What is on collision enter in Unity?
OnCollisionEnter is an event: Unity calls it when the object (which must have a Rigidbody) collides with any collider. This event may occur in both objects, the rigidbody and the hit object.
What is EDGE Collider Unity?
The Collider’s shape is a freeform edge made of line segments that you can adjust to fit the shape of a Sprite. If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development.
What do you mean by edge Collider in Unity?
The Edge Collider__An invisible shape that is used to handle physical collisions for an object. A collider doesn’t need to be exactly the same shape as the object’s mesh – a rough approximation is often more efficient and indistinguishable in gameplay. 2D__ component is a Collider for use with 2D physics.
Can a collider form a straight line in Unity?
The Collider’s start and end points do not need to meet and completely enclose an area (unlike the Polygon Collider 2D ), and can form a straight line or other single edge shape. Select the Edit Polyline button (polyline icon) to make the collider outline editable.
What do you need to know about the edge Collider?
Edge Collider 2D. The Edge Collider__ An invisible shape that is used to handle physical collisions for an object. A collider doesn’t need to be exactly the same shape as the object’s mesh – a rough approximation is often more efficient and indistinguishable in gameplay. More info See in Glossary 2D__ componentA functional part of a GameObject.
Which is better a polygon or edge Collider?
A collider that has more sides to it, takes longer to process collision events on. The best performance comes from a circle colider. Then slightly worse performance from edge or box colliders. Then the worst performance from polygon colliders. If you have very few of these colliders in your game then you won’t notice any difference.
