Low HP Indicators

Short: Silent version to be installed on servers.

Long: I've done everything I can to make the mod exclusively client side, this version has silence in place of all sound effects.

This is intended to be installed server side only, but has all the other code in case something is actually processed server side, so this mod version works client side too, just without the sounds. Server doesn't complain about client/server mod versions, performance has even improved slightly.

If anyone knows how to make this purely client side, I'll gladly give you the files to be the new dev.

• rewrote audio event code for client side only sounds.
• added pitch variance to the default disabled breath sounds, they're almost okay to have on now.
• rewrote overlay code to process on the client instead of the server, this causes the pulse and sounds to change speed if your FPS dip below your Max FPS. If you're getting weird low HP indicators, it's probably because you've set your Max FPS higher than you can produce.
