Lua贪吃蛇笔记3

---9.蛇头与食物的碰撞
local function pengzhuang()
if snakeHead.col == snakeFood.col and snakeHead.row == snakeFood.row then  ---当食物与蛇头行列相等时---
snakeFood.col = math.random(0,9)    ---重置食物的位置--
snakeFood.row = math.random(0,9)
snakeFood:setPosition(snakeFood.col*60,snakeFood.row*60)
-----此时可以加分了----
-----此时可以添加碰撞音效了-----
-----此时可以添加蛇身了,代码上面已经给出-----
local node = cc.Node:create()
layer:addChild(node)
node:scheduleUpdateWithPriorityLua(pengzhuang,0)   ----执行碰撞的计划任务----


---10.死亡判定
1).撞墙(行or列超出范围)   2).撞到身体
local function Over()
for i=0,#allbody do
local nowbody = allbody[i]
if snakeHead.col < 0 or snakeHead.col > 9 or snakeHead.row < 0 or snakeHead.row > 9 then
self.GameOver()   ---GameOver()为另外封装的场景,可根据自身喜好编写，死亡时可直接跳转到它---
end


for i=1,#allbody do
local nowbody = allbody[i]
if snakeHead.col == nowbody.col and snakeHead.row == nowbody.row then  ---蛇头与蛇身碰撞--
self:GameOver()
end
end
end
end
local node3 = cc.Node:create()
layer:addChild(node3)
node3:scheduleUpdateWithpriorityLua(Over,0)
