SpriteBar - Draw your own progress bar in Sprite Kit.

This library is a convenient way to create your own SKSpriteNode progress bars in Apple's Sprite Kit. Simply pass in a Texture Atlas containing your sprites and SpriteBar will do the rest.

Features

• Progress bar generation from SKTextureAtlas.
• Automatically scales the animation, allowing you to provide as many frames as you want. From 2 to 100!
• Finds the closest texture file to the percent provided.
• Built in timer function starts animating the progress bar with your graphics.

Installation

Simply drag the SpriteBar folder into your project and use #import "SpriteBar.h". Make sure you have followed the naming convention for your texture frames: (you may specify a texure reference to replace progress using textureReference)

progress_10.png
progress_20.png
progress_30.png
etc

Usage

// Init and add
SpriteBar *progressBar = [[SpriteBar alloc] initWithTextureAtlas:myCustomTextureAtlas];
progressBar.size = CGSizeMake(50, 50);
[self addChild:progressBar];

[progressBar setProgress:0.2];
// or
[progressBar setProgressWithValue:36 ofTotal:200];
// or
[progressBar startBarProgressWithTimer:10 target:self selector:@selector(timeOver)];
