WaveGenerator

Cocos-2D Class (and Example project) for generating water-like waves in the CCSprite objects.

How to use it?

CCSpriteWaveGenerator class has all the logic to create and update ripple simulation on the CCSprite object you provide.

Step 1:

      //Create CCSprite that you want the ripples applied
      
      CCSprite *sprite = [CCSprite spriteWithFile:@"Default.png"];
      
      //Create and initialized CCSpriteWaveGenerator object
      CCSpriteWaveGenerator* swg = [[CCSpriteWaveGenerator alloc] initWithCCSprite:sprite];

Step 2:

     //You have to keep updating the state of the simulation in your CCLayer's update method

     - (void) update:(ccTime)dt{
          [swg update:dt];
      }          

Step 3:

    //Access the CCSprite with ripple simulation applied to it using property "rippledSprite"
    CCSprite *rippledSprite = swg.rippledSprite;

Step 4:

   //Create waves for some fun!

   CGPoint rippleOrigin = CGPointMake(..,..);
   [swg createWaveAt:rippleOrigin];

Touch Example:

- (void)ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event{
    CGPoint origin = [swg.rippledSprite convertTouchToNodeSpace:touch];
    [swg createWaveAt:CGPointMake(origin.x,origin.y)];
}
