It's up to you to implement the actual dialogue rendering and input control but there are a few example balloons included to get you started.
You can find them in the /examples directory. If you want to try out these examples yourself, you'll need to clone the repository, not just download it.
NOTE: The first time you open this project in Godot 4 you'll need to save and then restart Godot (possibly twice) in order to try out the examples. There appears to be an issue with Godot when it initially creates the .godot cache folder.
Example scenes include:
- A portrait balloon showing character potraits and typing noises. This also shows using a low res balloon if the viewport is set to lower than 400px.
- Using a mutation to ask the player for their name.
- A Point n Click Adventure style interaction that includes voice acting in multiple languages.
- A Visual Novel style balloon with various character slots and mutations for adding/removing characters in the conversation.
- A C# Balloon that show how you might write a custom balloon in C#.
To see an example in action, open the scenes in /examples/test_scenes and run them.
If you want to run the Point n Click example in German then you will need to open Project Settings and change Internationalization/Locale/Test to be "de" (you might need to enable Advanced Settings to see this).
There is a "Create copy of example dialogue balloon..." item in the Project > Tools menu. When you click it you will be prompted to choose a directory to save the copied files into. From there, you can edit the new balloon to make it your own.
An example of what's possible in a more complicated balloon is what I have in my own game:
With a bit of fiddling, balloons can follow characters.
