我已经在框架上进行了操作，我想做的是当我绘制的形状与碰撞时hitTest触发一个。我唯一的问题是，当行点击它时，我无法直接注册，它仅在下一次click事件之后注册。我遇到的另一个问题是点击框，其比符号的实际图像大很多倍。gotoAndStop(<lose frame>)touchTesthitTesttouchTest
var myshape:Shape;
myshape = new Shape();
myshape.graphics.lineStyle(5, 0xC807DE);
var alreadyDrawn:Shape;
alreadyDrawn = new Shape();
stage.addEventListener(MouseEvent.MOUSE_DOWN, activateDraw);
function activateDraw(event:MouseEvent):void
{
myshape.graphics.moveTo(mouseX,mouseY);
addChild(myshape);
stage.addEventListener(MouseEvent.MOUSE_MOVE, lineDraw);
stage.addEventListener(MouseEvent.MOUSE_UP, stopDraw);
}
function lineDraw(event:MouseEvent):void
{
myshape.graphics.lineTo(mouseX,mouseY);
checkIt();
}
function stopDraw(event:MouseEvent):void
{
alreadyDrawn.graphics.copyFrom(myshape.graphics);
stage.removeEventListener(MouseEvent.MOUSE_MOVE, lineDraw);
stage.removeEventListener(MouseEvent.MOUSE_UP, stopDraw);
}
function checkIt()
{
if (alreadyDrawn.hitTestObject(touchTest) == true)
{
trace("wall");
myshape.graphics.clear();
myshape.graphics.lineStyle(5, 0xC807DE);
alreadyDrawn.graphics.clear(); // clear this too
stopDraw(null); // stop active draw, if any
}
}
您可以先copyFrom在函数中使用method lineDraw，因为alreadyDrawn必须在测试之前将其绘制出来！
function lineDraw(event:MouseEvent):void
{
myshape.graphics.lineTo(mouseX,mouseY);
alreadyDrawn.graphics.copyFrom(myshape.graphics);
checkIt();
}
这种方法有效，但是由于hitTest认为rectangle包含，因此无法正确进行alreadyDrawn。您必须考虑point要测试的是您的mouse。
function checkIt():void
{
if (touchTest.hitTestPoint(mouseX, mouseY, true))
{
trace("wall");
}
}
