is there any way to check when a building has finished building?

"player_builtobject" is when you put the building down, and if you post hook it, that fires after you put it down
"player_upgradedobject" doesnt fire either once its done building, nor does OnEntityCreated (I wasnt sure if the model was replaced with another once it was finished playing its animation)

does anyone have any ideas?

You've a couple options:

IMO the best solution is to DHook CBaseObject::FinishedBuilding(). Offsets are 338 Linux and 336 Windows. There are a couple caveats with this, though. For example this'll fire if there is a Red Tape Recorder reversing the building. Also each time a building is upgraded. If you only want to hook it once, best bet is to Hook it OnEntityCreated/player_builtobject and remove the hook after the callback.

There are some netprops you could check every frame or so. When m_bBuilding true to false, then it has finished building. Also if m_flPercentageConstructed is >= 1.0, then it has also finished building.

Sentry's have a sentry_on_go_active event, so if you only need sentries then you can use that.

using Dhooks worked, thanks!
