Unity Certification questions with correct answers
Raycast - Correct Answer-This locates Colliders along the path of a ray mesh filter - Correct Answer-The component that takes a mesh from your assets and passes it to the Mesh Renderer for rendering on the screen mesh renderer - Correct Answer-A mesh component that takes the geometry from the Mesh Filter and renders it at the position defined by the object's Transform component mesh collider - Correct Answer-Checks every individual polygon in an object to see if it has collided with anything in the scene. it is the most accurate collider type collider - Correct Answer-An invisible shape that is used to handle physical collisions for an object. A _______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. IsTrigger - Correct Answer-You check this box on a collider component to make it check to see when something Enters the bounding box of the collider trigger - Correct Answer-The scripting system can detect when collisions occur and initiate actions using the OnCollisionEnter function. However, you can also use the physics engine simply to detect when one collider enters the space of another without creating a collision. A collider configured as a ________ (using the Is ______ property) does not behave as a solid object and will simply allow other colliders to pass through. When a collider enters its space, a ________ will call the On_______Enter function on the ________ object's scripts.
rigidbody - Correct Answer-A component that allows a GameObject to be affected by simulated gravity and other forces. material - Correct Answer-An asset that defines how a surface should be rendered, by including references to the Textures it uses, tiling information, Color tints and more. albedo - Correct Answer-The _______ parameter controls the base color of the surface and has no lighting data smoothness - Correct Answer-Material Property: spreading of light on a microsurface detail A smooth surface has very low microsurface detail, or none at all, so light bounces off in uniform ways, creating clear reflections.

In games and apps, ________s are often used describe some of the fundamental properties such as the position of a character, the speed something is moving, or the distance between two objects. point - Correct Answer-infinitely small location in space vertex - Correct Answer-A point where two or more straight lines meet. line - Correct Answer-a straight one-dimensional figure that has no thickness and extends endlessly in both directions edge - Correct Answer-The line along which two surfaces of a solid meet. polygon - Correct Answer-A closed figure formed by three or more line segments in games, it is sort of just a face on an object
ProBuilder - Correct Answer-package in unity that you can build ramps with and stuff texture - Correct Answer-An image used when rendering a GameObject, Sprite, or UI element. _________s are often applied to the surface of a mesh to give it visual detail. pixel - Correct Answer-Short for "picture element" it is the fundamental unit of a digital image, typically a tiny square or dot which contains a single point of color of a larger image.
