Change Background Image with animation

creativeapps

I want to change background image night to day with day in fad out effect on basis on score. For example game starting in a day with 0 score, after getting 50 it will afternoon and on 100 score i want to display night.
all this background change will happen with fade in out smooth animation effect.
Its that possible? any sample available? please let me know

i would just have all the images regular like u would during the day, and have a black actor that covers the whole screen and has a alpha of like .7

then just interpolate the alpha to 0 to fade into day

cheers

thanks john but how dp I call that black actor with .7 alpha on score 50? means how to convert day zero score background to night 50 score background

JohnPapiomitis

so you want it to fade to night when the scores fifty?

then have the actor the covers the whole screen and have its alpha set to 0

then have a rule in that actor when attribute score equals or is greater then 50

interpolate alpha to .7
