Engine question: CellClass::Adjacent_Cell

GREEN · Light Infantry **Joined**: 26 Dec 2016

I have seen ts-spawn.exe enter into a doom loop .
Might be something on a map causing it, some of the time.

Have ye debugged something similar yet?

Code:

//0050077C push esi
//0050077D mov ecx,ebx
// DEFINE_IMPLEMENTATION(CellClass &CellClass::Adjacent_Cell(FacingType) const, 0x00457970);
// DEFINE_IMPLEMENTATION(CellClass & MapClass::operator [] (const Cell &), 0x0050F280);
//0050077F call 00457970
//00500784 cmp eax,ebp
//00500786 je 00500791
//00500788 dec esi
//00500789 and esi,7
//0050078C cmp esi,0FFFFFFFFh
//0050078F jne 0050077C

How to indentify the CELL it is looking at so i can check the .map file?

?How do i dereference from what registry calling 00457970

If the game is getting stuck in an infinite loop, make sure you are using the latest compatible version of the ts-patches EXE from https://github.com/CnCNet/ts-patches/releases/tag/latest (ts-patches-TSCLIENT-master-#.zip).

After updating the EXE you still get the same issue, then you might have a patch conflicting with existing Vinifera code or your code might not be handling the cell lookup correctly.

If you wish to discuss this in further detail, you can join the Vinifera channel (#vinifera-chat) on the Mod Haven Discord and we might be able to provide better insight once we can see your code.
