Question by ninjaboynaru · Jul 18, 2013 at 06:07 PM · javascriptinventoryitemsfor loophow many

Get the number of items for loop returns

How would i get the number of objects/items that the for loop finds that have met the conditions.

Ammo is a class that extends the Item class

 var inv = new List.<Item>();
 function OnGUI(){
 for(ammo : Item in inv){
 switch(ammo.itemType){      //itemType is teh varible that represents the objEnum
 case objType.ammunition:    //objType is an enum inside the item class
 GUILayout,Button(ammo.icon);
 }
 }

}

How would I get or return the number of ammo whose itemType have met the condition in the for loop

...create an integer before the loop, set it to zero, and add one to it every time something meets your condition?
