Detailed Description

Various methods to control internal aspects of the GameObject.

GameObject entry and exit from a Scene is mostly used when using objects that are created and recycled from an Object Pool For example here is where it would be used for Bullet created/recycled from a Bullet pool. NOTE: this uses collisions for the example see Collision Module for more information about collisions. As well as key inputs, see Input Module for more information about inputs.

// -----------------------------------------------------------------------------------
// Bullet Game Object Set Up
// -----------------------------------------------------------------------------------
Bullet::Bullet()
{
    // Initializing Bullet Graphics Object and other settings
    // Set up collision for bullet
}
 
void Bullet::sceneEntry()
{
    //NOTE: This is where registration for update, draw, inputs, and collision should occur
    GameObject::submitUpdateRegistration();
    GameObject::submitDrawRegistration();
    GameObject::submitCollisionRegistration();
}
 
void Bullet::sceneExit()
{
    //NOTE: This is where deregistration for update, draw, inputs, and collision should occur
    GameObject::submitUpdateDeregistration();
    GameObject::submitDrawDeregistration();
    GameObject::submitCollisionDeregistration();
 
    // In this example since the Bullet was created by the pool, 
    // we return it back to the pool
    BulletPool::ReturnBullet(this);
 
}
 
void Bullet::collision(Tank*) // Collision with tank object
{
    GameObject::submitSceneExit();
}
 
// -----------------------------------------------------------------------------------
// Tank Game Object Set Up
// -----------------------------------------------------------------------------------
Tank::Tank()
{
    // Submit Key registration
}
 
void Tank::keyPress(AZUL_KEY key)
{
    if(key == AZUL_KEY::SPACE) // Fire key
    {
        // Get bullet from Bullet Pool
        Bullet* pBullet = BulletPool::GetBullet();
 
        Vect bulletPosition = computeBulletSpawnPosition();
        Vect bulletDirection = computeBulletDirection();
        pBullet->initialize(bulletPosition, bulletDirection);
 
        // Submit scene entry;
        pBullet->submitSceneEntry();
    }
}
