I noticed that custom menu and weapon files are not loaded when you join a modded server, for example with the promod_v3.3. So I said to myself why not fix this and came quickly up with this solution.

Requires the reconnect patch I posted here: viewtopic.php?f=17&t=26688#p225039

 

Greetings to banz, this is for you. I want to thank you for all your contributions.

Sweet! I hope something like this will be included!

Ah, the bug that has plauged mods that load custom assets. Nice work on fixing it, should really be implemented into the client.

Nice job! I can add this into my dll.

Thank you zxz0O0 for making and sharing this. I really appreciate it.

Now, lets hope this or something similar gets officially added to the client.

You and Zebra, great work as usual.

Mmph I'm crashing once it tries to restart. Can you attach the .cpp instead? (I feel like I've messed up somewhere. But don't know where.)

they aren't loaded because fs_game is set after fs_startup process, fix this and you won't even need to reconnect.

Seems you didn't read the code. That's exactly what I do, it's just reconnecting when you need to download the mod (not even sure if this is needed but IW3 also does it).

ups, yeah, I guess you are right, the code it really messy, but thanks for showing us proof of concept

I'd appreciate any try to make it better.
