About Me

Hi I'm Darwin Recreant. I reside in Israel and has been enjoying Second Life since March 2007. I co-own the College of Scripting Music and Science along with Keystoner March and Shera Beam. I'm an advanced scripter and currently open for any large project offers. I also give private lessons on scripting.

Feel free to contact me in-world.

My Scripts

Find Screen Width

The script below will give the width of the screen in meters by touching anywhere on the visible face, given that the prim is a box with zero rotation and attached at one of the corner HUD attachment points. <lsl>default {

   touch_start(integer total_number)
   {
       vector scale = llGetScale();
       vector off_point = llGetLocalPos();
       vector face_pos = llDetectedTouchST(0);
       vector screen_pos = llDetectedTouchPos(0);
       
       float screen_width = ((face_pos.x-.5)*scale.y-off_point.y+screen_pos.y)*2;
       
       llOwnerSay((string)screen_width);
   }

}</lsl>

Color Picker

Script that converts hue/sat/lum to red/green/blue based on texture coordinates on a single prim and outputs the vector rgb.

Prim Setup

<lsl>default {

   state_entry()
   {
       llSetPrimitiveParams([
           PRIM_SIZE, <.5,.4,.1>, 
           PRIM_TYPE, PRIM_TYPE_BOX, PRIM_HOLE_SQUARE, <0,1,0>, 0.0, <0,0,0>, <.8,1,0>, <.02,0,0>, 
           PRIM_TEXTURE, ALL_SIDES, (key)"5748decc-f629-461c-9a36-a35a221fe21f", <1,1,0>, <0,0,0>, 0.0, 
           PRIM_TEXTURE, 0, (key)"404e4461-8a22-fbf7-7652-4b81dc7da325", <1,1,0>, <0,0,0>, 0.0,

UV Button Maker

The following scripts are tools to making your own uv button setup for a texture in a hud or for any multi-button texture. First script is for getting the button coordinates which are used in the second script (detected_button) which returns the button number pressed.

Get Coordinates

<lsl>integer start_face; vector start_uv;

default {

  touch_start(integer s)
  {
      start_face = llDetectedTouchFace(0);
      start_uv = llDetectedTouchUV(0);
      start_uv.x += -(integer)start_uv.x - (start_uv.x < 0);
      start_uv.y += -(integer)start_uv.y - (start_uv.y < 0);
  }

  touch(integer s)
  {
     if(llDetectedTouchFace(0) == start_face)
     {
        vector new_uv = llDetectedTouchUV(0);
        new_uv.x -= (integer)new_uv.x - (new_uv.x < 0);
        new_uv.y -= (integer)new_uv.y - (new_uv.y < 0);

        llSetText((string)start_uv+"

Pass Code Dialog

A simple script that will receive number inputs through menu like a number pad, and will grant access when submission matches pass code <lsl>string pass_code = "1234"; string code_input;

integer dialog_ch; integer dialog_handle; key dialog_user;

list rebutton(list src) {

   temp += llList2List(src, -12, -10);
   
   return temp;
