How To Get Player To Stay On Moving Platform? [2D]

The video you linked only went into the creation of moving platforms (which I already have).  I went further into the 3DBuzz playlist and found a fix for the anchor issue, but it was specific to the movement controller created in the past few videos.  Thanks for pointing those out though, I’ll watch them later for information!

I think the best way is to simply add a collider to the player that detects when you collide with a platform that has a tag on it and would make the player be a child of the platform. Then if the collider detects that you exit the collision remove the player as a child. 🙂

Already mentioned that in my OP;

“One solution that “sortof” worked was making the player a child of the platform object on TriggerEnter2D.  Although, this felt sluggish performance-wise and wasn’t as “smooth” as I’d hoped.”

I tried that…but it wasn’t optimal, an example being that the player would be all jittery when at the edge of said platform.  Thanks for the suggestion though. 😛

I’ve never experienced any jittery when I this method in a platform on my game to be honest, there has to be something wrong with your collider or the platform. First of all is not OnTriggerEnter2D is a OnCollisionEnter2D, second is not bad for performance at all. Try removing the friction of your platform to see if the jittery stops.

I’ll give OnCollisionEnter2D a shot!

EDIT: Using OnCollisionEnter2D is working A LOT better than OnTriggerEnter2D, but I ran into a small issue.  Since the platform uses a box collider that covers the entire sprite, a player is dragged with the platform if they touch the sides or bottom of the platform.  Would it be alright to use 2 colliders on the platform game object, one that covers the enter sprite and one that could be an edge collider on the top of the game object to cover the OnCollisionEnter2D script?  I’m just wondering if having 2 colliders overlapping would cause any issues.

Wouldn’t this cause the player to move/bounce up?  Unless you mean applying a downward force onto the player.  I’ll give this a shot as well.

If the platform is moving up, then sure, it would cause the player to move up, but hopefully not bounce.

Tried adding the physics material to the Collider on the platform, didn’t work. :/  Thanks for the suggestion though!

I haven’t seen Brackeys platformer series, so forgive me for my ignorance, but does the character use a rigidbody?

Yeah, the character uses a rigidbody.

Better idea: 
when the platform moves, add its velocity to the player’s as long as they are standing on it.

the platform will use OnCollisionEnter to detect and add things to a GameObject array (this way if other things, such as crates or whatever, land on the platform, they get affected too). Then OnCollisionExit to detect when something leaves so it can remove them from the array.
(if the only moveable object is the player, you can disregard everything about arrays and just have a standard GameObject variable).
Anything in the array get the platform’s velocity added to it
or, if you’re doing it without arrays, just the variable gets it.

thePlayer.rigidbody,velocity += rigidbody.velocity
