在使用Fairy自带的TypingEffect之前，实现了打字效果的方法，最终放弃了这个方法，因为不能支持UBB语法，但是记录一下吧
-- 打字效果控件
TextTypeEffect = class("TextTypeEffect", nil)
TextTypeEffect.__index = nil
TextTypeEffect.Mode = {
-- 空闲中
None = 0,
-- 停止中
Stop = 1,
-- 打字中
Type = 2,
}
function TextTypeEffect:create(textNode, callBack)
local node = TextTypeEffect.new()
node:init(textNode, callBack)
return node
end
function TextTypeEffect:init(textNode, callBack)
self.textNode = textNode
self.callBack = callBack
self.mode = TextTypeEffect.Mode.None
FairyGUIMgr.addOnRemovedFromStage(self.textNode,function()
self:stopType()
end)
end
function TextTypeEffect:FormatText(content, len)
if content==nil then
return ""
end
-- 计算多字节字符数
local lengthUTF_8 = #(string.gsub(content, "[\128-\191]", ""))
if lengthUTF_8 <= len then
self:stopType()
if self.callBack then self.callBack() end
return content
else
local matchStr = "^"
for var=1, len do
matchStr = matchStr..".[\128-\191]*"
end
local str = string.match(content, matchStr)
return string.format("%s",str)
end
end
-- 开始打字
function TextTypeEffect:startType(content)
self.num = 1
self.content = content
self.mode = TextTypeEffect.Mode.Type
self.timer = OtkTimer:create(self:getInterval(),
function()
self.textNode.text = self:FormatText(content, self.num)
self.num = self.num + 1
end,
true
)
end
function TextTypeEffect:getTypeStatus()
return self.mode
end
-- 停止打字
function TextTypeEffect:stopType( ... )
if self.mode == TextTypeEffect.Mode.Stop then
return
end
if self.timer then
self.textNode.text = self.content
self.mode = TextTypeEffect.Mode.Stop
self.timer:stop()
end
end
function TextTypeEffect:setInterval(interval)
self.interval = interval
end
function TextTypeEffect:getInterval()
if self.interval then
return self.interval
else
return 100
end
end
