Add custom VGUI2 HUD

[rtxa]

Custom VGUI2 HUD for health, battery and ammo. You can enable it with hud_custom 1.

Extra commands have been added to improve coloring of the HUD when health/ammo is very low or to use one main color for the HUD without changing all hud_color1/2/3 values.

Commands:

• hud_custom 1 - Enables/disables the custom VGUI2 HUD. Disabled by default.
• hud_dim 1 - Enables/disables dimming of the hud. Enabled by default.
• hud_color4 "255 0 0" - HUD color when health/ammo is very low (0%; 25%).
• hud_color_override 1 - Disables HUD coloring of health/ammo according to amount. Disabled by default.
• hud_reloadscheme - This reload the .res files of the HUD. This will refresh the HUD and display your modifications.

I recommend using these colors for the new HUD when hud coloring by amount is enabled due to the defaults ones being too dark.

hud_color1 "100 255 100"
hud_color2 "255 182 59"
hud_color3 "255 129 59"
hud_color4 "255 65 65"

Resources being used:

• Health and battery icons are from Half-Life 2.
• Ammo icons are from Black Mesa: Blue Shift.
• Font typeface being used is Hemi Head 426.

Thanks and I hope you like the new HUD and gets into the official client, people's feedback has been good so far.

Merged master and fixed conflicts: rtxa#1

Thanks, but I'm not sure if the history is gonna be clean, hope you can manage this or perhaps I can open a new PR and cherry-pick the commit with latest master changes and conflict resolved.

This looks really cool! Great work!

1. I don't think this works with WeaponMod, which can can add custom sprites. You can use the code from CHudDeathNoticePanel::PaintBackground to draw sprites in VGUI.

2. I don't like the wrapper methods in CClientViewport (like ShowHealthPanel, HideHealthPanel, etc). I think it would be better to add getters for the panels and call methods directly on them.

3. I don't like that old sprite HUD updates the visibility of new VGUI HUD. I think it's better to move all visibility updates to CHud::Redraw. Do something like this:

   if (g_pViewport)
   {
       g_pViewport->GetHudAmmo()->ShowPanel(
           hud_draw.GetFloat() > 0 &&
           m_iWeaponBits & (1 << (WEAPON_SUIT)) &&
           !(m_iHideHUDDisplay & HIDEHUD_ALL | HIDEHUD_WEAPONS))
       // ... other panels ...
   }

   Ideally, HUD code needs to be reworked to better support VGUI panels, but that's beyond the scope of this PR.

Add extern ConVar hud_custom to hud.h and use it directly

[rtxa]

Done

Move panel hiding to CHud::Redraw

On Linux, the text is clipped on the right-hand side. Probably because the font is italic and no one tested the game with such fonts.

[rtxa]

Weird that the font looks like this, we need to check if other Linux users have the same issue. I'm not sure if manipulating textinset key values in HudHealth.res can help with it. In any case, there is an option to set a different font by platform in section Fallback fonts from this link: https://developer.valvesoftware.com/wiki/Authoring_and_Using_TrueType_Fonts

About WeaponMod, I didn't know you can draw sprites in the VGUI2 panel. Anyway, when using custom ammo icons, it would fallback to a default ammo texture with a dot.

PD: By the way, why do we need to check g_pViewport all the time? Is there a way to ensure in class constructor that has been initialized, so we can remove the checks?

[rtxa]

Seems like in Linux, glyphs that are outside their bounding box are clipped/not rendered. On Windows, they do render.

I'm using online tool to test the fonts https://www.glyphrstudio.com/app/

[tmp64]

I changed the font to Arial on Linux as a workaround

That's a remnant from VGUI1 code. In BHL, the viewport is created once during VGUI init. Most checks can be safely removed.

I added sprite rendering for unknown ammo types

[tmp64]

Please, review my changes. I don't see a much better way to show/hide ammo panels, so I left it as it. If everything looks good, I'll merge this

Hi tmp64, thanks for adding the HUD sprite rendering for custom weapon, it's looks great with some weapons and still fits the style of the HUD.

Unfortunately, there are some minor issues that perhaps we can address in another PR, one of them is that the sprites don't scale well in lower resolutions. The lower the resolution, the bigger the sprite gets.

Other minor issue is that sometimes it doesn't recognize the correct secondary ammo icon.

Or sometimes both primary and secondary. I couldn't figure out why yet.

[rtxa]

I added some minor changes like: don't draw the hud when hud_draw is off or avoid overlapping of custom HUD with hud_weapon sprite. I also provided a Linux version for the font, it still looks almost the same, only required some tweaking on the width of the texts from the panels.

Font on Linux

hud_weapon no longer overlaps with the ammo panel of the custom hud.

I think it's ready to get merged.

Thanks!
