Simple jump + directionnal pad

Hi,

I'm doing a scrolling platformer..a Castlevania style. I'm using the a_simple_jump.asm in modulescripts\Simpleplatformer
I've set "A" button to jump.

Working : Jump by holding a direction, jump in that direction too.

Problem : If I click only on "A", it doesn't jump at all.

Here's the original code :

; a jumps

LDX player1_object
;;; let's check for if we are standing on a jumpthrough platform,
;;; for which "down and jump" will jump downwards through
;;; comment this out if you do not want that functionality
LDA screenFlags
AND #%00100000 ;; does it use gravity?
BEQ dontJump

LDA Object_physics_byte,x
AND #%00001000
BEQ notStandingOnJumpThroughPlatform
LDA gamepad

Thanks for your help !

Are you sure you correctly assign your script to your buttons in the Input Editor?
Maybe you assign it on "Press" Left + A ?

You're the first person I heard having this issue.

Yes.

You should remove the ladder script. It’s nlt a input script, it’s a tile script.
All the ladder tiles used this script. It’s automatic when you will be on a ladder tile and press up, you will go up.
No need to assign this script here (and it might cause issues, here).
Try again your jumps, after removing it.

it's done, I've remove "Ladder script"... no it's not better for the jumping.

Weird, I have no idea what’s going on...
If your’re ok, could you send me your NESMaker folder zipped, I could check and tell you what is the cause of the problem with your project and give you a fix?

No problem. I will send you the information in private.

Check your Player's action step, and unset the "ignore gravity". This flag stops objects from moving vertically... (and horizontally too, originally, but I fixed that in my projectiles tutorial)
