Overview

The class programs their sprites to interact in new ways. After a brief review of how they used the isTouching block, the class brainstorms other ways that two sprites could interact. They then use isTouching to make one sprite push another across the screen before practicing with the four collision blocks (collide, displace, bounce, and bounceOff).

Vocab

• Abstraction - a simplified representation of something more complex. Abstractions allow you to hide details to help you manage complexity, focus on relevant concepts, and reason about problems at a higher level.

New Code

• sprite.bounce(target)
• sprite.bounceOff(target)
• sprite.collide(target)
• sprite.displace(target)
• setCollider(type, xOffset, yOffset, width/radius, height, rotationOffset)
• sprite.bounciness
