【问题描述】:
从昨天开始,我遇到了函数和数组的问题。似乎没有声明杠杆ID之类的......
这是我的代码:
function tpp(leverID, from, to)
if item.uid == leverID and item.itemid == 1945 then
local count_players = #to
local store = {}
for i = 1, count_players do
local pid = getTopCreature(from[i]).uid
if (pid == 0 or not isPlayer(pid)) then
return doPlayerSendCancel(cid, 'You need ' .. count_players .. ' players to use this lever.')
end
store[i] = pid
end
for i = 1, count_players do
doSendMagicEffect(from[i], CONST_ME_POFF)
doTeleportThing(store[i], to[i], false)
doSendMagicEffect(to[i], CONST_ME_TELEPORT)
end
doTransformItem(item.uid, item.itemid + 1)
elseif item.uid == leverID and item.itemid == 1946 then
doTransformItem(item.uid, item.itemid -1)
end
end
function onUse(cid, item, fromPosition, itemEx, toPosition)
local pos = {
['pos_start'] = {
{['x'] = 1059, ['y'] = 1034, ['z'] = 7},
{['x'] = 1060, ['y'] = 1034, ['z'] = 7}
},
['pos_end'] = {
{['x'] = 1059, ['y'] = 1032, ['z'] = 7},
{['x'] = 1060, ['y'] = 1032, ['z'] = 7}
}
}
tpp(10150, pos['pos_start'], pos['pos_end'])
return true
end
我得到这个错误:
尝试索引全局“项目”(零值)
我是 lua 新手。有人能帮我吗?谢谢!
