2048 Clone

[__builtin]

For what it's worth, I recently made a clone of 2048 for Rockbox with colors, animations, optional undo, savegames, highscores... EVERYTHING!
If anyone would like to test it out, it is on Gerrit already: http://gerrit.rockbox.org/r/888.

The screendump is broken on iPod 6G (stack overflow on USB insert), so no shots, SO TRY IT YOURSELF!

I have tested it on c200v1, iPod Classic, and e200 in simulator.

Please keep any feedback constructive.

Screenshots are attached (from e200 sim)

Better screenshot is attached, again on e200 sim.

Font size has been increased to show responsive drawing.

Hi theunamedguy,

Thank you for your contribution.

A couple of things, I should (and likely will) post on the gerrit instance, that occurred to me.

Whitespace.

The patch is littered with whitespace that needs cleaning up.

Tiles.

If the plugin were to use bitmaps for the tiles, with some trivial changes it could scale to fit any arbitrary screen resolution, and open the door to greyscale and monochrome targets. This would increase the plugin size somewhat, but the bitmaps wouldn't need to be particularly large, or particularly complicated.

The tile bitmaps could then be scaled to 1/8th (for an 8x8 grid) of the smaller of the two values of the target screen resolution. So, for example, if the target device resolution is 240x320, the tiles would be scaled to (240÷8=) 30px square and stacked side by side in an 8x8 grid.

This would also allow for "pretty" tiles. Perhaps incorporating a border for the tiles, or nice rounded edges.

Once again, thank you for your contribution.

I have fixed the whitespace and indentation.

When you say an 8x8 grid, do you mean a 4x4 grid? Maybe a 5x5 grid to leave the top row open for the title/score?

I made the following table for convenience:

Table:

Screen Size             Tile Size
240x320	48x48
220x176	36x36
176x132	26x26
160x128	26x26
176x132	26x26
128x128	26x26
132x110	22x22
112x64	12x12

Rewrote the drawing to use bitmaps, quite bug-free now.

Some things to do before upload:
 - Draw the background (not the tiles, the grid) (maybe)
 - Draw the text at the top. (must)
 - Make corners rounder (maybe)
 - Make tiles glow (maybe)
 - Fix compatibility issues (fall back to text-based drawing if no bitmap support)

Has been tested on e200 in sim and ipod6g on hardware.

Should be ready for upload within a few days.
EDIT: Has been uploaded to Gerrit for review.

When you say an 8x8 grid, do you mean a 4x4 grid?

I do indeed, yes.

Apparently I couldn't count yesterday.

Regarding the tiles themselves, are they pre-rendered at a fixed size, or being scaled on demand?

It looks really good, by the way. The only immediately obvious thing left to tackle would be making sure the tiles/board is centred in the display (this may be negated if the tiles were scaled to suit the resolution on demand).

They are pre-scaled for each target screen. The raw bitmap is available at http://fwei.tk/2048tiles.bmp.

There is the problem of tiles over 2048. According to http://www.quora.com/What-is-your-highest-tile-in-2048, the highest possible tile is 131072 on a 4x4 grid. That's 17 tiles I need to make bitmaps for. Is this overkill?

EDIT: All tiles up to 131072 have bitmaps for them now.

Also, I am not sure how I should go about drawing the background. Should I use a bitmap? If so, what sizes would I need?

this may be negated if the tiles were scaled to suit the resolution on demand

How would I scale them on-demand? An API function?

To ease testing, I have written a very simple and BUGGY save editor for 2048.
With it, I have verified that the drawing is bug-free!

It is attached, but beware that it is BUGGY.
The commands are as follows:
c - change a tile
s - change the score
e - write to 2048.resume and exit
Run it in the .rockbox/rocks/games directory.

OK, much better now!
Some minor bugs have been fixed, and many new features have been added.
Screenshot attached, running on ipod6g sim.

Notice the NICE, ROUND corners. 

Only big thing left is to make sure it compiles on every target. Testers are needed!

[__builtin]

Patch set 36 resized the background to make it more like the real game. However, it might go outside of the screen on some targets. Therefore, testers are needed!
A best score box has been added, also.
Screenshot attached, enjoy! 

EDIT: Colors look messed up in screenshot because of lossy JPEG compression, it is not because of the plugin.

Kinda late, but this has been accepted into Git!
