文字漂浮的小功能 lua代码框架下实现

功能：事件出发，向上飘出文本或者图片或者两个都有，渐隐消失

虽然是框架下实现的，不过基本逻辑都可以用。

写得不好，先留着。

viewr类的方法，具体实现功能

local this = {}

local ctrl = nil

local stringList = {}

this.gameObject = nil

function this.Init(_ctrl)

ctrl = _ctrl

this.gameObject = lua_function.LoadInstanceGameObject("popMessage")

this._endPos = lua_function.GetChild (this.gameObject,"endPos"):GetComponent("Transform")

end

--飘窗的动画控制

function this.animationController(_gameObject,_data)

if _gameObject == nil then

return

end

coroutine.start(function()

lua_function.MoveToWorld(_gameObject, _gameObject.transform.position.x, (_gameObject.transform.position.y + 300), _gameObject.transform.position.z,1.5, nil)

coroutine.wait(1)

lua_function.ChangeAlpha(_gameObject, 0, 0.5, nil)

coroutine.wait(0.5)

lua_function.Destroied(_gameObject)

-- remove掉stringList中储存的message

for k , v inpairs(stringList) do

if v == _data["msg"]then

table.remove(stringList, k)

end

end

end)

end

--参数

--messageType = 1 or 2 1纯文本 2带图片

--mas = "string"

--color = { r = 0, g = 0, b = 0}

--ima = "path"

function this.Draw(_data)

--判断没有消失的message里面有没有重复的，如果有重复的返回false，没有true

if isEnable(_data) ==false then

return

end

--根据messageType分类

if _data["messageType"] ==1 then

this.message_gameObject = lua_function.LoadInstanceGameObject("message")

lua_function.SetParent(this.message_gameObject, this.gameObject)

lua_function.SetLocalPosition(this.message_gameObject,0,0,0)

local _message_tex = this.message_gameObject:GetComponent("Text")

_message_tex.text = _data["msg"]

--默认颜色为白色

if _data["color"] ==nil then

_data["color"] = {r = 1, g = 1, b = 1, a = 1}

end

lua_function.SetColor(_message_tex.gameObject, _data["color"]["r"], _data["color"]["g"], _data["color"]["b"], _data["color"]["a"])

elseif _data["messageType"] ==2 then

this.message_gameObject = lua_function.LoadInstanceGameObject("messageAndImage")

--图片的情况可能没有msg，先判断,如果有，把字符串处理了

if _data["msg"] ~=nil then

lua_function.SetParent(this.message_gameObject, this.gameObject)

lua_function.SetLocalPosition(this.message_gameObject,0,0,0)

local _message_tex = this.message_gameObject:GetComponent("Text")

_message_tex.text = _data["msg"]

--默认颜色为白色

if _data["color"] ==nil then

_data["color"] = {r = 1, g = 1, b = 1, a = 1}

end

lua_function.SetColor(_message_tex.gameObject, _data["color"]["r"], _data["color"]["g"], _data["color"]["b"],1)

end

--type == 2 肯定有image 。处理图片，先加载图片图像，再根据字符串长短确定图片位置

local _image = lua_function.GetChild (this.message_gameObject,"image")

--确定位置

if _data["msg"] ==nil then

lua_function.SetLocalPosition(_image,0,0,0)

elseif #_data["msg"] <=12 then

lua_function.SetLocalPosition(_image,-70,0,0)--pos1的位置

elseif #_data["msg"] <=21 then

lua_function.SetLocalPosition(_image,-120,0,0)--pos2的位置

elseif #_data["msg"] <=33 then

lua_function.SetLocalPosition(_image,-160,0,0)--pos3的位置

end

--加载图片

lua_function.SetSprite (_image, _data["image"],true)

end

this.animationController(this.message_gameObject, _data)

end

--判断没有消失的message里面有没有重复的，如果有重复的返回false，没有true

function isEnable(_data)

for _ , v inpairs(stringList) do

if v == _data["msg"]then

return false

end

end

table.insert(stringList, _data["msg"])

return true

end

function this.Dispose()

end

return this

controller类的方法， 对外接口等

local this = {}

this.view = nil

this.isInit = false

function Init()

this.view = lua_manager.GetLua(lua_files.popMessage_view)

this.view.Init(this)

lua_event_listener.AddOnUIButtonClickListener("popMessage_controller", this)

isInit = true

end

--测试用

function this.Refresh()

if not isInit then

Init()

end

end

function InitTest()

if isInit then

return

end

Init()

end

--通用接口

function this.Text(_msg)

InitTest()

local x = {msg = _msg, messageType = 1}

this.view.Draw(x)

end

function this.TextWithColor(_msg,_color)

InitTest()

local x = {msg = _msg, color = _color, messageType =1}

this.view.Draw(x)

end

function this.Image(_image)

InitTest()

local x = {image = _image ,messageType = 2}

this.view.Draw(x)

end

function this.ImageWithText(_image,_msg)

InitTest()

local x = {msg = _msg, image = _image, messageType =2}

this.view.Draw(x)

end

function this.ImageWithTextWithColor(_image,_msg, _color)

InitTest()

local x = {msg = _msg, color = _color, image = _image, messageType =2}

this.view.Draw(x)

end

function this.getdefult(_type)

if _type == 1then

return "commonicon012"

elseif _type == 2 then

return "commonicon014"

elseif _type == 3 then

return "adven018"

end

end

--金币钻石经验特殊处理

function this.ShowCoin(_coin)

local _coinRes = this.getdefult(1)

this.ImageWithText(_coinRes, _coin)

end

function this.ShowCoinWithColor(_coin,_color)

local _coinRes = this.getdefult(1)

this.ImageWithTextWithColor(_coinRes, _coin, _color)

end

function this.ShowDiamond(_coin)

local _coinRes = this.getdefult(2)

this.ImageWithText(_coinRes, _coin)

end

function this.ShowDiamondWithColor(_coin,_color)

local _coinRes = this.getdefult(2)

this.ImageWithTextWithColor(_coinRes, _coin, _color)

end

function this.ShowExp(_coin)

local _coinRes = this.getdefult(3)

this.ImageWithText(_coinRes, _coin)

end

function this.ShowExpWithColor(_coin,_color)

local _coinRes = this.getdefult(3)

this.ImageWithTextWithColor(_coinRes, _coin, _color)

end

--测试的按钮

function this.OnClick(_func,_go)

if _func == "111"then

color = {r = 1, g = 1, b = 0, a = 1}

this.ShowDiamondWithColor("11111111111111", color)

elseif _func == "222" then

local y = {msg = "2222222" , color = { r = 0, g = 0, b = 1, a = 1}, messageType = 1}

this.view.Draw(y)

end

end

function this.Dispose()

this.view.Dispose()

lua_event_listener.RemoveOnUIButtonClickListener("popWindow_controller")

end

return this
