You 'abuse' the PlayerStatusHealthBonusImage image to 'fake' the health bar moving horizontally, you set HealthDeathWarning in the spectatortournament.res HealthIcon value to 1.001 and make the HealthBonusPosAdj the size of the entire player panel (where the health is the same size as the player panel)
Yeah man I had figured that much out, as is in my video, I'm pretty happy with the progress I made there.
WiethoofdThe overheal color is controlled by a drawcolor in the guihealth file BonusImage section and the actual low health color by the HealthDeathWarningColor in the HealthIcon in spectatortournament.
Yeah turns out that, in the mannterface at least, it's not a drawcolor, it's a different vtf used for the overheal colour, meaning that having just a blank overheal one with 0 alpha won't work. Unless I missed a way of specifying colours, and I tried pretty much every way there is, as far as I know at least. Cheers though man.
Edit: Forgot to link the final files.
