## Exercise to Engage the Code
|
||
|
|
|
||
|
|
These are questions that ask you to explore the code in a specific way. They highlight important functionality and flow-of-control. You might want to jot down the answers for your own use as you spend time learning the code. It will probably take you a minimum of 2 hours just to understand how all the pieces fit together. We highly recommend you spend time understanding the framework before adding a single line of code.

# Answer the Following Questions Based on Iteration1 Code
|
||
|
|
|
||
|
|
1. What does GraphicsArenaViewer::DrawUsingNanoVG() do?
|
||
|
|
2. When does this get called?
|
||
|
|
3. How is it that the Recharge Station is being drawn - there is no command to draw it?
|
||
|
|
4. What entities exist in the Arena?
|
||
|
|
- For each entity, what is it's base (parent) class?
|
||
|
|
|
||
|
|
5. Where does the system check for collisions (look in Arena.cc)?
|
||
|
|
6. When does this happen (i.e. where is it in flow-of-control)?
|
||
|
|
7. What is the logic for checking for colliding with walls?
|
||
|
|
8. What is the logic for checking for colliding with other entities?
|
||
|
|
9. Trace the EventCollision from the point at which it is created in Arena to
|
||
|
|
the robot sensor. What does the sensor record when a collision happens?
|
||
|
|
10. The RobotMotionHandler reads the touch sensor. What does it do with this information?
|
||
|
|
11. Identify the method (function) that updates the robot position. Trace flow-of-control
|
||
|
|
from the call UpdateSimulation in GraphicsArenaViewer.
|
||
|
|
12. What is the equation used to calculate the deltaX and deltaY for the robot
|
||
|
|
and update the position?
