• Download in GameBanana

Setup

• Download UFO 50 Mod Loader and extract wherever.
• Install CoffeeTools from the Mod Loader.
• Navigate to where the UFO 50 save files are located, and create a folder named coffeetools.
  • Windows: %localappdata%/ufo50
  • Linux with Steam & Proton: ~/.steam/steam/steamapps/compatdata/1147860/pfx/drive_c/users/steamuser/AppData/Local/ufo50, may be slightly different if launched through protontricks instead of Steam
  • If you already created a savestate, the folder may be already there.

Playback

• play.ctas method
  • Simply place a .ctas file into the coffeetools folder, and rename it to play.ctas. It must be named play.ctas for it to play back!
  • Launch the modded game through the Mod Loader, and the TAS will play automatically.
• Drag method (v1.5+)
  • Drag a .ctas onto the game shortcut in the UFO 50 Mod Loader directory.

Cleanup

• Make sure to delete any savefile created during a playback to ensure a fresh save for future TASes.
• If the TAS doesn't need saving, you can go to Modding Settings in-game and turn off saving.

Notes

• You can press one button every frame instead of every other frame. Simply press it and frame-advance without holding it.
• There may be inconsistency between recording & playing in some edge cases, or error and crashes. Those bugs can be reported through the mod showcase channel - CoffeeTools thread in the UFO 50 Discord server.

Useful Mods

• Save to Different File: leaves vanilla save data untouched, and instead uses save1_modding.ufo (or 2 or 3) as savefile names.
• TODO: synabler is working on a mod that displays useful values for TAS-ing.
