I made many changes to the server side to get the following things:

• 4096 or more up to 16384 entity limit.
• 4096 visible entities, while previously there were only 256.
• different func_breakable and their limit of 4096
• weapon limit of 8192 weapons
• physics, objects push each other, take damage from collisions and can float and lie on each other and fly beautifully
• many built-in functions and removed unnecessary code
• NPCs, entityplus code with my feature save and load for Big maps
• NPC groups such as citizen, enemy etc, they react to each other differently, and not all communicate with the player
• multiplayer support for entityplus and more things maded by me

also rewrote the client part to add hud customization, player customization and a beautiful hud and good fonts

also made a scripting language that works in 3 spaces, game, cgame, ui

the scripting language can create interfaces in ui.qvm at the moment, and it is easy like .cfg files.

if you have any questions or any tips on modding, i can help you with modding quake 3 or making mods. :)

I know nothing about programming, but have messed with Q3/OA a bit. I have an older mod (lvlworld.com/mod/id:45) that has a limitation of making the gun disappear when too many gibs are on screen. I don't know how (if possible) to decompile .qvm files, but was just curious if you might be able to use your rewrite to possibly fix it, so on modern systems you could add as many as you want, and not have the gun disappear? No idea if it is feasible or not, but wanted to ask anyways, as it has been on my mind for a long time, and one of the favorite mods we play with in our family.
