Ok, I believe there are not any attributes that would do that, I think the easiest way to do that would be to make a black and white version of the background, import it into GS, set it as the main im

Thats really strange ;-) Because this is effect I want to gain. And you say, that you are constraining one actor to another with such result? Hmmm...

If game.clk is an attribute with value 3 then Help! will flash up every 3 seconds.

You can't change an attribute that is constrained.

@Ludwig the lights switching on is simply a black solid actor with transparency that interpolates to 0 when an attribute is activated. (If that's what your referring to?)

Well you have to tell the game which attributes you want it to save. And when to save them.

Now I understand why he puts 160 as a value!! But I haven't understood why he uses this attribute with the constrain attribute in the platform and in the slider area?

I have two actors in the scene, one of them is rotatable by player (so player can touch it and rotate). It constrains game attribute to actor's rotation.

Just saw the video on Youtube. I wonder in the end when you push a button on your Dark Asylum app, how do you switch on the lights in your room? Is that GS attribute I don't know of (Image)

First I'm getting rid of any 'change image' behaviors and using change attribute image name instead.

Because my method uses only one attribute it was easier to implement (and I am a bit lazy sometimes) but I see a lot of advantages in yours.

Create a real attribute game.timeStamp

When you would use change to get back to the initial timer value in the "when timer = 1" rule the interpolate value to 1 wasn't finished when it was 1. So the change attribute would

Make a (self) attribute named timer

i make a boolean attribute "animation" . set false as default.

OK, so we know that we're supposed to use "change attribute" instead of "change image" , but I'm not exactly sure I know how to do that. I want to make an actor ch

Can we combine attributes?

No I do not Believe So. The only way would be an expression editor on the font size attribute and there is not one. So no.

Make two attributes. TouchX & TouchY.
