Adding Physics to Sprites

Problem

You want to make sprites be affected by gravity and other physical forces.

Solution

To make an SKSpriteNode be physically simulated, create an SKPhysicsBody and then set the sprite’s physicsBody property to it:

SKScene* scene = ... // an SKScene SKSpriteNode* sprite = [SKSpriteNode spriteNodeWithColor:[SKColor whiteColor] size:CGSizeMake(100, 50)]; sprite.position = CGPointMake(CGRectGetMidX(scene.frame), CGRectGetMidY(scene.frame)); sprite.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:sprite.size]; [scene addChild:sprite];
