Running Pong with Godot on QNX

Pong with Godot on QNX

What you will learn:

How to clone a Godot project for QNX.
How to install the Godot templates on a QNX target.
How to launch a Godot game using the command line.

Prerequisites:

A host machine (Linux, macOS, or Windows) with git installed.
A target running QNX Developer Desktop (QEMU VM, Raspberry Pi 4, or Raspberry Pi 5).
Network connectivity between the host and the target.

Because this specific project is set up for cross-compilation environments, we will first clone it on your development host and then package it for the target.

Clone the repository:

git clone https://github.com/yulee-qnx/pong-qdd/

Zip the project: Navigate to the directory and compress the folder to make transferring it easier.
```
zip -r pong-qdd.zip pong-qdd
```

You need to move the project file from your host to the QNX Developer Desktop.

Find your Target IP: On your QNX terminal, run:
```
ifconfig
```
Secure Copy (SCP) the file: From your host machine, run (replace the IP with your target's actual IP):
```
scp pong-qdd.zip qnxuser@192.168.122.242:/data/home/qnxuser
```
Unzip on the Target: Switch back to your QNX target terminal and run:
```
unzip pong-qdd.zip
```

The Godot engine is available via the QNX Open Source Ports. Ensure your target has internet access to fetch the packages.

Search for available templates:
```
sudo apk search godot-templates
```
Install the templates:
```
sudo apk add godot-templates
```

Now that the engine is installed and the project files are present, you can launch the game using the rendering driver compatible with QNX Screen.

Run the Godot binary: From the QNX terminal, execute:

godot-template-release --path pong-qdd --rendering-driver opengl3_es

Game Controls

Player 1: W (Up), S (Down)
Player 2: Up Arrow (Up), Down Arrow (Down)
Exit: ESC (Initiates a proper shutdown sequence)

When developing with Godot on QNX, keep the following in mind:

Feature	Support Level	Note
Windowing	QNX Screen	Wayland is not currently supported for this port.
2D Graphics	High	Excellent for HMI and UI visualizations.
3D Graphics	Basic	Optimized assets required; avoid heavy GPU effects.
Audio	Functional	Best supported on Raspberry Pi 4/5 environments.

You have successfully deployed a Godot game to QNX! This workflow opens the door for high-quality graphical interfaces and visualizations on a hard real-time operating system.

Next Steps:

Explore the source code in the pong-qdd folder.
Try modifying the physics logic and re-running the game on your target.
