[Crash] Can't host old map

[totony]

Hey folks, I've been trying to host this old map from 2008, but it just starts the lobby, cancels it, starts it again in a loop and wont let me host.

Any idea what causes this? I tried looking through the JASS for clues but I have no direction for search so its not going too well.

I attached the map

It's probably from pre-1.24b when the H2I return bug was removed. You need to edit the map script, find something that looks like this:

function H2I takes handle h returns integer
  return h
  return 0
endfunction

Comment out the existing lines and make it look like this:

function H2I takes handle h returns integer
  //return h
  //return 0
  return GetHandleId(h)
endfunction

Assuming other type casts are not used as well.

I get the same thing for maze designer by dashival, trying to open the file in the editor causes crash or says "unit data missing or invalid". Would this be caused by the same issue/fixed in the same way? I really want to re-play this!...

This usually means the map is "protected".

What else would there have been? Was B2I a thing via typecast? I guess maybe typecasting widgets <-> unit/destructible/item?

I have all of this which I'm not sure how to convert, any idea?

function Rect2Unit takes rect R returns unit
return R
return null
endfunction
function Unit2Rect takes unit U returns rect
return U
return null
endfunction
function Loc2Unit takes location L returns unit
return L
return null
endfunction
function Unit2Loc takes unit U returns location
return U
return null
endfunction

You are gonna have to use a tool like MPQ Master to open up the map if it is "protected"
You cant use the world editor

nvm there's a whole library in there, too many functions to fix. Anyone made a converter or something? I think it's using something "This map contains the Commander and AMAI"


might use this? Jass NewGen Pack [Official]

EDIT: Found this: Make a Map Work for Patch 1.24 - WC3 Modding Information Center will try

What else would there have been?

Since there were no hashtable the type casts were used to go from integers which could be stored inside gamecaches to unit or other complex types.
