Creating Components

• Add a new class that inherits from ComponentEntity - and it will show as a add option ingame

• Entity Components are Unity MonoBehaviors, so Awake / Start / Update / FixedUpdate can all be used

• If using Awake, it needs to be overridden and and base.Awake() called- since the base component's Awake method needs to run

There are a few Modbox specific virtual methods that can be used:

• AfterAddedToWorld - Called after the Entity was added to World and Awake is called
• RefreshComponents - Called after added to world and whenever components are changed on the Entity. This is where any components should be set.
• SavedDataLoaded - Called after the Entity loads it's data, if it's saved in the world
• RefreshValuesBefore - If the component has values that can be changed by other components, it should 'refresh' them and clear them.
• RefreshValuesAfter - Where a component should change other components values (that got cleared in RefreshValuesBefore)
• OnPlaymodeStarted - Called on starting play mode but before Physics body created
• OnPlaymodeAfter - Called after physics body created and play mode started

Use 'GetComponentEntity' rather than 'GetComponent' - since components can also be added to the Entity by child gameobjects in some cases (like if the entity has a Humanoid Models with Components)

[MBDescription("Draws a Line to show the Spring Joint.")]
    [MBTypeComponentEnabledInEditmode]
    [MBTypeRequireComponents(typeof(EntSpringJoint))]
    public class EntSpringJointLine : ComponentEntity
    {
        [MBValueOnChangedMethod(nameof(OnChange_Enabled))]
        [MBValueDefaultValue(true)]
        public BoolVariable Enabled { get; private set; }

        [MBValueOnChangedMethod(nameof(OnChange_Color))]
        public ColorVariable Color { get; private set; }

• Use 'MBTypeRequireComponents' - not Unity's 'RequireComponent', to set what other components are required for the component type

• MBTypeComponentEnabledInEditmode is used so that the Update/Start methods are run in edit mode. By default Entity components are disabled in edit mode.
