how to use "Sim.HandleMessage"

[noodle run]

I found some code by Sim.HandleMessage function, but i don't know how to use these.

public enum SimMessageHashes
{
  SimData_FreeCells,  
  AllocateCells,
  SimData_ResizeAndInitializeVacuumCells,
  ......
}

I found these code in "SimMessageHashes.cs" file.

I want to change the number of cells. These "message" seem to be consistent with my thoughts from the literal meaning.

Can someone guide me on this? thx

What do you mean "change the number of cells" ?

 

 

 

The number of cells (grids) is determined by world size. You can't change it after the world has been created.

hello FIXBUGFIXBUGFIX.

i think the "cells" just a memory block, it should can be modifiable.

I read the decompiled code of "Assembly-CSharp" and "simDLL.dll", I found that the memory of "grid" is stored in two different memory blocks "Assembly-CSharp" and "simDLL.dll".

The code for handling messages in the "simDLL.dll" library ("SimMessageHashes.cs") appears to allow modification of the number of cells.

But the problem is that I don't have any documentation for the code, so I don't know how to use it.

The image below shows the decompiled code of the simDLL, which uses the "new" operator for memory allocation.

Unfortunately, there is no way to modify the cell count of an initialized simDLL.

But certainly, you can determine how many cell should be initialized in an uninitialized simDLL.

You can achieve it by the following sequences:

• call SIM_Shutdown
• initialize a anew simDLL 
• Prepare a modified initialization data and call SimDataInitializeFromCells
