所以我正在创建一个非常简单的平台游戏，我希望平台随机生成，以便每个游戏都是独一无二的。但是，我不确定如何完美地做到这一点。我设法获得了一些实际在屏幕上生成随机矩形的工作代码，但我不确定如何制作它，以便“角色”可以在它们上移动并且不会掉落等等。这是我迄今为止所有内容的代码。现在它一点也不漂亮，但当我知道一切正常时我会整理它。预先感谢您的帮助:)
附注我还注释掉了与随机矩形相关的内容，因为它们完全填满了屏幕，我看不到发生了什么:P

随机矩形.java
public class RandomRects {
private int posX1;
private int posY1;
private int posX2;
private int posY2;
private Color rectColor;
public RandomRects(int posX1, int posX2, int posY1, int posY2, Color color){
this.posX1 = posX1;
this.posX2 = posX2;

this.rectColor = color;
}
public void draw (Graphics g){
g.setColor(rectColor);
g.fillRect(posX1,posY1,posX2,posY2);
}
}
最佳答案
基本上，你需要的是“想象”移动角色；如果移动的角色与任何矩形重叠(“碰撞检测”)，请阻止移动。如果不是，则确认该字符的下一个位置是移动后的位置。您可以使用矩形方法intersects() .
