How do I make a horde rush at me when it spawns ?

Yeah, I made a L4D2 city freeroam map, but when a horde spawns it just stands op top of the buildings ! SI attack me hordes does not. How can I make them rush at me ?

NO I DON’T WANT TO TYPE NB_RUSH EVERY DAMN TIME A HORDE SPAWNS !

If you go in front of them, do they attack you?

Have you made the nav mesh? (I don’t know if this is needed for l4d2 or not, because I don’t have it) I remember hearing about instancing so I don’t know if you need to.

You need to set up the nav mesh correctly (as Firegod said).

You should to be able to make something out of this: http://developer.valvesoftware.com/wiki/L4D_Level_Design/Advanced_Nav_Editing

Use a logic_auto with nb_rush when the horde spawns?

Thank you, this is what I needed.

I had set up a Nav. But they still diden’t rush at me when spawned !

Thanks to all of you !

How do I do this exactly ?

A logic_auto is an entity that fires an output when the map is loaded, then deletes itself.

I assume nb_rush is an entity that makes a horde attack the player/s.

On the logic auto have "on map load (something like that) > name of nb_rush > spawn horde or something.
