Bug fix - Correct viewangles on load game

This is another one of those little Quake annoyances - when you load a previously saved game your viewangles are incorrect - you're normally looking straight forward instead of in the actual direction you were looking, which may have been up or down. Let's fix it.

Find Host_Spawn_f and declare at the top:

  Code:

float *sendangle;

Scroll down to the line where svc_setangle is sent (near the bottom) and add this between the MSG_WriteByte and the for loop:

  Code:

sendangle = sv.loadgame ? ent->v.v_angle : ent->v.angles;

Finally, change the body of the for loop to this:

  Code:

MSG_WriteAngle (&host_client->message, sendangle[i]);

Done - now when you reload you'll be looking in the correct direction. Easy as pie.

I like this one a lot. In fact, I wasn't aware of the problem.

Sadly I have NEVER saved a game in Quake....

Sweet, even works in winquake.

LOL people would play more carefully without savegame.

I mean i finish an episode, quit then come back to start 'nother misston, end the go again, oyd not like its that hard...

Thanks mh! This will be really helpful for me, since I often use saves to test features and bugfixes in my engine.

mh: heh, I'd never noticed. I guess I'd always saved in a near enough to horizontal state.

The error is actually worse than just leaving you looking straight forward: it's -1/3 of the correct angle: if you're looking nearly straight down when you save, you'll be looking up at a bit less than 30 degrees when you load.

Anyway, issue confirmed and fixed* in QuakeForge. Thanks for the heads-up.

*Not yet pushed due to technical difficulties with the git repository on sourceforge

I had an aguirRe type of thought.

Perhaps this behavior was intentional for keyboarders? I mean if you load a game and you are looking up or down, that isn't a keyboard initiated action so force_centerview isn't going to fix where you were looking.

Just a thought, but I'm thinking might not have been a bug but a feature.

(I also haven't thought about the code, so maybe I'm missing something obvious ... )

Hmm - "intentional for keyboarders" is a reasonable assumption here, but unfortunately in the absence of comments on the relevant code, we'll never know for certain.

All the same, pitch drifting would resolve that on the client side, and there is the behaviour that taniwha observed - it doesn't just auto-center, it sets your pitch angle to -(viewangle * 0.3333f). That comes from some SV_ClientThink code:

  Code:

   if (!sv_player->v.fixangle)
   {
      angles[PITCH] = -v_angle[PITCH] / 3;
      angles[YAW] = v_angle[YAW];
   }

We do know that "e->angles[0] = -e->angles[0];" is flagged as a "stupid quake bug" elsewhere in the engine too, so I'm thinking that balance of probability indicates that this one is actually a bug too.

This one definitely is a bug as you do not look straight forward when loading the game: you look 1/3 of the angle in the opposite direction. Quite bad news for a keyboarder, I'd say.

Anyway, problems with git fixed: pushed.

It's worth noting as well that this one is fixed in Quake 2.

This is a very nice fix. I never noticed how the load game angle was screwed up.

And this fix works properly with -mlook or +mlook ... so doesn't change even speculated behavior.

If +mlook, you stay looking at the ceiling if saved that way.
If -mlook, you load looking at the ceiling but it drifts down to level like force_centerview would.

It is perfect.
