Giving the Limited Grant #

There are several circumstances where players might be granted a one-time reward:

  • New player bonus
  • Returning player incentives
  • Seasonal or event reward (such as logging in at least once during an event)

For demonstration purposes, we’ll be manually simulating service calls with Postman. This guide currently covers a basic reward scenario where the player is granted items shortly after logging in.


Start Pragma Engine #

Run make run to start Pragma Engine. Run this in a terminal with platform as the working directory.

  • Alternatively, Pragma Engine can be run from IntelliJ. From the IntelliJ toolbar in the upper right, ensure MainKt - LocalConfigured is selected, then click the play button.
  • If not, click Add Configuration…. In the Run/Debug Configurations window that appears, expand Kotlin in the left hand side, then select MainKt - LocalConfigured. Click OK. Click the play button in the IntelliJ toolbar to start Pragma Engine.
  • Once the engine has started successfully, it prints the message [main] INFO main - Pragma server startup complete.

Grant the reward #

  1. Log in using Postman by sending PragmaDev ➨ Social ➨ Player ➨ Account ➨ authenticateOrCreateV2.
  2. Send PragmaDev ➨ Game ➨ RPC - Player ➨ Inventory ➨ getInventoryV2 to confirm that the player has an empty inventory.
  3. Send PragmaDev ➨ Game ➨ RPC - Player ➨ GameData ➨ getLoginDataV1 to perform the limited grant. The items granted can be seen in the body of the response.
  4. Resend PragmaDev ➨ Game ➨ RPC - Player ➨ Inventory ➨ getInventoryV2 and confirm that the player was granted a laserSword and 50 coins. Also note the presence of a StarterPack, which is used to prevent the player from receiving more limited grants than they are entitled to.
  5. Resend PragmaDev ➨ Game ➨ RPC - Player ➨ GameData ➨ getLoginDataV1 then resend PragmaDev ➨ Game ➨ RPC - Player ➨ Inventory ➨ getInventoryV2. Confirm that the player did not receive an additional laserSword or any additional coins.
