[Tutorial]Fade in and Fade out (VERY EASY)

[RDilux]

I had alot of problems making fade in and fade out on DSGM 5.
But i got a solution for everyone now!!!

Create 2 objects and name them like fade_in_obj and fade_out_obj.

In fade_in_obj we gonna do it like this

Event Type: Create
Declare i as Type s8 with a value of 0 (i;s8;0)
Loop i from -16 to 0 (i;-16;0)
-- start block
-- Set bottom screen brightness to i (bottom;i)
-- Set top screen brightness to i (top;i)
-- Wait for VBL
-- end block
Delete object


In fade_out_obj we gonna do it like this

Event Type: Create
Declare i as Type s8 with a value of 0 (i;s8;0)
Loop i from 0 to 16 (i;0;16)
-- start block
-- Set bottom screen brightness to i (bottom;i)
-- Set top screen brightness to i (top;i)
-- Wait for VBL
-- end block
Delete object

thats it
now just in you're action do create object and done!

Hey, shouldn't it be from 0 to -16 for a fade out, that way the two fades smoothly transition? Im just asking though, im a noob lol :D

You can't loop backwards in DSGM without making a custom for() Loop, the Action is fixed on incrementation (adding), thus going from 0 to -16 is impossible with the Action. If you want to do that, you go from 0 to 16 and Set Brightness to -i.

Thanks :D

You're welcome.

...and i'll stick an example here to make things easier. For some reason, I couldn't make a version where you fade white.

Pretty good. You don't need the fade in at the end because you already have one at the beginning. Also, you didn't specify the layer in the change background actions which could've confused someone.

Here's one without the fade in at the end and one that fades to white.

Edit: it goes kinda fast without the Sleep for 2 seconds at the end but you get the idea. Also, do you see the difference in file sizes between the two? They're almost exactly the same but one's double the size. Weirdddd.

*snip* Nevermind.

Now I'm curious -.-

I was going to say that using WaitForVBL or Sleep is not the best of options since you're dropping frames and it's far better to simply use a loop of an appropriate size for your fading effect, but then I figured that the drop in performance is usually so small that it's mostly negligent.

Thanks! I see how it's done now.

Here's another version. You can press anykey (except for the power button on a DS) to skip the splash screens. This was taken from a PAlib example and it doesn't use sleep.
