[Solved] My map doesnt appear on the list of maps

[Mr_Loap]

Hi,

I have a map that I have saved (in the right place) but I cannot find it when I play.

This problem exists since I have copied and pasted a custom spell in it. I think I have done it properly, I mean the spell works when I play the map from World Editor.

I do not understand why the map is "invisible" then. It isn't the first time I copied and pasted that "kamehameha" custom spell in a map and until now it always worked well. I have other maps with that same custom spell which work perfectly and are playable on Battle.net.

Here it is :

The non-working "invisible" map contains a lot of triggers and imported units which could possibly complicate things with custom spells. Maybe there is a maximum number of triggers in a map. Also the map is pretty big, 6 Mo.

Any solution or advice ? Has anyone faced this problem before ?

The filename is too long, shorten it and it will show up.

Thank you very much LordDz

My problem is solved

Keep map file names unique, short and with a version number. Eg "LoaP DW v1.w3x". With each release you can increment the version number so that people always can tell which file is the latest and there are no name collisions with earlier map versions.

I've just encountered this problem with 1.27 client. Same reason: file name of the map was too long.
I didn't know about this and ended up wasting a lot of time, because I relied on the map showing up/not showing up when I edited war3map.w3i.

Exact numbers:​

Is visible?	File name length (with .w3x)	Full path length	Full Path
yes +	45	79	C:/APP/Warcraft III - LAN/Maps/10/yweogdfyisgafyigweqyrcqprqwevnipryvqwubor.w3x
no -	46	80	C:/APP/Warcraft III - LAN/Maps/11/ryweogdfyisgafyigweqyrcqprqwevnipryvqwubor.w3x

Possible explanation: Strings in C, C++ end with a \0 (null). This means when array has 80 character slots, you can store 79 letters + final \0
If Warcraft 3 only allocated an array of length 80, you cannot have total path lengths > 79 characters.

PS: On top of that, I have 8dot3 names disabled in registry. Why? WorldEdit has long bothered me by shorting map names: mapgoo~1.w3x. I don't think this causes any differences here though.
PPS: This issue was fixed in Reforged, since they had to use long names when putting maps in folders like ./Maps/<sha1-hash>/mapfile.w3x. A full path length of 127 works. But I doubt they support full 32k long names that are possible with Win32 API.

This would be incorrect API usage. The array should have been defined with a size of MAX_PATH.

Maximum Path Length Limitation - Win32 apps

Maximum path length limitation.

But I guess it is not surprising given that Player(-1) used to cause an application crash...
