How to have the first position of an object?

Hey, I want to know how can I have the first position of an object, because I'm making a football game, and you get more poit if you score far. So I don't know if it's possible to have only the first position of an actor.
?

if(this.getOneIntersectingObject(Goal.class) != null && this.getX() < 100){
         
            point = point + 5;
             
         
        }
         
               
        if(this.getOneIntersectingObject(Goal.class) != null && this.getX() < 300){
         
            point = point + 1;
             
         
        }

I cannot see where near or far is relevant here. If you are intersecting the goal, you would be just there, touching the goal. Give example with details of what you are trying to accomplish here.

https://prnt.sc/tjg9h5 This is a screenshot of my game, and if the player shoot at the +5 point, he receive, +5 point, if he shoot at the +3 point, he receive +3 point, and if he shoot at +1 point, he receive +1 point. But, the ball move and the getX() is not constant, so I don't know if it's possible to make it constant.

Have the ball assigned a "worth" value when kicked. Only use it if touches goal.

The getX() will always change with location of the ball. But you can take a 'snapshot' of getX() at a certain time by having some sort of interaction (touching the goal) or timer, and assign it to a variable. I don't quite get what you want to do, but to assign such a variable:

if(getOneIntersectingObject(Goal.class) != null)
        {
            int xAtTimeOfIntersectingGoal = getX();       
        }
Here you will simply get the x-location of the ball when it goes through a goal, meaning it will be the x-location of whichever goal it hits. If you want to keep that location and not have it update when hitting the next goal, you need to either have seperate goal classes or some sort of toggle to prevent xAtTimeOfIntersectingGoal from updating, such as:
?

boolean hasHitGoal = false;
 
if(getOneIntersectingObject(Goal.class) != null && hasHitGoal == false)
        {
            xAtTimeOfIntersectingGoal = getX();
            hasHitGoal = true;
        }
