Quake3 Engine Entity Limit

[fontana]

I know that the current limit is about 1024 entities.
What i'd like to know is, how much entities could a mod (entity+) handle?
Would it be possible to bump it up to 4096 or even 8192?

The limit is used both in the engine and the game logic:

#define GENTITYNUM_BITS 10
#define MAX_GENTITIES (1<<GENTITYNUM_BITS)

With 1<<GENTITYNUM_BITS being equal to 2^10 = 1024. You'd have to make both a customized engine build along with its own game mod. So no, Ent+ wouldn't be able to do that.

Maybe I am a shmuck, but why did Carmack use bitwise ops there? Why not just #define MAX_GENTITIES 1024?

Because GENTITYNUM_BITS is also used...

Alright, I'm a shmuck. Thanks
