Checking for item in equipment slot

[Aviri]

I'm trying to see if my player has a ring of dueling in his equipment slot, but I am getting a NullPointerException.

Here is what I have so far, and it is not working.

if(!equipment.getItemInSlot(9).getName().startsWith("Ring of dueling")) {
				bank.withdraw(2552, 1); //withdraws ring of dueling(8)
			} else
					log("Already have a Ring of dueling.");

Does this work (if done correctly) if my bot currently has the bank open? Or do I have to tell it to open the eqiupment tab first, and then check if it has a ring or not?

 

Also, another thing I am having trouble with is using an inventory item on an object. Ex: Using a key on a door. How would I go about doing that?

 

Thanks for any help, in advance.

Try,

if(equipment.isWearingItem(EquipmentSlot.RING, "dueling"))
{

}

Because if they don't have anything equipped then Item would be null and then you'd be trying to call the .getName() method on a null object, hints the null pointer.

you are getting a npe when your checking the name of the item in slot 9. But you never did a null check on your item.

equipment.getItemInSlot(9) != null
//check name

when you first start a fresh client the bot has to check your equipment tab once. Ince that is done it can remember what tems you have on and dont need to close the bank.

Nope, getting a NullPointerException again. Note, this is with a ring of dueling equipted and without it equipted.

Also, I edited the bottom of my original post with another question, let me know if you can help.

Thank you!

Does the bot do this check automatically, or do I have to do that check within my script?

Thank you for your help!

Thanks for any help, in advance.

if (!getInventory().isItemSelected()) {
	getInventory().getItem("steel bar").interact("Use");
	sleep(gRandom(400, 100));
} else {	
	if (getInventory().getSelectedItemName().equalsIgnoreCase("steel bar")) {
		getObjects().closest(FURN).interact("Smelt", "Use");
		sleep(gRandom(700, 100));
	}

on its own, but if you can do it too by easily opening setting tab

Alright, last error I am getting:

The method closest(Filter<RS2Object>...) in the type EntityAPI<RS2Object> is not applicable for the arguments (RS2Object)

RS2Object DOOR = objects.closest("Door");

getObjects().closest(DOOR).interact("Open", "Use");

I assume I am initializing DOOR incorrect to work with the closest method, but not too sure how to go about fixing it.

objects.closest is the same thing as getObjects().closest so basically what you're doing now is getObjects().closest(objects.closest("Door"))

Also, the return value of objects.closest can be null so you should check for that before calling interact

Welp, didn't even realize that. Thanks for getting me there, and the helpful tip
