@Marcus, Orangy Tang,
I think you’re right, custom drawing routines are the way to go.
I join the comp if I may - most of my games look like they’re from the 80’s any way!
Will there be a parameter passed to the applet to say whether it should get focus and start playing sound? If we all use that then we could have all the apps on a single screen and playing nicely. Are there any devices (ie something like a chumby or a digital watch that could run these games when we’re finished or is it worth setting up a large pixelated projection screen and running them on that!

I think polling Component.isFocusOwner() or setting up a FocusListener with Component.addFocusListener(FocusListener) would do the trick.
We also need to detect loss of focus and stop hogging the CPU and turn off the sound. I was wondering whether we should free up any temporary data structures as well, in case we are sharing a virtual machine.
Another quick question: does the game have to be playable in 40*30 mode - I just tried my little idea for a game out and felt my eyes just weren’t good enough to play at that resolution. For those that are a bit slow on the Java side is there a list of colours that are ok - ie Color.blue etc.
I think x4 or x8 scaling of the basic 40x30 mode will be best. This is explained in the rules.
These standard java colours are also in the EGA colour palette.
public final static Color white = new Color(255, 255, 255);
public final static Color black = new Color(0, 0, 0);
public final static Color red = new Color(255, 0, 0);
public final static Color yellow = new Color(255, 255, 0);
public final static Color green = new Color(0, 255, 0);
public final static Color magenta = new Color(255, 0, 255);
public final static Color cyan = new Color(0, 255, 255);
public final static Color blue = new Color(0, 0, 255);
Of course you can define your own colours too.
Man, if people continue posting engines in the TinyGame Resources thread, and other sources in this thread… and if I get a crapton of luck… I might be able to make a game or something! :o
I donno, I’ve always loved restraints, but this is a bit over the top, limited resolution AND limited color… I’m going to try some of those EGA tests in the other thread and see if I can get something working. Don’t expect much yet. :S
Edit Yay! I got Notch’s Ega test running with little problems. I’m inclined to work off of his framework because it’s already applet-savvy.
Edit2 Got a tentative name, “Tiny Star Fighter”, or “TSF”. Writing a real simple keyboard poller class.
This is way too much fun. Rendering stuff at normal size, then shrinking it back and using dithering is really giving nice results. Thanks Markus for the idea. Now I gotta come up with a game…
I know I’m a little late here, but would you be so kind and post here the true-size version of this fonts ? (I mean not scaled up) ?
thanks
I encoded each of the characters in the lower 15 bits (3x5) of an int (starting at ASCII 28 for some reason I forgot):
private static final int[] FONT = new int[]{
0x0000,0x0000,0x0000,0x0000,0x0000,0x0000,0x0000,0x0000,0x0000,0x0000,
0x0000,0x0000,0x0000,0x0000,0x0000,0x0000,0x0000,0x0000,0x2000,0x17D9,
0x2B6A,0x749A,0x772A,0x38A3,0x49ED,0x39CF,0x2ACE,0x12A7,0x7BEF,0x39AA,
0x0410,0x1410,0x4454,0x0E38,0x1511,0x252A,0x0000,0x5BEA,0x3AEB,0x2A6A,
0x3B6B,0x72CF,0x12CF,0x2B4E,0x5BED,0x3497,0x5AED,0x7249,0x5B7D,0x5FFD,

0x24AD,0x72A7,0x0000,0x0000,0x0000,0x0000,0x0000,0x0000,0x0000,0x6B50,
0x3B59,0x6270,0x6B74,0x6750,0x25D6,0x3D50,0x5B59,0x2482,0x1482,0x5749,
0x2492,0x5BF8,0x5B50,0x2B50,0x1758,0x4D70,0x12C8,0x1450,0x24BA,0x2B68,

};
The least significant bit of each int is the top left pixel of the character, bit 15 is the bottom right pixel.
Here is the code I use for drawing:
public void drawString(String s, int x, int y, int color){
for(int i = 0; i < s.length(); i++){
int value = FONT[s.charAt(i) - 28];
for(int j = 0; j < 3*5; j++){
int px = x + j%3 + i*4;
int py = y + j/3;
if (((1 << j) & value) != 0 && px < WIDTH && py < HEIGHT && px >= 0 && py >= 0){
setPixel(px, py, color);
}
}
}
}
Is the letter misplacement in the array intentional, or is it unintended and caused only on my computer for some reason?

I could have included zeros in the FONT array for a 1-1 match with ascii so the
int value = FONT[s.charAt(i) - 28];
wouldn’t include the -28 I can’t remember why I didn’t it was probably to match up with a square texture grid or something.
Thanks for the answer, but I was asking because I had to tweak the array. Uppercase “I” was missing, and lowercase letters were off by one space. Thanks for the code too, I’m using it in my game and works flawlessly.
Your right, it is missing… I must have accidentally deleted it when formatting the code to fit in a forum post (was one line of source). Hex for ‘I’ is 0x7497.
