Tool-Assisted Speedrun mod for Iji 1.7
Please note that Iji was made by Daniel Remar, and these modified game and source files are modified by me (https://github.com/Kataiser). You can find the game at http://remar.se/daniel/iji.php and the source code at http://remar.se/daniel/resources.php (in "Source codes and resources 1"). iji_17_tas.gm81, the main source file, requires a registered Game Maker 8.1 to load and compile. Music files are not included, copy them from your copy of the game or from here.

Everything (recommended, includes documentation and kill script): Iji-TAS-mod-master.zip
Just the modded game: iji_17_tas.exe
Neither has an auto-updater, check back to https://github.com/Kataiser/Iji-TAS-mod occasionally for updates
IMPORTANT: this mod works by simulating key presses system-wide. As a result, defocusing the game window will result in the TAS not running and its inputs being sent wherever else. BE CAREFUL!
Keys: escape, enter, up, down, left, right, z, x, c, a, s, d, q, 1-9
Line syntax: - after a key presses and holds it, + releases it, and neither presses it for 1 frame. The number afterward is the time in frames until the next step is processed (1 would be the very next frame).
// anywhere in the line (preferably at the beginning) is a comment and won't be executed.
save: command: creates a savestate with the name after the colon (can include spaces). These take a frame, clear current input, and are not invalidated.
speed command: sets the framerate of the game, default is 30. Useful for slow-motion and fast-forward. This doesn't take a frame.
Backspace: restart game
Space: load a TAS file
N: pause/unpause
M: advance frame while paused (currently broken, causes desync)
L: load savestate
K: close Iji
Debug text:
> Current line, step, and frame
> Current inputs
> Frames until next step
> Target/actual FPS
As per the rules of TAS modding, only the bare minimum of changes to the game have been made to allow the reading of the inputs from a file, along with some minor changes to make creation much easier without affecting gameplay and the final playback. Note that in-game save files are currently broken, likely due to bug fixes in reading text files between Game Maker 7 and 8.1.
- Reading inputs from a chosen file, with guaranteed sync
- Saving and loading of savestates
- Pausing and frame-advancing (currently broken)
- Deterministic enemy RNG (currently not for every enemy)
- Framerate control (due to the lack of delta-time in Game Maker 8.1, this doesn't affect gameplay)
- Debug text (will be toggleable at some point)
Sorry. This is a work-in-progress mod of a complex game that I didn't make, in a fairly old engine that's already being pushed to its limits by this game. There's a to-do page over at https://github.com/Kataiser/Iji-TAS-mod/projects/1, and any reproducible bugs specific to the mod should be added to https://github.com/Kataiser/Iji-TAS-mod/issues.
