Lua CS50游戏轨道：马里奥

我在这方面已经坚持了大约两个星期了，我仍然有动力完成这项工作，因为我已经接近课程的结尾了

我已经能够正确生成金字塔和旗帜，并确保没有蘑菇或灌木经过我的金字塔生成到关卡的末尾

然而，我似乎无法理解的部分是：

-- 10% chance to not generate anything, creating a gap
elseif math.random(10) ~= 1 then
            -- creates column of tiles going to bottom of map
            for y = self.mapHeight / 2, self.mapHeight do
                self:setTile(x, y, TILE_BRICK)
            end

            -- chance to create a block for Mario to hit
            if math.random(15) == 1 and x < self.mapWidth - 10 then
                self:setTile(x, self.mapHeight / 2 - 4, JUMP_BLOCK)
            end

            -- next vertical scan line
            x = x + 1
        else
            -- increment X so we skip two scanlines, creating a 2-tile gap
            x = x + 2
        end

——有10%的机会不产生任何结果，造成差距
其他数学。随机（10）~=1
--创建位于地图底部的一列平铺
对于y=self.mapHeight/2，self.mapHeight do
self:setTile（x，y，TILE_-BRICK）
结束
--有机会为马里奥创造一个拦网
如果math.random（15）==1且x

我将生成金字塔和标志的代码放在所有其他实体之后。然而，如果上面代码块中的条件得到满足（math.random（10）=1），我的地图的最后一部分将只是一个大缺口，金字塔和标志将全部消失

由于math.random的逻辑在创建间隙的情况下被翻转，如何防止间隙生成超过任意点（例如，x 关于生成的其余代码如下所示，没有其他更改：

-- begin generating the terrain using vertical scan lines
    local x = 1
    while x < self.mapWidth do

        -- 2% chance to generate a cloud
        -- make sure we're 2 tiles from edge at least
        if x < self.mapWidth - 2 then
            if math.random(20) == 1 then

                -- choose a random vertical spot above where blocks/pipes generate
                local cloudStart = math.random(self.mapHeight / 2 - 6)

                self:setTile(x, cloudStart, CLOUD_LEFT)
                self:setTile(x + 1, cloudStart, CLOUD_RIGHT)
            end
        end

        -- 5% chance to generate a mushroom
        if math.random(20) == 1 and x < self.mapWidth - 10 then
            -- left side of pipe
            self:setTile(x, self.mapHeight / 2 - 2, MUSHROOM_TOP)
            self:setTile(x, self.mapHeight / 2 - 1, MUSHROOM_BOTTOM)

            -- creates column of tiles going to bottom of map
            for y = self.mapHeight / 2, self.mapHeight do
                self:setTile(x, y, TILE_BRICK)
            end

            -- next vertical scan line
            x = x + 1

        -- 10% chance to generate bush, being sure to generate away from edge
        elseif math.random(10) == 1 and x < self.mapWidth - 10 then
            local bushLevel = self.mapHeight / 2 - 1

            -- place bush component and then column of bricks
            self:setTile(x, bushLevel, BUSH_LEFT)
            for y = self.mapHeight / 2, self.mapHeight do
                self:setTile(x, y, TILE_BRICK)
            end
            x = x + 1

            self:setTile(x, bushLevel, BUSH_RIGHT)
            for y = self.mapHeight / 2, self.mapHeight do
                self:setTile(x, y, TILE_BRICK)
            end
            x = x + 1

        -- 10% chance to not generate anything, creating a gap
        elseif math.random(10) ~= 1 then
            -- creates column of tiles going to bottom of map
            for y = self.mapHeight / 2, self.mapHeight do
                self:setTile(x, y, TILE_BRICK)
            end

            -- chance to create a block for Mario to hit
            if math.random(15) == 1 and x < self.mapWidth - 10 then

            x = x + 1
        else
            -- increment X so we skip two scanlines, creating a 2-tile gap
            x = x + 2
        end

         -- generate pyramid starting at least 7 blocks away from right edge
        if x == self.mapWidth - 7 then
            for j = 1, 4, 1 do
                self:setTile(x, self.mapHeight / 2 - j, TILE_BRICK)

                -- creates column of tiles going to bottom of map
                for y = self.mapHeight / 2 - (j - 1), self.mapHeight / 2 - 1 do
                    self:setTile(x, y, TILE_BRICK)
                end
                x = x + 1

                -- ensure nothing is generated between pyramid and flag
                for y = 0, self.mapHeight / 2 - 1 do
                    self:setTile(x, y, TILE_EMPTY)
                end

                for x = self.mapWidth - 7, self.mapWidth do
                    for y = self.mapHeight / 2, self.mapHeight do
                        self:setTile(x, y, TILE_BRICK)
                    end

谢谢你的帮助

这也是我一段时间以来一直在努力解决的问题。我理解这个问题的最好方法是

仅当x变量达到

self.mapWidth-7

时才会触发级别结束程序生成，因为对于x=1，self.mapWidth do级别的程序生成不是以

的形式进行的，因此每次加载贴图时都会达到
x==self.mapWidth-7

为了解决这个问题，我在Map.lua文件中，把level编码序列的末尾放在前面提到的部分之后

 -- first, fill map with empty tiles
    for y = 1, self.mapHeight do
        for x = 1, self.mapWidth do
            
            -- support for multiple sheets per tile; storing tiles as tables 
            self:setTile(x, y, TILE_EMPTY)
        end
    end

已开始在公式中进行编码，以创建与self.mapWidth末端适当距离的棱锥体和旗杆

-- create the end of level terrain 
    
    -- make local variables for ease of editing
    local PFront = self.mapWidth - 22
    local PEnd = self.mapWidth - 15
    local PTop = self.mapHeight / 2 - 1
    local PBottom = self.mapHeight / 2 - 1

    for x = PFront, PEnd, 1 do
        for y = PBottom, PTop, -1 do
            self:setTile(x, y, TILE_BRICK)
        end
        PTop = PTop - 1
    end
      
    -- Generates a uniform ground for the final section
    for x = self.mapWidth - 22, self.mapWidth do
        for y = self.mapHeight / 2, self.mapHeight do
            self:setTile(x, y, TILE_BRICK)
        end
    end

    -- Flag pole with declared top and bottom with iterated shaft
    for y = self.mapHeight / 2 - 7, self.mapHeight / 2 - 2 do
        self:setTile(self.mapWidth - 6, y, MIDDLE_POLE)
    end
    self:setTile(self.mapWidth - 6, self.mapHeight / 2 - 8, TOP_POLE)
    self:setTile(self.mapWidth - 6, self.mapHeight / 2 - 1, BOTTOM_POLE)

然后在所有这些之后继续到这段时间。。。从类代码中执行循环公式

 -- begin generating the terrain using vertical scan lines
    x = 1
    while x <= self.mapWidth - 23 do
    
    ...the rest of the Map.lua file
