(Snippet) [Entitype] How to collect a list of any Entity sub-class type

[Botre]

Allows you to group multiple entity types in one list which may or may not allow for more efficient overall traversal cost / filtering.

 

Allows you to access sub-list of RS2Object sub-types such as Wall Decoration, which may allow for more efficient filtering.

 

Examples:

List<Entity> wallRelated = Entitype.collect(this, Entitype.OBJECT_WALL_DECORATION, Entitype.OBJECT_WALL_OBJECT);

List<Entity> playersAndGroundItems = Entitype.collect(this, Entitype.PLAYER, Entitype.GROUND_ITEM);

List<Entity> all = Entitype.collect(this, Entitype.ALL);

		List<Entity> entities = Entitype.collect(ctx, Entitype.OBJECT_ALL, Entitype.NPC, Entitype.GROUND_ITEM);
		if(!entities.isEmpty()) {
			Entity target = entities.get(random.nextInt(entities.size()));
			target.examine();
		}
