Metro-Police Alt-Firing

Mapbase v3.1 gives metrocops the ability to use the AR2/SMG1 alt-fire, just like Combine soldiers and citizens. This means all 3 types of NPCs can use both abilities equally.

They use the "Grenade capabilities" keyvalue and input previously only used for citizens. Metrocop grenade functionality should stay the same in existing maps, but in any maps created or modified with Mapbase v3.1, they must now use the "Grenades" setting on the "Grenade capabilities" keyvalue in order to use normal grenades correctly.

Limit Changes

A bold Source modder (ficool2) recently experimented with raising various limits in VBSP and discovered that many of them were not engine-bound, meaning they could apparently be changed without consequence. He suggested these limit changes for Mapbase and they are being introduced with Mapbase v3.1.

The following limits have been changed:

  • Maximum VBSP entities has been raised from 8192 to 65536
  • Maximum VBSP worldlights has been raised from 8192 to 65536
  • Maximum VBSP overlays has been raised from 512 to 8192
  • Maximum "clientside renderables" has been raised from 4096 to 16384

The VBSP entity limit is separate from the in-game entity limit. The VBSP entity limit change mostly just allows VBSP to process more internal entities, most notably static props. ficool2 managed to compile up to 16384 static props into one map. Thanks to the "clientside renderable" limit change, he was even able to render all of them at the same time.

These changes are highly experimental. Feel free to push these limits and please report any issues with them.

This update took a very long time to release because I have been busy working on Entropy : Zero 2, and that is still my main focus at the moment. I mentioned in the previous update's article that I was planning on starting the MP port fairly soon after v3.0 is wrapped up, but I have not gotten the chance to do that yet. I have some solid plans for it, but I don't know how long it will take to finish after I start working on it. If it doesn't take too long and no other big features need be released before the MP port is done, it may be safe to expect Mapbase v4.0 to involve the MP port in some way.

If you find any issues with this update, please report them here or on the Discord server.
