help getting object x - myPosition x

[skillerkidos1 66]

So I'm trying to get the X of an object in a instance and get my X while in that instance and then subtract them

@Override
public int onLoop() throws InterruptedException {
    RS2Object obj = getObjects().closest(123);



    int distance = myPosition().getX() - obj.getPosition().getX();
I also tried
    int distance = myPosition().getX() - obj.getX();

if(distance <= 2){

//do this

}

 

When I do either of those and start the script I get this error

[ERROR][Bot #1][01/14 07:34:39 PM]: Error in script executor!
java.lang.NullPointerException
    at main.onLoop(main.java:125)
    at org.osbot.rs07.event.ScriptExecutor$InternalExecutor.run(tk:46)
    at java.lang.Thread.run(Thread.java:748)

 

I'm not really sure what I'm doing wrong any help would be great

Thank you

omg do i just need to check if they are != null first?

@skillerkidos1 Pretty sure it's because something is null and you're not null checking anything. But disregarding that, does the distance api not work for what you're trying to do?

int distance = getMap().distance(obj.getPosition());

Always null check this kind of stuff before checking anything ^^
