isometric tile setup

it helped but its still not perfect 😩 since its a 32x32 tile is it better to just write a function to round numbers up to the closest multiple of 32?

isometric tile setup

public void toIso(){
        int screenWidth = GamePanel.instance.getScreenWidth();
        int screenHeight = GamePanel.instance.getScreenHeight();
        
        int newX = (int) ((x-y)*0.66)+screenWidth/2;
        int newY = (int) ((x+y)*0.33)+screenHeight/3;
        x = newX;
        y = newY;
    }

public void toIso(){
        int screenWidth = GamePanel.instance.getScreenWidth();
        int screenHeight = GamePanel.instance.getScreenHeight();
        
        int newX = (int) ((x-y)*0.66)+screenWidth/2;
        int newY = (int) ((x+y)*0.33)+screenHeight/3;
        x = newX;
        y = newY;
    }

this is the new function but as u can see from the image the tiles arent perfectly aligned due to float multiplication. so instead of getting 48 i get 47 for example. is there a way to get the right value?

Filling array with same object reference

i did some debugging and found that all the PlayableEntities in the arraylist are same object instance, otherwise i cant really explain why the position of all characters is the one of the last offset

public void initializeCharacters(){
        initializeCharacter(party.get(0), new Vector2D(-20,-75));
        initializeCharacter(party.get(1), new Vector2D(20,-25));
        initializeCharacter(party.get(2), new Vector2D(-20,25));
        initializeCharacter(party.get(3), new Vector2D(20,75));

        System.out.println("current pos: "+party.get(0).pos);

public void initializeCharacters(){
        initializeCharacter(party.get(0), new Vector2D(-20,-75));
        initializeCharacter(party.get(1), new Vector2D(20,-25));
        initializeCharacter(party.get(2), new Vector2D(-20,25));
        initializeCharacter(party.get(3), new Vector2D(20,75));

        System.out.println("current pos: "+party.get(0).pos);

Filling array with same object reference

but i think the root of my issue is the fact that this

public static PlayableEntity getCharacter(Characters c,GamePanel gamePanel){
        if(c==Characters.PLAYER) return new PlayableEntity(gamePanel, "player",new Stats(100,20));
        else return null;
    }

public static PlayableEntity getCharacter(Characters c,GamePanel gamePanel){
        if(c==Characters.PLAYER) return new PlayableEntity(gamePanel, "player",new Stats(100,20));
        else return null;
    }

returns the same address each time, which i dont really understand why
