Simulatica
What Is This
Simulatica is Simulation + Litematica. It is designed to run block and entity logic within Litematica projections.
How To Use
-
/simulatica start <litematica file name>— Start simulating a projection -
/simulatica stop <litematica file name>— Stop simulating a projection -
/simulatica execute <Command to execute in simulated space>— Execute a command within the simulated space
Once a simulation has started, switch to mode 10/10 to interact with the projection.
How Does It Work
Once at least one simulation has started, a local integrated server is created on the client thread. It initializes a completely empty dimension and loads the target projection to be simulated into it.
Note that this means:
- Projections being simulated cannot overlap.
- Adjacent or near by projections can affect each other during simulation.
- Client-side lag may increase.
- If the simulated integrated server becomes laggy, the client will also be affected.
