Detailed Description

Defender

Defender is a side-scrolling 3D starfield shooter with a model-based ship and asteroids, animated UFO sprites, radar/HUD, controller support, an in-game MXVK console, a Matrix-rain intro, and optional SDL3_mixer audio.

Inputs

• -p <path> or --path <path> - asset root, usually handled automatically by run.pl
• -r <WxH> or --resolution <WxH> - window resolution
• -f or --fullscreen - fullscreen mode

Controls

• Enter or Space - skip the intro or restart from game over
• Z - thrust
• D - boost
• X - reverse direction
• W / Up - move up
• Down - move down
• A / S - roll left or right
• Space - fire while playing
• F3 - open or close the in-game console
• F4 - toggle the FPS counter
• F8 - toggle the CRT post-processing shader on or off
• Escape - quit

How It Works

The sample combines a 3D ship model, asteroid models, animated 3D sprites for UFOs and effects, a scrolling starfield, HUD text, and a scanner overlay. It renders game content through the normal MXVK scene path, then uses mxvk::VK_Window post-processing for the CRT effect.

The CRT effect is enabled by default in Defender. Press F8 at runtime to disable or re-enable the final full-screen shader pass.
