I wonder if there is a tool that could be used for easy generation of complex physics bodies in SpriteKit. I would like to have a volume based physical bodies with polygon-t
You can just do this now to generate physics body from your sprite's PNG:
SKSpriteNode *yourPhysicsSprite = [SKSpriteNode spriteNodeWithImageNamed:@"yourPNG"];
yourPhysicsSprite.physicsBody = [SKPhysicsBody bodyWithTexture:yourPhysicsSprite.texture alphaThreshold:0.0f size:yourPhysicsSprite.texture.size];
Less precise and perhaps more costly than doing by hand, but works fine.
