Error loading two bitmap files in same program.

[pls]

Hi,

    I created two bitmap files for a small space shooting game. One is space ships etc called space.h. The other is a rotating meteor called meteor_assets.h. When I install the two included files I get an error message. When used separately they both work. 

    It appears that the variable ASSETS_END is defined in both of the include files. How do I combine the two files?

 I attached the three files for the game.

    See error messages below:

All,

    Not finding a method to combine the my 2 bitmap files into one, I decided to use brute force. I made one file with all the bitmaps I needed for my demo into one file and not use the 'cell' method. Since the demo uses only 3 ship bitmaps, 1 laser bitmap and 6 rotating meteor bitmaps I can put all the bitmaps into one file using the gd3asset program and not run out of numbers.

    I had thought that I might be able to use the python method suggested in another post ( see gameduino2.proboards.com/thread/127/bitmap-cells-frustration) to convert a block of same size bitmaps into cells and then combine them into a file with the other bitmaps that I needed. But I could not find a way to do this. SO I quit trying. ( I also will have to learn yet another programming language, Python ). 

    I also noticed that in the frogger demo game that some of the bitmaps contained several cells and others had only one cell. But I concluded that the cells were all the same bitmap. I might be wrong about this. If some one has a definitive answer and is willing to share it I would like to know.

    Anyway I have had fun looking at the python, c++ code and the data sheets. If you are interested I have attached the main code and the converted bitmaps.

pls

The assets rotation can be reached through this function:


static void rotate_Center(float a, int CXY)
{
 GD.cmd_translate(F16(CXY),F16(CXY));
 GD.cmd_rotate(a);
 GD.cmd_translate(F16(-CXY), F16(-CXY));
}

tftlcdcyg,

    Thanks for the information.
