[RESOLVED] Image Corruption During Runtime

Hey again. GRRLIB has been working pretty good until I started using GRRLIB_Printf() to display text on the screen. All it's supposed to do is display settings and game score, but the image corrupts a few seconds after displaying. Like the function displays them right and then after about 3 seconds the text just turns into what looks like sand.  After showing the text it also sometimes messes up the program as well (starting a game won't work).

I'll post pictures if anybody needs them.

Thanks for any help,
~BW

Hi, I think code would be better wink

Re: [RESOLVED] Image Corruption During Runtime

Thanks for your help, but here's a lot of information.

Problem:

Well now the GRRLIB_Printf works fine, but it messes up the options background.  When my program starts it works fine, and then you go to options and it works fine. Then you can display the score, which works fine, and then it goes to the menu. Then you can repeat that one time. But if you displayed the score twice and open up the options you get messed up options background 1. Then if you try to make it display the score it does the delay (but doesn't display) and then it goes to the menu. Then if you open up options you get messed up options background 2. Then if you make it display the score it works fine and goes to menu. So then it stays that way.

Also if you restart the program it does the same thing as describe above.

So here's the pics and code, and if anything needs to be explained more just let me know.

===============================

Score Display Code (GRRLIB_Printf):

I removed some of the comments, but that was it. The complete code has it as is.

Code:

int  game_score = 0;  //Actual game score.
int  game_life  = 5;  //Make lives variable depending on difficulty/options.
bool game;              //This either increases your score or decreases your lives based on game performance.
bool game_easy = true;//The easy/hard difficulty variable.

void score()
{    
    GRRLIB_FillScreen(0x0000000F);
    
    GRRLIB_texImg tex_font = GRRLIB_LoadTexture(font);
    GRRLIB_InitTileSet(&tex_font, 16, 16, 32);
    
    GRRLIB_Printf(100, 100, tex_font, 0xFFFFFFFF, 2, "SCORE: %d", game_score );
        
    GRRLIB_Printf(100, 175, tex_font, 0xFFFFFFFF, 2, "LIVES: %d", game_life);
    
    if (game_easy == true)
    {GRRLIB_Printf(100, 250, tex_font, 0xFFFFFFFF, 2, "DIFFICULTY: EASY");}
        
    else if (game_easy == false)
    {GRRLIB_Printf(100, 250, tex_font, 0xFFFFFFFF, 2, "DIFFICULTY: HARD");}
    
    GRRLIB_Render();
    
    usleep(3*1000*1000);
        
    GRRLIB_FillScreen(0xFFFFFFFF);
}

Options Display Code:

Code:

void OPTIONS()
{
/* Locations

Re: [RESOLVED] Image Corruption During Runtime

I had this same problem with Mahjongg and ended up only creating textures for the scenes / menus as i needed them and freeing them up when moving between menus or scenes

I've not looked at your code, but if I were you I would check for any other possible memory leaks as this was partially responsible for the problems I was seeing too

Re: [RESOLVED] Image Corruption During Runtime

Hi, in your score() function you keep allocating memory, so each iteration by calling GRRLIB_LoadTexture you do a malloc. tex_font is never freed from memory, so after GRRLIB_Render(); put:

Code:

GRRLIB_FreeTexture(tex_font);

Re: [RESOLVED] Image Corruption During Runtime

I was just looking at the while loop of your main function and there seems to be some pretty crazy things going on in it.

So if you don't mind I thought I could give you some advice to clean it up? The main things that stand out for me are:

Why are there multiple renders and scan pads? The best bet is to do a scan of the pads at the top of your loop and then a render at the end (making sure that you display your cursor last just before the render) - (unless you are trying to get a particular effect that I am not seeing)

You do a rumble(0) in each of the conditional (if) statements, this means that you are always doing this so do this just once outside of the conditional logic

There is also a lot of cases where you do something like this:

Code:

            if (normal_menu == true)
            {GRRLIB_DrawImg(0, 0, tex_button2, 0, 1, 1, 0xFFFFFFFF);}
            
            else if (normal_menu == false)
            {GRRLIB_DrawImg(0, 0, tex_button2_i, 0, 1, 1, 0xFFFFFFFF);}

As normal_menu is a boolean then you can be sure that if its not true it has to be false so don't need to check for this, also you can use the ? : operators so it would look something like this:

Code:

            GRRLIB_DrawImg(0, 0, normal_menu==true ? tex_button2 : tex_button2_i, 0, 1, 1, 0xFFFFFFFF);

I hope this helps + sorry if this comes across as interfering

Re: [RESOLVED] Image Corruption During Runtime

Thanks Crayon and JustWoody, I appreciate any help, and I've been cleaning up the code a little. I know the code is a little less than decent, but I want to get the game demo working and then clean up the code (but thanks for the hint on the ? operator (I forgot about because I never use it)).

The code's rather a mess now, but hopefully someday it be as beautiful as a golden-laced marble statue...

Re: [RESOLVED] Image Corruption During Runtime

Hey, I have a few words to say on the rumble function.

First, this code allocate memory each time is't called for nothing:

Code:

int rumble_on = 1, rumble_off = 0;

Use #define instead:

Code:

#define rumble_on   1
#define rumble_off  0

Secondly, when you know the result of a calculation, don't let the processor do it. When it's in a loop it takes time for nothing.

Code:

        usleep((.5*1000*100));  ///This is in microseconds so 1,000,000 microseconds = 1 second.

Should be:

Code:

        usleep(50000);  ///This is in microseconds so 1,000,000 microseconds = 1 second. Result is (.5*1000*100)

I have done some code for rumbling if you are interested. Check this:

Re: [RESOLVED] Image Corruption During Runtime

Thanks again for the optimization help. I'll take a look at the rumble code as well. My C/C++ isn't the best in the world, but much thanks.

Also, I have a non-related issue between GRRLIB versions. The SVN version (rev101) is giving me errors:

But the GRRLIB 4.0.0 release version isn't giving me these problems. I'm using the release version now, but I just wanted to see if you know anything about the rev101 errors (or if I should even be using rev101...). My code is the about the same as you've seen above.

Re: [RESOLVED] Image Corruption During Runtime

In the svn version GRRLIB is using pointer to texture image.

Ex:
GRRLIB_texImg *tex_Game_Over = GRRLIB_LoadTexture(Game_Over);

Re: [RESOLVED] Image Corruption During Runtime

I have another small hint, when you are checking a boolean you could simply use if/else. There is no need for a else if, the second choice is always the opposite of the first one:

Code:

            if (game_easy == true)
            {
                game_easy = false;
                game_life = 3;
            }
 
            else if (game_easy == false) // Problem is here
            {
                game_easy = true;
                game_life = 5;
            }

By doing so, you will save one call to the CPU wink

Another thing, srand does not need to be in a loop. Call it once: http://msdn.microsoft.com/en-us/library … S.71).aspx

Finally (for now), instead of this:

Code:

    for (int game_count = 1; game_count <= GAME_NUM; game_count++)  //This is to keep track of which games have been played
    {game_played[game_count - 1] = false;}  //in a session.

I would use this (you save one operation by iteration):

Code:

    for (int game_count = 0; game_count < GAME_NUM; game_count++)  //This is to keep track of which games have been played
    {game_played[game_count] = false;}  //in a session.

Even better woulder be to use a memset: http://msdn.microsoft.com/en-us/library … S.60).aspx
