为什么这个BJ函数需要加这个判断?

elik720

function AdjustPlayerStateBJ takes integer delta, player whichPlayer, playerstate whichPlayerState returns nothing
    // If the change was positive, apply the difference to the player's
    // gathered resources property as well.
    if (delta > 0) then
        if (whichPlayerState == PLAYER_STATE_RESOURCE_GOLD) then
            call AdjustPlayerStateSimpleBJ(whichPlayer, PLAYER_STATE_GOLD_GATHERED, delta)
        elseif (whichPlayerState == PLAYER_STATE_RESOURCE_LUMBER) then
            call AdjustPlayerStateSimpleBJ(whichPlayer, PLAYER_STATE_LUMBER_GATHERED, delta)
        endif
    endif
    call AdjustPlayerStateSimpleBJ(whichPlayer, whichPlayerState, delta)
endfunction

乍一看 貌似 只有call AdjustPlayerStateSimpleBJ(whichPlayer, whichPlayerState, delta)
也可以的

求解 为什么要加上面的判断

zhuzeitou

if (whichPlayerState == PLAYER_STATE_RESOURCE_GOLD) then
            call AdjustPlayerStateSimpleBJ(whichPlayer, PLAYER_STATE_GOLD_GATHERED, delta)

PLAYER_STATE_RESOURCE_GOLD和PLAYER_STATE_GOLD_GATHERED不一样哦
也就是说对于金钱和木材，只有正值起效吧

不对啊  可是  他判断语句 里面   运行的  和  判断语句外面运行的 都是同1个函数啊  0.0
本来我也以为是只有正值起效  所以我 另delta为负数   结果  金钱还是减少了

PLAYER_STATE_GOLD_GATHERED是用于计分屏的吧？
