[reference] CoD2 engine limits

Back in the days there was a thread on modsonline about limits of the CoD2 engine.

I thought it would be nice to make a similar thread here.

Currently:

General:
Gamestate: 16k (1.0/1.2) or 128k (1.3) (serthy)
weapons: 64 or 128, but bugs out after approximately 48 (izno)
Max string length: 1024 (for cvars and in script)(serthy), 256 (for iprintln and probably iprintlnbold too)(izno)
Max client cvars: 1000 minus the default ones (serthy)

Menus:
Max precached: 64 (serthy)
Max actions in a menu (OnOpen etc): 42ish (serthy)

Players:
headicons: 16 (serthy)
statusicon: 8 (serthy)

Any other limits you want to have listed here, any ?? you want to have filled with your value or spotted an error? Reply :)

I remebered those:

General gamestate:
1.0 16k
1.2 16k
1.3 128k

app. max actions in menu event (a la onOpen): 42

max precached menus: 64
max precached statusicon: 8
max precached headicon: 16

max cvar string length: 1024
max count client cvar: << 1000

Max "newHudElem()" is 32 I believe.

Probably the same with "newClientHudElem()" but haven't tested.

I wish there was a way to increase the limit D=

Selbie told me there is 32 limit of newHudElem and 32 of newClientHudElem.

And why 64 menus? On 1.0:

******* script runtime error *******
Too many menus precached. Max allowed menus is 32

Anyone know what the max number of script variables is? I've not hit it yet (because I haven't had a hard server crash), but I suspect I must be near it, because the game looses track of players leaving and returns an "undefined is not an array, string or vector" to prefect code in callback_playerDisconnect(). This tells me there is something wrong and I must be borderline with some ceiling limit. I just can't figure out what it is.

I thought max vars were approx 65k, but dont quote me on that

I had this error yesterday.

Code:

---

ERROR: G_FindConfigstringIndex: overflow (846): 'fx/un/20mm_tracer.efx'

---

I had probably too many loadfx.

You can also have max 64 map name in one or more .arena files. (above 64 it shows just the default mp_***)

Edit: when i don't load the shoot through wall script from IzNoGod then the overflow is gone. (it has 23 loadfx)

Max array size: ~4096

script_brushmodel 256 or so (soft limit should be around 200, since at some point nades are invisible etc.)

objective_add is limited to 16 objectives. (0 until 15)

PHP Code:

---

if ( *(_DWORD *)v7 < 0 || *(_DWORD *)v7 > 15 )
{
    v0 = sub_80B7FA6("index %i is an illegal objective index. Valid indexes are 0 to %i\n", *(_DWORD *)v7, 15); 


---

Also compared to cod4 the states are limited to 3 (empty, invisible, current).

jk;
good job

Xmodel limit: 255 unique xmodels or 1024 xmodel in total (G_ModelIndex: overflow)

Client commands for outputting entities (to server console): printentities, entitycount (this one requires cheats).

Max menuDef is 128

Code:

---

UI_AddMenu: Maximum number of menus 128 exceeded.

---

Maximum number models you can attach to an entity is 8.
Maximum number of turrets you can spawn is 32.


Also not sure if this should be classed as an engine limit or bug, but character animations do not get reloaded if you have previously joined a server. You are required to restart cod2.

Сan "raise" limits? Change the game engine?

The amount of objectives is hardcoded clientside last time i tried anything with it, so thats a no-no.
Amount of menus is probably overrideable, but you would have to alter other configstring indices to get it to work properly
xmodels can be shown unprecached using configstring alteration already, so no need to up that limit anyway
turrets: i dont see how anyone would need more than 32 turrets on a map, will lagg the server anyway if all those are in use. If you need more turrets, just add them to the map itself maybe?
attach: im not gonna burn my fingers on such delicate (shit) code
g_modelindex overflow is also triggered by too many trigger_use_touch, so limit those in your .map (all trigger_use_touch objects ++ the modelindex counter)
gamestate: hell no (however you can add tricks like sending precaches AFTER the client connects. Is quite hard and requires some custom coding so could be doable)
weapons: they bug out after approx 48, so increasing the limit from 64 or 128 to a higher number is useless. Just modify the weapon's parameters using the libcod functions or write some of those yourself
string length has been patched (non-libcod patch), but only internally. Still, getting to over 1024 chars and you're doing something wrong imo
cvars cause a clientside crash, so thats clientside hardcoded
headicons: hardcoded clientside (spent waaaay too long figuring that out)
statusicons: see headicons
hud elems: using over 32 hud elems is generally ill advised, but might be patchable to a higher number. havent tried.
script vars: 65k is 16bit unsigned integer, so changing that will require a MAJOR overhaul of the ENTIRE engine, so dont even go there
entity limit is 1024, but ents become invisible after 256 ents are shown (so you can add a ton of script_origins on top of visible ents), but i'd assume this is limited clientside

And if you imagine it is that all the players on my server will pump not only fashion, but also all the files are in a directory "Call Of Duty2" Full game (Server launcher)

Again, like in the other thread, this sentence makes no sense at all. Please learn how to form proper english sentences before you speak

This you need to learn how to use translate.google like this I use, and learn how to talk to people, respectively not be bastards!

I do not need to learn how to decode your google translate mess as this is an english forum, so you should at least make yourself understandable in english. If you fail at that, you can try google translate, but that is not a guarantee that the result will even form any kind of logical sentence (protip: YOUR SENTENCE MAKES NO SENSE)

What's the xmodel triangle/face limit?
