lol? Atleast put it in code tags and post the error your getting?

[zla7ko0o]

Done i don`t get error

[namelessgnome]

hm...

at the top of the recall port function add a check to see if we are in combat (m_session->GetPlayer()...) if we are in combat just return and broadcast a message to them using the session object..

[zla7ko0o]

Post fully code please

[namelessgnome]

First of all I never actually coded that thing.

And IMO the only way to learn is to do it your self. There are many, many examples of what explained to you. You can find them in almost any teleporter script.

I tried if can i would`t post it .. So s.b help please
