Game Event Editor Preliminary analysis and implementation (2)

The next step is to build the event class with the event Manager:

First, consider how an event is categorized, using virtual functions and inheritance.

The constructed event classes are as follows:

Class event{

BOOL eventcontroller* Evencontroller ();

BOOL conditioncontroller* Conditioncontroller ();

void actioncontroller* Actioncontroller ();

void Check () {

if (Eventcontroller->fucntion ())

if (Conditioncontroller->function ())

Actioncontroller->function ()

}

};

Class eventcontroller{

Public

virtual bool Function ();

};

Class conditioncontroller{

Public

virtual bool Function ();

};

Class actioncontroller{

Public

virtual void Function ();

};

For example, in the example above, we have to inherit Eventcontroller,conditioncontroller and Actioncontroller three classes separately:

Class Evententer:public eventcontroller{

Public

Man m;

Region R;

virtual bool Function ()

{

if (M in R)

return true;

return false;

}

};

Class Conditionis:public conditioncontroller{

Public

Man m;

Unit u;

virtual bool Function ()

{

if (M==u.master)

return true;

return false;

}

};

Class Actionattack:public actioncontroller{

Public

Mans &m;

Unit &u;

virtual void Action ()

{

Order u attack m;

}

};

The above variables are defined for public, for ease of operation.

And the event manager is fairly simple

Class eventmanager{

Vector<event> events;

Public

void Checkevents ();

void Addevent ();

...

};

After you have completed these classes, you begin to join the event.

Please see the following code for details:

#include <iostream> #include <Windows.h> #include <time.h> #include <vector> using namespace std ; struct man{int pos;//position int ID; int HP; Man () {pos=0; Id=0; hp=100; } bool Equals (man P) {if (id==p.id) return true; return false;}}; struct unit{man master; Man attacking; }; struct region{int rl,rr;}; Class eventcontroller{public:virtual bool Function () {return 0;}}; Class Evententer:public eventcontroller{Public:man m; Region R; virtual bool Function () {if (R.RL&LT;M.POS&AMP;&AMP;M.POS&LT;R.RR) return true; return false;}}; struct conditioncontroller{virtual bool Function () {return 0;}}; struct conditionis:conditioncontroller{man m; Unit u; BOOL Function () {if (M.equals (U.master)) return true;}}; struct actioncontroller{virtual void Function () {}}; struct actionattack:actioncontroller{man *m; Unit *u; void Function () {}}; struct event{eventcontroller* Eventcontroller; conditioncontroller* Conditioncontroller; actioncontroller* ActioncOntroller; Event (eventcontroller* e,conditioncontroller* c,actioncontroller* a) {eventcontroller=e; conditioncontroller=c; Actioncontroller=a; } void Check () {if (Eventcontroller->function ()) {cout << "A event happened" << Endl; if (conditioncontroll Er->function ()) {cout << "Conditon is Enough" << Endl; cout << "action!" << Endl; actioncontro Ller->function (); } else{cout << "Condition is not Enough" << Endl, cout << "Nothing happened" << Endl;} } }; Class eventmanager{vector<event> Events; vector<event>::iterator t; static eventmanager* instance; EventManager () {} public:static eventmanager* getinstance () {if (instance==null) instance=new EventManager (); return ins tance; } void Addevent (Event e) {events.push_back (e),} void Checkevents () {for (T=events.begin (); T!=events.end (); ++t) {(*t). Check (); }} ~eventmanager () {delete instance;}}; eventmanager* Eventmanager::instance=null; int main () {Man M; Mans p; Unit Dog; Region R; Dog.master=m; p.pos=5; Change the value of POS to debug p.id=1; Change the value of ID to debug r.rl=3; r.rr=10; Srand (Time (0)); Evententer Evententer; Evententer.m=p; Evententer.r=r; Conditionis Conditionis; Conditionis.m=p; Conditionis.u=dog; Actionattack Actionattack; actionattack.m=&m; actionattack.u=&dog; Event e (&evententer,&conditionis,&actionattack); Eventmanager::getinstance ()->addevent (e); Eventmanager::getinstance ()->checkevents (); } 

This completes the design and addition of an event, and if there are more event classes in the game, it is necessary to derive 3 classes such as Eventcontroller. That's probably it.

I don't know how to write an article, maybe some mistakes in the language, please understand.
