What you will be learning in this Lesson?

In the above Scratch Activity you will be exploring the below concepts in detail


Sprite Direction Manipulation

Manipulating the direction of movement of sprites is very vital in developing a game. In this activity you will be exploring this concept in detail with the ball direction manipulation.

You will learn about angle of attack on a sprite and how to change the direction of a sprite based on the direction of movement of the sprite


Game Physics

Computer animation physics or game physics involves the introduction of the laws of physics into a simulation or game engine, particularly in 3D computer graphics, for the purpose of making the effects appear more real to the observer.

Collision Detection


Collision detection typically refers to the computational problem of detecting the intersection of two or more objects.

With regard to scratch, collision detection is the understanding of the intersection/collision of two or more objects. You will be exploring this concept in the development of this game (between the cat and the mouse)
