Is there a script that can make it so that a object attached to a avatar will only show if the avatar dose a certain gesture?

Set full alpha.
Get the animation key.
Set a timer event.
On the timer event, pull the animation list.
Check the animation key against the animation list.
Set visibility.
When the key can no longer be found, set alpha.

i dont really understand...lol
could you dumb it down
maybe step by step...

You need to take some scripting classes and read the scripting wiki. Once you do that, the above steps will become obvious to you.

Ok it may be obvious to some people but if you are totally new to scripting the wiki can be very confusing and a good cure for insomnia. I tried it and got hopelessly lost on all the side tracks i was sent down for each topic.

Remember not everyone has grown up with computer knowledge.
I personally find the syntax is not very intuitive.

If you can edit the gesture you could add a chat line like /1start and another with /1stop which get spoken at the start and end of the gesture, in the attachment it listens for these commands on channel 1 and then adjusts the alpha of the object accordingly.
