Scripting Array

Same puzzle pub for Opus Pro 9.

To save on using multiple standard actions, in this case rotating back to 0 angle each of 36 puzzle pieces (F1-F36) so they are essentially reset.

How to script an array for F1-F36 and set each's display data angle to 0? Currently using 36 standard actions. Since several buttons with these 36 standard actions, pub becoming slow.

Tried the following based on previous example by Mack, but this time, couldn't get it to work for this rotation:

Code:

function chooser200(len2, sub2)
{
   var a  =new Array;
      for (var i=0;i<len2;i++) //generate numbers
      a[i] = i+1
      eval("F"+a[i] +".SetRotation(0,true,1.0)")

}

//chooser200(36,36)

So, I must be doing something wrong.

Again, must be a more efficient (and correct) way to do this using script.

Code:

function doReset(len) {
   for (var i=1;i<=len;i++) 
      eval("F"+i+".SetRotation(0,0,0,0)");

}

FYI: Given the bigger picture, it would be better to use OOP rather than eval() all the time. This would involve assigning the host objects (IE Frames) to a variable or array element - and allow them to be manipulated directly. The attached example shows how to do that - and you can then apply the same for loops for randomising / reset directly on the object rather than having to resort to eval.

FYI2: Eval doesn't have a great reputation. It's one of those commands, that is best used with a pinch of salt and with an understanding that there is normally, a better, if not more advanced solution to solve the problem.

Thank you, Mack.

Yes, avoiding overuse of the eval function is a good idea.

So, this substitute works:

Code:

function doReset(len) {
var pieces10 = new Array(F1,F2,F3,F4,F5,F6,F7,F8,F9,F10,F11,F12,F13,F14,F15,F16,F17,F18,F19,F20,F21,F22,F23,F24,F25,F26,F27,F28,F29,F30,F31,F32,F33,F34,F35,F36); 
   for (var i = 0;i < len;i++)
      pieces10[i].SetRotation(0,0,0,0);
}
