11:12 kilbith    is there any way to get a ServerActiveObject starting from a ISceneNode?
11:31 celeron55  no because ISceneNode is a client-side thing and ServerActiveObject is a server-side thing
11:33 kilbith    I know but I imagined that we could get an ID from ISceneNode and use it from ServerActiveObject
11:34 kilbith    or there's another way?
11:55 kilbith    something like: get the ISceneNode's ID -> get an ActiveObject from the server environment
11:55 kilbith    or there's no relationship at all possible?
12:58 kilbith    success: http://codepad.org/9ADd1x70
12:59 kilbith    `cam->getSelectedNodeID()` is the ISceneNode's ID
13:07 kilbith    looks like I've been lucky and getActiveObject actually expects a peer's ID
13:32 kilbith    Krock: you did talk about shared IDs between client/server, can you tell me more?
13:54 Krock      kilbith: the server has to update the CAO's position somehow, right? so there's an ID that must match
13:56 Krock      ClientEnvironment::addActiveObject  is what you need to check. there's an "id" parameter which originates from the server
13:57 kilbith    so I've got this: https://www.youtube.com/watch?v=DsGd1X9RlOE
13:57 Krock      however, the smoke puff is a bit special. it doesn't have a server ID
13:57 kilbith    the scene node (= the player) is picked through a raycast made up from the screen coordinates of a mouse click (note: irrlicht modification necessary)
13:57 Krock      what if it's a touch screen? they could point anywhere
13:57 kilbith    so basically (in gaming terms) you can left-click a player to select it, right-click to select a position on the map and the player would move to this target (exactly like in a RTS game)
13:58 kilbith    I'm not handling touch screen (and won't)
13:58 rubenwardy Touchscreen fakes a mouse click
13:58 Krock      rubenwardy: but I believe the selection raycast differs
13:59 rubenwardy By faking a mouse click
13:59 rubenwardy Basically, it sets the position to where the user taps and emits an event
13:59 Krock      oh right. the desktop cursor is centered too, so that's at least consistent
13:59 rubenwardy The selection raycast differs because the "mouse" position isn't necessarily centered
14:00 rubenwardy Also, remember that we support touchscreen on desktop too
14:01 rubenwardy Not that you'd want to use it
14:01 rubenwardy Also, I imagine with a camera API you might allow unlocking the mouse on desktop too
14:19 kilbith    Krock: I'm thinking of another way around
14:19 kilbith    https://github.com/minetest/minetest/blob/master/src/client/content_cao.cpp#L769
14:19 kilbith    all CAO are init with an of -1 (the third param (the ID) is always ignored)
14:20 kilbith    * with an ID of -1
14:20 kilbith    so the idea is to add a 3rd param with the peer_id
14:20 kilbith    so I can get a peer ID from any ISceneNode
14:27 kilbith    do note that the raycast only can get a ISceneNode since it's in irrlicht
14:57 kilbith    so the 3rd param is actually `m_id` and it does work
17:16 celeron55  https://github.com/minetest/minetest/pull/12690
17:16 celeron55  i'd like someone to test and confirm that this performs reasonably now
17:17 celeron55  i'll clean it up a bit once it does
