Map restore!

[mokarecman]

As the tittle says, is there anyone here that is able to restore a old map from 2009 to be able to run on the latest wc3 patch ?

It's impossible except reorganize the whole map script manually, due to the fixed return bug in version 1.24, which will eventually take a lot of time.

Damn, tnx anyway.

Not true. I managed to fix several maps. I cant promise a 100% restore. But it is do-able and not that hard to be honest.

Are you going to make a tutorial for the rest of us?

No. As I said before. It is possible, but you will NOT maintain 100% of the map data. Also the ways I know are not 100% guaranteed to fix all the problems.

Ok, but any info will help others at least try to restore a map.

That means you still have to do it manually, which is actually quite hard for me, since i just learned to edit warcraft III map when version 1.24, so i actually don't really understand what is return bug. Perhaps you could explain more to me

Code: Select all

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

This is the return bug. From what I gather, this double return function was served as a way to convert data types. In this example, it will convert a handle to an integer.
On the new version, JASS decided that a function can only return one value, instead of two (or how many there were) so this function would NOT work.
The way to get around it, is to manually convert the datatype yourself. For the example above.

Code: Select all

function thisIsABug takes handle h returns integer
return GetHandleId(h)
endfunction

GetHandleId converts the handle given to an integer value of sorts... Same way the function I2S convertes Integer to String. R2I is Real to integer, etc...
