以下是小弟写的一个lua+cocos2dx的脚本，请大家多多指教。里面使用的cocos2dx引擎是2.1的。

只需要将下面代码和上面3个图片贴到相应代码即可

小弟有的编译器老是编译不了为android请好心人贴一下图。

end

local label

–检测碰撞

–这里的移除方法写得不好，是直接在数组里移除，会导致移除项下一位不能遍历

–最好是写一个临时删除记录的表将要消除target的位置记录下来，当往下遍历的时候

–下一target位置减1，若遍历第二个匹配时再减1

–为避免如上问题：设计时一飞镖只能消灭一个敌人

local function CheckCash()

for index = 1 , table.getn(tblProjectlie)

do

–local t = {3,3,5,10}

–删除后自动伸缩表 local t = { 3, 5, 10, nil}

–被删的索引后那个元素永远不会被遍历到
