Libgdx Array<> How To Get Last Item?

I want to change Y position of 'bucket', when camera Y position is higher than 'last created bucket' Y position: There is my code in 'create()' method buckets = new Array

Solution 1:

You should try this,

if(cam.position.y > buckets.peek().getPosition().y){
     for(Bucket bucket : buckets){
        bucket.repos(rand.nextInt((int)W)/PPM,buckets.size+BUCKET_MARGIN/PPM);
    }
}

In this y position of buckets are not properly specified because according to your code all bucket set to particular y position.

EDIT

if(cam.position.y > buckets.peek().getPosition().y){
    for(Bucket bucket : buckets){
            bucket.repos(rand.nextInt((int)W)/PPM,cam.position.y+bucket.getPositon().y);
    }
}

EDIT 2

Take a look of this tutorial, I think it may be helpful for you.
