Ren'Py Changing the same image button in multiple ways

[Alfius]

Renpy Noob again,

So I want to do two action on the same image for an image button.

This is the current code

    if imgname != "":
        imagebutton idle im.FactorScale(imgname, 0.15):

This is what I want to do to the image.

        im.FactorScale(imgname, 0.15)
        im.GrayScale(imgname)

While we are here. Can one do something like this?

                                if imgname != "":
                                    image smallimage = im.FactorScale(imgname, 0.15)
                                    imagebutton idle smallimage:

probably a stupid mistake, but I get an error

Can't you just nest the functions within each other?

imagebutton idle im.GrayScale( im.FactorScale( imgname, 0.15) ):

This is the current code

    if imgname != "":
        imagebutton idle im.FactorScale(imgname, 0.15):

Unless your images don't all have the same size, you don't need to do this. Giving a size to the image button should force Ren'py to resize the image.

So you should be able to achieve what you want with just :

    if imgname != "":
        imagebutton:
            idle im.GrayScale(imgname)
            xsize 100 ysize 100

While we are here. Can one do something like this?

                                if imgname != "":
                                    image smallimage = im.FactorScale(imgname, 0.15)
                                    imagebutton idle smallimage:

No, doing this is not possible. The image statement is proceeded at init level. So, "smallimage" will be defined, and defined once for all, before the game effectively start.

Can't you just nest the functions within each other?

It depend of what you do with the image, but normally it should works.
