The basic HUD elements of the original have been implemented & recreated now to varying degrees. The mines counter still needs a tiny fix to get it working but nothing too difficult.
The health bar is going to be the most complicated part since the original's HUD has a kind of special effect that makes it change color depending on the amount of health you had. More health made it look more shiny & pretty, while less health made it less shiny & more reddish.
The shield generator bar will actually be a lot easier to implement since it's just a foreground/background graphic to indicate how much shielding is left.
The ammo capacity counters were actually a lot easier to figure out than I had originally thought, & displaying the integer number graphics was pretty trivial as well.
Displaying the keys in the HUD was easy as pie. I basically just use the InInventory command inside the SBARINFO lump & if the player has the key in their inventory, that specific key with 1 of 4 specific colors will be displayed on the HUD & in their respective slots.
There is still some more to go, but I have a better understanding of how the SBARINFO stuff works now, so expect the rest of the HUD to be recreated in due time.
Can you spot the difference?
Besides the crosshair that I've implemented, the console message at the top of the screen, & the weapon selection text at the center-bottom of the screen, it looks a lot like the original PS1 version.
I even made an attempt to line all of the HUD offsets up to the original.
That is the amount of love & passion that I have for this project.
