Planet-Like gravity

So , i wanna remake a game that no one knows , soosiz . It was my childhood game and imo its the best platformer for its unique gameplay back in its time . I basically want to make that the player will snap to the platforms surface , making a planet-like gravity . I would appreciate it if you helped me how i could snap an objects bottom surface to a platforms surface by maybe a youtube tutorial , some code samples or sth

 

You first need to find what object is effecting you (basically by shortest distance, but you can make it so bigger object have more influence)

To apply gravity you just find the direction to it from and and apply a force based on the distance (you can use newton's famous equations for this)

To snap to the surface:
1) cast a ray to said object
2) set player position to the raycast hit position (assuming the player's pivot is at the feet)
3) set player.transform.up to the raycast surface normal


I'm not sure how that translates to 2D (i'm a 3D guy), but it should be pretty samey

 

3) set player.transform.up to the raycast surface normal

Thats probably what im looking for . Thanks for the quick reply!
