Graphics / Draw Missing!?

i know unicode allows for international characters but does turning it off do anything that would majorly affect my program?

otherwise...i could have fixed this a long time ago

i still cant figure out how to be able to use std::strings in GetModuleFileName() or convert TCHARS to std::strings

also, can someone explain the poor quality of the text in the images of my program (they are really pixelated on my 1024 x 768 screen)

**why does everything on the site seem so much smaller?

thnx man, it fixed the errors!

this is correct

Code: [Select]

for (int i = 0; i < 5; i++)
   {
      Money[i].SetImage(money[i]);
      Money[(i + 5)].SetImage(money[i]);
      Money[(i + 10)].SetImage(money[i]);
      Money[(i + 15)].SetImage(money[i]);
      Money[(i + 20)].SetImage(money[i]);
      Money[(i + 25)].SetImage(money[i]);
   };

making 30 images is too slow and costly, so creating 5 sprites of each money image is more efficient and loads quicker

as my small image in a previous post shows, the text in the images are kind of grainy. im scaling 960 x 720 images into (1024/6) x (768/6) images to fit all 36 images on the screen...why do they look kind of bad?

sorry, i changed the size of Money[] to 30 to hold the needed 30 images unless there is a way to duplicate sprites w/o having to create more sprite variables

im making progress, but a problem has popped up. i was using the debugger and my array for my "money" sprites has all the sprites loaded, their positions set, and the loop has the correct numbers to draw...but only the first row appears? here's my code, i cant seem to find the problem

Code: [Select]

for (int i = 0; i < 5; i++)
{
Money[i].SetImage(money[i]);
Money[(i + 5)].SetImage(money[i]);
Money[(i + 10)].SetImage(money[i]);
Money[(i + 15)].SetImage(money[i]);
Money[(i + 20)].SetImage(money[i]);
Money[(i + 25)].SetImage(money[i]);
};

Code: [Select]

void PositionSprites()
{
float xpos = (ScreenWidth/6);
float ypos = (ScreenHeight/6);
float x = 0;
float y = ypos;

for(int i = 0; i < 6; i++)
{
Categories[i].SetPosition(x, 0.0f);
x = x + xpos;
};

for(int i = 0; i < 5; i++)
{
Money[i].SetPosition(0, y);
Money[(i + 5)].SetPosition(xpos, y);
Money[(i + 10)].SetPosition((xpos * 2), y);
Money[(i + 15)].SetPosition((xpos * 3), y);
Money[(i + 20)].SetPosition((xpos * 4), y);
Money[(i + 25)].SetPosition((xpos * 5), y);
y = y + ypos;
};
}

Code: [Select]

for(int i = 0; i < 30; i++)
{
if(CheckMoney[i] == 1)
App.Draw(Money[i]);
};

i switched to bmps cause the pngs werent working...but now the image sizes are much bigger (the pngs are exported from powerpoint slides --> a problem?)

--is there a way to get rid of sf::clock? i want to implement a timer so that SFML shows a "loading screen" while loading images in the background, but dont want the sf::clock to continually run and waste resources (im targetting older hardware so i need to save as much space as i can)

**still need help with GetModuleFileNameExW

this is strange, the loop goes through 3 times and then on the 4th loop, questions[4] cant seem to load C:/Jeopardy/Questions/Slide5.png (but the image load fine in GIMP and so the loop breaks (does lack of memory also cause images to not load?)

--using GetModuleFileNameExW i get an identifier not found?

very odd, this for loop breaks out after 5 iterations...even though it should run 30 times right?

Code: [Select]


int LoadImages3()

for(int i = 0; i < 30; i++)

middle = Convert((i + 1));
image = base + "Questions/Slide" + middle + end;
if (!questions[i].LoadFromFile(image))
return -1;
image = base + "Answers/Slide" + middle + end;
if (!answers[i].LoadFromFile(image))
return -1;
};

return 1;
}
