A template project to develop native games for the Powkiddy RGB30 using raylib

Raylib Game Template for Powkiddy RGB30

This is a template project for creating games with raylib on the Powkiddy RGB30 Linux arm64 handheld running JELOS using an arm64 Linux development machine. While cross-compiling is possible, it's outside the scope of this template.

Setup Linux dev environment

./setup_linux.sh

This will allow you to save your device's SSH IP and password, install dev dependencies required to compile your game for aarch64 PLATFORM_DRM using OpenGL ES 2.0. It will call initialize_rgb30 in the makefile which will access your device over ssh to create the required folder in ports and add a launch script.

NOTE: Be sure that your device is on, connected to same network as your development machine, and ssh is enabled.

Raylib dependency

Packaged with this template is raylib-5.0 compiled for PLATFORM_DRM. If you wish to run your builds on desktop during development, then you'll need to include a pre-built copy of raylib for PLATFORM_DESKTOP.

Building for RGB30

To build specifically for the RGB30, use the following command:

make rgb30

Doing so keeps the raylib makefile relatively stock to facilitate development/testing on desktop.

Sending build to device

To send the build to device over ssh, use the following command:

make send

Additional Commands

To build and send to device, use:

make rgb30 send

Custom controller implementation

• When compiled for PLATFORM_DRM, the rcore function, IsGamepadButtonPressed, doesn't return true when a button is pressed. Instead use is_button_pressed which returns a boolean on button press in conjunction with update_button_state before draw and refresh_button_state after draw. These functions emulate the raylib core implementation.

• The default value from raylib, GAMEPAD_BUTTON_UNKNOWN = 0, conflicts with the RGB30's keyinput values where RIGHT_FACE_DOWN ("B") reports as 0. The enum rgb30_buttons arranges the buttons by the keyinput value reported on the device.

Known Issues

• Does not work on Rocknix due to graphics driver changes. I have to investigate further to determine the cause.
