问题描述

我已经创建了一个圆圈的路径,并将它们都显示在屏幕上,如下所示:

I ave created a path a circle and displayed both of them on screen as follows:

public void onDraw(Canvas canvas){

        Path sPath = new Path();
        sPath.moveTo(100, 100);
        sPath.lineTo(300, 100);
        sPath.lineTo(300, 300);
        sPath.lineTo(100,300);
        sPath.lineTo(100,100);
        sPath.close();

        Paint ballPaint = new Paint();
        ballPaint.setColor(Color.GREEN);
        Paint pathPaint = new Paint();
        pathPaint.setColor(Color.BLUE);

        canvas.drawPath(sPath, ballPaint);
        canvas.drawCircle(100,100,20,pathPaint);
    }

我想让圆圈沿着路径移动,我该怎么做?

i would like to have the circle move along the path, how can i do this?

推荐答案

你需要将你的圆圈每帧移动一点点朝向下一个航路点,并在它到达那里时进行检测,然后开始向下一个航路点移动.据我所知,没有内置系统.

You would need to move your circle a little bit each frame towards the next waypoint and detect once it gets there, then start moving toward the next. There is no built in system that I know of.
