Lua 2D数组错误

Question

所以我对Lua来说相当新，而在其他语言中，我已经能够创建一个2D变量数组，并简单地通过数组索引以创建平铺地图。每当我在lua中尝试这个时，我都会收到一个错误（特别是一个错误，表明我正在索引一个nil值）。我该如何解决这个问题？

CODE

function love.load()
love.graphics.setColor(255,255,0)
tile = love.graphics.newImage("lightGrass.png")
map = { {1,1,0,0,0,0,0,0,0,0},
        {0,1,0,0,0,0,0,0,0,0},
        {0,1,0,0,0,0,0,0,0,0},
        {1,1,0,0,0,0,0,0,0,0},
        {0,0,0,0,0,0,0,0,0,0},
        {0,0,0,0,0,0,0,0,0,0},
        {0,0,0,0,0,0,0,0,0,0},
        {0,0,0,0,0,0,0,0,0,0},
        {0,0,0,0,0,0,0,0,0,0},
        {0,0,0,0,0,0,0,0,0,0}
    }
end

function love.draw()
    for i = 0, 10 do
        for j = 0, 10 do
            newPos = map[i][j]
            if newPos == 0 then -- this is where the error is!!!!!!!!!!!!!!!
                love.graphics.draw(tile,j * 32, i * 32)
            end
        end
    end

end

function love.update(dt)

end

Answer 1

Lua中的数组从1开始，而不是从0开始。因此，for循环必须从1开始。
