Have a little idea I want to try out, but detecting when a player is standing on a teleporter exit (specifically, the Engineer who built the exit).

Not sure how to make this happen. Any good ideas? I know we can check if a player is on the ground or up against a wall (I've got an "up against a wall" check used in the TF2 Grenades plugin that I'm working on with my buddy), but I draw a blank when trying to figure out how to check if the player is standing on a teleporter exit.

SDKHooks' Touch hook?

Did it with traceray ... tested aswell.

Traceray may be too CPU expensive.

Touch events would be preferable, or a simple box hull compare.

[Pelipoika]

Just get the m_hGroundEntity and check if it's a teleporter

[friagram]

There is a netprop to tell you if it is an entrance/exit, or you can use getbuildingtype

You wouldnt notice any of the 'expensive' CPU usage, as i use traces a crap ton, and don't notice (almost 5 traces a player once with 26 players in a server.)

Oh wow, this seems perfect....Also, I may as well come clean: The idea is an Engineer "Jump Pad" based off of a YouTube video I saw where a player builds a teleporter entrance/exit and a minisentry, then has a medic heal them while they get shot at by the sentry, then something happens and they get launched.

With this however, it'll be a command that you use while standing on a teleporter and it'll launch you in the direction you are facing.

Do you have any idea how often the game uses traces anyways?
Like every time you fire a hitscan weapon, every pellet is tracerayd. It's fairly cheap.
I'v got plugins that fire this 10 times a second per client, it's fine.

Even with rapid fire using scatterguns and miniguns, the server is ok.

i forgot to mention that the traces i was performing was on a Prethink of each client.
