The Dialogue module is 100% customizable and isn't restricted by any type of UI style. The Dialogue module comes with two skins that can be easily swapped between them.
A skin is a prefab that is used whenever a conversation line or choice is displayed. They are automatically managed by the Dialogue module.
To use a skin all there is to do is to drag and drop the Skin Prefab onto the Dialogue Skin field found in the preferences menu.
Additionally, each Text Element has its own unique Skin field in case you want to change the skin for a particular conversation line. Otherwise, the default skin will be used.
To create a custom Dialogue skin, we recommend duplicating the default skin prefab and modify that one. You can find the default skin at:
Default Skin pathPlugins/GameCreator/Dialogue/Resources/GameCreator/DefaultSkin.prefab
You can place the duplicated anywhere you want in your project. To modify it, drag and drop it in the scene, make whatever changes you want and don't forget to hit "Apply Changes" in the Inspector! Otherwise your prefab won't be saved.
Once you're happy with your new skin, you can safely delete it from the scene (remember to apply the changes!) and drag and drop this new prefab into the skin field in the Preferences Window Dialogue tab.
