i tryed to use some additive blending with sprites and didnt see anything changed.
what's im doing wrong ?

example 1¶

CCSprite someSprite = CCSprite.spriteWithFile("someImage");
someSprite.BlendFunc.src = OGLES.GL_ONE; //also tryed GL_SRC_ALPHA
someSprite.BlendFunc.dst = OGLES.GL_ONE;
addChild(someSprite);

example 2¶

CCSprite someSprite = CCSprite.spriteWithFile("someImage");
ccBlendFunc someBlend = new ccBlendFunc();
someBlend.src = OGLES.GL_ONE; //also tryed GL_SRC_ALPHA
someBlend.dst = OGLES.GL_ONE;
someSprite.BlendFunc = someBlend;
addChild(someSprite);
