/* ID: Object Vector Part 2 By: Michael Simnitt. Purpose: To further progress towards a game core design technique. My attempt here is to build an object factory that can handle massive amounts of entity addition and removals while keeping memory both in check and fast. The next part will randomize creation/deletion of both player and creature type classes. NOTE: I would like to Thank all those who shared code and knowledge across SoloLearn and the web. After searching dozens of sites this is a compilation of the many things I have learned from you. Please feel free to criticize and offer suggestions/help. DEBUG Usage: DEBUG shows debug text on objects output. Set to false to hide this. Mock Usage: (int,bool) @int # of objects to create , @ bool set debug mode for Mock. */ #include //cout, endl #include // operator typeid #include //vectors using namespace std; typedef unsigned long EntityId; EntityId idList; bool DEBUG = false; //component class - still needs work class Component { public: EntityId id; string type; Component(){ if (DEBUG) cout << "\nNEW Component: " << this << endl; } Component* getInfo(){ return this; } ~Component(){ if(DEBUG) cout << "Component Destroyed " << this << " " << id << " " << type << endl; } }; static vector OBJ; //create a vector for object storage //objects class - still needs work class object:public Component{ public: object(){ id = idList++; OBJ.push_back(this); //store this object address inside the vector @ end if (DEBUG) cout << "New Object: " << this << endl; } }; // WpSys- Way-point system class class WpSys{ public: int x; int y; int z; int layer; }; class Creature : public object, public WpSys{ public: Creature(){ type = typeid(this).name(); if (DEBUG) cout << "New Creature: " << this << endl; } }; class Player : public object, public WpSys{ public: Player(){ type = typeid(this).name(); if(DEBUG) cout << "New Player: " << this << endl; } }; //handle object destructions TODO: move to deconstructor void destroy(int id){ cout << "\ndestroying ID: " << id << endl; delete &(*OBJ[id]); OBJ.erase(OBJ.begin()+id); } #define null 0x0; //print- Output the object list void print(){ cout << "\nObject List" << endl; Component*obj = null; for(int n = 0 ; n < OBJ.size(); n++){ cout << " ID: " << n << " Type: " << OBJ[n]->type << " "; if(DEBUG) cout << OBJ[n]->getInfo() << " " << OBJ[n]->id; cout << endl; } } //Mock- Used to simulate object creation void Mock(int cycles, bool debug){ cout << "\n MOCK START \n\n"; bool debugPrev = DEBUG; DEBUG = debug; if (DEBUG){ cout << "\nMock Run Started with params-> DebugMode: " << "ON" << " Cycles: " << cycles << endl; }else{ DEBUG = false; cout << "\nMock Run Started with params-> DebugMode: " << "OFF" << " Cycles: " << cycles ; } Player*player = null; for(int n = 0; n < cycles; n++){ player = new Player; } cout << endl; DEBUG = debugPrev; } int main() { Player*objTest = null; Mock(4,true); // create 4 players with debug mode on print(); //print list of players in vector destroy(3); // destroy player at vector index 3 Creature*creo = new Creature; cout << "\nadded creature: " << creo << endl; print(); destroy(0); print(); DEBUG = true; //turn off debug mode Mock(5,false); //add 5 players with debug mode off print(); return 0; }
