Mute Entire App

Solar2D General Questions/Discussion
#21

Back to what you replied before in reply #7, how would I use ICE to make the app store/save the data? I’ve been looking at ICE stuff for a bit, so you can probably answer like I know what I’m doing. :wink: [import]uid: 39302 topic_id: 24043 reply_id: 98576[/import]

Okay, so I’ve got something set up. It’s not working, but I’m not getting an error. What am I missing or doing wrong?

local scores = ice:loadBox( "scores" )  
local player1 = 0  
  
--In the mute button function I have...  
scores:increment( "player1", 1 )  
scores:save()  
  
--In the unmute button I have...  
scores:increment( "player1", -1 )  
scores:save()  
  
--Under all the other stuff I have...  
if player1 == 1 then  
 mutebutton.isVisible = false  
 unmutebutton.isVisible = true  
else  
 mutebutton.isVisible = true  
 unmutebutton.isVisible = false  
end

The app still mutes when I press the button, but like I explained earlier, it doesn’t keep its current state after I switch to another screen and back. [import]uid: 39302 topic_id: 24043 reply_id: 99001[/import]

Instead of incrementing “player1” you might want to set (store) the value 1 for true and 0 for false.

for true
[lua]scores:store(“player1”, 1)[/lua]
for false
[lua]scores:store(“player1”, 0)[/lua]

also, make sure you’re retrieving the stored value from ICE using retrieve so your code would look something l like this:
[lua]if scores:retrieve(“player1”) == 1 then
mutebutton.isVisible = false
unmutebutton.isVisible = true[/lua] [import]uid: 34029 topic_id: 24043 reply_id: 99019[/import]

YEAH MAN! Finally! thanks a ton!!!
I’m new, and this was a challenge. :wink: [import]uid: 39302 topic_id: 24043 reply_id: 99260[/import]

Hi
How can this be done, if I am using globals ? So, when I switch scenes, the pictures will remember if the sound is on or off?

Thank you in advance :slight_smile: [import]uid: 122802 topic_id: 24043 reply_id: 106101[/import]

Have you ever used Ice before? I would recommend checking it out if your haven’t… http://developer.anscamobile.com/code/ice
I use it for my mute buttons, and it works great. [import]uid: 39302 topic_id: 24043 reply_id: 106130[/import]

Hi Nathan

Thank you for your response. I have tried using ICE, but I think it is a little confusing. :frowning: How have you made your mute button with ICE?

Thank you in advance

I haven’t been doing this that long so this isn’t professional advice, but it works for me. :slight_smile: The stuff below is the setup I have in my app.

In your main.lua file add…

[lua]local ice = require(“ice”)[/lua]

In the file that your mute button is in add…
[lua]local scores = ice:loadBox( “scores” )
scores:save()
local muteValue = 0
–If everything is in your main.lua file, put this under the first thing I said to do.[/lua]

Then create the button functions…
[lua]local mutebuttonfunction = function (event )
if event.phase == “release” then
audio.setVolume( 0.0 ) --this mutes the sound
scores:store(“muteValue”, 1)
scores:save()
end
end

local unmutebuttonfunction = function (event )
if event.phase == “release” then
audio.setVolume( 0.3 ) --this unmutes the sound to the volume I want it
scores:store(“muteValue”, 0)
scores:save()
end
end[/lua]

Create the buttons… I use widget.newButton
[lua]local mutebutton = widget.newButton{
default = “soundon.png”,
width = 50, --I recommend making both buttons the same size
height = 66, –
onRelease = mutebuttonfunction,
}
mutebutton.isVisible = true

mutebutton.x = 25
mutebutton.y = 25

local unmutebutton = widget.newButton{
default = “soundoff.png”,
width = 50,
height = 66,
onRelease = unmutebuttonfunction,
}

unmutebutton.isVisible = false --you don’t want this visible yet

unmutebutton.x = 25 --Make sure its in the same spot as the mutebutton
unmutebutton.y = 25 --[/lua]

Here’s what I do to make them switch when they’re pressed…
[lua]local unmutebuttonappear = function(event)
if event.phase == “ended” then
mutebutton.isVisible = false
unmutebutton.isVisible = true
end
end

mutebutton:addEventListener(“touch”, unmutebuttonappear) --tells the mutebutton to “listen” for a touch, then do the unmutebuttonappear function

local mutebuttonappear = function(event)
if event.phase == “ended” then
mutebutton.isVisible = true
unmutebutton.isVisible = false
end
end

unmutebutton:addEventListener(“touch”, mutebuttonappear) --same thing…[/lua]

Finally, here’s the important step to make the app remember if it was muted or unmuted…
[lua]if scores:retrieve(“mutevalue”) == 1 then
mutebutton.isVisible = false
unmutebutton.isVisible = true
else
unmutebutton.isVisible = true
unmutebutton.isVisible = false
end[/lua]
phew… so thats what I do for a stinkin’ mute button. :slight_smile: Feel free to ask more questions!

If anyone else has anything to help me, please let me know. Thanks!

Hi Nathan

Thank you for the help and the code, much appreciated. I have almost got it to work, I just don’t know if I need to place the last code in a function or not? - In general, where have you placed the code?

This code:

[lua]if scores:retrieve(“mutevalue”) == 1 then
mutebutton.isVisible = false
unmutebutton.isVisible = true
else
unmutebutton.isVisible = true
unmutebutton.isVisible = false
end[/lua]

Thank you in advance :slight_smile:

EDIT: Nevermind, I got it to work - With globals and with ICE :slight_smile: Thank you [import]uid: 122802 topic_id: 24043 reply_id: 106284[/import]

Great! [import]uid: 39302 topic_id: 24043 reply_id: 106291[/import]

Hi Nathan

To minimize the number of functions, you can move the content of the “button appear functions”, into your mute and unmute functions. :slight_smile: Just thought that it could be usefull, to optimize your app :slight_smile:

#32

I’ve actually tried that, but I get an error. I believe this happens because in the first function, it doesn’t know what the unmutebutton is yet. It didn’t get that far yet… :slight_smile: [import]uid: 39302 topic_id: 24043 reply_id: 106338[/import]

#33

Hi

Ohh okay, then you need to declare your buttons on the very top of your module :slight_smile: [import]uid: 122802 topic_id: 24043 reply_id: 106376[/import]

#34

hmmm. Won’t that produce an error also because the function that onRelease calls doesn’t exist yet? [import]uid: 39302 topic_id: 24043 reply_id: 106413[/import]

Hi again

No… this is how I have done it :slight_smile: - I am using globals instead of ICE, but the senario is the same :smiley:

[lua]local MusicOff
local MusicOn

local function UnMutePressed ( event )
if event.phase == “release” and MusicOff.isActive then

Mute = true

audio.setVolume( 1, { channel=1 } )

MusicOn.isVisible = true
MusicOff.isVisible = false

end

end

local function MutePressed ( event )
if event.phase == “release” and MusicOn.isActive then

Mute = false

audio.setVolume( 0, { channel=1 } )

MusicOn.isVisible = false
MusicOff.isVisible = true
end

end

MusicOn = ui.newButton{
defaultSrc = IMAGE_DIR…“SM2.png”,
defaultX = 30,
defaultY = 30,
onEvent = MutePressed

}

MusicOn.x = 20; MusicOn.y = 20
MusicOn.isVisible = true

MusicOff = ui.newButton{
defaultSrc = IMAGE_DIR…“SM1.png”,
defaultX = 30,
defaultY = 30,
onEvent = UnMutePressed
}
MusicOff.x = 20; MusicOff.y = 20
MusicOff.isVisible = false

if not Mute then
MusicOn.isVisible = false
MusicOff.isVisible = true

else
MusicOn.isVisible = true
MusicOff.isVisible = false
end [/lua]

I hope that helps :smiley: [import]uid: 122802 topic_id: 24043 reply_id: 106428[/import]

Sweet! Thanks! -15 lines of code for that button plus whatever I get rid of in other buttons… :slight_smile: [import]uid: 39302 topic_id: 24043 reply_id: 106434[/import]
