So there's this one server where every round, it randomly generates props and removes prop to make some hiding location available and unavailable. I'm just wondering how this would be accomplished?

Would it require some point mapping on the level itself and use the plugin to detect those points?

If it's not something like ph_warehouse where the map handles all the prop generation, it's likely just a collection of manually-defined coordinates (and maybe pulling existing prop_* coordinates from the map).

Some other possibilities include sampling existing players' on-ground locations into a database for future candidate spawn points or leveraging TF2's navigation mesh generation and selecting points from there. Never heard of those actually being used in practice though.

Either that or it removes props randomly around the map, however I'm not sure how tf2 prophunt even works.

Oh, some maps does it by itself?

Yep. I just checked my copies of ph_maze_a4 and ph_warehouse_b1; both maps hook up a logic_auto's OnMultiNewRound output to toggle various hardcoded prop_dynamic entities.

Should be doable in SourceMod or even by dynamically injecting new props with Stripper:Source (each map's specific implementation of random prop spawning varies, so you'll have to dump each map's entities yourself, if they even set up random props at all).
