如何修复对象边界交叉问题？

  • 772

游戏区域设置：

function love.conf(t)
    t.window.width = 400
    t.window.height = 700

有一段主要代码：

function love.load()
    -- Left wall
    w1 = {
        m = "fill",
        x = 0,
        y = 0,
        w = 50,
        h = love.graphics.getHeight()
    }

    -- Right wall
    w2 = {
        m = "fill",
        x = love.graphics.getWidth() - 50,
        y = 0,
        w = 50,
        h = love.graphics.getHeight()
    }

    stone = {
        m = "fill",
        x = 200,
        y = 0,
        w = 80,
        h = 20,
        speed = 600
    }
end

function love.update(dt)

    if stone.y > love.graphics.getHeight() then
        stone.y = 0
        stone.x = math.random(50,300)
        stone.w = math.random(25,100)
        stone.h = math.random(10,25)
    else
        stone.y = stone.y + (dt * stone.speed)
    end

end

并且右墙的右边界有一个交集，我认为可以这样解决：

  1. 确定右侧墙壁和石质物体之间的像素差异
  2. 如果纬度（stone.w）大于1点的结果，则减去
  3. Stone.x 减去 2 分的结果
  4. 将3点的结果分配给stone.x

我想这样就不会有交集了，我是这样写的：

difference = stone.x - (love.graphics.getWidth() - 50)
if stone.w > difference then
    stone.x = stone.w - difference

如果我的想法正确的话，那么我不知道在哪里注册这张支票:-D

如有错误，请帮忙指正。...

    需要确定正确的 x 范围并从中生成随机数

            stone.w = math.random(25,100)
        stone.x = math.random(50,w2.x - stone.w)
