Transitions

#1 You can either save them in separate level files and just load the next level, or show them as a full-screen image at the start of the level and fade them out using setblendalpha().

#2 Use this :

startGame(expandFilename($Game::DefaultScene));
 function StartSplashScreen1()
{
	//Hide the cursor.
	Canvas.hideCursor();
	//Set the game's content to the MySplashScreen.
	Canvas.setContent(MySplashScreen);
	//Call the EndSplashScreen1 function.
	EndSplashScreen1();
}

 function EndSplashScreen1()
{
	//Check if the MySplashScreen is done.
	if(MySplashScreen.done)
	{
		//If it is done call the StartSplashScreen2.
		StartSplashScreen2();
		//And exit out of this function.
		return;
	}
	//If it is not done, after 100 milliseconds call the EndSplashScreen1 function again.
	schedule(100, 0, "EndSplashScreen1");
}

 function StartSplashScreen2()
{
	//Set the game's content to the TorqueSplashScreen.
	Canvas.setContent(TorqueSplashScreen);
	//Call the EndSplashScreen2 function.
	EndSplashScreen2();
}

 function EndSplashScreen2()
{
	//Check if the TorqueSplashScreen is done.
	if(TorqueSplashScreen.done)
	{
		//If it is done, start the game with the default scene 
		startGame(expandFilename($Game::DefaultScene));
		//And exit out of this function.
		return;
	}
	//If it is not done, after 100 milliseconds call the EndSplashScreen2 function again.
	schedule(100, 0, "EndSplashScreen2");
}
