TASmod

Tool-Assisted Speedrun Mod for Minecraft. Records inputs and plays them back.

Only for 1.12.2 at the moment, 1.16.1 version will follow eventually. More information: Future of Mineraft TAS tools

Features

• Recording and playing back inputs
• Slowing down the game / Slowmotion
• Frame Advance, but with Minecraft ticks (Tickadvance)
• Savestates
• RNG manipulation

Gui

In the bottom left of the screen are 2 UI elements:

• The number represents the input index. When recording, it shows how many ticks where recorded, when playing back, show the current index of the input being fed to the game.
• A keystroke display: White keys are the keys recognized by Minecraft, green are the keys you are pressing on your keyboard. A difference can be seen when playing in lower tickrates

Commands

-/record To start a recording. This records the inputs to RAM. The number should now increase because it detects the inputs.
-/clearinputs: Clears the currently stored inputs. Do this before starting a new recording, since /record only adds inputs and does not clear them.
-/play: Plays back the stored inputs. Before that, it teleports you to the location where you started recording.
WARNING Unfortunately the vanilla teleporting takes some time, so the player won't be able to move in the first few ticks, which oftentimes desyncs the TAS immediately. So record like 7 ticks at the start where you not move to account for that. Will be fixed sometime in the future…
/saveTAS filename: Stores the current inputs under the given filename in .minecraft/saves/tasfiles.
/loadTAS filename: Replaces the current inputs with the inputs from the file with the given filename.
/folder savestate|tasfiles Opens the savestate or tasfile folder on your disk
/savestate <save|load|delete> <index> Saves, loads or deletes the savestate under the specified index. You can find more infos ingame by using /savestates.

Hotkeys

F8 Toggles between tickrate 0 and other tickrates. Pauses the game on both client and server side.
F9 You can advance one tick at a time while you are in tickrate 0.
J Makes a savestate under .minecraft/saves/savestates. If you are recording, a savestate of the recording will be made under .minecraft/saves/tasfiles/savestates
K Loads the savestate. It will also work during recording or playback.
F6 Customize the HUD. Leftclick and drag to change the position, Rightclick to add a background
F10 Aborts a playback

Known issues

• In low tickrates / tickrate 0 you have to hold the key until the next tick so that the game recognises it. This feels awkward to use.
• No Gui: Everything is handled via commands at the moment, but a gui is planned.

TASmod

This mod is still in development major issues may arise! Planned to support 1.8.9-1.16+ eventually, but for now it only works for 1.12.2 (Mojang changed how gui screens, like the inventory are handled, the current mod would break in 1.14+)

Info

You might have seen videos, where a robot plays Super Mario Bros by sending controller signals to the console. These videos are called Tool-Assisted Speedruns and are trying to achieve the fastest time possible in the game without modifying the game files... This mod tries to bring TASing to minecraft...

Warning

This is not a client mod, joining a server where the mod is not installed will disconnect you from the server after a short amount of time...

Features

Recording and playing back inputs Slowing down the game / Slowmotion Stop the tickrate and advance one tick (Frame advance, but with ticks, so tickadvance?) Savestates RNG manipulation In the bottom left of your screen are several things. Probably the number 0 and the inputs you are pressing. The white buttons are what the game currently recognises, the green buttons are what you press on the keyboard currently. On lower tickrates you can see that the green one is updated faster than the white inputs
