Hi everyone 
I’m creating an online game and currently in the process of making a “Loading popup” to block the player’s input while waiting for network operations to complete.
For example, when a player opens their inventory, the client sends a message to the server to retrieve the item data, and the client displays a loading popup while waiting for the server’s response. Once the response is received, the popup closes.
The issue I’m facing is how to handle multiple actions, such as “login, loading other player’s information, interacting with NPCs…” in a flexible way.
Thank you
