centerX += speedX; r.set(centerX, centerY, 50, 50); if(Rect.intersects(r,GameScreen.soldier.r)) { System.out.println("collision"); }
我在碰撞检测方面遇到了麻烦。我已经尝试过Rect.intersects，r.intersect（r1），r.contains（r1），并且始终为false。我什至绘制矩形以确保正确绘制并且正确绘制，但是碰撞始终为假
/** * Check if two rectangles collide * x_1, y_1, width_1, and height_1 define the boundaries of the first rectangle * x_2, y_2, width_2, and height_2 define the boundaries of the second rectangle */ boolean rectangle_collision(float x_1, float y_1, float width_1, float height_1, float x_2, float y_2, float width_2, float height_2) { return !(x_1 > x_2+width_2 || x_1+width_1 < x_2 || y_1 > y_2+height_2 || y_1+height_1 < y_2); }
