}
if (move_right == true && pictureBox2.Left < 665) {
pictureBox2.Left += speed;
}
if (move_up == true && pictureBox2.Top > 0) {
pictureBox2.Top -= speed;

一种可能的解决方案(不是唯一的)是创建 3 个具有所需方向的图像版本。 然后,您可以根据需要将图片分配给图片框。
也就是说,您最好直接在 PictureBox 上绘图。 绘图允许您以任意角度旋转图像,并为您提供更大的灵活性。
理想情况下,您希望使用 2D 游戏引擎而不是手动完成所有操作。
