Problem switching texture on a gui node (SOLVED)

Questions
#1

Hi,

I am having a problem with switching a texture of a sprite.
Google shows that I must use “gui.play_flipbook()” when using atlases.
But I don’t understand what to do…

Thanks!

gui.set_texture() is not what you want in this case most likely if the texture is already set on the node and you only want to change the animation.

gui.play_flipbook() is correct for changing the animation as long as that animation is defined on the atlas texture it should work.

Can you post a code sample of what’s not working for you exactly?

#3 
node = gui.get_node("SpeakerON")
	if (DelayAllUserInput == 0) then
		if gui.pick_node(node, action.x, action.y) then
			if (ScreenFadeStatus == 0) then
				gui.set_scale( node, vmath.vector3(0.85, 0.85, 1) )

				msg.post("level:/Audio#MenuClick", "play_sound", {delay = 0, gain = EffectsVolume})

				if (MusicVolume == 0 and EffectsVolume == 0) then
					MusicVolume = 1
					EffectsVolume = 1
					gui.set_texture(node, "SpeakerON")
				else
					MusicVolume = 0
					EffectsVolume = 0
					gui.set_texture(node, "SpeakerOFF")
				end
						
				sound.set_group_gain("music", MusicVolume)
				sound.set_group_gain("effects", EffectsVolume)

				PM.PlayMusic(CurrentMusicPlaying)
																
				DelayAllUserInput = 20

				NextScreen = 2
				ScreenFadeStatus = 1
						ScreenFadeAlpha = 0					
			end
		end
	end

AS Pkeod said gui.play_flipbook(), I used this for a button pressed effect, when the button is pressed the image changes to give the effect the button has been pressed. In your atlas your button looks like this:

image

Images, no animations. And in the code I change them with:

if gui.pick_node(self.node_btn_play, action.x, action.y) then
    if action_id == input_click then
        if action.pressed then
            gui.play_flipbook(self.node_btn_play, hash("btn_play_down"))
        elseif action.released then
            gui.play_flipbook(self.node_btn_play, hash("btn_play_up"))
        end
    end
end

Hope is what you were looking for.

Hi,

Code posted above.
When user clicks on speaker icon I want the sprite to change.
(SpeakerON when audio is on, and SpeakerOFF when audio is off)

Both sprites above are in “TitleImages.atlas”.
Any ideas?
Thanks!

In your previous post you wrote:

gui.set_texture(node, "SpeakerON")

Where SpeakerON should now actually be the name of your atlas like:

gui.set_texture(node, "TitleImages")

To select the image/animation from that atlas, you’ll need to add gui.play_flipbook() as well. Like so (SpeakerON is the name of the image):

gui.play_flipbook(node, "SpeakerON")

You could try this in your script:

if (MusicVolume == 0 and EffectsVolume == 0) then
	MusicVolume = 1
	EffectsVolume = 1
	gui.set_texture(node, "TitleImages")
	gui.play_flipbook(node, "SpeakerON")
else
	MusicVolume = 0
	EffectsVolume = 0
	gui.set_texture(node, "TitleImages")
	gui.play_flipbook(node, "SpeakerOFF")
end

Hi,

Got it working.
Did not need: “gui.set_texture(node, “TitleImages”)”

Thanks!
