How would I create Rock Climb?

Simply put, how would I create a rock climb effect? Possibly with the rocks tumbling down?

I tried that. Can someone explain in a bit more detail? Be it with where the scripts go and stuff?

BOOMP. Bump. plz 'elp. i really need this system in my game.

please. Can somebody help meh?

Do what the wiki says, either check if a player has a Pokemon with Rock Climb then set a move route when interacting with a rocky surface.

Or copy how Waterfall works outside of battle(right click on a script then search all scripts for WATERFALL till you find the out of battle effect), put it below Waterfall and edit it to fit Rock Climb.

Alright thanks Roaming. And if I copy the Waterfall Script, how do I add the Rock tumble effect when the player is climbing?
