Checking numbers of items in a stack

[roguehippo]

hey there forums,

 

I was just wondering if it would be possible to check the amount of grounditems in a stack. like arrows on the ground. then pick them up if the stack is greater than a number. i tried :

 

GroundItem loot = getGroundItems().closest(g.item);

log("test1");

if(loot.getAmount() > 3 && (!inventory.isFull() || inventory.contains(g.item)))

{

log("test2 in if statement");

loot.interact("Take");

sleep(random(800,1000));

 

}

 --------

and the "loot.getamount() > 3" always made my code crash.

Null check

if(!inventory.isFull()){

if(loot.getAmount() > 3){

loot.interact("Take");

}

}

what do you mean by null check.

If(loot!=null){

what do you mean by null check.

That you should nullcheck pretty much everything before interacting with it.

If (thing != null) {

thing.doSomething;

}
