铁锹 3D打印店铺

1. 注册侦听器


Java代码  


    addEventListener(Event.ENTER_FRAME, onEnterFrame);   
    stage.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown);   
    stage.addEventListener(MouseEvent.MOUSE_UP, onMouseUp);  



addEventListener(Event.ENTER_FRAME, onEnterFrame);
stage.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown);
stage.addEventListener(MouseEvent.MOUSE_UP, onMouseUp);

2. MouseDown触发函数


Java代码



// 保存鼠标点击的摄像机参数和鼠标坐标信息   


    private function onMouseDown(event:MouseEvent):void  
    {   
        lastPanAngle = camera.panAngle;   
        lastTiltAngle = camera.tiltAngle;   
        lastMouseX = stage.mouseX;   
        lastMouseY = stage.mouseY;   
        move = ***e;   
        stage.addEventListener(Event.MOUSE_LEAVE, onStageMouseLeave);   
    }  



// 保存鼠标点击的摄像机参数和鼠标坐标信息
private function onMouseDown(event:MouseEvent):void
{
    lastPanAngle = camera.panAngle;
    lastTiltAngle = camera.tiltAngle;
    lastMouseX = stage.mouseX;
    lastMouseY = stage.mouseY;
        move = ***e;
        stage.addEventListener(Event.MOUSE_LEAVE, onStageMouseLeave);
}

3. MouseUp触发函数


Java代码


    private function onMouseUp(event:MouseEvent):void  
    {   
        move = false;   
        stage.removeEventListener(Event.MOUSE_LEAVE, onStageMouseLeave);        
    }  



private function onMouseUp(event:MouseEvent):void
{
        move = false;
        stage.removeEventListener(Event.MOUSE_LEAVE, onStageMouseLeave);     
}

4. 每帧都调用的onEnterFrame


Java代码


    private function onEnterFrame(event:Event):void  
    {   
        if (move) {   
            camera.panAngle = 0.3*(stage.mouseX - lastMouseX) + lastPanAngle;   
            camera.tiltAngle = 0.3*(stage.mouseY - lastMouseY) + lastTiltAngle;   
        }   
           
        camera.hover();   
        view.render();   
    }  



private function onEnterFrame(event:Event):void
{
        if (move) {
                camera.panAngle = 0.3*(stage.mouseX - lastMouseX) + lastPanAngle;
                camera.tiltAngle = 0.3*(stage.mouseY - lastMouseY) + lastTiltAngle;
        }
       
        camera.hover();
        view.render();
}
