Time for action – storing the script

The first task is to read the script, extract the needed functions from it, and store them in a safe place. Then, load the project for the game and add a new class with the following code:

class AIScript {
public:
  QScriptProgram read(const QString &fileName);
  bool evaluate(const QScriptProgram &program, QScriptEngine *engine);
  QScriptValue initFunction;
  QScriptValue heartbeatFunction;
  QScriptValue defendFunction;
};

The reading method can have the same content as the original readScriptFromFile method. The evaluate method looks as follows:

bool AIScript::evaluate(const QScriptProgram &program, QScriptEngine *engine) {
  QScriptContext *context = engine->pushContext();
  QScriptValue activationObject;
  QScriptValue result = engine->evaluate(program);
  activationObject = context->activationObject();
  if(!result.isError()) {
    initFunction = activationObject.property("init");
    heartbeatFunction = activationObject...
