Position of a Collision

Questions & Answers

I am using a plug-in that handles collision detection of my sprites in a 2D environment. I would like to access the contact.point in OnCollisionEnter, but cannot seem to find a method to extract the information without calling the OnCollisionEnter. Any thoughts?

Contact points are only reported in OnCollisionEnter/Stay, both occurring in the physics cycle (50 times per second). But if you want to have the contact points available outside these functions, you can make a copy inside them and access the copy in any function:

var contact: ContactPoint; // saved contact point

function OnCollisionEnter(coll: Collision){
    contact = coll.contacts[0]; // save the first contact point
}

Copying the first contact is faster and solves most cases, but you can copy the entire contacts array as well:

var contacts: ContactPoint[]; // contact points saved

function OnCollisionEnter(coll: Collision){
    contacts = coll.contacts; // save contact points
}
