Artemis C++
===
A C++ port of [Artemis Entity System Framework](http://gamadu.com/artemis/tutorial.html).
The port was orignially written by [Sidar Talei](https://bitbucket.org/stalei/artemiscpp/src), in which he used several C++11 features such as deleted function, variadic templates, nullptr, etc…
We wanted the framework to be portable, so we removed all C++11 feature usages.
### PORTED CLASSES
- Component
- ComponentMapper
- ComponentType
- ComponentTypeManager
- Entity
- EntityProcessingSystem
- EntitySystem
- SystemBitManager
- ImmutableBag
- EntityManager
- DelayedEntityProcessingSystem
- DelayedEntitySystem
- GroupManager
- IntervalEntityProcessingSystem
- IntervalEntitySystem
- Manager
- SystemManager
- TagManager
- utils
- World
- Bag
### EXAMPLE
`VelocityComponent` and `PositionComponent`.
``` cpp
class VelocityComponent : public artemis::Component {
public:
float velocityX;
float velocityY;
MovementComponent(float velocityX, float velocityY)
{
this->velocityX = velocityX;
this->velocityY = velocityY;
};
};
class PositionComponent : public artemis::Component
{
public:
float posX;
float posY;
PositionComponent(float posX, float posY)
{
this->posX = posX;
this->posY = posY;
};
};
```
MovementSystem updates positions base on velocities
``` cpp
class MovementSystem : public artemis::EntityProcessingSystem {
private:
artemis::ComponentMapper velocityMapper;
artemis::ComponentMapper positionMapper;
public:
MovementSystem() {
addComponentType();
addComponentType();
};
virtual void initialize() {
velocityMapper.init(*world);
positionMapper.init(*world);
};
virtual void processEntity(artemis::Entity &e) {
positionMapper.get(e)->posX += velocityMapper.get(e)->velocityX * world->getDelta();
positionMapper.get(e)->posY += velocityMapper.get(e)->velocityY * world->getDelta();
};
};
```
Usage:
``` cpp
int main(int argc, char **argv) {
artemis::World world;
artemis::SystemManager * sm = world.getSystemManager();
MovementSystem * movementsys = (MovementSystem*)sm->setSystem(new MovementSystem());
artemis::EntityManager * em = world.getEntityManager();
sm->initializeAll();
artemis::Entity & player = em->create();
player.addComponent(new MovementComponent(2,4));
player.addComponent(new PositionComponent(0,0));
player.refresh();
PositionComponent * comp = (PositionComponent*)player.getComponent();
while(true){
world.loopStart();
world.setDelta(0.0016f);
movementsys->process();
std::cout << "X:"<< comp->posX << std::endl;
std::cout << "Y:"<< comp->posY << std::endl;
Sleep(160);
}
return 0;
}
```
### LOGS
- Dec 10, 2012:
- [Fixed bug](https://github.com/vinova/Artemis-Cpp/commit/449ee9d3167d6bdf8056a8da7554ebec016e5b65): calling Bag.get(index) not returning NULL when index > bag's size,
which leads to memory violation when the number of entities becomes greater than initialized entities bag size.
- Nov 15, 2012:
- [Fixed bug](https://github.com/vinova/Artemis-Cpp/commit/fe291598b699cd283fc029ee727669b8e7a76e24): memory leak when add a component to an entity
who already had this component.
- Sept 11, 2012:
- [Fixed critical bug](https://github.com/vinova/Artemis-Cpp/commit/731d2c3e6f4afbd32e4d33f08f23373d62b91dd9): deleting World doesn't delete/reset all neccessary data,
which will lead to memory violation when a World is deleted and a new one is created.
- Sept 12, 2012:
- Removed all C++11 feature usages.
