Creating animation images?

[Rifts]

Hey! Can someone please explain to me how to make animations? I don't mean in cocos2d but in general.

for example lets say you want a pig to look like hes walking, do you draw a pig in like 10 different positions or draw it once and make slight modifications to the image? Is there some type of program to help? Sorry I'm just confused as to how people do this.

Thanks

Do a search for sprite sheets, that's a pretty common thing. I'm sure there's an easier way to do it, but I don't know of any programs that will help you make animations. It would be stupid of me to think that there's nothing that could help you make sprite animations somehow. Maybe like a 2D bone animation kind of thing.. But anyway, yeah search sprite sheets and what they are and stuff. That should give you a good start.

I know all about sprite sheets I'm just confused as to how to make the sprites in all the different positions for the sprite sheet.

I'll draw pig in 10 positions, copy all this "pigs" files with transparent background (.png file) to XCode.

Next i'll create Array:

@interface GameClass : UIViewConroller {
   UIImageView *ThePigImageView;
   NSArray *MyPigArray;
}

@property (nonatomic, retain) UIImageView *ThePigImageView;
@property (nonatomic, retain) NSArray *MyPigArray;

...

- (void)viewDidLoad {
    MyPigArray = [NSArray initWithObjects:[UIImage imageNamed:@"ThePigPos1.png"],[UIImage imageNamed:@"ThePigPos2.png"],[UIImage imageNamed:@"ThePigPos3.png"],[UIImage imageNamed:@"ThePigPos4.png"],[UIImage imageNamed:@"ThePigPos5.png"],[UIImage imageNamed:@"ThePigPos6.png"],[UIImage imageNamed:@"ThePigPos7.png"],[UIImage imageNamed:@"ThePigPos8.png"],[UIImage imageNamed:@"ThePigPos9.png"],[UIImage imageNamed:@"ThePigPos10.png"],nil]; // Array With Images

   ThePigImageView.animationImages = MyPigArray; // Set Animation Images
   ThePigImageView.animationDuration = 0.1; // Set Animation Time Interval
   [ThePigImageView startAnimating]; // Run Animation
}

...

That all.

P.S. If something not understand, comment.

thanks panda, the thing I guess I'm having the most problems with is the actual drawing of the image in different positions. I guess its more of an art question then a programming one.

Usually you draw a base sprite and then you do small modifications to create the animation, instead of drawing each sprite from zero. Search for some tutorials on sprite animation
