#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);
