7,937 PointsSpritekit: NSInteger score vs NSInteger *score
I had a bug in my Spacecat game and the score was going up by multiples of 400 instead of 100 as it was supposed to be even though the PointsPerHit was set to 100. It was because I defined the property as NSInteger *score instead of NSInteger score.
Could anyone tell me why it would multiply the points by 4?

162 PointsBecause when you use the ( * ) you are saying you want a pointer to an NSInteger not an NSInteger.
When you do something like
NSInteger myInt; myInt ++; // Complier reads this as myInt = myInt + 1;
But when you do NSInteger *myInt; myInt++; // Complier reads this as myInt = myInt + 4; This is because an NSInteger takes four bytes in memory up and pointers are memory locations.
