How do I correctly use allContactedBodies?

Question

I want to use allContactedBodies instead of didBeginContact & didEndContact.

When I do :

NSLog(@\"%@\", node.physicsBody.allContactedBodies );
<         


        

Answer 1

The allContactedBodies property returns an array of SKPhysicsBody objects. You can access the node to which each physicsBody is attached by using the node property of SKPhysicsBody

NSArray *tempArray = [yourNode.physicsBody allContactedBodies];
for(SKPhysicsBody *body in tempArray)
{
    if([body.node.name isEqualToString:@"theBall"])
        NSLog(@"found the ball");
}

In Swift the same code above can be written like:

val ballNode: SKNode? = yourNode.physicsBody.allContactedBodies().first(where { $0.node.name == "theBall" })?.node
