engine_rulelist.cs

// call engine rule to get a list of rule info
// to get to know reward to get from executing such action on Engine api
EngineApi.RuleInfoList(Playbasis.Instance, "comment", "jontestuser",

				// loop through all rule
				foreach (RuleInfoVariant2 ruleInfo in result)
				{
					// loop through all jigsaw of each rule
					foreach (Jigsaw jigsaw in ruleInfo.JigsawSet) {

						// if such jigsaw's category is "REWARD", then we know we got a reward here
