Thread: [need help] I have problem with game algorithm

diamonddash1.jpg
I want to create games like this. And now I can check nearly of block click by user.(I use algorithm name "Floodfill")
But when it disappear I can't check which block must fall replace that block.

If you don't understand my explanation. Please see the picture on top. when I click purple block at (1,2). It will be floodfill to block at (1,3).
And all of them will be disappear. BUT ! I can't coding to dismount the blue block add(1,1) to (1,3).

Ps. I come from country where don't use English is Official language.
If I use wrong word or wrong tense. Please provide me a correct word.

Thank you

How does the program store these objects? Post the code?

void floodfill(int x, int y, int color) {
int[] left = { x - 1, y };
int[] right = { x + 1, y };
int[] up = { x, y - 1 };
int[] down = { x, y + 1 };
past.add(new Point(x, y));
if (block[x][y].getColor() == color) {
past_temp.add(new Point(x, y));
count++;
if (left[0] != -1 && !isInList(left[0], left[1])) {
floodfill(left[0], left[1], color);
}
if (right[0] != 10 && !isInList(right[0], right[1])) {
floodfill(right[0], right[1], color);
}
if (up[1] != -1 && !isInList(up[0], up[1])) {
floodfill(up[0], up[1], color);
}
if (down[1] != 10 && !isInList(down[0], down[1])) {
floodfill(down[0], down[1], color);
}
}
}

I have Global arrayList to keep beside of block what user click (beside and same color).In this code it name "pastTemp"

Ps. The arrayList name "past" is build for keep block what I recursive to check. you can ignore them.

A two dimensional array would provide the access to the objects more suited to your needs:

[0,0] [0,1] [0,2] [0,3]
[1,0] [1,1] [1,2] [1,3]
[2,0] [2,1] [2,2] [2,3]
[3,0] [3,1] [3,2] [3,3]

With this you can easily move blocks side to side, or up and down
