Minimal Matter.js 示例：Engine.run 不是函数

如何解决Minimal Matter.js 示例：Engine.run 不是函数

我直接从 Matter.js 库的 getting started section 复制了代码，但发生了 未捕获的类型错误：“Engine.run 不是函数”。我在网上到处搜索，但没有任何帮助。作为预防措施，我添加了一个事件侦听器，以便在加载完所有内容后运行代码。

            // create an engine

            // create a renderer
            var render = Render.create({
                element: document.body,engine: engine
            });

            // create two Boxes and a ground
            var BoxA = Bodies.rectangle(400,200,80,80);
            var BoxB = Bodies.rectangle(450,50,80);
            var ground = Bodies.rectangle(400,610,810,60,{ isstatic: true });

            // add all of the bodies to the world
            Composite.add(engine.world,[BoxA,BoxB,ground]);

            // run the engine
            Engine.run(engine);

            // run the renderer
            Render.run(render);
        }

请问，我做错了什么？

解决方法

您使用了错误版本的 matter-js 库，请尝试使用最新版本。我刚刚尝试了 0.15.0，效果很好。

matter-js >= 0.10.0 支持 Render.run()。请确保您使用的支持功能的版本。

window.addEventListener("load",init);

        function init() {
            // module aliases
            var Engine = Matter.Engine,Render = Matter.Render,Runner = Matter.Runner,Bodies = Matter.Bodies,Composite = Matter.Composite;

            // create an engine
            var engine = Engine.create();

            // create a renderer
            var render = Render.create({
                element: document.body,engine: engine
            });

            // create two boxes and a ground
            var boxA = Bodies.rectangle(400,200,80,80);
            var boxB = Bodies.rectangle(450,50,80);
            var ground = Bodies.rectangle(400,610,810,60,{ isStatic: true });

            // add all of the bodies to the world
            Composite.add(engine.world,[boxA,boxB,ground]);

            // run the engine
            Runner.run(engine);

            // run the renderer
            Render.run(render);
        }
