Hello,

I would like to make fade in/out effect in my code.

I have sprites on the screen, I could use the SetSpriteColorAlpha command on each of them, but do you know another (and easier) method to do this kind of effect ?

By the way is there a kind of "image collections" or "sprite collection" variable in agk ?

Thanks a lot,
alain

I often use a single sprite with no image that covers the whole screen and colour it black. Then just adjust the alpha component of the sprite to fade it in, make sure you have it set to a lower depth than all the sprites you want to hide though...

What Baxslash says You can use different colours too, and things like mottled effects. I know it sounds obvious, but it can dramatically change the mood of your game.

There are no object collection commands, unless your objects are physics objects. Then, you can add them to groups and set how they interact with one another.

It's possible to assign you sprites to a group, and then loop through all the sprites, check to see if they are in the group, and fade them if they are.

But I do the same as baxslash, one full-screen black sprite that covers everything and can be alpha-faded to reveal or conceal.

But it can be more creative than that! Consider a sprite that is twice as tall as the screen, with an image that fades from full transparent to opaque halfway down it's height, then is full opaque for the bottom half. Slide that up over the screen and you have a soft-edged wipe-to-black.

Lots of options...

EDIT: oops, didn't see Bat's post until I'd posted.
