 |

Weapon fire code refactoring ?  What's that ?
He he, I'm just talking about the last revision I committed today: 1.1 branch rev310.
So here is my published comment for that r310 (with original typos  ):
| sg_tequila wrote: | Weapon fire code refactoring:
- Added Weapon_Trace API to easily add trace debugging entity in debug build
It is now possible to visually debug trace on client side (only in debug build)
- Added g_debugWeapon cvar in debug build
- Review some code in prevision to higher refactoring:
FireWeapon & ShotgunPellet should share some code in next update
Weapon fix:
- Really check we are not shooting ourself
Media added:
- Added shader and picture to draw trace debuggung entities
- Added sg_developer.pk3 PAK creation and copy in copyfiles-debug target |
So I rewrote some part of the API, that's a real weapon fire code refactoring. That wasn't my real goal at the beginning, but I was checking some "entities" problems to have my final "stucking bug patch" working for the next beta release... And I triggered some bugs... Yeah, that's my job  I like bugs as they're scratching me
Then to beat that new bugs, I wanted new tools around the weapon fire APIs and the major one for which I published this rev310 is the availability to visually debug the trace system... What's that ? That's the bullet collision calculations toward enemies and windows to break 
Anyone involved should review the code and help as he can.
That weapon fire code refactoring is a first stage as it still show me many trace bugs... Especially in the shoot through walls stuff... So it's really time to fix all that old and nasty bugs, guys... My stucking bug patch will wait.
To illustrate, I uploaded a video on the video section of my Moddb profile:
I'll try also to upload it on my Youtube profile.
I'll prepare another video with what I still noticed but if any coder want to help now, you should know BG_ShootThruWall() API from bg_misc.c is completly bugged and really need a big refactoring.
Few bugs to fix because of BG_ShootThruWall:
1. Can't shoot through doors and some other entities, like first shoot in a window won't go through...
2. Can't shoot through curves
3. You can shoot through 3 to 4 solid walls (not wood), here that's the thickness balance which seems bad.
For the ones, wanting to test the trace debug system, you'll need to build a debug release as that system won't be released in official releases. Then you'll have to create a sg_developer.pk3 with the /misc/media stuffs I added (linux users should use copyfiles-debug target). Setting g_debugWeapon will do the rest. Hum I really want a wiki to describe precisely all the process

or the shotguns!
it looks like the bullet hit decal is of from the actual bullet trace?

| Neat. I have been thinking that something like this could be built into a training level to let he new folks work out how the weapons work. |

Indeed
About the decal, network traffic is optimized and vectors are rounded to integer. So the client side shown traces are approximated. Btw they are not on the server side, so don't worry about this. You should know the trace "beam" is approximatively 2 units large... so 1 unit between the trace middle and the light edge.

That could be an idea, but for now I just prefer such stuff for developers only as it can be used to cheat... by just showing you for 30 seconds where you were

I've tried some long distance shooting in el paso using this feature combined with my own patch, and it's a really great way to see the effect of different spread values. Nice job, Tequila.

Maybe your dream will be realized
I finally activated the stuff in the 1.1 branch starting from r372. Next beta release will so incorporate that stuff by default.
Btw it was also accidentally built in the current v1.1b1 engine (my mistake, one more...).
You'll be able to test that in single player game by opening your console and set g_debugWeapon to 1.
Btw before releasing that next beta release, we may improve the look and feel of the displayed traces. As you can see, the trace is most like a blue ray. It uses the following trace.jpg picture colorized in blue by the code:
and the following shader:
| Code: | weapon_trace
{
nopicmip
{
map textures/developer/trace.jpg
blendFunc GL_ONE GL_ONE
rgbGen vertex
}
} |
What do you think ?
If you want to test with current v1.1b1, you'll need the following PK3: sg_developer.pk3
Feel free to edit that PK3 and propose your own here.

Okay, so which engine and which game versions are you using ? On which platform ?
Report also your console output so we can verify which versions and which PK3 are loaded. |

What sort of improvements are you looking for? A more defined trace?

im on v1.1b1 on Windows XP
from my console output it seems that its loading the developer pk3 first then overwriting it with something from the other pk3's? thats the only thing i can think of anyway...

EDIT: something interesting i noticed. in 1.1 the pk3's are loaded in backwards alphabetical order! 0_0 although i just tried renaming the developer pk3 and even though it loaded last i still didnt get that cvar...

Right now, the system is using native RAIL CORE rendering. The rail core is using r_railCoreWidth cvar (6 by default) to draw the picture on the surface defined by the trace origin, trace end and r_railCoreWidth. You can set r_railCoreWidth to 1 to create thiner trace. Btw, if nobody complain about the blue shape, we will keep that.
About the shader, I really don't know if it is correct. I'm more than a noob in shaders.
@ Sucalakafufu: Do you have old binary DLL for the game ? We can't see with your cut console output what is really loaded. |
