Want a custom boss bar for your map? Well, you can't just override vanilla textures because of how TF2 texture loading works.
So, we use the power of VScript and PD HUD to create a custom boss bar instead.
Available in 2 versions: with and without the numbers.

Incompatible with Player Destruction.

The Boss Bar has to be packed into the map to be displayed.​

Alternatively, launch your game with -insecure, then you don't need to pack it in while testing.

First, you need to create a logic_script entity with the following parameters:

Entity Script...........................custom_boss_bar.nut
Script think function..........Think

To make someone (a player or an NPC) a boss, call SetBossEntity(playerOrNPC) from your script or fire an Entity Output:

Targets entities named.......................name of your logic_script entity
Via this input..........................................RunScriptCode
With a parameter override of..........SetBossEntity(playerOrNPC)

Click to expand...

With Entity IO it might be hard to get access to a specific player. Most likely it will be activator.
