I am trying to make my sprite to appear from alpha of 0 to alpha of 255. But when I try my code,program just freezes and loads up after all the time has passed.

Header


CPP


I have also tried using dbWait,dbSleep but it makes no effect..

Any help would be appreciated.

Programming merges these two-Nothing works,and you don't know why.

I think dbSetSpriteAlpha sets the alpha only once and after the sprite had been rendered the next dbSetSpriteAlpha has no effect.
What i think you should is to delete the sprite every time and create it again using the next higher value of alpha.

Or not.

Your application can't guess when you want it to render your scene again; All it's doing is running through your whole loop then rendering it after it when it hits a dbSync() call.

Also, use the Sleep function to pause for a specified amount of time, it's much kinder to the CPU than busy waiting, which is what you are currently doing.

think of dbSync(); as a screen updater, if you do something and you need to see it, use it when ever something is in a loop and will run until the condition is met.

Yeah,now I understand it Some time ago I thought there can be only one copy of this per project.
