Title: Hud Not Centred
Post by: CKid on June 20, 2008, 08:19:11 pm

Hey guys, It's me again with another problem involving 03-14-XT build. My primaries and hud crosshairs does not line up. Depending on the fighter that I select, the shots are off by a few degrees. I think my hud is not lined up correctly with my screen. My monitor is not a widescreen and running at 1024 x 768 ingame.

I get this with newer builds as well, all recent kara builds, plus Wanderer's recent build. (080611)

It may be a problem with the view slewing TrackIR stuff. Can you post a screenshot please?

Not using TrackIR.

Maybe it has something to do with faulty viewpoints (or are they called eyepoints?)

I doubt it, it happens with every ship.

Is it with all campaigns?

Yep, looks like you introduced several bugs with that feature.  See the first attached screenshot, for example.

There are a number of issues here.  First of all, you neglected to include the HUD_nose_x and HUD_nose_y in all the appropriate places, so the FS1 HUD no longer aligns properly.  Second of all, it looks like your HUD_get_nose_coordinates function does not default to 0 -- which it should -- when the viewer is level and pointed directly ahead.

I've added the missing HUD_nose_x and HUD_nose_y offsets in hudreticle.cpp so that the FS1 HUD now displays properly; see the second attached screenshot.  However, the centering code is still broken.  I've disabled it for the time being, so why don't you take a look and see if you can fix it.  I bet once you fix that bug, this thread's bug will be fixed as well.

Nice method of lighting a fire under my ass. :D

Two things are affecting the accuracy of the nose calculation for the HUD. First, I scaled the ship's forward vector too small of a value. The prior calculated magnitude was probably too small to give an accurate vertex projection. Second, I forgot to unscale the projected offsets from the unconventional resolutions to the Freespace defaults. I didn't know that a gr_unsize_screen_posf existed until today. :)

So yeah, bug fixed. It's in the SVN repo.

Much better. :yes:

However, it's still not 100% fixed. :p When the viewpoint is level and straight ahead, x is 0, but y is 1.

Okay, I've gone and scaled the forward vector by 10000 instead of 1000. I seem to get (0,0) now for the HUD offsets when centered. Hopefully that'll end this bug once and for all. :sigh:

Yup, that seems to have fixed it. :)
