With compression, around 42kB or so, perfectly for an appvar

120kB if uncompressed
How is it possible?

Ehm, I have a 255x100 sprite

Progress so far:

- Rendering of all the buildings is ready, I only need to add one thing, and that is when the building is entirely offscreen, it would skip the decompression + displaying part, to save speed.
- Resources (Wood, food, gold, stone) + population/max population at the top of the screen.



The crash at the end only happened special for this screenshot.

Oh, and my lil' bro said the lumbercamp and the miningcamp are 2x2 tiles, so I need to change that.

EDIT:

I did a clash of clans like only in offline, about a month ago, but I abandoned
Good job PT_
I wait the alpha

You should rename it to "Âge of Eripmec" to avoid copyright infringment

You are playing Oiram, right? I will try to find something about that copyright stuff

The last screenshot I posted was about 2 FPS (it took 20 million clock cycles), but I made some changes which speeds it up. First of all, I've decreased all buildings to 50%, to see more buildings at the screen. This lifts the FPS up to about 9. Next, I heard Runer112 and Mateo are writing a new TransparentSprite routine, which could lead to an FPS of maybe 20 or even more. But while that routine is not available yet, TheMachine02 decided to write a special routine for me, which displays only the isometric tile, not the transparent corners. The unclipped version was about 7 times faster than the clipped TransparentSprite routine, but he needs to add clipping to it, so I don't know how much faster it would be. My last point is that I'm now going to write a routine to display only a part of the tilemap. My current routine is just 2 For-loops, but that is bad, because with large maps 90% of the tiles will be entirely offscreen, so if my routine just stops with drawing if the tiles are offscreen, I could save a lot of time, which lifts the FPS again up!

Good news: I found this thread: http://www.java-gaming.org/index.php?topic=24922.0 which explains pretty well how to draw only a part of the isometric tilemap, and hopefully it is enough to speed it up a lot

Have you made it with the online project builder ?

No, as it is now writting in ASM

'Long' time no update, I was pretty busy with exams and stuff, but I picked it up again, now that I have some more free time, and decided to implement the algorithm I already mentioned before. But the problem is that that algorithm doesn't work fine, and I don't know how to quickly solve it

The algorithm is basically like this:


with this code:

Code: Select all

{...}
        boolean nBump = false, mBump = false;
        int n = 1, nStart = 1, nBuffer = 1;
        int m = 1, mStart = 1, mBuffer = 1;

        for (int i = iStart; i < iMax; i++) {

            // Testing Purposes
            // Sleep 1 second each i iteration and paint the screen
            // TODO
            // .......


            for (int j = jStart - n; j < jStart + m; j++) {
                // paint the column
                colArray[ hWrap(i)][ vWrap(j)].paintAll(g);
            }
            // adjust m and n to keep us within the screen

            // adjust n
            if (!nBump) {
                //we have not yet reached the lowest j point
                // increment n to go even lower next iteration
                n++;
                // Check if we have reached the lowest j point
                if ((jStart - n) == jMin) {
                    nBump = true;
                    //System.out.println("Bump N");
                }
            } else {
                // we have reached the deepest j and are now going back
                // start decreasing after the buffer is gone
                if (nBuffer > 0) {
                    nBuffer--;
                } else {
                    // The buffer is gone, start decreasing n each iteration
                    n--;
                    // check that n never exceeds its starting point
                    if (n < nStart) {
                        n = nStart;
                    }
                }
            }

            // adjust m
            if (!mBump) {
                // we have not yet reached the HIGHEST j point
                // increasee m to go even higher next iteration
                m++;
                // Check if we have reached the highest j point
                if ((jStart + m) == jMax) {
                    mBump = true;
                    //System.out.println("Bump M");
                }
            } else {
                // we have reached the maximum j point
                // and are now moving back.
                // start decreasing m after the buffer is gone
                if (mBuffer > 0) {
                    mBuffer--;
                } else {
                    // The Buffer is gone
                    // decrease m each iteration
                    m--;
                    // check that m never exceeds its starting point
                    if (m < mStart) {
                        m = mStart;
                    }
                }
            }
        }
    }
}

But if I do almost the same steps in my own tilemap, I get this:

(I assume now that the blue rectangle is the visible screen)

The orange line is how it should be, but the yellow line is the outcome of the algorithm.. Anybode that can help me out?

EDIT: 1 minute after posting, I got the solution... I need to change nBuffer to be not 1, but the amount of tiles that can fit horizontally in the screen... Sorry for disturbing you

Got a non-working homescreen done!
