issue.js鼠标单击主体 [英] matter.js mouse click on body

问题描述

您好，如果我对something.js库有类似以下的代码:

Hello if I have some code like the following for the matter.js library :

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

 // add all of the bodies to the world
 World.add(engine.world, [boxA, boxB, ground]);
Events.on(engine, 'tick', function(event) {
    if(mouseConstraint.mouse.button == 0){
            alert("what is clicked?");
        }
    });

有没有办法确定事件处理程序中是否用鼠标单击了boxA或boxB?

Is there a way I can tell if boxA or boxB has been clicked with the mouse in the event handler ?

推荐答案

mouseConstraint.body包含被单击的正文.
