Okay, so, I made a levelASM code, I tried to create my own double jump, and it works! But I noticed that instead of double jumping, I can jump as many times as I want by pressing the jump button. That's not what I'm trying to do.
So, my question is:
How would I make a code only execute once? Ot at least, make the code execute again until I touch the ground?

Create a flag it can check, that resets when touching the ground

;This part should be there somewhere at the top of your levelasm
LDA $13EF
BEQ asdf ;check if mario is touching ground
STZ !Freeram ;if yes, reset custom counter
asdf: ;otherwise, keep the counter as it is

LDA !Freeram ; check freeram to see if player is allowed to jump
BNE notallowed ; if not, skip the jumping routine
INC !Freeram ;if allowed, increase freeram so player can't jump again
;code for jumping here

Hm, I'll see what I can do with that. If I have a question, I'll edit this post. Thanks!

Edit: Eh, it's still not working, Mario kees jumping the amount of times he wants if I press the jump button (well, the spin jump button actually). It should be double jump, not multiple jump. What's wrong?

Try this code

Code

!FREERAM = $60
!JUMP    = $B0

	LDA $77
	AND #$04
	BNE Reset
	LDA !FREERAM
	BNE +
	LDA $16
	AND #$80
	BEQ +
	LDA #!JUMP
	STA $7D
	INC !FREERAM
+	RTS
Reset:
	STZ !FREERAM
	RTS

I change my layout every 4-5 months
