Getting Started

This is assignment is a followup to Lab 13. You probably want to finish reading Chapter 7 of Eloquent JavaScript before doing the assigment, as it is related to the two exercises given there.

Start with the following the following JavaScript code, save it to ~fcshome/cs2613/assignments/A4.

• life.js a solution to Lab 13
• life.spec.js a solution to Lab 13 (tests)
• moarlife.js new code for this assignment (from the book)
• moarlife.spec.js tests for the above
• valley.js animation

Since your assignment will involve modifying an existing codebase, make sure that your git commits reflect a logical sequence of changes.

• Update the tests to provide full line and branch coverage, according to nyc jasmine. In my solution this involves adding two tests.

• Make an ExplodingBunnyRabbit class based on PlantEater that explode if they eat too much. More precisely, if their energy exceeds 55, their act method should return an action of type "die" 25% of the time; otherwise it should behave like a PlantEater. For full credit, use extends.

• Add tests for ExplodingBunnyRabbit similar to those of PlantEater. Copy and paste is OK here, although you'll need to make some changes.

• Initially the 'die' returned by the ExplodingBunnyRabbit is ignored. Update actionTypes so that the 'die' event is handled by replacing the current rabbit with a piece of wall. As a hint, you'll have to somehow make sure you get the right 'originChar' for the new piece of wall.

• Update your tests for complete coverage.
