将周围的相邻六边形更改为填充模式"line"

Question

我正在尝试制作一个基于六边形网格的游戏。我已经有一些基本原理（实施了六角形的邻居，因为图书馆没有原住民，也可以做到它，所以我可以重新涂上每个六角形），但是我似乎不能做一件事：

当我悬停在六角形上时，周围的邻居将更改为线填充模式（图片示例）（假设我的鼠标在左上角六角形上），但是我似乎无法弄清楚如何将它们重新更改为当我停止徘徊时"填充"。

这是相关的代码（负责检查我是否悬停在六角形上并与邻居打交道）：

function love.update()
    mx, my = love.mouse.getPosition()
    if hexGrid:containingHex(mx, my)~=nil then --am I hovering over a hexagon?
        local q,r=hexGrid:containingHex(mx, my).q,hexGrid:containingHex(mx, my).r -- get the position on the grid for the hexagon
        local neighbors=hexGrid:neighbors(q,r) -- get neighbors of hexagon I'm hovering over
        for dir, neighbor in pairs(neighbors) do -- loop through neighbor table
            if neighbor ~=nil and hexes.getHexagon(hexGrid:getHex(neighbor.q,neighbor.r))["fill"]=="fill" then -- does neighbor exist and is their fill mode "fill"?
                local neighborHexagon=hexGrid:getHex(neighbor.q,neighbor.r) -- get the hexagon from the grid
                local neighborData=hexes.getHexagon(neighborHexagon) -- get it's data from a seperate dictionary (stores color data and fill mode data)
                neighborData["fill"]="line" -- set fill mode to line
            end
        end 
    end
end

有几种方法可以做到这一点，但是最简单的（IMO）将在每个帧的末端重置上一个瓷砖的状态。

更新的循环看起来像这样：

-- Reference to the old tile position
local oldhexagon
function love.update()
    mx, my = love.mouse.getPosition()
    if hexGrid:containingHex(mx, my)~=nil then --am I hovering over a hexagon?
        -- Check if you were previously over a tile
        if oldhexagon then
            -- Set old hexagon's fill mode to line
        end
        -- Get rid of the reference for next frame
        oldhexagon = nil
        -- etc.
        oldhexagon = neighborData
    end
end
