How do I change the tiles of a tilemap in the editor?

I was wondering if there was anyway to change the tiles on a tilemap before runtime. For instance, if I wanted to have a premade structure that would already be there when I previewed the game. So, in other words, is there anyway to change the tiles in a tilemap without using any code during runtime?

With no code, during runtime? Uhm... no?

What are you trying to achieve? Perhaps there is another way to get there.

Sorry if I didn't word myself well, I meant if there was anyway to change it before runtime. I want the tiles to already be changed, before runtime, using the editor.

This should have been the second tutorial you worked though, before starting.

I'm well aware of how to make a platform-game, all I am wondering is if there is any way to change the tiles before runtime, with the editor.

It's described in there.

Thank you, I'm sorry for being rude, and also jumping to conclusions. I really Appreciate it.
