平铺精灵
¥Tiling Sprite
TilingSprite
是一种高性能方法,用于在矩形区域内渲染重复纹理。它不会拉伸纹理,而是重复(平铺)纹理以填充给定空间,这使其成为背景、视差效果、地形和 UI 面板的理想选择。
¥A TilingSprite
is a high-performance way to render a repeating texture across a rectangular area. Instead of stretching the texture, it repeats (tiles) it to fill the given space, making it ideal for backgrounds, parallax effects, terrain, and UI panels.
import { TilingSprite, Texture } from 'pixi.js';
const tilingSprite = new TilingSprite({
texture: Texture.from('assets/tile.png'),
width: 400,
height: 300,
});
app.stage.addChild(tilingSprite);
什么是 TilingSprite?
¥What is a TilingSprite?
-
它在定义的区域内重复绘制纹理。
¥It draws a texture repeatedly across a defined area.
-
除非你调整
tileScale
,否则纹理默认不会缩放。¥The texture is not scaled by default unless you adjust
tileScale
. -
精灵的整体
width
和height
决定了图块填充的区域大小,与纹理的原始大小无关。¥The sprite's overall
width
andheight
determine how much area the tiles fill, independent of the texture's native size. -
图案的偏移、缩放和旋转可以独立于对象的变换进行控制。
¥The pattern's offset, scale, and rotation can be controlled independently of the object's transform.
主要属性
¥Key Properties
属性 | 描述 |
---|---|
texture | 正在重复的纹理 |
tilePosition | ObservablePoint 控制平铺图案的偏移量 |
tileScale | ObservablePoint 控制每个平铺图的缩放比例 |
tileRotation | 控制图块图案旋转的数字 |
width / height | 图块填充区域的大小 |
anchor | 调整 TilingSprite 的原点 |
applyAnchorToTexture | 如果 true 为 ,则锚点会影响平铺图案的起始点。 |
clampMargin | 调整边距以避免边缘伪影(默认值:0.5 ) |
宽度和高度 vs 缩放比例
¥Width & Height vs Scale
与 Sprite
不同,在 TilingSprite
中设置 width
和 height
会直接更改可见的平铺区域。它不会影响图块的比例。
¥Unlike Sprite
, setting width
and height
in a TilingSprite
directly changes the visible tiling area. It does not affect the scale of the tiles.
// Makes the tiling area bigger
tilingSprite.width = 800;
tilingSprite.height = 600;
// Keeps tiles the same size, just tiles more of them
要缩放图块图案本身,请使用 tileScale
:
¥To scale the tile pattern itself, use tileScale
:
// Makes each tile appear larger
tilingSprite.tileScale.set(2, 2);
锚点和 applyAnchorToTexture
¥Anchor and applyAnchorToTexture
-
anchor
设置用于定位 TilingSprite 的枢轴/原点。¥
anchor
sets the pivot/origin point for positioning the TilingSprite. -
如果
applyAnchorToTexture
为true
,则锚点还会影响平铺图案的起始位置。¥If
applyAnchorToTexture
istrue
, the anchor also affects where the tile pattern begins. -
默认情况下,无论锚点如何,图块图案都从本地空间的 (0, 0) 处开始。
¥By default, the tile pattern starts at (0, 0) in local space regardless of anchor.
