background animation help

arneeezy

Hey peeps i am new to Gamesalad and i really need help with the background of my game. It will take place in a cave what i need done is a button that when pressed will light up the background making every thing visible but every second it gets darker again. I tried adding an animation of my background at 1fps just putting a slightly darker opacity but its not working properly. Any help would be greatly appreciated.

Hey, are you using Mac or Windows? i will create a little Demo for you

well my GS wont work with me right now. But this is what i did:

have 4 differend layers: 1 the cave. 1 for the image to make it darker(just black) 1 for the button and 1 for the outside (explain later) (in this order)

make the image for the flash black and the alpha 200

make a boolean called: flash

make a integer called: flashspam



outside image(not on screen)

drag the image where you want the button go so peeps cant spam the button.

make 2 boolean attributes called: pos.x and pos.y
no rule
consrain attribute: pos.x to self.position.x
consrain attribute: pos.y to self.position.y

Flash button:

Rule: touch is pressed
change attribute: game.flash to true
change attribute: game.flashspam +1

rule:
attribute: game.flash true
consrain attribute: self.position.x to pos.x
consrain attribute: self.position.y to pos.y


Layer to make it darker:
rule: attribute game.flash = true AND attribute game.flashspawn >= 1
interpolate: self.colour.alpha to 0 for 3 seconds in a linair function.


rule: attribute game.flash = false
interpolate: self.colour.alpha to 200 for 3 seconds in a linair function

timer: after [how much seconds do you want to make it dark]
change attribute: game.flash to false
change attribute: game.flashspawn to 0


if this not work i dont know what to do.
maybe i made some mistakes so i hope someone can make them correct
im not enlgish so if it is bad im sorry i did what i could do.

good luck and cheers
