There are pros and cons to using only blank text objects.
Pros:
It’s much easier to organize since it is smaller than most other objects
Blank text objects are invisible in play mode, so you won’t see flashing objects when playing the game.
Cons:
It is sometimes difficult to find the object you are looking for. At this point, it is best to name your objects to make them easier to find. Grouping them by type or function is also good practice.
Here’s a tip for making a game with one object (if you ever make one):
If you can’t think of a name for the single object, name it “{game_name}.game_engine” where {game_name} is the name of your game.
Use custom rules to group your functions (i.e., Broadcast Handlers, Animation, GUI, User Interface, Visuals, etc.). This will make it much easier to find the rules you are looking for, especially when coding a large game.
