Removing an image entity

Postby s4eed » Tue May 13, 2014 8:51 am

Hello dear friends.
I add an image entity to my map using this code :

Code: Select all

   var i = new RImageEntity(
          new RImageData("scripts/MyScripts/tick.png",
                     new RVector(0,0),
                     new RVector(1,0),
                     new RVector(0,1),
                     50, 50, 0)

   TickImageEntites[entId] = i;

Suppose that entId is a unique key associated to each ImageEntity and TickImageEntites is something like this :

Code: Select all

var TickImageEntites = {};

Then I want to remove all of this image entities inside TickImageEntites using this code :

Code: Select all

      for (var k in TickImageEntites) {
         QMessageBox.information(0,"msg", "id:"+k);
         var op = new RDeleteObjectOperation(TickImageEntites[k], false);

But my code doesn't work at all! What the problem. thanks.

You might want to print TickImageEntites[k] in your for loop, to check if these are valid entities with a valid ID, etc.
