There should be a smarter way of blocking the ghost

[DESTROYGIRL]

Currently in OG and Rebuild, the only (simple) way of blocking a ghost into an area is by using a ghost clip, which is just a vphysics clip with a filter. This only stops the ghost from passing through when dropped. If the player is holding the ghost it will pass through without an issue.

The issue is with this is that players can fall to their deaths with the ghost held, and therefore the ghost can still get stuck out of bounds.
It also poses the problem that a clip is too restrictive. On Rise, there is no optimal way of clipping off the ghost that prevents it from being dropped off of the edge, allows it to be thrown down to lower levels, and also ensures it is still obtainable.

It's a complex issue that was briefly discussed here: https://discord.com/channels/1235346473827434517/1244281729036845200/1344244377345720401

for ghost clips you can just check if a player is intersecting that clip while having a ghost and just auto drop it as for the falling ghost thing just check the players last standing position something similar to how csgo does it on de_vertigo

We did talk about the last standing position solution, though people didn't seem certain on how we'd properly determine if that spot is safe to put the ghost back on, as the player might hit a walkable surface when falling down. I guess there's no silver bullet that works for every map, but we could make a brush entity that sends the ghost back to the last held position where the carrier is also touching the ground, but not if the player is within the volume of the entity, in which case it would be sent to the last time they were touching the ground before that.
We just need to make sure that when the ghost is teleported back it has motion disabled until it's picked up again. Or else it might start falling forever

easy if you have a navmesh you could use that but in any case you just check if player was FL_ONGROUND in the think function of the ghost and save the pos after that if you throw the ghost if it trouches a trigger for example we can make a trigger_ghost_reset it will reset the ghosts position to the last valid standing pos of the player

I commited to writing a doc for this, scheduled some time to do so on the evening of the 30th.
