Custom properties of entities

[christopho]

Allow to add any property (key and value) to any type of entity.

This is great. I was thinking in a feature like this a few days ago.

I am not sure but, shouldn't this be in the Editor's repo?

[christopho]

Yes but the engine still has to support the updated data file format and to provide a Lua API to get/set properties.

Awesome stuff!

[Diarandor]

Will these properties appear as a parameter for the creation event? I mean: entity:on_created(properties_list).

Or there will be a specific function to recover the list of properties? I mean: entity:get_initial_properties().

[christopho]

There will be entity:get_property() and entity:set_property().
Or entity:get_field()/entity:set_field(), I am not sure :)

[Diarandor]

I think it could be convenient to allow to recover that list somehow, or at least the list of keys.
For instance, if we want to make a script that clones entities (of many types), we cannot know which were the initial properties because we cannot access that info.

[CJBok]

I would vote for entity:get_property() and entity:set_property().

Also can the same be done on the actual map as well? Would be nice to have extra properties on the map as well :)

@CJBok: I think so. The issue seems to me not only about the engine, but also about the Map Editor, as it can be seen in the attached image.
