The one prim Keypad

(Warning this only works on the Beta (Aditi) Grid, as of this posting, because it relies on Server version 1.24, coming *soon* ™ to a simulator near you)

Here is a simple one line function to use llDetectedTouchST()and return an integer value that would correspond to a key code on a keyboard matrix. I hope that it will simplify making one prim keypads.

//
//Very Keynes - August 2008
//Beta Grid only as of posting
//
// returns an interger value corresponding to a key matrix, nubered from left to
// right and from top to bottom, when the prim face is touched, in the format ccr,
// therefor a Hexgrid (4x4) will have the following key codes:
//
//  0   10  20  30
//  1   11  21  31
//  2   12  22  32
//  3   13  23  33
//

integer cols = 4; // set to number of columns in matrix
integer rows = 4; // Set to number of rows in matrix

integer keypad(vector loc)
    {return 10 * llFloor(loc.x * cols) + (rows - llFloor(loc.y * rows) - 1);}

default
{
    touch_start(integer total_number)
    {
        llOwnerSay((string)keypad(llDetectedTouchST(0)));
    }
}

p.s. It is not by accident that it returns the key code in the format used by Hewlett-Packard in their older calculators.

Oooh... interesting.

Thanks for posting this

Are you suggesting the developers team calculators are behind the times or that they pulled one apart to work out how to do this ?

Not at all , Rather that My favorite calculators are still the old HP's and that I pulled one apart to do this .
Seriously, I disassembled the ROM so that I could make an emulator. And am still considering using its BCD Math functions in place of the built in Ansi float.

Be warned that only people running the corresponding new viewer will able to take advantage of this. You may want to add a feature whereby invalid touch values result in a dialogue coming up instead for people on 1.19 or even older viewers?

[edit]I don't mean the OP since the script is just an example, but anyone intending to take advantage of this.
