An Ability System Component coordinates a gameplay ability, gameplay effect and attribute set. A synthetic attack applies a damage effect that changes health from 100 to 80. — Conceptual GAS relationships. The attack, damage amount and health values are synthetic examples.

Use it for: Combat abilities, buffs and stats coordinated with animation and effects.

Start: 1) Read the overview and Ability System Component. 2) Define a health attribute and a modifying effect. 3) Build one attack ability before adding complex rules.

A request passes through activation checks. Failure leads to Blocked; success leads to Active, which can Complete or be Cancelled. — A conceptual test map for ability activation and termination; actual checks and effects depend on the project.

Try checking: Trace what starts the ability and changes attributes; include blocked and cancelled activation cases.

Limits: GAS is a framework, not a complete combat kit. Your project supplies its gameplay rules and integration. Match documentation to your engine version.
