Paint. Hows does it work?

[Guest Apogee]

I know some of the API to display paint, but i really don't want JUST text on screen. IS there a way i can put an image i made on screen? (I know it is possible due to it being done on other scripts, i'm just unsure of how.) 

If you any of you know of a thread or section that has a guide or walkthrough of all of it, a link to that would be HIGHLY appreciated. Thanks

Welp it's pretty simple acutally. All you need is an Image, which you get from a URL.

 

You need to create 2 instance variables:

Image paintImg;
URL paintUrl;

then in your onStart do the following:

try {

paintUrl = new URL("yourPaint.com");

} catch (MalformedURLException e1) {

log("Problem loading URL.");

e1.printStackTrace();

}

try {

paintImg = ImageIO.read(paintUrl);

} catch (IOException e1) {

log("Problem loading image from URL.");

e1.printStackTrace();

}

Finally, paint it in your onPaint().

g.drawImage(paintImg, x, y, width,height,this);

what would "this" be?

"this" refers to your instance of your class. It means your main class will watch over the image.

 

Don't change it just keep it as "this". Also, make sure you add those changes I made to my post.

"this" refers to a parameter or a local variable that has the same name or is similar to another variable (I think)

 

// Global Variable

int Vara = 0;

 

public void DoThis(int Vara) {

this.Vara = Vara; // Grabs the parameter and sets it to the global variable

}

paintIMG and paintURL are both "wrong" according to eclipse. As far as i can tell, there's nothing to import.

Because you haven't done this... 

You need to import Image and URL...

import javax.imageio.ImageIO;
import java.net.URL;

Hmmm, I have those imports and i have created the instance variables. Does it matter where i declare them?

You can declare an instance variable anywhere after this:

public class MyScript extends Script {

uhmm simplest option would be to change "this" to null.

PERFECT. Can i rep you without actually doing a transaction with you? I went to rep and it was making me choose from buyer, or seller or something. :x
