Review of hit testing concepts
- [Instructor] If you're not new to Unreal development, you're familiar with HIT testing and what that means. And if so, feel free to skip this video. In short, HIT testing is whenever an object in the world hits an object, or is hit by something else in our scene. It is a concept used throughout the Unreal Engine world and not exclusive to AR. So if we have a T-Rex that races through a level and then hits another player or object in our scene, it is a HIT, and therefore an event where something else needs to happen. This is where blueprints or code come handy where if we hit something, something else happens. So if we hit another object then we could get points, damage, et cetera. For anyone who played a game in the past, this isn't a new concept. The same concepts could apply to AR, where HIT event generates another. So if we applied this to AR it would simply mean whenever we touch the screen something happens, like a random object is dropped. And this is exactly what we'll do in this course.
