Desktop Screenshots for GameMaker

Quick links: documentation · GM Marketplace (if you prefer) · Unity version

This extension allows for a variety of things regarding taking screenshots of desktop - you can get a screenshot of entire desktop, or capture a part of it, or even get a screenshot of all displays on multi-monitor setups (particularly convenient if your game had been moved away from the primary screen).

Images of screen can be captured into surfaces (for drawing) and/or buffers (for storage/later recovery) - see doc for more information.

As such, this can be used for a variety of things:

• Screensavers (like the standard "Bubbles" one)
• Using a screenshot of the player's desktop as a game background
• Custom screenshot tools (there's always space for improvements)
• Timelapse recorders (ditto)
• GIF recorders (within reasonable)
• Custom accessibility tools (magnifiers, previewing a portion of a screen through a shader - see demo)
• (and so on)

New! Now includes display_measure, allowing you to precisely poll individual monitor coordinates and active areas.

Supported versions:

• display_screenshot: GMS2
  (GMS1 has an issue on some GPUs caused by a bug in Intel drivers)
• display_measure: GMS1 and GMS2

Supported platforms: Windows, Windows (YYC)
