table.remove在越界位置结束



所以我试图从数组中删除一个元素,但最终总是出现异常:

bad argument #1 to 'remove' (position out of bounds)

这是代码:

    -- setup players
    players = {}
    for i=0, 3 do
        local gp = InputHandler:gamepad(i)
        if(gp:isConnected()) then
            logMessage(i .. " is connected")
            players[i] = createCharacter(i, gp)
        end
    end
-- ....
-- update players
for k, player in pairs(players) do
    logMessage("player index: " .. k)
    -- if update returns false, the played lost all lives
    if (player.update(deltaTime) == false) then
        table.remove(players, k)
    end
end

我还尝试了另一个给定答案的循环(https://stackoverflow.com/a/12397571/1405318),错误相同。

local i=0
while i <= #players do
    local player = players[i]
    if (player.update(deltaTime) == false) then
        table.remove(players, i)
    else
        i = i + 1
    end
end

多亏了一条注释(现已删除),我可以修复它。Lua索引从1开始。所以我只需要将我的设置修改为:

-- setup players
players = {}
for i=0, 3 do
    local gp = InputHandler:gamepad(i)
    if(gp:isConnected()) then
        logMessage(i .. " is connected")
        players[i+1] = createCharacter(i, gp)
    end
end
