Adding npcs in deathmatch?

I am currently working on a map in which i have a large pool of water under a bridge. i want to make the water basically a deathtrap so i would like to add certain npcs such as the ichthyosaur and the leeches to hurt anyone who falls in. can this be done for half life 2 deathmatch and how would i go about making them actually attack people who fall in.

try the entity trigger_waterydeath I found it in Hammer while looking through all the entities. According to the help in hammer it spawns leeches around the player and does damage until they die. Im not sure if this works in HL2DM though

or

you can try trigger_hurt

I dont think you can add npc's into multi player maps, even though they are in the entity list.

you can add the NPC's as a prop_static or Prop_dynamic then set thier default animation to somethng that makes it look like they are moving around. Other than that, no NPC in DM.

Some npc_ entities may still appear in deathmatch levels that you test on your PC, but I have a feeling that servers run with monsters turned off. Which means you can use a point_servercommand entity to turn them on again with the relevant command :smile:

I tried out the watery death entity and amazingly it works. Its so funny when people fall in the water and are freaking out trying to look for a way out before they are eaten alive. anyway i still have yet to get the npcs to "work" in hl2 dm. i can see them but they do not move or do anything for that matter. i do see the one server entity suggested to turn "on" monsters but i dont know what input or output i would put in, in order to actually enable them. if anybody knows how to enable them with the server entity or another way of adding WORKING npcs that would be great.
