# Your first verifiable prototype

id: first-prototype
type: path
key: path/first-prototype
lang: en
status: active
url: https://gamemechanics.pro/en/learn/first-prototype/

One scene: from a question and input to feedback, measurement and reviewing agent work.

## Before you start

No existing project is required.

## Lesson sequence

1. [Scope and a testable prototype](https://gamemechanics.pro/en/lessons/scope-and-prototype/)
2. [The game loop and time](https://gamemechanics.pro/en/lessons/game-loop/)
3. [Input and feedback](https://gamemechanics.pro/en/lessons/input-and-feedback/)
4. [Collision fundamentals](https://gamemechanics.pro/en/lessons/collision-basics/)
5. [States and transitions](https://gamemechanics.pro/en/lessons/state-machines/)
6. [Game feel: making actions readable](https://gamemechanics.pro/en/lessons/game-feel/)
7. [A performance budget](https://gamemechanics.pro/en/lessons/performance-budget/)
8. [Developing a game with an AI agent](https://gamemechanics.pro/en/lessons/agent-workflow/)
9. [Verifying gameplay behavior](https://gamemechanics.pro/en/lessons/gameplay-acceptance/)

## Put it into practice

Start with a paper test of the idea. Then use the lesson tasks to build one scene and check it against the conditions above.

- [A current on paper](https://gamemechanics.pro/en/practice/#paper-current)
- [Rhythm without rushing](https://gamemechanics.pro/en/practice/#rhythm-without-hurry)

## Outcome

One playable scene with a single action, quick restart and a reproducible check.

## Completion checks

- The prototype answers a recorded question and has a stopping criterion.
- The action, pause, restart and feedback are checked in the target environment.
- Agent changes are explained and supported by observable results.
