Question

Eclipse says I can’t make a static reference to the non-static field Art.instance. Why does it think I’m calling Art.instance from a static context?

TDRenderer itself gets called like so:

renderer = new TDRenderer();

TDRenderer.java:

package towerDefense;

import java.awt.Graphics;
import java.awt.Image;

public class TDRenderer {

    public Art art;

    public TDRenderer()
    {
        art = Art.instance;
    }

    public void render(Graphics g)
    {
        for(int i = 0; i < 32; i++)
        {
            for(int j = 0; j < 24; j++)
            {
                Image itd = (Image)(art.sprites[art.level1.tiles[i][j].type]);
                g.drawImage(itd, itd.getWidth(null), itd.getHeight(null), null);
            }
        }
    }
}

It’s not that you’re in a static context; it’s that instance is not a static field of Art, but referencing it as Art.instance means you’re trying to use it as if it were static.
