This module aims to provide a very generic framework to simulate an economy with consumers and producers. On top of that however, it provides a robust method to share/trade/exchange resources between entities. It does so under a very libertarian credo: Use any storage component you want.

To see how you can get started with it and how you can hook it into your module see the wiki!

This module can provide an alternative Inventory Screen that displays an in-game shop with purchasable items in addition to the regular player inventory. Whether this alternative screen is shown depends on the presence (or absence) of the AllowShopScreenComponent on a client entity.

By default, clients cannot see the alternative shop screen.

To enable it, add an event handler to ensure that joining clients will have the AllowShopScreenComponent attached to their entity. You may use the following code snippet and add it to a registered system.

/**
 * Ensure that the client has the {@link AllowShopScreenComponent} such that they can use the in-game shop from the Economy module.
 * @param event connection event when a client (and their player) joins a game/server
 * @param entity the client entity
 */
@ReceiveEvent
public void onConnect(ConnectedEvent event, EntityRef entity) {
    entity.upsertComponent(AllowShopScreenComponent.class, c -> c.orElse(new AllowShopScreenComponent()));
}
