Methods Set of programming statements executed by object. 1.4 Methods Set of programming statements executed by object. Methods commonly result in object performing action. My first method

NOTE: how objects are named! This is called “camel case” 1.4 Methods Objects made of other objects Snowman made of: head topHat leftEye rightEye carrotNose mouth leftArm rightArm bottom NOTE: how objects are named! This is called “camel case”

Tasks Compete the following Ch1 Tutorials …. See the scanned Textbook files on Mr. Smith’s website for pages needed for each task. Tutorial 1-2 – Creating a world and adding objects pages 19-30 Tutorial 1-3 – Moving the camera in 3d space, pages 34-35

3D Objects and the Camera 1.6 3D Objects and the Camera Alice world and objects are three-dimensional Height Width } These dimensions are part of 2D objects Depth

1.6 3D Movement Forward is perceived as the object getting larger as it gets closer to us. Backward is perceived as the object getting smaller as it gets farther away from us. Motion is based on OBJECT’s perspective…our left is the Coach’s right

Tasks Compete the following Ch1 Tutorials …. See the scanned Textbook files on Mr. Smith’s website for pages needed for each task. Tutorial 1-4 – Manipulating objects in 3d space, pages 40-43 Tutorial 1-5 – Manipulating subpart objects, pages 43-46

End Of Chapter Programs… Access the scanned textbook pages or get a textbook from the cabinet. Go to pages 54-56 Complete 5 of the exercise from 1-7 and 4 exercises from #8-#13 to showcase chapter 1 skills in Alice.

End Of Chapter Program Design Use one of the templates for your ground color and setting(grass, sand, etc) Create an accident scene that promotes “Don’t Text and Drive” Use the 3-D Text object-scroll to the far right of gallery to enter the text “Don’t Text and Drive” Include a police car, fire truck, people and other objects to create your scene.
