설명

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.

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); } }

변수

additionalShaderChannelsGet or set the mask of additional shader channels to be used when creating the Canvas mesh.
cachedSortingLayerValueCached calculated value based upon SortingLayerID.
isRootCanvasIs this the root Canvas?
normalizedSortingGridSizeThe normalized grid size that the canvas will split the renderable area into.
overridePixelPerfectAllows for nested canvases to override pixelPerfect settings inherited from parent canvases.
overrideSortingOverride the sorting of canvas.
pixelPerfectForce elements in the canvas to be aligned with pixels. Only applies with renderMode is Screen Space.
pixelRectGet the render rect for the Canvas.
planeDistanceHow far away from the camera is the Canvas generated.
referencePixelsPerUnitThe number of pixels per unit that is considered the default.
renderModeIs the Canvas in World or Overlay mode?
renderOrderThe render order in which the canvas is being emitted to the Scene. (Read Only)
rootCanvasReturns 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.
scaleFactorUsed to scale the entire canvas, while still making it fit the screen. Only applies with renderMode is Screen Space.
sortingLayerIDUnique ID of the Canvas' sorting layer.
sortingLayerNameName of the Canvas' sorting layer.
sortingOrderCanvas' order within a sorting layer.
targetDisplayFor 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].
