Develop 2D game Inside Canvas Scaler

Hi guys,

I'm new to unity and i came from cocos2d-x. I've realized that it's difficult do a multi resolution 2d game on unity without paid 3rd plugins available on Asset Store.

I've made some tests and i'm able to do multi resolution support in this way:

1- Put everything from UI (buttons etc) inside a Canvas object in Render Mode Screen Space - Overlay with 16:9 reference resolution and fixed width.

2- Put the rest of the game objects inside a Game Object called GameManager with the Canvas Scaler component in Render Mode Screen Space - Camera with 16:9 reference resolution, fixed width and the Main Camera attached. After that, all game objects like player, platforms etc inside GameManager need to have a RectTransform component, CanvasRenderer component and Image Component for example.

Can i continue developing the game in that way, or this is a wrong way to do the things?

Regards
