我需要在 Matter.js 中制作这个形状:
这是我尝试过的(我从 Figma 中获取要点并将它们插入到 Matter.js 中):
const logoBottom = Matter.Bodies.fromVertices(
150,
150,
[
[
Matter.Vector.create(13.06, 22.53),
Matter.Vector.create(66.94, 22.53),
Matter.Vector.create(58.24, 37.54),
Matter.Vector.create(39.03, 37.54),
Matter.Vector.create(48.64, 54.1),
Matter.Vector.create(40, 69),
],
],
{ isStatic: true }
);
但是,侧面的凹口没有显示,我不知道为什么。
根据评论,听起来您错过了需要添加poly-decomp。
与多分解:
const engine = Matter.Engine.create();
const runner = Matter.Runner.create();
const render = Matter.Render.create({element: document.body, engine});
const logoBottom = Matter.Bodies.fromVertices(
150,
150,
[
[
Matter.Vector.create(13.06, 22.53),
Matter.Vector.create(66.94, 22.53),
Matter.Vector.create(58.24, 37.54),
Matter.Vector.create(39.03, 37.54),
Matter.Vector.create(48.64, 54.1),
Matter.Vector.create(40, 69),
],
],
{isStatic: true},
);
Matter.Composite.add(engine.world, logoBottom);
Matter.Render.run(render);
<script src="https://cdn.jsdelivr.net/npm/[email protected]/build/decomp.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/matter-js/0.20.0/matter.min.js"></script>
没有多聚分解:
const engine = Matter.Engine.create();
const runner = Matter.Runner.create();
const render = Matter.Render.create({element: document.body, engine});
const logoBottom = Matter.Bodies.fromVertices(
150,
150,
[
[
Matter.Vector.create(13.06, 22.53),
Matter.Vector.create(66.94, 22.53),
Matter.Vector.create(58.24, 37.54),
Matter.Vector.create(39.03, 37.54),
Matter.Vector.create(48.64, 54.1),
Matter.Vector.create(40, 69),
],
],
{isStatic: true},
);
Matter.Composite.add(engine.world, logoBottom);
Matter.Render.run(render);
<script src="https://cdnjs.cloudflare.com/ajax/libs/matter-js/0.20.0/matter.min.js"></script>
我不确定您使用的是哪个版本的 MJS,但这给了我以下警告:
matter-js:Bodies.fromVertices:安装“poly-decomp”库并使用 Common.setDecomp 或提供“decomp”作为全局分解凹顶点。
