# How to use

Add DynamicWaterNode.h, DynamicWaterNode.m, Droplet.png and Droplets.fsh to your project

Add to your scene:

```

- (void)didMoveToView:(SKView *)view {

     self.waterNode = [[DynamicWaterNode alloc]initWithWidth:self.size.width

                                                  numJoints:100

                                              surfaceHeight:kSurfaceHeight

                                                 fillColour:[UIColor colorWithRed:0 green:0 blue:1 alpha:0.5]];

    self.waterNode.position = CGPointMake(self.size.width/2, 0);

    [self addChild:self.waterNode];

}

```

Step the simulation in your scene’s update method. See demo project for an example of a fixed time step implementation

```

[self.waterNode update:dt];

```

Call render: after the simulation has been updated. Only call render once each frame.

```

[self.waterNode render];

```

Making splashes:

```

[self.waterNode splashAtX:100 force:20 width:20];

```

Various properties of DynamicWaterNode can be changed to control the feel of the water. The demo project includes a settings screen where you can alter these to see their effect.
