Skill Tree

Open in a new tab

Overview

Recruit a character, open its skill tree, and spend coins to unlock nodes. The tree has four nodes, first, left, right and last: left and right each require first, and last requires both left and right. Progress is kept separately for each character, and an unlocked node can be put back for half of what it cost.

How to try it

  1. Press Recruit under Recruit a character. A row for the character appears under Open a character’s tree.
  2. Press Deposit under Get coins to put 100 free coins into Your coins. The four nodes cost 10, 20, 20 and 50, exactly 100 in total.
  3. Press Open tree on the character’s row. The Skill tree opens, showing each node’s name, its cost, and what pressing it would do.
  4. Press Release on first to pay 10 coins and unlock it. Pressing Release on a node whose prerequisites are still locked unlocks those prerequisites in the same press, as the node’s line says (releases 2, 30 total on left).
  5. Press Restrain on an unlocked node to lock it again, along with any unlocked nodes that depend on it; 50% of the cost comes back as coins.
  6. Press Close, recruit another character and open its tree to see that each character keeps its own progress.

GS2 services used

  • GS2-SkillTree: GS2-SkillTree node models define the four nodes, their prerequisites, the coins each charges on release, and the return rate of 0.5 when one is put back. Progress is recorded per recruited character, keyed by its item set (propertyId).
  • GS2-Money2: A GS2-Money2 wallet holds the coins. Releasing a node withdraws its cost through Gs2Money2:WithdrawByUserId.
  • GS2-Inventory: GS2-Inventory holds the recruited characters; each character’s item set GRN is the key that says whose skill tree is being read.
  • GS2-Exchange: GS2-Exchange rate models define Recruit, which grants a character, and Deposit, which pays in free coins.
