[Update] Possession Sphere

12/09/2025 - DeVloek:
- Rewrote the ACS and most of the DECORATE from scratch in Zscript
- The ghost no longer targets barrels and now passes through them
- The ghost is no longer destroyed when hitting surfaces, instead it bounces off and is destroyed after 20 seconds
- Improved seeker code, now the ghost seeks new targets when the current target is already possessed or shouldn't be affected otherwise 
- Slightly increased the ghost's speed, homing range and turn angle
- Added a "maxcharges" property to the ghost. Now it can continue seeking out monsters to possess until all charges are used
- Added an "allowbosses" property to the ghost, this determines if monsters with the BOSS flag should be affected or not
- Added dynamic possession duration based on monster health (can be toggled off so the original 45s duration is used for all monsters)
- Monsters now always play their SeeSound when aquiring new targets after being possessed or waking up from possession.
- The possession indicators are now particles instead of actors
- Added dynamic lights to the ghost projectile and possessed monsters
- Adjusted ghost sprite offsets to make it look less jittery when flying
- PNGcrushed sprites
- Added MAPINFO with a DoomEdNum

Update pending
I added an extra check for time freeze effects:

As the original author of this, I object.

I prefer to handle my own submissions myself. Also, as the update went beyond converting code to ZScript and re-packaging the thing as a pk3, I should've been contacted for permission.

My apologies, I thought it would've been okay since it's generally keeping the funtion similar. I'm guessing the update is being pulled? Also, for the PK3 and ZScript conversions, should I leave it or just leave yours?

I don't know what other people's policy about their submissions is. For myself, unless I say otherwise or give explicit permission for modification, my submissions are off limits.

I'm in no position to answer the other questions since I don't maintain the repository anymore.
