NPC Prop Attacking & Breaching

Update as of 08/30/2025

- Improved prop detection
- added new console command wblnhp_detectonlystaticprops (1 by default), in which it detects only welded and frozen props.
- They are now more aggressive in attacking props so I suggest keeping wblnhp_detectonlystaticprops to 1.
- The new console command will now prevent npcs from randomly attacking loose props

*****************************************************************************


A Simple mod that will make npcs attack props (until it is destroyed) if it is in their way of their actual target. So barricading against npcs can actually be a thing! (Zombie Survival experience in Sandbox :3). Uses Simple Prop Damage - Ultimate Destruction and Destructable Doors

- NPCs will detect props in their way and shoot it, if it is in their way. (If they don't have any other path to you)
- Should work on most HL2 Basic NPCs not just zombies
- Barricade by freezing, weld, nail props and see them try to breach through!
- Should work on doors
- wblnhp_enablehatepropbreaching (1 by default) to enable/disable prop breaching
- wblnhp_detectdoors - for door detection
- wblnhp_detectonlystaticprops -- for detection of frozen/welded props

- Yes and No
- My Mod simply tells npcs to attack the props, and if props dont break it will make them attack it forever.
- So yes if you want all props to break and not make the npc attack a single prop forever.
- And No if by default the props theyll be attacking is already destructible. Or if you want them to play soccer with an indestructible prop, I wouldnt stop you hehe.

- Yes should work on them too, other npc bases might not work but i might add compatibility

- I highly suggest keeping wblnhp_detectonlystaticprops to 1 so they will only target frozen/welded props.
- unless you want them to attack the lose props for fun

And maybe try spawning in other people's duplicates and stay inside. Now you can really test if they're dupes are actually a safe shelter. :P
