Need a little help with coding for menu

[Conle]

By the way,this loop needs unrolling :

Code: [Select]

        for (int i=0; i<320; i+=back[b]->width)
            for (int j=0; j<240; j+=back[b]->height)
            {
            rdp_load_texture(0, 0, MIRROR_DISABLED, back[b]);
                rdp_draw_sprite(0, i, j);
                b=b+1;
            }

to

Code: [Select]

        for (int j=0; j<240; j+=back[b]->height)
        for (int i=0; i<320; i+=back[b]->width)
       {
            rdp_load_texture(0, 0, MIRROR_DISABLED, back[b++]);
            rdp_draw_sprite(0, i, j);
        }

Err - you didn't unroll it, you just flipped the order the tiles are drawn in. 

[Conle]

That!

Seems like I messed up while cutting the image in 80 pieces, stupid black line 

[Conle]

Don't edit manually each tile...Just store the background somewhere in rom or ram or psram and just do something like :

Code: [Select]

void upload_tiles(const unsigned char* buffer,int tileW,int tileH)
{
const char* end;
sprite_t* img = (sprite_t*)buffer;
const int blockSize = (tileW * tileH * img->bitdepth);

buffer += sizeof(sprite_t); //Skip lib dragon header

for(end = img->w * img->h * img->bitdepth - sizeof(sprite_t); buffer < end; buffer += blockSize)
{
img.data = buffer;
sync pipe
upload data
display data
}
}

Then you do :

Code: [Select]

upload_tiles(buffer,32,32); to fill the screen with 32x32 tiles.
 

ps - By the way , the image looks pretty good.Is it 32 or 16 bit? 
ps2 - forgot to tell you that of course you must calculate the offset of each tile.
Its extremely simple.You'll need a variable for X and Y axis. Then , while looping , you increase X axis equally to tileW.
When X axis reaches screen width , you increase the Y axis by tileH pixels and you set the x pointer back to offset 0.
 

Edit again - Anyway here's the code if you feel puzzled

Code: [Select]

void upload_tiles(const unsigned char* buffer,int tileW,int tileH)
{
   const char* end;
   int x,y;
   sprite_t* img = (sprite_t*)buffer;
   const int blockSize = (tileW * tileH * img->bitdepth);

   buffer += sizeof(sprite_t); //Skip lib dragon header

   for(x = y = 0,end = img->w * img->h * img->bitdepth - sizeof(sprite_t); buffer < end; buffer += blockSize)
   {
  if(x >= img->w)
  {
         x = 0;
         y += tileH;
      }

      img.data = buffer;
      sync pipe
      upload data
      display img , x , y

  x += tileW;
   }
}

Thats great, I will try that soon. That way changing the background would be a lot easier. 
The background is made with paint.net in 32bit, then sliced into 80 pieces, each saved as bmp and then batch converted to a 8Bit(256 Colors) png with Irfanview and finally with mksprite to a 16bit sprite. And TV is a 42" plasma. Picture made with Sony K750i mobile phone.

Anyway here the current state, it's not perfect but it's slowly progressing. 

[ChillyWilly]

That's coming along rather well. 

[Conle]

Indeed it looks really good.    The only thing i don't like is the font color for the entry list.Maybe pick a bit darker colors.

Thats great, I will try that soon. That way changing the background would be a lot easier.

Just don't forget to fix this line in the code i posted:

Code: [Select]

for(x = y = 0,end = img->w * img->h * img->bitdepth - sizeof(sprite_t); buffer < end; buffer += blockSize)

To

Code: [Select]

for(x = y = 0,end = buffer + (( img->w * img->h * img->bitdepth) - sizeof(sprite_t)); buffer < end; buffer += blockSize)

Because the offset must be relative to the buffer address.
I haven't tested the code(written it just off the top of my head) but the algorithm looks fine.

Is there anything better than Geany for programming on kubuntu?

[Conle]

Is there anything better than Geany for programming on kubuntu?

   There's nothing better than Gedit with oblivion theme.  (Edit-->I think it must be called Kedit on Kubuntu  )

Are you looking for something lighter, or heavier? Lighter - gedit. Heavier - Code Blocks or Eclipse.

[sanni]

Oh, I meant xubuntu of course, sorry

Thank you I will try gedit, I already did try Eclipse on Windows but that was too much.

[Conle]

Oh, I meant xubuntu of course, sorry

I believe that this is the purpose of those distros : to confuse us 
You've   lost the battle    , but not the war   

[madmonkey]

heavier: qt creator.
you don't need to use qt or qt project system to use it, and it's definitely convenient, but it's heavy

- What I need is, when I write as example:
rdp_load_texture(
Then it should tell me if rdp_load_texture returns an int or what and also what I have to put into the parentheses. Right now if allways have to search through all header files and look by myself.

- Also I need more colors.
It should color all different kind of keywords
Like if I write:
sprite_t *images[2] = {NULL, NULL};
Then sprite_t and such things e.g. int or so should be colored, because that all are those definition things that define what type it is. So if I see that color, I know, here something gets defined.
And then *images[2] should be in an color for arrays and so on.

And when I write:
if
{
    if
  {
  }
   else
 {
 }
}
Then the matching brackets  should be in the same color as the if but in an other color then other brackets and other ifs so I know this bracket belongs to that bracket and that if.

Also if I write it like this:
   else
 {
 {
I would notice it because the brackets would be of different color.

- And also I don't wanna type make in the shell. Because it just says look in line 745 you messed up. But it would be better if I could just compile from within the editor and it would highlight the lines in the editor so I don't have to search. Because I do allot of line searching.

- Also very important i would like some sort of  book mark function, where I can label bookmarks in the code for quick jumping to different parts of the code.
