heya, I'm working on a program that displays an extensive animation. It might be a sprite or bitmap. However, I want the black (or blue) program-run screen to disappear only showing the animation. How?

not sure if this helps any but it will make image fade away

void fadeimage( void )
{
int count = 0;

for ( int count = 255; count >= 0; count -- )
{
dbSetSpriteAlpha( myimageidnumber, count );
dbSync( );
}
}

yo steve

I have seen your replies all over these boards. I think your doing a great job!

The code is not really fading my background away; as far as the black / blank program screen. I have not loaded an image yet for the imageId variable. Keep up the good work, steve

Say, is the extra dbSync(); really necessary? I notice my program is running smoother though... Thanks lol

umm good question !!!! i guess cos it was in a loop i added that but may not be needed...

Thanks for your nice words my thinking is its cool if you can help out with some code cos we have all been there scratching our heads on how to do stuff so why not share code if its gonna make somones day ??? Lots of people helping on here so really thanks to
everyone.

I was not sure it would help out too much with getting rid of your background but hoped it may be of use to you, maybe give you ideas or something....

By the way Steve why are you initializing int count twice? It already initialises in for() loop

So it may look like:


And for you to know ketchup mustard dbSync(); acts as a screen refresher, something like dbCLS();

Edit: ohh I wrote different thing that you want xD
you may try:


Theory-When you know everything,but nothing works.
Practice-When everything works,but you don't know why.
Programming merges these two-Nothing works,and you don't know why.

Hi there Murloc, many thanks for your comments and your idea to make that function a bit more flexable.
Regarding initializing count twice i will tell you the reason.
A while back i read a book on c++ and it was mentioned in there to
do that. I think it said something like do not make assumptions about local variables in functions. So give them a value !!!
Thats how i ended up doing that well it may be totally wrong so thanks for the comment there.
