Which would be an easy way(scripted) to start a thread (sound,anim,whatever..) if my ai reached a certain node?

info:
- i hit my ai-trigger and my ai goes to the defined node
- if the ai reached this node i want to play a sound for example or start another thread
- i tried several ways with targetnames or flags

There are a few way, lets start with scripting the movement and this is assuming you have basic knowledge or nodes and scripting.

Ok so scripted or not you will need to place goal node of your actor in the map so in radiant lets place a 'cover_crouch' or whatever one you need.

Between your actor and node you must obviously have a path set down.

Now your goal node needs a targetname, so with it selected hit 'N' type 'targetname' as the key and 'node1' as the value.

For this to work you will also have to have your ai set up for scripting, lets say you have cpt price in your map.

First you must grab the node.
price_node = getnode ("node1","targetname");

Now you must set the actor this node as a goal.
level.price setgoalnode(price_node);

Now waittill the actor reaches this node.
level.price waittill("goal");

To get this to work you can either use a trigger to call this in a seperate thread for each move, or add waittill("trigger"); commands where needed.

{
playertrig = getent("player_trig", "targetname");
playertrig waittill("trigger");
thread move1
}
move1
{
price_node = getnode ("node1","targetname");
level.price setgoalnode(price_node);
level.price waittill("goal");
}

thanks a lot rasta it works...i found a way and i just missed the idea to start the scripting from the player-ai-trigger...the trigger got a targetname now and i can handle the function on the ai-path via the script
