Implementation Patterns
Stat Growth Formula
Core implementation pattern for handling karma system logic with clean state management.
const progressionTree = {
nodes: [
{ id: "novice_skill", cost: 1, requires: [], effect: "+10% damage" },
{ id: "improved_skill", cost: 3, requires: ["novice_skill"], effect: "+25% damage, unlock combo" },
{ id: "master_strike", cost: 5, requires: ["improved_skill"], effect: "+50% damage, unlock ultimate" },
],
canUnlock(nodeId: string, points: number, unlocked: Set<string>) {
const node = this.nodes.find(n => n.id === nodeId);
if (!node || unlocked.has(nodeId)) return false;
return points >= node.cost
&& node.requires.every(r => unlocked.has(r));
}
};
