How to remove relationship from entity?

[wcp1231]

Hi, I use koota in my new game, and I don't know how to remove relationship from entity. I want to use relationships to achieve the selected effect, like this:

const player = world.spawn();
const item = world.spawn();
const Selected = relation({ exclusive: true });

// select item
player.add(Selected(item));

// deselect, bug entity cannot remove relationship
player.remove(Selected);

Any help is appreciated, Thanks!

Hello! A relation always has a target, an entity that it is in a relationship with. So if you add a relation for a specific item, you need to remove it for that same item.

// Select item
player.add(Selected(item));

// Deselect item
player.remove(Selected(item))

If you want to find out what the target entity is you can use targetFor.

const item = entity.targetFor(Selected)

if (item) entity.remove(Selected(item))

Although I do think it should be possible to remove all relations of a kind with a wildcard so I will consider adding that.

Great. I PRed the feature to remove all relations of a kind with a wildcard. When I cut the next release it will go live. #133
