How should I lock/unlock images in this case (gallery)?

[Nanahs]

I created a label that is a gallery.

I'm using this:

Code: Select all

label gallery1:       
        
    scene bluescenary
    
screen images1:
    vbox:
        pos (100, 300)
        spacing 15
        imagebutton idle im.FactorScale('image1.png', 1.0) action Jump("image1")
        imagebutton idle im.FactorScale('image2.png', 1.0) action Jump("image2")
        imagebutton idle im.FactorScale('image3.png', 1.0) action Jump("image3")
        imagebutton idle im.FactorScale('image4.png', 1.0) action Jump("image4")


label image1:
    scene image1
    $ renpy.pause()
    jump label gallery1

The images are displayed like this:



It's all ok. But I'm using a Messenger system (viewtopic.php?f=51&t=50153).
And in the chat you can "receive" images.

I wanted the images you receive in the Messenger to only be available in the gallery after you play the label you will receive them.

They would appear "black" in the gallery. Like this:



I was thinking that in the label I use the messenger, after you "receive" the messege, I should use something like:

Code: Select all

$ unlock_image("image4")

But I'm not sure it this code exists, or if it's done this way

Not all images will be locked. Some will start the game available already.

Also, how do I "tell" the game that this image:

Code: Select all

        imagebutton idle im.FactorScale('image4.png', 1.0) action Jump("image4")

Should only be available to open as the others:

Code: Select all

label image4:
    scene image4
    $ renpy.pause()
    jump label gallery1

After I use something like:

Code: Select all

$ unlock_image("image4")

Sorry if it's confusing

Thanks

You can do this in this way.

You have a variable for each image that starts out as locked and set those variables to False as default.

default img4unlocked= False

In the screen you have if-statements for showing the button for the image (if unlocked) or an image showing that this image is locked

Code: Select all

if img4unlocked== True:
    imagebutton idle im.FactorScale('image4.png', 1.0) action Jump("image4")
else:
    add 'lockedImage'

At the event that unlocks the image you do
$ img4unlocked= True

Thank you so much! I'll try doing it
