A Dead Space style ammo screen that shows up on your weapon. There are GUI menus for changing the color of the screen, and the size & attachment point of the screen. There are screenshots of the menus on garrysmod.org, here is a video of an early version of the screen:
A note on the height/attachment point settings: you’ll probably want to adjust these settings for each weapon, as the screen will appear different on each model. Use the “ds_gunhud_editor” command to open up the GUI for this.
To change the color of the screen, use the “ds_gunhud_color” command to bring up the GUI.
(You can also bind these commands to keys for quick use)
