removing drawn objects

[Alan2004]

There was a thread some time back that discussed in detail the overhead associated with drawn objects and the removal of them after a specified number had been drawn and the thread included efs code showing how to do this. Does anyone remember which thread it was? I have searched using draw and still can not find it.

I don't recall the thread, but your answer is below.

First, you have to determine how many different "drawn objects" you want to control. Lets assume you have (1) lines and (2) shapes.

If you wanted to control these AS ONE, then you only need one resetting draw variable (as shown below). If you want to control these uniquely, then you need two (one for each item).

var GraphID1 = 0;
var GraphID2 = 0;

function main() {

// Limit of only 100 items drawn at any given time.

   fIncrementID1(100);  // increments/removes drawn item
           drawShapeRelative(0, high(0),  Shape.DIAMOND, "", Color.re, Shape.TOP | Shape.ONTOP , GraphID1+"SE");

   fIncrementID2(100);  // increments/removes drawn item
           drawShapeRelative(0, low(0),  Shape.DIAMOND, "", Color.green, Shape.TOP | Shape.ONTOP , GraphID2+"LE");
    


}

function fIncrementID1(DLimit) {
  GraphID1++;
  if (GraphID1 > DLimit) {
    GraphID1 = 0;
  }
}

function fIncrementID2(DLimit) {
  GraphID2++;
  if (GraphID2 > DLimit) {
    GraphID2 = 0;
  }
}
