I have a general question about tooltips in UO:

is it possible only to display tooltips for items on the char and in the bagpack, but not for every item on the ground?

As far as I have tested it with another distro, disabling tooltip-sending leaves an empty grey tooltip on all items, which are movable.

so I ask myself, if it is a normal behaviour if AoS is enabled, that movable items show tooltips - I studied the packet guide now some time but I can't find where tooltips are activated.

I use the same client on different distros, and some display tooltips, some don't - with or without AoS enabling. So it has to be something which I didn't think of.

Any hints from some dev on the important packets for tooltips would be much appreciated.

Take a look at the megacliloc packet and the example in the scripts forum.
I use that to look up an itemedesc entry for a targetted object so that it can display anything you like.

do all your movable objects display some tooltips then?

or just those you selected?

_now_ I get it. Tooltips are on - or off.

So that means that every movable item is displaying a tooltip, if available or not.

That's quite a shame. I would have loved tooltips only in my bagpacks...

But it seems that's impossible...

Did some testing concerning this. I presumed that IF client asks for tooltip information and does not get replied, it would display nothing. Doing that it would be easy to 'emulate' default behaviour of printing text above the item. But, turns out I was wrong. If tooltip packet gets no reply, client displays item name fetched from its own files.

Thus I confirm that what you wanted might just be impossible.

my client 4.0.0c displays nothing then.
maybe thats just a later behaviour.

also, there is this toggler in the client where you can put the tooltip on a different location on the screen, which in endeffect solves the problem.
