Screens and variable trouble (SOLVED)

[blueberryblanket]

I'm having trouble programming screens. I just can never seem to get the hang of them, for some reason.

I have a clock as part of the GUI, that appears like so:



The clock is made of two seperate images, the face and the frame. Right now I have it as a screen, like so:

Code: Select all

screen clock:
        add "ClockFace.png" xanchor 0.5 yanchor 0.5 xpos 1 ypos .1
        add "ClockFrame.png" xanchor 0.5 yanchor 0.5 xpos 1 ypos .1

I also have two variables, $hour and $currenthour. They interact like so:

Code: Select all

if hour == currenthour +1:
            show clockface:
                xanchor 0.5 yanchor 0.5
                xpos 1 ypos .1
                linear 0.5 rotate -72
    if hour == currenthour +2:
            show clockface:
                xanchor 0.5 yanchor 0.5
                xpos 1 ypos .1
                linear 0.5 rotate -144
    if hour == currenthour +3:
            show clockface:
                xanchor 0.5 yanchor 0.5
                xpos 1 ypos .1
                linear 0.5 rotate -216
    if hour == currenthour +4:
            show clockface:
                xanchor 0.5 yanchor 0.5
                xpos 1 ypos .1
                linear 0.5 rotate -288

Now, this code isn't part of my clock screen, since A. linear isn't defined and B. the variables hour and currenthour aren't yet defined. Instead, it's floating about the rest of the code between scenes and is just mucking it up.

My question is, is there a way to include the latter code into a screen? If so, how would one write it? Thanks in advance.

Replying with my new account because I don't watch my old one.

Code: Select all

add "ClockFace.png" xanchor 0.5 yanchor 0.5 xpos 1 ypos .1

You've placed the center (xanchor 0.5) of your clock at position 1 pixel from the left side of screen (xpos 1). Try to change the xpos value.

I don't think that solves my problem; I changed the position of the clock to xpos 2, but that just changed the location of the screen. I want the clock face to rotate, but for the life of me, can't get it to do so without making it an image rather than an omnipresent screen.

you can use at to apply a transform, or you could add a Transform to the screen, something like this:
add Transform("ClockFace.png", rotate=(hour-currenthour)*72) xanchor 0.5 yanchor 0.5 xpos 1 ypos .1
you may need to add some other stuff to do that and you can't put transform_anchor in a Transform yet so if you need that you'll have to take the at approach but that's a possible starting place.

Thanks a lot! It seems to be working just fine. I'll have to test some possible crash-worthy scenarios, but I think this is a step in the right direction.
