        We are currently on the root level meaning we can only access the "entity" the addon is placed upon. This means that "entity" is either a barrel or a tank.
        It is possible to change its data even at the root level.

        Each instance of "$Entity" has the following properties:
        - positionData
            -> Stores data about the entitie's position and angle, if the entity has a parent the x and y coordinates will be relative to the parents position.
        - physicsData
            -> Stores data about the entitie's collision properties (its size, sides, width, if it is a trapezoid).
        - styleData
            -> Stores data about how the entity is rendered, whether or not its visible, its color and so on.
        - barrelData
            -> This field is only defined if the entity actually is a barrel. It only has the shootingAngle property.
        - parent
            -> If this $Entity instance has been created via a createChild call, then this property stores a reference to its creator / parent. (ONLY DIRECT PARENT!)
        - children
            -> If this entity created children via createChild calls, then this property stores references to those children. (ONLY DIRECT CHILDREN!)
        As well as the following methods:
        - clone(source: $Entity)
            -> Clones the sources position, physics, style and barrelData to the current entity.
        - createChild(isBarrel: boolean)
            -> Creates either a regular object entity or a barrel entity and sets its parent as this entity.
        - defaults()
            -> Sets the default values for position, physics, style and barrelData. Check out the default values in "./dma.js".
        
        Each of the "[...]Data" fields has similarly .clone(source: Self) and defaults() methods.
        
        You may not set the properties of $Entity manually. Instead use the "[...]Data" fields or .clone() / .defaults().
        So don't do this: "someEntity.positionData = someOtherEntity.positionData;", but instead do this: "someEntity.positionData.clone(someOtherEntity.positionData);".
