cant upload background images

[vladbuff]

I'm currently following Explv's tutorials on scripting and was following his paint tutorial and I was having issues when it came to uploading a background image. When i had the code in a normal script no background image would be uploaded but I wouldn't get any errors so to try and trouble shoot i created a script containing only the paint code to try and upload the background image but it wont even register as a script when i export it to the osbot script folder. I would really appreciate if someone can point out what I may be doing wrong. Using Eclipse IDE here's what i wrote: 

package core;

import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.IOException;
import javax.imageio.ImageIO;
import org.osbot.rs07.script.Script;

public class BackgroundTest extends Script {

BufferedImage background;

@Override
public void onStart() {

try {
background = ImageIO.read(BackgroundTest.class.getResourceAsStream("/resources/background.png")); 
} catch(IOException e) {
log(e);
}
}


@Override
public final int onLoop() throws InterruptedException {
// TODO Auto-generated method stub
return 0;
}


public void onPaint(Graphics2D g) {
if(background != null) {
g.drawImage(background, null, 300, 300);
}
}
}

okay that's huge i can actually launch the script now but it still doesn't draw an imagine onto the screen is there something else I need to do to actually get a background image to show up?

drawImage(Image img,
                   int x, int y,
                   ImageObserver observer);

It looks like you're inputting a null x coord, try doing 

 

g.drawImage(background, 300, 300, null);

this is a screenshot of where the resources folder is located and the image inside of it if that's relevant, i also looked at another thread with a seemingly similar problem where the solution was to verify that the image is getting exported correctly which it is

the img might need to be in the /osbot/data/ folder as well.

changing the x coords didnt seem to affect the outcome there isnt an image printing and i do have the same background.png saved in osbot/data/ unfortunately i might just try changing the image im trying to use as as a background image and see if that helps

Try something like this in you onStart to load an image and draw that image in your onPaint

public static File imageFile = new File(System.getProperty("user.home") + File.separator + "OSBot" + File.separator + "Data" + File.separator + "image.png");

try {
    BufferedImage image = ImageIO.read(imageFile);
} catch (IOException e) {
    e.printStackTrace();
}

alright so i commented out the old BufferedImage code and implemented this into my onstart method but it doesnt let me use the value of image in my onPaint method am i putting everything into the right spot of my code or do i need to change the typing on my onStart or onPaint from void to something else?

package core;

import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import org.osbot.rs07.script.Script;
import org.osbot.rs07.script.ScriptManifest;

@ScriptManifest(name = "BackgroundTest", author = "VladBuff", info = "", version = 0.1, logo = "")

public class BackgroundTest extends Script {
	
	//BufferedImage background;
	
	public static File imageFile = new File(System.getProperty("user.home") + File.separator + "OSBot" + File.separator + "Data" + File.separator + "background.png");

	@Override
	public void onStart() {
			
		try {
		    BufferedImage image = ImageIO.read(imageFile);
		} catch (IOException e) {
		    e.printStackTrace();
		}
	
		
		/*
		try {
			
			background = ImageIO.read(BackgroundTest.class.getResourceAsStream("/resources/background.png"));			
		} catch(IOException e) {
			log(e);
		}
		*/
		}
		 
	
	@Override
	public final int onLoop() throws InterruptedException {
		// TODO Auto-generated method stub
		return 0;
	}
		
		public void onPaint(Graphics2D g) {
			
			
		if(image != null) {
			g.drawImage(image, null, 0, 0);
			
		}
	}
				
}

You obviously have to put that variable outside the onStart to use it in the onPaint 
Just like u did with the background variable
