Detecting a Solved Puzzle

This section shows how to detect when the player solves the puzzle by finding the right combination of lights. When the puzzle is solved, the Item Spawner device should be enabled so that it can spawn its item.

Follow these steps to detect when the player solves the puzzle:

1. Add an editable item_spawner_device field named ItemSpawner to the tagged_lights_puzzle class, to represent the Item Spawner device.

   
   
   |  | @editable |
   | --- | --- |
   |  | ItemSpawner : item_spawner_device = item_spawner_device{} |

2. Next, define what state the lights should be in to solve the puzzle. Since the representation of the lights’ state is a logic array, the solved state of the lights should also be a logic array to easily compare the two. Create an editable logic array field named SolvedLightsState to the tagged_lights_puzzle class. In this example, the player must turn on all the lights to solve the puzzle, so initialize each element with the value true to represent the light being on.
