how to pan camera over background image up and down

[dreamchaser]

Hello,I am very new here. I used to work with novelty but after finding that it has too many limitations, i decided to work with ren'py. i have an introduction screen were i have a vertical background image named "gate.jpg" and i want the camera to pan over it from up to down and then stay there at the lower part of the image as the game continues.

I looked around at the ren'py wiki and here at the forums and i tried out some codes but most of them are about panning from side to side and never ever about vertical panning. also i just can't get any code for panning to work on my project. can anybody help me ?

With ATL (http://www.renpy.org/doc/html/atl.html# ... n-language) you can do it using different methods. Perhaps the simpler way is by using image align. If your image is taller then your screen and you want to show its top part, you can simply do:

Code: Select all

show your_image_name_here:
    yalign 0.0

To show the bottom part:

Code: Select all

show your_image_name_here:
    yalign 1.0

So, to pan from top to bottom during, say, 3 seconds, you can do:

Code: Select all

show your_image_name_here:
    subpixel True
    yalign 0.0
    linear 3.0 yalign 1.0

Instead of 'linear' you can try 'ease', 'easein' or 'easeout' to your taste.
Yes, to do a horizontal pan you simply use xalign.

There is also examples of panning in the Tutorial game. I recommend playing through it and checking out its code.
