Triggering another npc in the level?

I know how to trigger different weapons but how would I trigger an npc in another npc in the same level. Like lets say there was a switch you had to to and it would then like open a door or something. Could anyone give me an example of how I could do it?

Well, if you know the x/y use triggeraction.

Here's the door

HTML Code:

function onCreated() {

  this.setShape(1, 32, 32);

  level.doorPosition = {this.x, this.y};

}



function onActionOpenDoor(player) {

  //The door has been opened

}

Here's the switch to open the door

HTML Code:

function onCreated() {

  this.setShape(1, 32, 32);

}



function onPlayerTouchsMe() {

    //Let's just send the trigger every 3 seconds, between another touch

  if (this.lastsend > timevar2) return;

  this.lastsend = timevar2 + 3;



  triggeraction(level.doorPosition[0], level.doorPosition[1], "OpenDoor", player);

}

You'll notice that I saved the doors position in a global level variable. Easier than finding out the right position of the object, where ever it's moved it'll be in that position.

It's probably better do do something like this:

PHP Code:


		
			
function onCreated() {
  level.door = this;
  this.hidden = false;
}
function onOpen() {
  if (! this.hidden) {
    return;
  }
  
  this.hidden = true;
  hide();
  scheduleevent(3, "Show");
}
function onShow() {
  this.hidden = false;
  show();
}

and then in the other script

PHP Code:


		
			
function onPlayerTouchsMe() {
  if (level.door.hidden) {
    return;
  }
  
  level.door.trigger("Open");
}

Notice I'm putting the actual NPC object in a level variable, not the x and y. This ensures that you'll always get to that NPC, even if there's another NPC on top of it, which could cause problems when using triggeraction.

Can you set level.lol clientside?
Edit:
Also can I use Andys XY triggeraction to trigger serverside in the same npc?

You are triggering serverside since it's a level npc. Level npcs trigger to the serverside to the function denoted by onActionFunctionName().

It isn't really a problem unless both NPCs have the same function name, but yes, probably better to rely on the object rather than an x/y position.

Well this is what I tried and I cannot get it to work, I have no clue what's wrong with it.

You haven't defined a shape for the object, you need a setShape() in the serverside.

Alright awesome thanks, it was the setshape that was giving me a problem because I wasn't aware that it was needed.

That's a good idea actually, yeah. I didn't think of that- thanks! :D

Same, I'll also remember that one.
