How to save object's skin state, broadcast the skin change?

[gl0om]

Is it possible to broadcast event of changing object's skin? I mean clicking on lamp to switch the light on or off. It would be great to broadcast this event to other clients inside room. And also it'd be great to save lamp's state in database whether it turned on or off. And then load lamp's state for new avatars inside the room.

Of course this can't be an out-of-the-box feature, as everyone would need to broadcast something different, but you can do it on your own, by sending a message to the extension, save the state to the db and send an extension response to all the users on the same map, so that they can change the lamp state. Also, you will need to retrieve the current state from the db as soon as the map is rendered, and update the state of its objects accordingly.

What should I use as unique ID of our "lamp"? Does "ix" value from map's json data can be used as a key to store in db? I'm afraid that ix value may be changed after editing the map.

D0n't know what ix is. Anyway you can give the lamp an instance name, or use its map coordinates.

I don't know what ix is too, but I found it in json object during saving the map. It looks something like {"ix":131,"ii":"lamp2","i":"t54"}

Oh yes, that's the item position on the map, expressed as a single number instead of the x,y,z coordinates

Hey Bax -- How is that 'ix' value derived? From the px, py and pz values? How would I go about replicating that value on the client-side?

Thanks

Code: Select all

ix = px + (py * mapWidth) + (pz * mapWidth * mapHeight)

Great, thanks for the quick reply
