我是物理引擎的新手,但要开始我设想的项目,我需要让六边形在页面中心的固定位置连续旋转。
我想我从根本上误解了物理引擎的工作原理,但是当我调用 Matter.Body.rotate(hexagon, 1); 它只是在由提供的参数 (1) 渲染时立即旋转六边形,并且不会旋转得更远。我怎样才能让它连续旋转?
这是我的代码:
请注意,已设置 setStatic,因此六边形不会掉出框架。
// module aliases
var Engine = Matter.Engine,
Render = Matter.Render,
World = Matter.World,
Bodies = Matter.Bodies;
Composites = Matter.Composites;
// create an engine
var engine = Engine.create();
// create a renderer
var render = Render.create({
element: document.body,
engine: engine
});
var hexagon = Bodies.polygon(375, 300, 6, 200, {inertia: Infinity}); // setting inertia to inifinty will prevent rotation upon collision
Matter.Body.setStatic(hexagon, true);
Matter.Body.rotate(hexagon, 1);
console.log(hexagon);
// Matter.Body.rotate(hexagon, 1)
// add all of the bodies to the world
World.add(engine.world, [hexagon]);
// run the engine
Engine.run(engine);
// run the renderer
Render.run(render);
