Creating Rule Generators

You can create a rule generator by creating a class called RuleGenerator which inherits from core.generator.AbstractRuleGenerator class. This class should implement two essential methods:

• public RuleGenerator(SLDescription sl, ElapsedCpuTimer time): This is the constructor of the rule generator.
• public String[][] generateRules(SLDescription sl, ElapsedCpuTimer time): This function is responsible returning the interaction rules and termination rules.

All functions are provided with the same two objects:

• Sprite Level Description (SLDescription) object: is a description object that provides the user with functions to retrieve information about the current level and the associated sprites. It provides the user with function to test rules and termination conditions. Follow this link for more information about SLDescription.
• Elapsed Cpu Timer (ElapsedCpuTimer) object: is a timer object that provides the amount allowed for this function.

The generateRules function should return a 2 arrays of string. The first is an array of the interaction rules in the generated game. The second is an array of the termination conditions in the generated game.
