The ExplosionManager is now hooked up and can be used to launch several
explosions at once. For the enemies to launch explosions when they die, they
need access to the manager, which can be passed into the constructor.
EffectsManager _effectsManager;
public Enemy(TextureManager textureManager, EffectsManager
effectsManager)
{
_effectsManager ¼ effectsManager;
The enemy can now set off an explosion when it dies.
private void OnDestroyed()
{
// Kill the enemy here.
_effectsManager.AddExplosion(_sprite.GetPosition());
}
In the Level.cs file, the EffectsManager needs to be passed into the Enemy
constructor. Once this is done, shooting the enemy a couple of times in the game
will cause an explosion when the enemy is destroyed.
