taking off a hat

I made an animation to take off a hat.

The hat needs to attach to the hand when the hand reaches the hat.
It needs to be put back after the greeting.

I have two problems: One is the timing, how can I trigger the attachment when the hand reaches the hat?
The other is that llAttachToAvatar needs permission, can that be done without the dialog ?
Can anyone explain how I could make this work ?

Thanks, Brendan

The toughest part of llAttachToAvatar is that the object needs to be rezzed in world before it does much. It doesn't provide for switching attachment points for an already worn object, I'm afraid.

To get the effect you want, it might work better to have two hats, one on the head and one in hand, and flip-flop llSetAlpha on the two after playing raise and lower animations. Aligning the attachments so it looks right will simply add to the fun of it all

Make it 2 animations. The first is the hand going to the hat. Attach the hat to the hand and start the second animation etc.....

Hmmm... Maybe a sheath type of scripting wouldn't be a bad idea...

You have 2 hats: an invisible one attached to hand, a visible one on head.

The hat in hand plays the anim that brings the hand to the hat, waits until completion, sends a chat message to hat on head and becomes visible. (Animation will have to be precise so that the 2 hats overlap.)

The hat on head becomes invisible and plays the anim to "take the hat off".

The chat delay and the fact that each hat plays one animation provides all the needed synchronization.

Since this is a hat and not a sword in sheath, switching visibility is easy:

llSetLinkAlpha(LINK_SET, isVisible, ALL_SIDES);

Putting the hat back on head is the same: Anim, switch visibility, anim to bring the hand away so that SL doesn't slam your arm back into whatever position it sees fit.

Thank you so much I am - Was having the same prob , and that would be the easyest fix for it . Dam thanks again :} So many smart people on here .

you can also shrink/expand/move the two alternatively so that the invisible parts aren't in the way/clickable

and shrinking and tucking away instead of setting alpha to 0 is better on render cost

not so much the alpha (if you're going to mess with textures they are still renedered then ignored with alpha, so swapping with plywood is better there, but probably not worth the effort)

Got some really cool ideas to play with now, thanks a bunch

to make sure the timing is correct between animations and hats changing between visible/invisible, i would probably use a gesture with chat commands telling the hats when it's worn or not worn because the gesture a built in wait, it can wait as many seconds as you tell it, or until the animation(s) are done
