Animated Sprite

Developing the capability for animated sprites caused me to re-design how an entity is created. Before, you'd ask the engine to create one and return it to you. Well since you already have to have the header file for this and I want to provide the capability of custom updates to the entities, I have to allow the user to subclass the entities. This means the user is responsible for cleaning up it's entities. 

Below is the code for adding a sprite. Each sprite is a frame in a sprite sheet and is looped based on the speed the user wants.

 #include "precomp.hpp"  
 #include "Engine.hpp"  
 #include "Animation.hpp"  
 #include <stdlib.h>  
 int main(int aargc, const char* argv[])  
 {  
   // Setup the window  
   Engine* engine = new Engine("Game Engine Sprite Test", 800,600);  
   // Load a texture  
   int t0 = engine->addTexture("link.png");  
   // Create collision area  
   std::vector<ge::fVertex> square;  
   square.push_back(ge::fVertex(0.0f,0.0f));  
   square.push_back(ge::fVertex(64.0f,0.0f));  
   square.push_back(ge::fVertex(64.0f,64.0f));  
   square.push_back(ge::fVertex(0.0f,64.0f));  
   // Create a collider sprite  
   Animation* link = new Animation();  
   link->setScale(.5f,.5f);  
   link->setTexture(t0);  
   link->setSpeed(200);  
   link->setLoop(true);  
   // StartX, StartY, Width, Height  
   link->addFrame(0,0,120,130);  
   link->addFrame(0,520,120,130);  
   link->addFrame(120,520,120,130);  
   link->addFrame(240,520,120,130);  
   link->addFrame(360,520,120,130);  
   link->addFrame(480,520,120,130);  
   link->addFrame(600,520,120,130);  
   link->addFrame(720,520,120,130);  
   link->addFrame(840,520,120,130);  
   link->addFrame(960,520,120,130);  
   link->addFrame(1080,520,120,130);  
   link->play();  
   // Set link as a collider  
   //link->setCollision(&square, ge::Collision_SOLID);  
   // Add our link as a sprite  
   engine->addSprite(link);  
   //std::vector<Entity*>::iterator it;  
   while(engine->isRunning())  
   {  
     engine->run();  
   }  
   delete engine;  
   engine = NULL;  
 }  

I will have another post explaining the entity class in detail and it's components.
