EmojiText in Unity3D

Untiy3D.EmojiText

EmojiText

• Extends from UnityEngine.UI.Text
• Has the same performance if no EmojiConfig attached.
• Layout handled by UnityEngine.UI.Text, only replaces UVs of generated text mesh. Thus you can use RichText to change size and color of text. (Emoji sprite wont change color. I disabled it. And you also need to set sizeFactor in EmojiConfig to 1)
• No sub GameObject needed (actually need one for attaching CanvasRenderer). Use CanvasRenderer to render emoji mesh.
• Support hyperlink click event with markdown link syntax. [ClickMe](link_to_some_place)
• Support pre-defined text by markdown predefined text syntax. `predefined text`. And predefined text replacements delegates to EmojiText.willInsertBackOnePredefinedString.
• Support escape character by input \uxxxxx directly.
• Generate your own EmojiConfig with different emojis by using AltasBaker in Emoji -> Atlas Baker (you can use altas baker for other stuff, it reports all UVs and names to AtlasBakerWizard.OnAtlasBaked)
• Works in edit mode.

Quick setup

1. Copy Unity3D.EmojiText to your own Assets folder
2. Create GameObject under Canvas
3. Attach EmojiText component to the GameObject just created
4. Drag and drop asset Unity3D.EmojiText/EmojiConfig to Config field

5. Now you have emoji text with all TwitterEmoji characters.
6. If you want to handle hyperlink (markdown syntax), just add some Href On Clicked Event
7. Check scn_demo for more details.
8. Unity3D 5.3.x has bugs in InputField with emoji charaters, plz check EmojiTouchScreenInputField.cs for details (i just copy from UnityEngine.UI and did some fix).

Create your own emoji characters

1. Create folder in your project. (like Assets/MyEmoji)
2. Copy your emoji sprites to this folder. The name of sprite should be the unicode of character. If you want to replace A with emoji sprite, just put a 41.png to MyEmoji folder

3. Add EmojiText component to a GameObject without assigning EmojiConfig, you can see Create Config button in Inspector

4. Press Create Config button, you will get a EmojiConfig.asset in Assets folder

5. Select EmojiConfig.asset. You can see

6. Click Create Atlas and in the Atlas tool box, put path to Asset/MyEmoji in path to texture field, and then press Atlas button

7. Now you will atlas texture and correct emoji config with character A
