/// \brief Used to apply damage to objects in the vicinity and push physical objects away.
///
/// The component queries for dynamic physics shapes within a given radius.
/// For all objects found it sends the messages ezMsgPhysicsAddImpulse and ezMsgDamage.
/// The former is used to apply a physical impulse, to push the objects away from the center of the explosion.
/// The second message is used to apply damage to the objects. This only has an effect, if those objects
/// handle that message type.///
///
/// This component is mainly meant as an example how to make gameplay functionality, such as explosions.
/// If its functionality is insufficient for your use-case, write your own and take its code as inspiration.
