world.createComponent to create components without adding them to an entity

[fernandojsg]

Currently is possible to add a component by passing the component class and an object to replace the default values:

entity.addComponent(ComponentA);
entity.addComponent(ComponentB, {value: 23, other: 'test'});

It would be interesting to be able to request a component without adding it to an entity automatically:

var component = world.createComponent(ComponentB);
component.value = 23;
component.other = 'test';

entity.addComponent(component);

// You could still do this the "old" way
entity.addComponent(ComponentA); // Just some sugar to detect the component

What’s benefit from this approach?

This is based on a concept of attaching / detaching entities or components from the world, so they are being created but not being added to any query.
But this is already outdated as we were thinking about other ways to provide that functionality that will get added soon to the repo. Closing it
