* You need to either copy or search and add these components
** HittableComponent
** ContactEffectCreatorComponent
** PhysicsComponent
*** StaticMesh (for static collision)
*** ConvexCompound (for dynamic collision)
* Copy by selecting the object you want to copy from in Type Tree and right click "Copy Components", don't copy ModelComponent and TransformComponent, DO NOT COPY FROM DYNAMIC TO STATIC OBJECT OR FROM STATIC TO DYNAMIC!
* If there aren't similar objects with collision in the game Add by selecting the object you want to add to in Type Tree and right click "Add Component Type", then search the needed components
