Detecting position of click (rather than using multiple prims..)

I'm assuming if someone clicks on a prim you can't tell where on the prim the person clicked.

IE: the bingo cards could be one big texture instead of a zillion prims. You could just detect where people are clicking instead of detecting the link number and having that silly prim count.

Is this correct?

Yes. You can't get the location of a touch.

People have made some progress in using sensors and mouselook to fake this, but it's kind of complicated, paticularly when it comes to the vertical axis.

For something like bingo, it's not really practical anyway, as you need to be able to mark the card.

I assume you have a huge grid of 100 numbers and people have to pick 10 of them?

Random idea: have people drag a pin onto the board over the numbers they want to pick. Each pin will broadcast its position and ownername in a shout on_rez whic h allows the board to work out where the pins were placed.

That cuts down the number of prims by 90%.
