(SOLVED) Setting sprite offset and playback rate has no effect. Is this intentional?

Questions
#1

Hello, does anyone has explanation of this?

It seems, these optional properties are useless if you can set them but not use… Forces me to create side-offs when I need to just set animation (to show its 1st frame) but not play it

"playback_rate" for sprites doesn't work

I recommend creating a new post instead of necromancing old threads. (Is there a way to lock old threads? :thinking:)

As for the statement that the properties are useless, I’m not sure I understand?

Well, they work fine if they were set before build process, but if you set them at runtime while you trying to set a new animation, they just don’t do anything, like was described in above posts

Could you please share the code you are using?

Yeah, sure.

function init(self)
    -- if side door then change sprite (isSide is go.property)
    if self.isSide then
       -- DOOR_VIEW only used to add "Front" of "Side" strings later
        view = DOOR_VIEW.SIDE 
    end
    -- set sprite by view
    -- I want to set an animation here, but not play it at the moment it is set
    sprite.play_flipbook("#sprite", "DoorClose"..view, {playback_rate = 0}) 
end

If I print playback_rate, the value is the one I set with sprite.play_flipbook, but the animation still plays from the start.
I tried, also, to set playback_rate with go.set before or after play_flipbook, but the result is the same.

I use Defold 1.9.0

The function signature for sprite.play_flipbook() is:

sprite.play_flipbook(url,id,[complete_function],[play_properties])

The complete_function is optional, but you still need to pass nil if you don’t want to use a complete_function. You can’t omit it and pass the play_properties as the third argument. Try:

sprite.play_flipbook("#sprite", "DoorClose"..view, nil, {playback_rate = 0})

Works perfectly, thank you very much! :orange_heart: :blue_heart:

We should do a better check of the callback argument :thinking:
