Chat Client in Unity


In a chat client like msn or skype we can add emoticons which are inline images in the text. Can we have such a functionality using Unity GUI classes ? If not how do we attain it using lower level APIs ?


I assume you’ve seen the chat systems available in the Asset store (a good place to start). A quick and dirty way would be to embed them in the font texture, then detect and convert the text emoticon like :wink: to the character code for that symbol in the font texture.
To get fancier, like animated ones, you could either have multiple such characters that you cycle through, or get down-and-dirty with the API to use DrawGUITexture where needed. For that you would need precise font metrics. See GUIStyle.CalcSize and related functions.
