Использовать наследование с флокированием на основе stdvector

В данный момент я работаю над заданием, для которого мне нужно создать систему флокирования с разными подклассами, которые ведут себя по-разному. Я работаю с OpenFrameworks и C ++.
Я довольно новичок в Open Frameworks и C ++.

В качестве основы я использовал этот код:
https://sites.google.com/site/ofauckland/examples/ofxflocking-example

Дело в том, что структура этого кода отличается от того, к чему я привык; создание новых объектов класса с помощью ‘new …’

У меня вопрос, как я могу использовать два стекающихся класса? Для начала, сначала только с другим цветом, например.

Один из подклассов, которые я добавил до сих пор, таков:

class Team1 : public Boid {
public:

Team1(): Boid() {};
Team1(int x, int y): Boid(x,y) {};void draw()
{

}
};

Я использовал виртуальную ничью для ничьи суперкласса Boid и использовал boids.push_back (* new Team1 ()); в настройках и и музедраг. Это дает следующие ошибки:

• ожидаемый тип-спецификатор перед Team1
• ожидаемый ) до Team1
• нет соответствующей функции для вызова std::vector<Boid, std::allocator<Boid> >::push_back(int&)

ВЕСЬ КОД: (весь код находится в одном файле testapp.cpp, чтобы исключить проблемы со связыванием)

//number of boids
const int BoidAmount = 25;

Суперкласс Boid:

class Boid {
public:
Boid();
Boid(int x, int y);

void update(vector<Boid> &boids);
virtual void draw() {};

void seek(ofVec2f target);
void avoid(ofVec2f target);
void arrive(ofVec2f target);

void flock(vector<Boid> &boids);

ofVec2f steer(ofVec2f target, bool slowdown);

ofVec2f separate(vector<Boid> &boids);
ofVec2f align(vector<Boid> &boids);
ofVec2f cohesion(vector<Boid> &boids);

ofVec2f location,direction

,acceleration;

float r;
float attraction;
float maxspeed;
};

Конструкторы:

 //---Constructors(overload)-----------------------------------------
Boid::Boid() {
location.set(ofRandomWidth(),ofRandomHeight());
direction.set(0,0);
acceleration.set(0,0);
r = 3.0;
maxspeed = 4;
attraction = 0.05;
}

Boid::Boid(int x, int y) {
location.set(x,y); //initial location
direction.set(0,0); //initial direction
acceleration.set(0,0); //initial acceleration
r = 3.0;
maxspeed = 4; // initial max speed
attraction = 0.1; // initial max force
}

Подклассы:

class Team1 : public Boid {
public:

Team1(): Boid() {};
Team1(int x, int y): Boid(x,y) {};void draw()
{
// Draw a triangle rotated in the direction of direction
float angle = (float)atan2(-direction.y, direction.x);
float theta =  -1.0*angle;
float heading2D = ofRadToDeg(theta)+90;

ofPushStyle();
ofFill();ofPushMatrix();
ofTranslate(location.x, location.y);

ofRotateZ(heading2D);
ofSetColor(255,255,255,80);

ofEllipse(0, -r*2, 7, 12);
ofBeginShape();
ofVertex(0, -r*2);
ofVertex(-r, r*2);
ofVertex(r, r*2);
ofEndShape(true);
ofPopMatrix();
ofPopStyle();
}
};

class Team2 : public Boid {
public:

Team2(): Boid() {};
Team2(int x, int y): Boid(x,y) {};void draw()
{}

};

Methods:

// Method to update location
void Boid::update(vector<Boid> &boids) {

flock(boids);

direction += acceleration;   // Update direction
direction.x = ofClamp(direction.x, -maxspeed, maxspeed);  // Limit speed

location += direction;
acceleration = 0;  // Reset accelertion to 0 each cycle

if (location.x < -r) location.x = ofGetWidth()+r;
if (location.y < -r) location.y = ofGetHeight()+r;

if (location.x > ofGetWidth()+r) location.x = -r;
if (location.y > ofGetHeight()+r) location.y = -r;
}

//SEEK
void Boid::seek(ofVec2f target) {
acceleration += steer(target, false);
}// A method that calculates a steering vector towards a target
// Takes a second argument, if true, it slows down as it approaches the target
ofVec2f Boid::steer(ofVec2f target, bool slowdown) {
ofVec2f steer;  // The steering vector
ofVec2f desired = target - location;  // A vector pointing from the location to the target

float d = ofDist(target.x, target.y, location.x, location.y); // Distance from the target is the magnitude of the vector// If the distance is greater than 0, calc steering (otherwise return zero vector)
if (d > 0) {

desired /= d; // Normalize desired

// Two options for desired vector magnitude (1 -- based on distance, 2 -- maxspeed)
if ((slowdown) && (d < 100.0f)) {
desired *= maxspeed * (d/100.0f); // This damping is somewhat arbitrary
} else {

// Steering = Desired minus direction
