I have the following problem:
- I want a firework (sprite-based object) to pop after the edge of the screen, in the same height than the character.
- before the appearance of the firework, a warning (also sprite-based) must blink for the firework, and stay on the edge of the screen even if the character changes position.
- after the disappearing of the warning, the firework must go through the screen.
Do anyone know how I can get the screen size in order to do this?
