Minecraft TAS Simulator Mod

For Minecraft 1.8.9 with Forge

This is a mod providing an interactive simulation of Minecraft's player physics, to be used particularly in experimenting with TAS movements. It is able to replicate some movements such as movement keys and camera movements, which may be useful for looking at parkour and movement mechanics.

This mod is able to:

• ✔️ Use Minecraft's physics engine itself to emulate player inputs
• ✔️ Visualize the player's trajectory
• ✔️ Simulate the basic keys for movement, i.e. WASD
• ✔️ Simulate mouse movements
• ✔️ Often provide a accurate-enough precision for deterministic parkouring

This mod is not able to:

• ❌ Manipulate RNG
• ❌ Be considered a valid TAS (by itself)
• ❌ Simulate all keyboard and mouse inputs
• ❌ Simulate sub-tick movements
• ❌ Simulate GUI interactions
• ❌ Play with savestates
• ❌ Provide a "bare bones" simulation that is either machine-readable or built from ground-up

There are other mods that may provide these functionalities, such as TASmod.

For more information on TAS (tool-assisted speedruns), consult TASVideos (for TASes in general) and "An introduction to Minecraft TASing" by Scribble.

How to Use

You can find a built jar at the releases on GitHub. Alternatively, you may clone the repository and build it yourself.

You can find the controls in controls.md.

TODO

This mod is not yet ready for use other than myself, hence the pre-1.0.0 version. I don't know if I will ever get it out of it.

minecrafttassimulator's Issues

The positions of horse does not get updated to a precise value

The horse's position is sent from the server in increments of 0.125. This means that from the client the horse appears to be placed in a grid of 0.125 blocks wide. The issue is that while we get a decent consistency (other than desyncs caused by lag), we are unable to record the precise position of the horse. See the image below.

Note that the player's position, which also updates relative to this coarse value, does not need as much attention.

The movement of horse appears random while riding it

Look at this issue in MC15SecondsRNGRigger. Basically, the horse's position appears differently every time.
