ORK Framework can store component data attached to a combatant’s game object and save it with ORK’s save game system.

This is done by implementing the IComponentSaveData interface in your component’s class.

When will the data be stored/loaded?

The data of all components implementing the IComponentSaveData attached to a combatant’s game object or any of its children will be stored when:

  • the game object is destroyed
  • when a combatant is stored (while the game object is alive) through a Combatant Spawner component (using the Remember Combatants setting)
  • when the game is saved (only for members of the player group), if the combatant’s game object isn’t alive at that time, the stored data (from destroying the game object) will be saved

The data is loaded whenever the combatant’s prefab is spawned or a new game object is assigned as the combatant’s game object.

This can be used to e.g.:

  • save component data with a save game
  • transfer component data between scenes
  • transfer component data when changing prefabs (conditional prefabs)
  • store component data for remembered combatants (Combatant Spawners)

The IComponentSaveData interface

This interface has 3 functions that need to be implemented into your class:

This function returns the save key used to store the data of the component. The save key mustn’t contain any spaces, e.g. save key is not allowed, but save_key is allowed.

Only one component data can be stored per key, i.e. if you want to store multiple components of the same class, you should implement a save key field to define a save key in the inspector of the component and return that key in the function.

This function is called when the component data is stored/saved. It returns a DataObject, which holds all the data that you want to save.

This function is called when a component data is loaded. The DataObject passed as parameter contains the data that is saved. It’s crucial to make a check for null on the data object before using it, since it could be null if no data was found for the save key – in that case, you can use the load game function to do default initialization.

Code example

Here’s a small code example on how the custom component save data functionality can be used.
