Right now, i’m with Introduction to C++ with Game Development: Part 9,
and i understand it. The problem is in the assignment:
“Load an image, display it, and fade it (slowly) to black.”
I don’t know if says that the image fade it slowly into black, or the
display around the image fade it slowly into black. If is the first
option, i need help. With the second option i already made it. The
examples in this part use “m_Screen->Clear(x);”, but doesn’t have
relationship with an image, only with the screen.
So, is there a way to modify the colors in a image, apart from Photoshop

I believe you are supposed to fade the whole screen, including the
images you load, to black.
When you load an image onto your Surface using DirectX, all that’s doing
is placing each pixel of that image into the large array talked about in
“Pixel* address” points to the start of this array, and in that
particular appliation, the array is ( 640 * 480 ) elements in size, or
So, these images are not their own entity anymore. They’ve been
plastered into this array and now exist just as elements of the array.
You need to use a loop to cycle through each element of the address
array and set the Red, Green and Blue bytes increasingly closer to 0.
Keep in mind that on each frame, the image is redrawn (copied) to the
array with its original colour values.
I hope this helps, without spelling out the solution.
Thanks Lokked, now i remembered to use “address” from the previous
part and used. Taking the value from every dot in the screen was easy,
but to rewrite it take some time to resolve. At last, i made it after
check the code with the debugger and finding the problem.
