A summary of main features:
- The console is a single prefab built with the Unity GUI system. Just add the prefab to your scene and the console is ready to use.
- Customization through the Inspector. Turn the display of Unity log messages on or off, change console hotkey, size and opacity without having to edit the code.
- Autocompletion by pressing Tab
- Add console commands simply by applying one attribute to a function in your existing scripts.
- Console commands can also refer to GameObjects in your scene, such commands can be added straight from the Inspector.
- Built-in commands to save the console to a text file (or HTML file with coloring for errors). Useful to get a detailed log from your players.
- Run multiple commands like a script: you can write console commands in a file, and then run them all with one command from the console.
- An example scene is included, along with commented C# source code.
