Porting Godot 3: Input
Note: Homebrodot adds set and get functions for various joypad sensors in Godot 3, which is not a feature present in upstream Godot 3 at the time of writing this (but was added in Godot 4).
Implementing input is a mostly freeform system in Godot 3; most of the platform code could be doing pretty much anything, as long as it updates the InputDefault singleton. For interacting with it, there's a couple important things to note:
- Each input device (up to 16) has an id, which is an
int -
InputDefaultexpects Godot's input table values for reference of what button was just pressed.
- A function to process inputs, which should probably be run every loop within
OS:run()for your platform. - Your input system must talk to the
DefaultInputsingleton for Godot to detect inputs.
- Handling for multiple controllers (input can be handled in a singular way for platforms where only one joypad is relevant, like handhelds)
