RL Kickback

[redrum]

I'm trying (unsucessfully) to get the players view to kick up a bit after launching a rocket.
I've tried this:

Code: Select all

                 if ((self.weapon == IT_ROCKET_LAUNCHER) && (self.button0) )                                 //kick
                      {
                      v_up = v_up * 1.33;
                      self.mangle_z = self.mangle_z * 1.33;
                      self.angles_z = self.angles_z * 1.33;
                      //self.idealpitch = self.idealpitch * 1.33;
                      //self.v_angle = self.v_angle * 1.33;
                      }

I commented out the bits that wouldn't compile.
Am I in the right ballpark?

I believe there's a specific thing for this, called punchangle iirc, which you set and the view is "punched" up by that far, and moved back to normal over a short time.

[Sajt]

Yeah, just set player.punchangle_x to -8 or somtehing (if not, set it to positive 8 ). It takes a while for it to ease back to normal though, so have fun...

[redrum]

Doesn't work, maybe b/c i'm using QW?

[Sajt]

I think QW might have turned it into a SVC message. I don't think it was even implemented though? I'm not sure, I've never really used QW.

In W_FireRocket(), you'll find stuff like this:

Code: Select all

msg_entity = self;
WriteByte (MSG_ONE, SVC_SMALLKICK);


Change the SVC to SVC_BIGKICK, but there's only smallkick and bigkick (used by super shotgun). If you want a bigger kickback, you should do stuff that I don't even know.

[redrum]

okey doke

[redrum]

SVC_BIGKICK doesn't seem to do anything,
I guess it's one of those QW things.
I'll figure something out. Thanks anyway.

[Orion]

Not at all.

Another note, QW was made to play online with a better ping than NQ, not to make custom effects, kickbacks, etc. NQ is better in custom effects, because it has particle() to create a particle of a specified color, punchangle_x, _y, and _z for the kickback, etc. That's why a "stock" NQ engine is really bad to play online, Darkplaces or FTEQW is better to play NQ online, but I prefer QW to play deathmatch, clan arena, or team fortress.
And I prefer NQ to practice against my bots, or play single-player.

So, if QW have particle() and other custom effect stuff, it'll be just like an NQ client, an awful unplayable laggy client. That was for lag's sake, that's why the shotgun smoke puffs don't spread in QW too. The tracelines spreads, but the smoke puffs not.

[Sajt]

particle() doesn't make the difference...

it's the other things... like QW's insane compression of nails...

[Orion]

I take a look at an NQ engine source code.
When I saw the TE_GUNSHOT effects, it's just a particle effect, if I call in QC a line like this:

Code: Select all

particle (trace_endpos, '0 0 0', 0, 20);


It will be EXACTLY like a shotgun smoke puff, so particle() in NQ reduces many lines of code!
The spikes hitting wall is the same particle stuff, but with randomized ricochet sounds.
Take a look at the sound stuff in the engine code:

Code: Select all

case TE_SPIKE:         // spike hitting wall
   pos[0] = MSG_ReadCoord ();
   pos[1] = MSG_ReadCoord ();
   pos[2] = MSG_ReadCoord ();
#ifdef GLTEST
   Test_Spawn (pos);
#else
   R_RunParticleEffect (pos, vec3_origin, 0, 10);
#endif
   if ( rand() % 5 )
      S_StartSound (-1, 0, cl_sfx_tink1, pos, 1, 1);
   else
   {
      rnd = rand() & 3;
      if (rnd == 1)
         S_StartSound (-1, 0, cl_sfx_ric1, pos, 1, 1);
      else if (rnd == 2)
         S_StartSound (-1, 0, cl_sfx_ric2, pos, 1, 1);
      else
         S_StartSound (-1, 0, cl_sfx_ric3, pos, 1, 1);
   }
   break;


the (rand() % 5) is just like (random() > 0.05) right? And notice that it spawns a particle effect with the same color as a gunshot, but with 10 instead of 20.

An explosion can be used as a particle effects, if you use 255 in the counter, the particles will be just like an explosion, 75 is the original explosion color, but no sound will be played.

If I wanted to add punchangle to QW.
I see that I'd have to add:

Code: Select all

.vector   punchangle;

to defs.qc.
What else would I need to do?

[Orion]

In W_FireRocket(), replace the SVC_SMALLKICK stuff by this:

Code: Select all

self.punchangle_x = -10;


But it might not work in QW...

[redrum]

Yeah, I already had that part.
Do I have to call a function like:

Code: Select all

void() Punchangle =
{

anywhere?

[redrum]

In combat.qc there is some code that makes the target move from the splash damage of a rocket or grenade:

Code: Select all

targ.velocity = targ.velocity + dir * damage * 9;

So I added this code:

Code: Select all

attacker.velocity = attacker.velocity - dir * 200;

The only problem is the direction in which the player (attacker)moves varies. Is there a way to make the player move backwards?
