Merge in CGD/gather-and-defend from progress_worldmap to main
* commit '25d574714f32e7eec33f90451d2054cb643722ff':
add the save and unlock next level after finishing anyone
problème :
Il y avait plusieurs manières de faire planter le loading screen en appuyant sur des boutons
changements:
- turn off buttons when loading screen is active
- turn on buttons when loading screen is not active
- add event aggregator class to project and migrate every event to it
- fix bugs and regressions
besoin :
- le level était loadé directement au moment de cliquer dans le level selector ce qui n'est pas très fenshui
solution :
- fade out avec nuages
- les tuiles tombent à leur place au lieu d'apparaitre toutes en même temps
Level selector was already working after work by William but some small bugs remained to be fixed + it wasn't possible to return to level selector once we were in the level.
- it's now possible to go back to level selector from Level
- LevelManagerScript is no longer a singleton (this way, it resets with the Game scene unloading)
- Added a property drawer for using scene files in inspectors
