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.
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.
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).
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.
