Tile animation

[Jam0864]

I was doing the SGDK tutorial, and when I finished I started adding to the game. I've improved the graphics, made the player sprite animated and created hills. I was thinking of making the stars you pick up rotate, to make the them look less 'plain'. So how do you make an animated tile in SGDK2?

With the Tileset Editor.  Try this and let me know if the help page is enough for you to figure out the Tileset Editor:

cool, that works. But now I can't manage to allow the player to pick-up the stars. (Since the tile index is always changing) Is there a way I can let the player pick-up the stars?

[bluemonkmn]

The tile index doesn't change, just the frame displayed by that tile index.

[Jam0864]

Well, the stars aren't getting picked up.

Here's my version of the tutorial project updated to make a rotating star.  The only trick was adding rules to increment the counter.  Everything else was pretty straightforward.  Are you still using the same tile number?  Check my project and see how it compares to yours.

It turned out my problem was I had the tile index as 258 instead of 238 in my 'pick up stars' rule. And no I wasn't using the same tile number because I wanted stars to be animated on the map but normal in the inventory. So the inventory used the unanimated tile index (2) while the map had the animated one. (238)
Since this topic is on animation I might as well ask my next question here, instead of starting a new topic. How would you have a rotating sprite that has an animated 'flames' state when pressing a certain button and go back to the normal state when not pressing the button? (I'm putting nitrous on a car)

[bluemonkmn]

If you have 72 states where the first 72 are wouthoug flames and the second 72 are with, then you would need to detect when the button is pressed and the state is less than 72.  In that condition, you'd need to add 72.  Then also detect when the button isn't pressed and the state is >= 72.  In that case subtract 72 from the state.

[Jam0864]

I have 360 states and i was thinking, is there an easier way to add frames to states rather than dragging them in individually? 360 states might take a while.

EDIT

Don't worry I just figured out how.

[Jam0864]

That's working great!  Thanks

Well, don't leave everyone else in the dark, tell them you used the rotating sprite wizard (right?)

[Jam0864]

Yeh, I used the rotating sprite wizard. I just scanned through the writing the first time and never actually read it until now. It's quite obvious how to do it if you take the time to read the instructions.
