Drop system

Drop system is made easily with three nodes:

  • Drop
  • Drop2D
  • Drop3D

Drop

Drop is the node responsible to actuate a drop. A drop consist in spawning a number n of Item resources in a 2D or 3D world.

To setup, it requires a DropTable resource and a path to the owner which drops. The path is the most important part since, if it inherits from Node2D, the drop will try to occur in a 2D world, 3D otherwise if it inherits from Node3D.

Once the Drop.drop_items method is called, the system will lookup for the nearest Drop2D or Drop3D node in the world and append the dropped Items' scenes into it.

Note that all dropped items will inherit the Drop owner's position (the one specified as the Owning Node Path property owning_node_path).

Once the items are dropped in a Drop2D or Drop3D, the signal item_dropped is emitted by one of these nodes. The arguments passed to the signal callback are Item and the related Node2D or Node3D corresponding to the Item.scene property.
