Is there a way to define the repeat(){} method? I'm making a library for scratch users who want to learn java... it will be like Scratch (sorta).

I'm thinking this kind of code? (I'm still learning    )

Code:

static void repeat(int num) {
     for (int i = 0; i < num; i++) {
     }  
}

Um... that wouldn't actually do anything, other than go through a loop that does nothing num times.

@ProgrammingFreak: What's Snap? I can't say I've heard of it. 

Really? I think you would enjoy it. 
It's an online version of Scratch that Jens and bharvey are developing. 
Check it out here. Hope you enjoy. I've only played with it a little. 

Oh, interesting! From what I see... it's basically online BYOB?

(It's a library to make it easier to load graphics and stuff for use with openGL)

I know how you feel, man.

Sweet, i'd like to try it :3

Everyone interested stay tuned for the first Undercover Study Hall Release of ALLCAPSRAGE studios! it will be available as a .zip file with all necessary libraries, images, class files and .java source files.

ugh. Exporting this seems like a pan, maybe it will be tomorrow XD I hae about 10 more minutes to find a solution. PROTIP: Only announce something if you're sure it's gonna work. 

yep, it will probably be tomorrow first period. (any time between 8:00 CST and 9:25 CST) I COMPLETELY FORGOT about LWJGL's natives! Eclipse completely left them out!

does anyone know how to make something wait until a button is pressed?
ive tried making a loop raise a bogus variable (1) until a different variable (2) is a certain number

the button changes the other variable (2) by one but only if the variable (2) is 0

but it just gets unhappy and freezes and turns black

boolean mybuttonpressed = false
While(!mybuttonpressed){
}
public void keyPressed(KeyEvent ke)
{
    if(ke.keyText(ke.keyCode) == "space")
        mybuttonpressed = true;
}
sloppy and unterminatable but it works.

Code:

static void repeat(int num) {
     for (int i = 0; i < num; i++) {
     }  
}

it could be made simpler like this(using an anonymous inner class)

repeat(3, new code() {public void code() {
            
        }});

the repeat method:

public static void repeat(int num, code code){
    for (int i = 0; i < num; i++) {
        code.code();
    }
}

code.java

public interface code {

    public void code();
    
}

I successfully made a draggable easily editable scratch type block in java. 

I am happy to announce releasing Pong as my first java game! You can read more on my Tumblr here. It's quite amazing that I've completed my first game exactly one month from my first compiled java project. If you look at the tumblr, I was able to compile on February 2nd and am releasing the finished product of all that work on February 29th!

Anyone know what I could use to make a GUI in java?

Use the javax.swing toolkit. Obviously that's a lot of classes, so here're some guides to hopefully help you along:

Oracle's Swing GUI guide
Thenewboston's tutorial You'll have to watch several videos - he uses quite a few to go over the basics. However, he's very good at explaining things in the simplest way possible if that's what you need.

Nice 16, that's great for a first game :3
