Skill Tree

A skill tree is a collection of skill nodes that can be unlocked by skill points the player gets each level.

Built-in Skill Trees

• vampirism:vampire/level
• vampirism:vampire/lord
• vampirism:hunter/level
• vampirism:hunter/lord

The both level skill trees are unlocked by joining the faction, while both lord skill trees are unlocked by reaching the first lord level of the faction.

Creating a skill tree

A skill tree has the following structure:

data/<modid>/vampirism/skill_trees/<skill-tree-path>.json

{
  "display": <item-stack>,
  "faction": {
    "id": "<faction-id>"
  },
  "name": <Component>,
  "unlock_predicate": <entity-predicate>,
}

Field	Type	Description
display	itemstack	The item stack that is used to display the skill tree in the GUI.
faction	ResourceLocation	The faction the skill tree belongs to.
name	Component	The display name of the skill tree.
unlock_predicate	entity-predicate	The predicate that is used to determine if the skill tree is unlocked.

Example

data/vampirism/vampirism/skill_trees/vampire/lord.json

{
  "display": {
    "Count": 1,
    "id": "vampirism:vampire_minion_binding"
  },
  "faction": {
    "id": "vampirism:vampire"
  },
  "name": {
    "translate": "text.vampirism.skills.lord"
  },
  "unlock_predicate": {
    "type_specific": {
      "type": "vampirism:faction",
      "faction": {
        "id": "vampirism:vampire"
      },
      "lord_level": 1
    }
  }
}

The vampire lord skill tree is unlocked when the player has the vampire faction and a minimum lord level of 1. With the Vampire Minion Binding as item and the translation of text.vampirism.skills.lord as name.
