How did DotA map able to detect your WC3 version is below 1.23?

[NightFelix]

Tittle.

 

[Rainther]

If GetHandleId(h) == null then
//Invalid version
endif

I'd guess they checked it GetHandleId works or not. But heck do I know, didn't even know it did that.

 

[NightFelix]

eh... I do not know much about what is JASS, so it that JASS?

 

[Rainther]

Most things in Dota is Jass also. And what I mentioned is Jass, yes. It's a new function implented into patch 1.24. And it'd guess using a function such as this and fail would make it able for the map to detect if version is <1.24.

 

[NightFelix]

If GetHandleId(h) == null then
//Invalid version
endif

So I just copy above that thing and paste it exactly?

If GetHandleId(h) == null then

wait.. wouldnt the writing that function on pre-1.24 cause errors?

and doesnt dota have 2 separate maps?

6.61b for 1.23-
and 6.61c for 1.24+

This would be correct. I can't see why there would even be a need for any patch detection, as any maps before 6.61c wouldn't be playable on any patch below 1.24.

Wopsie me then. I just drew a conclusion that was inaccurate.

Didn't know either if Dota could tell that.
