HipDecisionTree

DecisionTree intuition:

IsVisible: true-> Returns PlayerMovement.run false-> Returns a new branch if is hearing IsHearing: true-> Returns "They're hearing you!" false-> Returns null

Functions receive a void* context for accepting any data You can set true or false results for branches by executing the following code tree.setTrueBranch("IsVisible.no.IsHearing", ConditionResult.create("They're hearing you!");

This will make the true branch result at isVisible(false branch) gets the value of the string.

Basic example on how the decision tree works:

HipDecisionTree playerAI = new HipDecisionTree("Enemy-based PlayerAI");

playerAI.addCondition(Condition("IsVisible", (void* ctx) { PlayerAIDecision* d = cast(PlayerAIDecision*)ctx; writeln("Checking if visible"); return d.isVisible; })); playerAI.setTrueBranch("IsVisible", ConditionResult.create(cast(int)PlayerMovement.run)) .setFalseBranch("IsVisible", ConditionResult.create(Condition("IsHearing", (void* ctx) { PlayerAIDecision* d = cast(PlayerAIDecision*)ctx; return d.isHearing; }) )); playerAI.setTrueBranch("IsVisible.no.IsHearing", ConditionResult.create("They're hearing you!"));

PlayerAIDecision d; d.isVisible = false; d.isHearing = false; ConditionResult res = playerAI.check("IsVisible", &d); if(res.type == ResultTypes._int) { writeln(*cast(int*)res.value); } else if(res.type == ResultTypes._string) { writeln(*cast(string*)res.value); }
