Graphics / [Solved] Sprite Fade Out?

« on: September 28, 2011, 09:42:00 pm »

Hey, i'm kinda new to these forums, although i have been reading up a few threads here and there. But i couldn't quite find a thread to my problem that fixes it. So im sorry if you have read topics like this before.

Now, i have the Fade in working alright as it is, but i cant figure out how to get it to fade out. I am currently using SFML 1.6

heres my code from the splash scene's update method.

Code: [Select]

void SplashScene::Update(void)
{
// Check our App pointer
assert(NULL != engine && "SplashScene::Update() bad app pointer, init must be called first");

bool fadeComplete = false;

for(int a = 250; a > 0; a -= 5)
{
         mSplashSprite->SetColor(sf::Color(255,255,255, a));
if( a == 250)
{
fadeComplete = true;
}
}  

// Drop our state after 10 seconds have elapsed
if(fadeComplete == true && false == IsPaused() && GetElapsedTime() > 4.0f){

engine->mSceneManager.RemoveActiveState();
}
}

and my main loop looks like this.

Code: [Select]

// Loop while IsRunning returns true
while(IsRunning() && mWindow.IsOpened() && !mSceneManager.IsEmpty())
{
// Get the currently active state
IState* scene = mSceneManager.GetActiveState();

// Check for corrupt state returned by our StateManager
assert(NULL != scene && "App::Loop() received a bad pointer");

// Create a fixed rate Update loop
while(anUpdateClock.GetElapsedTime() > anUpdateNext)
{
// Handle some events and let the current active state handle the rest
sf::Event anEvent;
while(mWindow.GetEvent(anEvent))
{
// Switch on Event Type
switch(anEvent.Type)
{
case sf::Event::Closed:       // Window closed
Quit(StatusAppOK);
break;
case sf::Event::GainedFocus:  // Window gained focus
scene->Resume();
break;
case sf::Event::LostFocus:    // Window lost focus
scene->Pause();
break;
case sf::Event::Resized:      // Window resized
break;
default:                      // Current active state will handle
scene->HandleEvents(anEvent);
} // switch(anEvent.Type)
} // while(mWindow.GetEvent(anEvent))

// Let the current active state perform updates next
scene->Update();


// Update our update next time
anUpdateNext += mUpdateRate;
} // while(anUpdateClock.GetElapsedTime() > anUpdateNext)

// Let the current active state draw stuff
scene->Draw();

// Display Render window to the screen
mWindow.Display();

// Handle Cleanup of any recently removed states at this point as needed
mSceneManager.HandleCleanup();
}

I appreciate any support/help that i can get, and im sorry if its just me being stupid.
