将鼠标悬停在圆圈上拖动对象 - Adobe Animate/Create.js/Easel.js

Question

使用 Adobe Animate HTML5 Canvas 使用 Create.js/Easel.js.

我有以下代码，可以将对象拖成一个圆圈。

工作正常，但只有当光标在对象上时对象才可以移动；对象 streakRotatorKnob.

var knob_X = 454;
var knob_Y = 175;
var radius = 80;

root.streakRotatorKnob.addEventListener("pressmove",moveF.bind(this));

function moveF(e){ 
var rads = Math.atan2(stage.mouseY-knob_Y,stage.mouseX-knob_X);
e.currentTarget.x = knob_X + radius * Math.cos(rads);
e.currentTarget.y = knob_Y + radius * Math.sin(rads);
stage.update();
}

我尝试了以下方法，但它对 if statement 根本不起作用：

var knob_X = 454;
var knob_Y = 175;
var radius = 80;

root.streakRotatorKnob.addEventListener("pressmove",moveF.bind(this));

function moveF(e){
    if(stage.mouseY == root.streakRotatorKnob.y && stage.mouseX == root.streakRotatorKnob.x){
var rads = Math.atan2(stage.mouseY-knob_Y,stage.mouseX-knob_X);
e.currentTarget.x = knob_X + radius * Math.cos(rads);
e.currentTarget.y = knob_Y + radius * Math.sin(rads);
stage.update();
    }
}

更新

根据下面 Muhammed Maruf 的回答（Adobe Animate 版本），以下内容通过删除以下行效果更好：

root.c.addEventListener("rollout", rollout);

所以我们只有：

stage.enableMouseOver();
var knob_X = 454;
var knob_Y = 169;
var radius = 90;
var root = this;


root.c.addEventListener("rollover", rollover);
//root.c.addEventListener("rollout", rollout);

function rollover(e)
{
    console.log("rollover")
    root.c.addEventListener("pressmove", moveF);
}
function rollout(e)
{
    console.log("rollout")
    root.c.removeEventListener("pressmove", moveF);
}
function moveF(e)
{
    var rads = Math.atan2(stage.mouseY - knob_Y, stage.mouseX - knob_X);
    e.currentTarget.x = knob_X + radius * Math.cos(rads);
    e.currentTarget.y = knob_Y + radius * Math.sin(rads);
    stage.update();
}

Answer 1

这就是我编辑代码的方式。我想你是那个意思。

stage.enableMouseOver();
var knob_X = canvas.width/2;
var knob_Y = canvas.height/2;
var radius = 90;
var root = this;
root.streakRotatorKnob.addEventListener("rollover", rollover);
root.streakRotatorKnob.addEventListener("rollout", rollout);
function rollover(e)
{
    console.log("rollover")
    root.streakRotatorKnob.addEventListener("pressmove", moveF);
}
function rollout(e)
{
    console.log("rollout")
    root.streakRotatorKnob.removeEventListener("pressmove", moveF);
}
function moveF(e)
{
    var rads = Math.atan2(stage.mouseY - knob_Y, stage.mouseX - knob_X);
    e.currentTarget.x = knob_X + radius * Math.cos(rads);
    e.currentTarget.y = knob_Y + radius * Math.sin(rads);
    stage.update();
}

Answer 2

因为时差问题才看到你写的。让我回答你最后的评论如下。在我发布的示例中，我对 canvas 进行了平均。在给出起始位置时，您需要输入初始位置信息，就像旋转它一样。我还解决了 Mac 设备的问题。例子应该是：

stage.enableMouseOver();
var knob_X = canvas.width/2/stage.scaleX;
var knob_Y = canvas.height/2/stage.scaleY;
var radius = 90;
var root = this;

var rads = Math.atan2(1-knob_Y,1-knob_X);
root.streakRotatorKnob.x = knob_X + radius * Math.cos(rads);
root.streakRotatorKnob.y = knob_Y + radius * Math.sin(rads);


root.streakRotatorKnob.addEventListener("rollover", rollover);
root.streakRotatorKnob.addEventListener("rollout", rollout);
function rollover(e)
{
    console.log("rollover")
    root.streakRotatorKnob.addEventListener("pressmove", moveF);
}
function rollout(e)
{
    console.log("rollout")
    root.streakRotatorKnob.removeEventListener("pressmove", moveF);
}
function moveF(e)
{
    var rads = Math.atan2(stage.mouseY/stage.scaleY - knob_Y, stage.mouseX/stage.scaleX - knob_X);
    e.currentTarget.x = knob_X + radius * Math.cos(rads);
    e.currentTarget.y = knob_Y + radius * Math.sin(rads);
    stage.update();
}
