Gacha Video Game APIs: Separate Animation from Rewards
Design durable round IDs, replay handling, inventory updates, and transparent outcomes without trusting a client-side animation.
THE ARM LAB / CATEGORY: GAME DEVELOPMENT
Design virtual claws, repeatable rounds, and a clean separation between visual reveals and authoritative outcomes.
A convincing claw animation is only one part of a game interaction. Input handling, round progression, capture rules, and result presentation need their own contracts. This collection treats the visible cabinet as a renderer of state rather than a source of unexplained rewards.
Start with the virtual claw loop guide to understand aiming, descending, returning, cancellation, and reset. Continue to the reward-state article when a project introduces persistent outcomes or a separate authority. The distinction matters even when the animation looks identical.
The practice cabinet is intentionally local and deterministic. It does not charge money, award items, connect to a physical claw, or store inventory. The gacha game arm overview documents its exact hit regions, while the video game integration overview explains how to keep rendering independent from result authority. Use the examples to learn lifecycle boundaries, not as an undisclosed substitute for commercial game infrastructure.
Design durable round IDs, replay handling, inventory updates, and transparent outcomes without trusting a client-side animation.
Model aim, descend, close, and return as explicit states. Keep virtual mechanics understandable and independent of frame rate.
A little code. A lot to explore.
