}先制作一张包含所有表情的图集，导入Unity，修改图片类型和模式，然后编辑图片，切割为一个一个Sprite表情（可以使用工具自动完成，TexturePacker打包图集和TexturePacker Importer插件将打包的图集转化）
然后右键大的Sprite，创建出Sprite Asset
最后，打开TMP Settings，将创建的Sprite Asset设置为默认的表情
使用：
打开Sprite Asset，可以在SpriteCharacterTable看到一个个的表情和对应的Index
使用的时候输入<sprite=Index>就可以
function M:SetLimitByteLength(length) self.limitLength = length + 1 --不知道为啥 不加1就不正确 self:RemoveOnValidateInput() --self.unity_uitextmeshinput 为Input组件 self.__onValidateInput = handler(self,self.OnValidateInput) self.unity_uitextmeshinput.onValidateInput = self.__onValidateInput end --lua去长度为字节长度 function M:OnValidateInput(text,charIndex,c) if (#(text .. c) > self.limitLength ) then return '\0' --大于的时候返回空字符 此时会输入无效了 else return c end end function M:RemoveOnValidateInput() if self.__onValidateInput ~= nil then self.unity_uitextmeshinput.onValidateInput = nil self.__onValidateInput = nil end end
ContentSizeFitter自适应内容
Horizontal Fit和Vertical Fit如果两个都选择PreferredSize将会优先水平方向的，也就是随着内容的增加，只会修改width属性使用内容。
如果要使用水平方向的，可以固定width宽度，设置Horizontal Fit为Unconstrained、Vertical Fit为PreferredSize，当内容这一个宽度不够放时就会向下扩展修改height了。
背景和文本结构：
背景MsgImage组件（使用九宫格）：
文本MsgText组件（程序主要对这个组件进行操作）：
结构设置完效果：
程序控制适应方向：
--item.txt_msg 文本组件 --item.fitter_msg 文本的Content Size Fitter组件 --self.MaxPreferredWidth 一行文本允许的最大宽度 --self.PreferredHeight 一行文本的高度 function M:SetItemText(item,content) self:ResetItem(item) --假设水平够用 item.txt_msg:SetText(content) if(item.txt_msg:GetPreferredWidth() > self.MaxPreferredWidth) then --水平宽度超过了允许的最大宽度 item.txt_msg:SetSizeDelta(Vector2(self.MaxPreferredWidth,0)) --设定固定宽度，垂直适应 item.fitter_msg:SetFitVertical() local allTextHight = item.txt_msg:GetPreferredHeight() --获取到文本的总高度，对列表的item高度设置有用 end end function M:ResetItem(item) item.fitter_msg:SetFitHorizontal() item.txt_msg:SetSizeDelta(Vector2(0,self.PreferredHeight)) --固定一行文本高度，水平适应 end
总结：
1.对文本组件挂载ContentSizeFitter，通过PreferredWidth、PreferredHeight来获取宽高
2.如果文本的PreferredWidth超过了最大设置宽度，则使用固定宽度使用垂直适应，如果没有，使用基础高度水平适应
2.背景使用计算的方式设置宽高

首先在TextMeshPro的文字显示中标记为<link ID=内容 等下脚本获取到的>展示内容</link>
新建脚本挂载到有这个TextMeshPro组件的物体上
