How to scroll with arbitrary speed any background and still make it seamless? Very simple:
mirror and dock the same sides
example for moving left
Code: Select all
init:
image sky = "images / sky.jpg"
#transformations for moving and mirroring
transform scroll_in (delay = 10.0):
xpos config.screen_width xzoom -1.0
linear delay xpos 0
pause delay
repeat
transform scroll_in2 (delay = 10.0):
xpos config.screen_width
pause delay
linear delay xpos 0
repeat
transform scroll_out (delay = 10.0):
xpos 0
linear delay xpos -config.screen_width
pause delay
repeat
transform scroll_out2 (delay = 10.0):
xpos config.screen_width
pause delay
xpos 0 xzoom -1.0
linear delay xpos -config.screen_width
repeat
init python:
# function combines transformations
# displays
def _scroll (img, effect = None, delay = 10.0):
renpy.show (img + "1", what = ImageReference (img), at_list = [scroll_in (delay)])
renpy.show (img + "2", what = ImageReference (img), at_list = [scroll_out (delay)])
renpy.show (img + "3", what = ImageReference (img), at_list = [scroll_in2 (delay)])
renpy.show (img + "4", what = ImageReference (img), at_list = [scroll_out2 (delay)])
renpy.with_statement (effect)
def _hide (img, effect = None):
renpy.hide (img + "1")
renpy.hide (img + "2")
renpy.hide (img + "3")
renpy.hide (img + "4")
renpy.with_statement (effect)
# all, now you can anywhere in the script
# one line display moving seamless pattern
label start:
scene black
# display (parameters can be omitted)
$ _scroll ("sky", Dissolve (2.0), 15)
pause # enjoy the clouds
# now hide our running pictures
$ _hide ("sky", Dissolve (2.0))
pause .5
