  • c# Winform 缓动动画

    一、定义缓动动画类

    public
    class AnimationHelper { Timer animationTimer = new Timer(); double velocity = 0.0; Point location = Point.Empty; double force = 0.01; //0.69; double drag = 0.8; private Control control; //private AxShockwaveFlash control; private int targetPos=0; public AnimationHelper(int interval=5) { animationTimer.Interval = interval; animationTimer.Tick += delegate { if (control == null) return; int currentPos = control.Location.X; if (Math.Abs(currentPos - targetPos) <= 5) { control.Location = new Point(targetPos, control.Location.Y); animationTimer.Stop(); } int dx = targetPos - currentPos; velocity += force * dx; velocity *= drag; if (Math.Abs(velocity) < 5) { if (velocity > 0) velocity = 5; else velocity = -5; } control.Location = new Point(currentPos + (int)velocity, control.Location.Y); }; animationTimer.Start(); } public void MoveXEx(Control control, int targetPos, Action completeWith = null) { this.control = control; this.targetPos = targetPos; velocity = 0; animationTimer.Start(); } }

    二、’使用教程:

            AnimationHelper animationHelper = new AnimationHelper();
            AnimationHelper animationHelper1 = new AnimationHelper();
            private int pos = 0;
            private int pos1 = 0;
            private int dx = 200;
            private void button1_Click(object sender, EventArgs e)
            {
                animationHelper.MoveXEx(pictureBox2, pos += dx);
                animationHelper1.MoveXEx(pictureBox1, pos1 += dx);
               
            }
    
            private void button2_Click(object sender, EventArgs e)
            {
                animationHelper.MoveXEx(pictureBox2, pos -= dx);           
                animationHelper1.MoveXEx(pictureBox1, pos1 -= dx);
            }
