Class CollisionContact

Object that contains the details about a contact.

Values of this instance change with every call to scan(...) so it's not meant for you to keep.

CollisionContact objects are part of an internal object pooling. This is a measure to reduce the pressure on the garbage collector.

const contactsA = collision.scan(myScanShape);       // 1st scan
const contactsA_copy = contacts.map(c => c.copy());  // copy for later use
const contactsB = collision.scan(myScanShape);       // 2nd scan

console.log(contactsA);      // <- BAD! Random data because of 2nd scan
console.log(contactsA_copy); // <- OK!
console.log(contactsB);      // <- OK, because it's data from the last scan
