Basic Tutorials

[XSeth2kX]

does anyone have a basic tutorial that shows how to edit weapons and get me started?i've beeen to most of the quake3 tutorials but im looking for somthing meant for jk2 im not srue if any of it will work with jk2

 

 

also i foudn a code for hud scorboard will it work with jk2?

I dunno if its possible to ADD new weapons in JK2, I haven't tryed that yet (I am still mapping the code areas), but it is possible on Quake 3 (as you may have observed on Code3Arena).

 

I've noticed some different coding on weapons in JK2 that differs on Q3; like there are some constants defined in 'g_weapon.c', and the weapons firing behavior are in there, and the missile behavior (the laser bolt or missile itself) is in g_missile itself.

 

I was under the impression (I haven't checked Q3 code) that some of the JK2 weapons code are a little more 'spreaded' around than Q3 one. But, the basic structure is there... My suggestion to you is: backup the code, and try it yourself anyway, and even when the Q3 codebase looks different find out where it is on the JK2, and modify it yourself. The search tool is a powerful ally...

 

As for the scoreboard: At first glance, yes, and the same suggestion above remains...

 

I hope it helps...

I was working on one that works with JK2, but it's largely incomplete. It is a part of my personal 'code' cliffnotes, I was able to add a copy of the Bryar Pistol using it, and make it fire rockets. There's a lot of stuff that I didn't get to, that appears to be client side 'friendly' code, basically when the item is precached it shows a "Loading ..... ??"

Aside from what I have there, you'll also need to alter the actual firing function in g_weapons.c, as well as the alt-fire, and a

 

case WP_WHATEVER:
WP_FireWHATEVER( ent, altFire );
break;

 

in the void AnimEntFireWeapon( gentity_t *ent, qboolean altFire )

 

and then ... voila, you kind of have a weapon that you can place. You'll also have to alter the mp_entities def ...

 

as well as

inv.h

 

and one other place so the damn thing actually shows in game. I've been looking, but I'm not at an IDE right now to be able to find it. look for weapon_bryar_pistol, basically it's 'like' a spawn function, but it's not in g_spawn.c. I could be wrong, but I beleive this last part is essential so you can actually 'pick-up' the weapon, and place it and such.

 

Somebody more brilliant than I will add their extra bits of wisdom below:

[Wudan]

Oh, and remember to keep anything that relies on WP_NUM_WEAPONS in a nice orderly fashion

 

Oh yeah, and there's a lotta client stuff that I didn't even get to changing.

[AlzWisHum]

Very nice work.

 

Good to know it is possible, I've actually thought about adding a weapon, just by replicating every weapon whetever it shows. Looked simple as that, good to know it is...

 

Thanks for sharing!

[AlzWisHum]

BTW I'll try later to make it work also, my Mod will also requires this implementation.

 

I actually was thinking JK2 could be restrictive about the creation of new weapons, and I was thinking (as a plan B) about making the 'new' weapons as their respective slots like: Weapon #1 for the Soldier is a gun X, while Weapon #1 for the Bounty Hunter is a gun Y, etc... So when a Bounty Hunter fires his weapon #1, the Mod will check his id and will go for Y, when its the Soldier fires, it'll be X and so on...

 

Thanks again.

To answer the original question, yes, most of the stuff you can find on Q3 programming applies directly to JK2. The big difference is the Ghoul2 implimentation and the related .gla/.glm mess that Raven made. Some stuff is a bit different and other locations, but you can basically figure out everything, EXCEPT animation crap, from those tutorials.

So with this information it would be possible to use the E-11 blaster, the Battle Droid rifle model and say that sniper rifle all in the same mod?

 

this would be a giant help for my disaster in progress

[razorace]

It depends on how you do it but, yes, it's possible.

[Wudan]

Yeah, there's sections that I didn't even get to, I was just starting to crack that nut

 

Anyway, I think I need to get myself educated in C all over again, so I'm starting to write some simpler stuff, then extra mover code, then weapons then animation (animation is so hard a nut, that only one coder that I know of has even begun to crack that nut)

[razorace]

You mean redoing the low level animation code? I guess you could if you want but there's no real need unless you're doing it to make it work with new animations.

[12345678]

i was wondering about two avenues to new animations in JO. the first was to rip the animation code out of q3 (if the source code for that was released, dunno at this point) and stuff it into JO.

[12345678]

the other was to take a skeletal anim system i found at sourceforge and see if its worth plugging into JO and getting it to work right.

[12345678]

either way, you still have all the old stuff available, plus you could add new anims with the new skeletal system. only tough part might be making the two blend well in game.

 

guess ill tackle that in two years when im able if no one else has done so by then

[Wudan]

Jk2 Already has skeletal animation.

 

Quake3 anim is out of the question. We're trying to move forward, not backwards

[razorace]

that and the fact that the ghoul2 system is hard coded into the executable.

[12345678]

hehe, yeah, i came back here to delete the quake 3 part, where did i get the idea q3 had skeletal anims? mustve been bc rtcw and jk2 have it

[12345678]

as far as the ghoul2 system being hardcoded into the exe, that doesnt mean you cant implement your own system to work alongside so you can add new anims, right?

[12345678]

wudan you mentioned that jk2 has skeletal animation already, but we cant make new anims for it, right? is it going to be easier to make a new skel system or just crack the ghoul2 system?

[12345678]

btw, sorry everyone for the cheesy posts, for some reason my isp doesnt like some forums, the posts are as big as i can make them. otherwise i get a "page cannot be displayed." combine this with the 90 second post limit for an infuriating forum experience.

[razorace]

We gotta just crack the current system. It's the only way.

[12345678]

here's a code dump of a "simple skeletal animation system" from gametutorials.com.

 

its all greek to me but maybe it'll help someone else.

[Wudan]

Nah, forget that. And it's not really "cracking" the JK2 skeletal animation system, it's just a question of puppeteering

[razorace]

Whatever, all you gotta do is hack it so it can run new animations. I doubt "puppeteering" has anything to do with this code hack.

[Wudan]

whaaaaa ....

 

What the h3ll are you going to hack/crack? You sound CRAZY!

 

You release one version of your mod and you go and get delusions of grandeur
