[possible BUG] Animation Sprite, backwards play

sektor-13

Hello,

Not sure if this is bug or the way PLAY BACKWARD is implemented, so: (sorry i don't know how to set this to show code in window )

Example: Using Animation Sprite node.

this works OK

if Input.is_action_pressed("ui_down")
	Sprite.play("Crouch")
if Input.is_action_pressed("ui_up")
	Sprite.play("Crouch",  true)  #plays in reverse

this doesn't work, it just skips animation - no backward play

if Input.is_action_pressed("ui_down")
	Sprite.play("Crouch")
	# ...some code..
	Sprite.play("Something_else") #change to some other animation
if Input.is_action_pressed("ui_up")
	Sprite.play("Crouch",  true)  #plays in reverse

There is workaround if you set animation and frame of the animation before calling BACKWARD play like this:

if Input.is_action_pressed("ui_up")
	Sprite.animation = "Crouch"
	Sprite.frame = Sprite.frames.get_frame_count("Crouch")
	Sprite.play("Crouch",  true)  #plays in reverse

To sum it all up, if you change animation to something else, GoDot doesn't know how to play backwards previous animation.

thanx

Looking at the code, the problem could be how you are calling the play function. I think it needs to be Sprite.play("Crouch", false) to play backwards.

That said, I think the Godot editor would complain, so this likely isn't the issue. This sounds like a bug, so I would report it to the Godot GitHub repository, after searching to make sure no other issues on this bug have already been opened.

Out of curiosity, does the following work:

if Input.is_action_pressed("ui_up"):
	Sprite.play("Crouch")
	Sprite.play("Crouch", false)

If this works, then it might be something is not being properly set when the reverse flag/boolean is true and the animation is different then what is already playing, which would defiantly be a bug.

(Side note: welcome to the forums!)

I reformatted your post :smile:

You can edit your post to see the changes I made. The changes were primarily replacing dashes (-) with underscores (_) to tell Markdown to make a horizontal line, removing the #, indenting all of the code blocks with a single tab so it is formatted as code, and removed all of the > characters.

Hi,

Thank you for reformating. Firstly i just used standard text with symbols and all went to hell, so i tried to quickly fix it to be at least readable. :)

Regarding my code, it is not directly copy/paste, i wrote it here directly made a few mistakes with quotes and also a mistake writing FALSE as it should be TRUE (for BACKWARDS). Didn't make this mistake in my real code.

i will fix my first post

Looking at everything again, with the corrected code, I don't really see what would be causing the animated sprite not to play backwards. If I had to guess, it is likely something isn't being set correctly in the Godot code when the animation is supposed to play backwards.

I would suggest opening a bug on the Godot GitHub repository, since this is almost certainly a bug.
