Overview

Team project rebuilding a Cuphead-style level. Artists produced hand-drawn assets and programmers implemented core mechanics. My primary contribution was implementing moving-platform behaviour: platforms detect when the player stands on them, move down, wait, then return smoothly while maintaining correct collision and player attachment.

Features

• Boss AI that blends phase-based patterns with small reactive behaviours.
• Precise movement and shooting tuned around frame-by-frame capture.
• Config-driven attack patterns that designers can tweak without touching code.
• Lightweight debug overlay for hitboxes, timings and iframes.

My contribution

• Designed and implemented the full gameplay loop, from movement to boss logic.
• Built a modular state machine system for boss behaviour and transitions.
• Created tooling to quickly iterate on attack timings and difficulty.
• Profiled and optimised update loops to keep the prototype responsive.

Code snippets

Moving platform (player-triggered)

public class MovingPlatform : MonoBehaviour
{
    [SerializeField] private Vector3 downOffset = new Vector3(0, -1f, 0);
    [SerializeField] private float downDuration = 0.25f;
    [SerializeField] private float upDuration = 0.4f;
    [SerializeField] private float waitTime = 0.6f;

    private Vector3 _startPos;
    private Coroutine _moveRoutine;

    void Awake() => _startPos = transform.localPosition;

    void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.collider.CompareTag("Player") && _moveRoutine == null)
            _moveRoutine = StartCoroutine(PlatformRoutine(collision.collider));
    }

    private IEnumerator PlatformRoutine(Collider2D player)
    {
        var target = _startPos + downOffset;
        yield return StartCoroutine(LerpPosition(transform, _startPos, target, downDuration));

        // Keep player attached while platform is moving
        player.transform.SetParent(transform);
        yield return new WaitForSeconds(waitTime);

        yield return StartCoroutine(LerpPosition(transform, target, _startPos, upDuration));

        // Detach player
        player.transform.SetParent(null);
        _moveRoutine = null;
    }

    private IEnumerator LerpPosition(Transform t, Vector3 a, Vector3 b, float duration)
    {
        float elapsed = 0f;
        while (elapsed < duration)
        {
            t.localPosition = Vector3.Lerp(a, b, elapsed / duration);
            elapsed += Time.deltaTime;
            yield return null;
        }
        t.localPosition = b;
    }
}
