Useful functions

Add new component

KapEngine include component system. Because of this system, you can add components in your GameObject. To do that you have this function :

addComponent(std::shared_ptr<Component>);

Get contains component

If you can add components, you can get all components that GameObject contains. For that you can use these functions :

/* KapEngine 1.0 */
Component &comp = getComponent("ComponentName");
/* Since KapEngine 1.1.02 */
MyComponent &comp = getComponent<MyComponent>();

getComponent("ComponentName"), will disappear in next versions. Prepare your code

You can also get all same components in one GameObject since KapEngine 1.2.1 :

/* Since KapEngine 1.2.1 */
std::vector<std::shared_ptr<MyComponent>> components = getComponents<MyComponent>();

Remove component

If you can add components, logically you can remove components. To do that, you can use this function :

/* if you component is shared_ptr */
removeComponent(myComponent);

/* if your component is reference or other */
removeComponent(myComponent.getId());

Check contains component

You can check if your GameObject contains a specific component with the function below :

/* KapEngine 1.0 */
bool result = hasComponent("ComponentName");
/* KapEngine 1.2 */
bool result = hasComponent<MyComponent>();

Check GameObject is active

You can also check if your GameObject is active by this function :

bool result = isACtive();

Get scene

As you can read in scene category, scenes are one of main system in KapEngine. Because of GameObjects are stock in scene, you can get the scene where your GameObject is stock with this function :

SceneManagement::Scene &scene = getScene();
