Adding custom map to players inventory

Hi. I'm having a lot of trouble trying to add a map (item) with a custom image (from a folder in plugin directory) to a players inventory. I just have no idea how to combine it all and I would greatly appreciate some help. Would anyone be able to help me out?

Thank you!

 

This was taken straight from the Bukkit map api (http://wiki.sk89q.com/wiki/Bukkit_map_API) which you can use to do this more in depth but here is an example

Code:

//Register map listener
getServer().getPluginManager().registerEvent(Event.Type.MAP_INITIALIZE,
    new MapListener(), Priority.Normal, this);
//Map listener
public class MapListener {
    @Override
    public void onMapInitialize(MapInitializeEvent event) {
        if (event.getMapView().getId() == 1) {
            event.getMapView().registerVirtualBase(new NyanCatBase(), plugin);
            return;
        }
    }
}
//Base map renderer
import org.bukkit.maps.MapCanvas;
import org.bukkit.maps.MapPrintOrder;
import org.bukkit.maps.MapRenderer;
import org.bukkit.maps.MapView;
import com.sk89q.mapbook.Liquid.LiquidTest;
 
public class NyanCatBase implements MapRenderer {
    int inj = -1;
    int cont = 0;
 
    public void render(MapView map, MapCanvas canvas) {
        map.setRate(128);
        map.setPrintOrder(MapPrintOrder.Sequential);
 
        if ((cont++ % 60) != 0)
            return;
 
        inj++;
        BufferedImage img;
 
        try {
            img = ImageIO.read(new File("acertaincat_"
                    + (((inj) % 12) + 1) + ".png"));
        } catch (IOException e) {
            e.printStackTrace();
            return;
        }
 
        map.getDrawer().drawImage(img);
 
        return;
    }
 
    public void initialize(MapView map) {
    }
 
}

 

Hm... I've got two classes:

Code:java

 
package net.muosu.easyasabc;
 
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.server.MapInitializeEvent;
import org.bukkit.map.MapRenderer;
import org.bukkit.map.MapView;
 
public class MapRendererClass implements Listener {
    private EasyAsABC plugin;
    public MapRendererClass(EasyAsABC plugin) {
        this.plugin = plugin;
    }
 
    @EventHandler
    public void onMap(MapInitializeEvent event) {
        MapView map = event.getMap();
        for(MapRenderer renderer : map.getRenderers()) {
            map.removeRenderer(renderer);
            map.addRenderer(new a());
        }
    }
}
 

Code:java

 
package net.muosu.easyasabc;
 
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
 
import javax.imageio.ImageIO;
 
import org.bukkit.entity.Player;
import org.bukkit.map.MapCanvas;
import org.bukkit.map.MapRenderer;
import org.bukkit.map.MapView;
 
public class a extends MapRenderer {
 
    @Override
    public void render(MapView view, MapCanvas canvas, Player player) {
        try {
            canvas.drawImage(25, 25, ImageIO.read(new URL("[url]http://i57.tinypic.com/ofcbav.png[/url]")));
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}
 

It seems to print the image on the map fine but how can I use it onCommand? For example: player types /a and it prints the a class. If they type /b then it would print another class with a different image. Any idea?

 

candjxd There is no need to make your post all bold.

 

Here is an example i found.
i take no credit for this as it was just a forum post i found all credit goes to Cirno

Code:java

public class ImageRenderer extends MapRenderer {
 
    // So fancy.
    private SoftReference<BufferedImage> cacheImage;
    private boolean hasRendered = false;
 
    public ImageRenderer(String url) throws IOException {
        this.cacheImage = new SoftReference<BufferedImage>(this.getImage(url));
    }
 
    @SuppressWarnings("deprecation")
    @Override
    public void render(MapView view, MapCanvas canvas, Player player){
        if(this.hasRendered){
            return;
        }
 
        if(this.cacheImage.get() != null){
            canvas.drawImage(0, 0, this.cacheImage.get());
            this.hasRendered = true;
        }else{
            player.sendMessage(ChatColor.RED + "Attempted to render the image, but the cached image was null!");
            this.hasRendered = true;
        }
    }
 
    public BufferedImage getImage(String url) throws IOException{
        boolean useCache = ImageIO.getUseCache();
 
        // Temporarily disable cache, if it isn't already,
        // so we can get the latest image.
        ImageIO.setUseCache(false);
 
        BufferedImage image = resize(new URL(url), new Dimension(128,128));
        // TODO find import for RenderUtils
        //RenderUtils.resizeImage(image);
 
        // Renable it with the old value.
        ImageIO.setUseCache(useCache);
 
        return image;
    }
 
    public BufferedImage resize(final URL url, final Dimension size) throws IOException{
        final BufferedImage image = ImageIO.read(url);
        final BufferedImage resized = new BufferedImage(size.width, size.height, BufferedImage.TYPE_INT_ARGB);
        final Graphics2D g = resized.createGraphics();
        g.drawImage(image, 0, 0, size.width, size.height, null);
        g.dispose();
        return resized;
    }
 
}

Code:java

@Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        Player player = (Player) sender;
        if(args.length==1){
            MapView view = Bukkit.getMap(player.getItemInHand().getDurability());
            Iterator<MapRenderer> iter = view.getRenderers().iterator();
            while(iter.hasNext()){
                view.removeRenderer(iter.next());
            }
 
            try{
                ImageRenderer renderer = new ImageRenderer(args[0]);
                view.addRenderer(renderer);
                player.sendMessage(ChatColor.AQUA + "[ImgMap] Rendering " + args[0] + "!");
            }catch (IOException e){
                player.sendMessage(ChatColor.RED + "[ImgMap] An error occured! Is the URL correct?");
            }
            return true;
        }
        return false;
    }
 
}
