3den event handlers

[pierremgi 4737]

Hi all,

I'm trying to detect some change on attributes of entities in 3den (position rotation or else, of a unit)

 

I tried

add3DENEventHandler ["AttributesChanged3DEN", {
 params ["_object"];
systemChat str _object
}];

in debug console. That doesn't work or I miss something.

 

For general purpose, anyone knows how to make add3denEventHandler work?  (console seems to fail whatever the 3denEH. It returns -1 and nothing occurs).

Thanks

How did you define the object you attached the EH to?
Because naming the object and using the name in the console in Eden does not work. You need to for example select the unit and then use :
 

(get3DENSelected "object" select 0) add3DENEventHandler ["AttributesChanged3DEN", {
    params ["_object"];
    systemChat str _object
}]; 

The eh will fire after the rotation or whatever is done, not when it starts or during it.

EDIT:
And obviously eden ehs only work in eden

I didn't name any object and didn't apply to any object. I tried to change attributes on several objects, waiting for some result, as I thought this EH was a "generic" EH like MissionEventHandler.

There is no object mentioned as param in documentation:

Thanks

attributesChanged3DEN is object EH not editor EH, and it says so right on the page you linked

Yes there is, attributesChanged3DEN is object EH not editor EH, and it says so right on the page you linked if you bothered to read it.

I did, indeed, and I disagree with your sarcasm. I persist the BIKI page example 1 (and unique) is not clear at all in regard of usual pages, for usual reader.

You should take some holidays. At least, do not answer anymore to my post. This one could be closed after H - answer.

Many thanks to @h - with constructive helpful answer.

I wasn’t being sarcastic. This is quote from that page:

 

Object Event Handlers

Editor specific event handlers can be also added directly to objects, using addEventHandler command.

 

And the EH you were trying to add is listed right under.

@h -    Sorry, but I failed to make it work.

 @Lou Montana  Thanks for your change in BIKI. I'm sure that will help.

 

 

Now, I placed one player and 2 VR entities in 3den. Then, in debug console:

 

removeAll3DENEventHandlers "AttributesChanged3DEN";
systemChat "ready";
(get3DENSelected "object" select 0) add3DENEventHandler ["AttributesChanged3DEN", {
  params ["_object"];
  systemChat str _object;
}];

The console returns the entity and a msg error:

 7:50:56 Error in expression <y";
(get3DENSelected "object" select 0) add3DENEventHandler ["AttributesChanged3>
 7:50:56   Error position: <add3DENEventHandler ["AttributesChanged3>
 7:50:56   Error Missing ;

 

I tried also with :

((all3DENEntities select 0) select {_x isKindOf "B_Soldier_VR_F"} select 0). Of course, I verified this code returns a unit > I can find it in a watch line

 

So it's not a question of 3den unit selection/reference. That doesn't work.

Note: This page still doesn't help (as far as you can't see the word object or any other parameter). Beyond object, there is probably? some other limitation.

Thanks.

Oops, omitted to correct you on another matter:
add3DENEventhandler does not work on those object eventhandlers, you add them with regular addEventHandler, so should be:

(get3DENSelected "object" select 0) addEventHandler ["AttributesChanged3DEN", {
  params ["_object"];
  systemChat str _object;
}];

3DENEventhandlers are handlers for Eden actions like selecting some widget, saving a mission, undoing, deleting and so forth.
The line removeAll3DENEventHandlers "AttributesChanged3DEN"; is also incorrect because no such 3den eh exists.

One thing worth noting when fiddling with the Eden commands is that some of them report no errors even if you make one, and some of them CTD the game if you pass erroneous data.. Can't remember the CTD causing commands but usually if a command takes an entity as an argument, which in eden can be both a number (eden id) and an object, and you pass a null-object = ACCESS VIOLATION BLAHBLAHBLAH

The wrong info was an oversight on my behalf when filling examples some months ago; it is fixed now. Don't hesitate to mention Biki mistakes on the #community_wiki Arma 3 Discord channel!
