#Cocos2D-Mask-Shader

##Mask sprite with OpenGL ES 2.0 shader in Cocos2D (Adapted from https://github.com/HarrisonJackson/Cocos2D-HJMasked-Sprite)

Branches :

• master : Cocos2D 2.1 support
• Cocos2D-2.0-support : https://github.com/tonybeltramelli/Cocos2D-Mask-Shader/tree/Cocos2D-2.0-support

Getting started :

• Copy the files of the src folder into your project;
• Don't forget to add the .fsh files to the "Copy Bundles Resources" in "Build Phases" tab;
• Make sure that the .fsh files are not in the "Compile Sources";

Usage :

        // EXAMPLES MaskNegative
        //
        // example 1
        
        CCSprite *spriteToMask = [CCSprite spriteWithFile:@"image_to_mask.jpg"];
        CCSprite *spriteMask = [CCSprite spriteWithFile:@"mask.png"];
        
        TBSpriteMask *maskedSprite = [[TBSpriteMask alloc] initWithSprite:spriteMask andMaskSprite:spriteToMask];
        [self addChild:maskedSprite];
        
        // example 2
        
        CCSprite *spriteMask = [CCSprite spriteWithFile:@"mask.png"];
        
        TBSpriteMask *maskedSprite = [[TBSpriteMask alloc] initWithSprite:spriteMask andMaskFile:@"image_to_mask.jpg"];
        [self addChild:maskedSprite];
        
        // example 3
        
        CCSprite *spriteToMask = [CCSprite spriteWithFile:@"image_to_mask.jpg"];
        
        TBSpriteMask *maskedSprite = [[TBSpriteMask alloc] initWithFile:@"mask.png" andMaskSprite:spriteToMask];
        [self addChild:maskedSprite];
        
        // example 4
        
        TBSpriteMask *maskedSprite = [[TBSpriteMask alloc] initWithFile:@"mask.png" andMaskFile:@"image_to_mask.jpg"];
        [self addChild:maskedSprite];
        
        //
        // EXAMPLES MaskPositive
        //
        // example 1
        
        CCSprite *spriteToMask = [CCSprite spriteWithFile:@"image_to_mask.jpg"];
        CCSprite *spriteMask = [CCSprite spriteWithFile:@"mask.png"];
         
        TBSpriteMask *maskedSprite = [[TBSpriteMask alloc] initWithSprite:spriteMask andMaskSprite:spriteToMask andType:TRUE];
        [self addChild:maskedSprite];
        
        // example 2
        
        CCSprite *spriteMask = [CCSprite spriteWithFile:@"mask.png"];
         
        TBSpriteMask *maskedSprite = [[TBSpriteMask alloc] initWithSprite:spriteMask andMaskFile:@"image_to_mask.jpg" andType:TRUE];
        [self addChild:maskedSprite];
        
        // example 3
        
        CCSprite *spriteToMask = [CCSprite spriteWithFile:@"image_to_mask.jpg"];
         
        TBSpriteMask *maskedSprite = [[TBSpriteMask alloc] initWithFile:@"mask.png" andMaskSprite:spriteToMask andType:TRUE];
        [self addChild:maskedSprite];
         
        // example 4
        
        TBSpriteMask *maskedSprite = [[TBSpriteMask alloc] initWithFile:@"mask.png" andMaskFile:@"image_to_mask.jpg" andType:TRUE];
        [self addChild:maskedSprite];
        
        //
        // EXAMPLES update
        //
        // example 1
        
        CCSprite *spriteMask = [CCSprite spriteWithFile:@"mask.png"];
        [maskedSprite updateWithSprite:spriteMask];
        
        // example 2
        
        [maskedSprite updateWithFile:@"mask.png"];

        //
        // Create sprite with resulting texture
        //

        CCSprite *resultingSprite = [CCSprite spriteWithTexture:[_maskedSpriteNegative getTexture]];
        resultingSprite.scale = 0.5;
        resultingSprite.position = ccp(size.width/2, size.height/2);
        [self addChild:resultingSprite];
