Splash Screen

[eliotttesnier]

This pull request introduces a splash screen as the initial scene when the client application starts. The splash screen displays animated title and subtitle text with configurable styling and transitions, and plays dedicated splash music. After the animation completes, the application transitions to the connection state. Several constants and resources are added to support this feature.

Splash Screen Feature Implementation:

• Added a new SplashScreenState class, including its implementation and header files, which displays animated title and subtitle text, handles music playback, and transitions to the connection state after a set duration. (client/gsm/states/scenes/SplashScreen/SplashScreenState.cpp, client/gsm/states/scenes/SplashScreen/SplashScreenState.hpp) [1] [2]
• Registered the SplashScreen subdirectory in the build system and included the new state in the project. (client/gsm/states/scenes/CMakeLists.txt, client/gsm/states/scenes/SplashScreen/CMakeLists.txt) [1] [2]
• Updated the application to start with the splash screen instead of the connection state. (client/Core.cpp) [1] [2]

Constants and Resource Management:

• Added new constants for splash screen animation timings, font sizes, text content, and music path. (client/constants.hpp) [1] [2]

These changes collectively provide a polished introduction to the application, improving the user experience with a branded splash screen and smooth transition into the main connection flow.
