Hi all,
I'm now trying to make a game for nokia phones.
This game will be called Lines (in MADos is Formula 1)
the aim of this game that you need to go along in a map without reach the dark place or the end of screen.
Here is the rules: So the actual line will show your "speed and direction". There will be a box after the end of line. this box show where it will go if you press any number. BUT only 1 pixel is allowed to "accelerate or brake AND turn" so you have to be careful if you want to go along the map.
And here is a questions about nokix.
1st. Is it possible to check a graphich pixel in nokia lcd? I mean that if i print some picture to the screen Could i check that is the line on the already drawn pixel or not?
I can check if i use inside map (car_map[48][84]...) instead of graphich file but it takes more place in flash file.
thx any help
you probably wanted to say it takes more space in RAM, not flash file :).
so, there is no function like get_pixel() or something (but it's a good idea to add one in next snapshot :D) but you can check the pixel in some way...
you're probably using freegfx system, after opening the screen you can call following function:
UBYTE *freegfx_buffer(void);
this function returns a pointer to the screen data of your currently opened freegfx screen. The data are organised in the same way as all nokia bitmap data, i.e. every byte describes a COLUMN of 8 pixels, 84 bytes describe a 84x8 box, 6 such boxes describe whole screen, 84*48/8=84*6=504 bytes.
an example get_pixel() function could look like this:
BOOL get_pixel(UBYTE x, UBYTE y)
{
UBYTE *data=freegfx_buffer();
return (BOOL)((*(data+x+(84*(y/8)))>>y%8)&1);
}
Please remember that I haven't checked that routine.
Wish you good luck!

Really thanks your answer ;)
And i was right it takes more space in flash, because the map looks like this in my way. it just a sample map:
const unsigned char car_map[48][84] = {
"###########################################",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"#..................................................................................#",
"###########################################",
};
And this way really takes a lot of free space in flash :cry:
Thx again your help :)
Oh, I see now.
I've check that routine - it works. On friday there will be next scripts snapshot (last before I leave to rest somwhere in the sun for a month) and it will include this function with prototype:
BOOL freegfx_get_pixel(UBYTE x, UBYTE y);
It will be part of freegfx system.
Thanks for idea.

Sir Yak,
I have an other question:
Why is it that sometimes when i use freegfx some graphical command work properly for a time and after some keypress it doesn't? simply don't want to draw to the screen, while other work still properly
should i place a delay somewhere?
thx

Sorry for answering my question, but i found what was the problem.
It was my mistake :) i used two type for the same coordinate. :D
so there is no problem with freegfx

@ joci2000
new snapshot is available, it contains the freegfx_get_pixel() function.
