note that shooter does not have a comma after it. This will have the same effect that I think you are tryin.g to achieve but the first offset will be position 0 (zero) and not position 2 (two).

One word of advice: consider using std::string instead of char* you can look it up in the compiler's help des.

string.h would let me use string as a variable.. but do i have to write namespace std?

thanks alot with the heads up.

You can avoid the std:: by adding the line

using namespace std;

Right after all of the #include statements.


Secondly, the exception:

You load the image as Id 2, but stretch sprite calls for image-2. Before that but after loading the image, you increase the id to 3. So, 3-2=1 which by your code above does not exist.... Thus, your exception...

Hope this helps you figure it out...

JTK

Edit: what was I thinking? Isn't the first parameter to dbStretchSprite the id of the sprite to stretch? In any case, you still did not create a sprite with an id of 1. In fact you didn't even create any sprites at all.

my purpose of image-2 is to increase the width of the sprite_id 1 every load completes.


the stretch sprite call id 1 and adjusts its width by (image-2)*100/6.

i dont really get it why theres an exception.

So image id 1 does exist? You don't show its creation anywhere.

Are you sure that you are not calling load_mainmenu() to many times? Once you call it to load the shooter.png file, image will equal 8 which is an invalid array position.

We may need to see more code to help with this...
