Here's a great solution which encourage them to explore your store to receive the gifts. Visitors must walk around to search for the hunt box and they are automatically offered the gift when they come within one to two metres of it.
They also cannot get the same gift for two weeks so no massive grabbing of any transferable gifts.
This easy to use script is perfect not only for hunts but when you give out regular freebies from your store.
FEATURES
1.
Gift Giver says "Congratulations, here is the gift!" when it offers the gift to the hunter.
2.
Giver will give out gift only once to the same avatar during a two week period.
3.
If the hunter tries to get the gift before the two week period is up, Giver will say "Sorry, you have already received this gift

4.
If the hunter returns after the two week period, Giver will offer gift again and say "Welcome back, here is the gift again"
5.
To check how many gifts have been given by the boxes, stand next to the box and type Traffic Report in the open chat. A list of names will appear and you can copy for your own records. It is advisable to reset the script in the box after you have recorded the names.
LIMITATIONS
YOU MUST HAVE SCRIPTING ENABLED ON YOUR LAND FOR THIS TO WORK.
This script holds a maximum of approximately 200 avatar names/ visits. It will stop giving gifts when this has been reached. YOU MUST reset by clicking on the prim, and choosing Edit, Tools and Reset Scripts in Selection.
Please be aware this can happen very fast if you have several visits over a short period of time. I take no responsibility for the Gift Giver not giving out gifts due to any SL issues or if the script is not reset before the list of visits have reached its maximum.
By purchasing this script you accept all responsibility and liability of the functioning of the script.
