I have four Sprites: Ball, Objects, Line and Stars. I defined also categories:
static const uint32_t ballCategory = 0x1 << 0;
static const uint32_t objectsCategory = 0x1 << 1;
static const uint32_t lineCategory = 0x1 << 2;
static const uint32_t starsCategory = 0x1 << 3;
properties:
ball.physicsBody.categoryBitMask = ballCategory;
ball.physicsBody.contactTestBitMask = objectsCategory | starsCsategory;
object.physicsBody.categoryBitMask = objectsCategory;
object.physicsBody.contactTestBitMask = ballCategory;
star.physicsBody.categoryBitMask = starsCategory;
star.physicsBody.contactTestBitMask = ballCategory;
line.physicsBody.categoryBitMask = lineCategory;
line.physicsBody.contactTestBitMask = objectsCategory;
now in my didBeginContact
method (thats ok) :
if( ( contact.bodyA.categoryBitMask & lineCategory ) == lineCategory || ( contact.bodyB.categoryBitMask & lineCategory ) == lineCategory ) {
score++;
scoreLabelNode.text = [NSString stringWithFormat:@"%ld", (long)score];
}
if( ( contact.bodyA.categoryBitMask & ballCategory ) == ballCategory || ( contact.bodyB.categoryBitMask & ballCategory ) == ballCategory ) {
[self gameOver];
}
the other part ( this not works):
if( ( contact.bodyA.categoryBitMask & starsCategory ) == starsCategory || ( contact.bodyB.categoryBitMask & starsCategory ) == starsCategory ) {
score = score + 100;
scoreLabelNode.text = [NSString stringWithFormat:@"%ld", (long)score];
}
Where is my fault? I want: when the ball "contact" the star, i get 100 points.
You have a typo in your code: (starsCsategory)
ball.physicsBody.contactTestBitMask = objectsCategory | starsCsategory;
