Making it rain in Cocos2d

Read this tutorial to learn how to make it rain using particles in cocos2d.

We begin by adding the rain drop image to our project.

All you have to do is add the code bellow to your init meathod.

[super onEnter];

CCParticleSystem* emitter = [CCParticleRain node];

[self addChild: emitter z:10];

CGPoint p = emitter.position;

emitter.position = ccp( p.x, p.y); = 4;

emitter.texture = [[CCTextureCache sharedTextureCache] addImage: @"Raindrop.png"];

emitter.startSize = 10.0f;

Life is how long the particles in the emitter last. Texture is the image you want the particles to be. StartSize is the size of the particles to begin with. If you would like to see more of what you can do with particles run the particle test that comes with cocos2d.

    This is because this device assures to either benefit or cure
    the autistic people in more ways than one. 20 percent of customers have the potential
    to spend five times as much as they do currently
    A relatively small amount of marketing effort creates the majority of
    output. But it seems Memorial Day wasn’t important enough to Google.

  6. Why don’t we take a good look at exactly how we for instance can transform the eggs
    and milk towards cake of. You can substitute eggs
    with vegan pleasant items for instance agar dust, potato starch, vinegar, flax seeds or agario hack even mashed potatoes.

  7. Clash Royale has a pretty excellent match-making system, and the greater arena you remain in, the better the reward.
    So do not drop prizes simply to combat in a lower arena as the reward isn’t really as huge.
