Invitations

Overview​

With the help of invites, you can manage the addition of players to the channel. Since you can implement chats, guilds, lobbies and much more on the basis of channels, invites become an integral part of them and provide the mechanism for joining somewhere. For example, a player may be asked to join a:

  • group or team
  • raid
  • guild or clan
  • community and so on

The mechanics of invites 💡 may be as follows: when a player is going to be invited somewhere, a flashing icon appears in the center of the screen with a proposal to join a chat, group, or raid and basic information about this event. In this case, the player can accept the offer, refuse, ignore, etc.

tip

The mechanics of invites 💡 is given as an example. The GamePush service does not visually display anything, but the developer can implement it on his own
