How do I make a 8 direction game with jump?

Hello. I am coding a game like the old zelda and I get stuck on one thing: in the game I would like my character to jump when he is at the top of a cliff for example to land at the bottom of this cliff. the only problem is that I don't know how to do this. can someone help me?

What about:

when pressing jump

disable collision

disable player input

let the player move down on y-axis

enable collision

enable player input

?

that can be an idea but how to make so that the jump does not disable while I am still "in the air" (= on a solid)

Sorry, I think I do not understand the question.

when i jump off a cliff i disable player collisions and make it go down. But when should I reactivate the 8directions behavior?

Maybe it's possible to detect the bottom of the cliff?

If player.y > cliff.bottom: reactivate 8 direction?

this doesn't work with tilemap

Can you see the cliff-side in your tilemap?

You could set your 8dir to inactive when your sprite is over the cliff-side.

Maybe make a tilemap of all cliff-sides.
