TASTools: Savestates and TAS Tools for Minecraft
Tool-assisted speedrunning in Minecraft demands precision that vanilla mechanics simply do not provide. For players who still swear by version 1.7.10, the modding scene offers a dedicated utility pack that closes the gap between raw gameplay and frame-perfect execution. TASTools: Savestates and TAS Tools for Minecraft is a Forge-based add-on built specifically for this older but still active speedrunning environment. It does not automate inputs, but it gives you the control layer needed to record clean, repeatable runs.
What This Mod Actually Adds
The core value of TASTools: Savestates and TAS Tools for Minecraft lies in its savestate system. Instead of manually copying world folders to test a single jump, you can save the exact game state and reload it in seconds. The mod writes a full world snapshot to a separate directory, and loading happens with a single key press, without leaving the game. This works even on LAN servers, which opens up cooperative TAS attempts that were previously impractical.
Beyond savestates, the mod includes a real-time pause feature that freezes the entire game, including multiplayer sessions. This gives you time to plan your next move without losing timing sync. The keystroke display is another practical addition, rendering your key presses on screen so you can review your own input sequence and match it to in-game events.
Speed Retention and Item Duplication
One of the most frustrating issues in 1.7.10 TAS work is the loss of momentum when using the save-and-quit trick. TASTools: Savestates and TAS Tools for Minecraft addresses this with a speed freeze mechanic. After loading a world, your character stays stationary until you are ready to move, preventing the impulse reset that used to wipe out accumulated velocity. The mod also stabilizes item duplication in a Forge environment, making resource-heavy strategies more predictable.
Supported Versions and Loader
This project targets Minecraft 1.7.10 exclusively and requires the Forge loader. It was created in 2019 and has not received updates since, so do not expect compatibility with newer game versions. The mod is not a playback tool like TASmod or LoTAS; it is a manual recording aid. If you need automated input replay, look elsewhere. For hand-crafted TAS runs, this remains a practical choice.
Installation Steps
To download TASTools: Savestates and TAS Tools for Minecraft, you first need a working Forge installation for 1.7.10. Place the mod jar into the mods folder of your Minecraft directory, then launch the game with the Forge profile. The mod should appear in the mod list. A simpler route is to use a launcher with a built-in mod catalog, where you can find the mod and click install directly into your active profile.
For those asking how to install, the manual method is straightforward: download the jar, drop it into the mods folder, and restart the client. Test on a fresh world before adding it to a large modpack, because the savestate system interacts with world storage and movement physics. Conflicts are possible with mods that alter similar mechanics.
Known Limitations
The mod has a few caveats. Reapplying speed on LAN servers is not implemented in 1.7.10, which the original author documented clearly. The project is discontinued, so bug fixes are unlikely. However, the savestate and pause functions are stable enough for serious TAS work. If you are building a modpack for speedrunning, test the interaction between TASTools and other movement or storage mods in a controlled environment first.
TASTools: Savestates and TAS Tools for Minecraft for Minecraft is best treated as a specialized utility rather than a general-purpose add-on. It does not change core gameplay mechanics; it adds a convenience layer over the file system and input handling. This makes it a safe addition to any 1.7.10 Forge setup, provided you verify stability with your existing mods.
In practice, the workflow is simple. Set up a savestate before a difficult segment, attempt the maneuver, and reload if you miss. The pause feature lets you review your next action without pressure. The keystroke overlay helps you refine your input timing. These three functions cover most of what a manual TAS runner needs on a daily basis.
If you are new to TAS speedrunning, this mod gives you the same fundamental tools that emulator users take for granted, adapted to Minecraft's engine. The version lock to 1.7.10 is a limitation, but for that version, it remains one of the most functional savestate solutions available. Download TASTools: Savestates and TAS Tools for Minecraft from a trusted mod repository or launcher catalog, and you will have a reliable base for your next speedrun project.
Ultimately, the mod fills a specific niche that vanilla Minecraft leaves empty. It is not flashy, but it is effective. For anyone serious about tool-assisted runs on 1.7.10, this utility pack is worth the setup effort.
