent = myGO.transform; myText.name = "wibble";
text = myText.AddComponent<Text>(); text.font = (Font)Resources.Load("MyFont"); text.text = "wobble"; text.fontSize = 100;
// Text position rectTransform = text.GetComponent<RectTransform>(); rectTransform.localPosition = new Vector3(0, 0, 0); rectTransform.sizeDelta = new Vector2(400, 200); } }
| additionalShaderChannels | Get or set the mask of additional shader channels to be used when creating the Canvas mesh. |
| cachedSortingLayerValue | Cached calculated value based upon SortingLayerID. |
| isRootCanvas | Is this the root Canvas? |
| normalizedSortingGridSize | The normalized grid size that the canvas will split the renderable area into. |
| overridePixelPerfect | Allows for nested canvases to override pixelPerfect settings inherited from parent canvases. |
| overrideSorting | Override the sorting of canvas. |
| pixelPerfect | Force elements in the canvas to be aligned with pixels. Only applies with renderMode is Screen Space. |
| pixelRect | Get the render rect for the Canvas. |
| planeDistance | How far away from the camera is the Canvas generated. |
| referencePixelsPerUnit | The number of pixels per unit that is considered the default. |
| renderMode | Is the Canvas in World or Overlay mode? |
| renderOrder | The render order in which the canvas is being emitted to the Scene. (Read Only) |
| rootCanvas | Returns the Canvas closest to root, by checking through each parent and returning the last canvas found. If no other canvas is found then the canvas will return itself. |
| scaleFactor | Used to scale the entire canvas, while still making it fit the screen. Only applies with renderMode is Screen Space. |
| sortingLayerID | Unique ID of the Canvas' sorting layer. |
| sortingLayerName | Name of the Canvas' sorting layer. |
| 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]. |
| ForceUpdateCanvases | Force all canvases to update their content. |
| GetDefaultCanvasMaterial | Returns the default material that can be used for rendering normal elements on the Canvas. |
| GetETC1SupportedCanvasMaterial | Gets or generates the ETC1 Material. |
| willRenderCanvases | Event that is called just before Canvas rendering happens. |
| enabled | Enabled Behaviours are Updated, disabled Behaviours are not. |
| isActiveAndEnabled | Has the Behaviour had active and enabled called? |
| gameObject | The game object this component is attached to. A component is always attached to a game object. |
| tag | The tag of this game object. |
| transform | The Transform attached to this GameObject. |
| hideFlags | Should the object be hidden, saved with the Scene or modifiable by the user? |
| name | The name of the object. |
| BroadcastMessage | Calls the method named methodName on every MonoBehaviour in this game object or any of its children. |
| CompareTag | Is this game object tagged with tag ? |
| GetComponent | Returns the component of Type type if the game object has one attached, null if it doesn't. |
| GetComponentInChildren | Returns the component of Type type in the GameObject or any of its children using depth first search. |
| GetComponentInParent | Returns the component of Type type in the GameObject or any of its parents. |
| GetComponents | Returns all components of Type type in the GameObject. |
| GetComponentsInChildren | Returns all components of Type type in the GameObject or any of its children. |
| GetComponentsInParent | Returns all components of Type type in the GameObject or any of its parents. |
| SendMessage | Calls the method named methodName on every MonoBehaviour in this game object. |
| SendMessageUpwards | Calls the method named methodName on every MonoBehaviour in this game object and on every ancestor of the behaviour. |
| GetInstanceID | Returns the instance id of the object. |
| ToString | Returns the name of the GameObject. |
| Destroy | Removes a gameobject, component or asset. |
| DestroyImmediate | Destroys the object obj immediately. You are strongly recommended to use Destroy instead. |
| DontDestroyOnLoad | Do not destroy the target Object when loading a new Scene. |
| FindObjectOfType | Returns the first active loaded object of Type type. |
| FindObjectsOfType | Returns a list of all active loaded objects of Type type. |
| Instantiate | Clones the object original and returns the clone. |
| bool | Does the object exist? |
| operator != | Compares if two objects refer to a different object. |
| operator == | Compares two object references to see if they refer to the same object. |
