I started this project making an really smooth controlled pickup system,
I achieved this by adding damping, jiggle effect, rotation and throwing.
Together it looks like this:
using Cinemachine;

[Header("Throw Settings")]
[SerializeField] private float timer = 1;

{

}
void Update()
{

heldObject.GetComponent<Rigidbody>().AddForce(-transform.up * heldObject.GetComponent<Rigidbody>().mass * 35);
}

Besides the pickup system I created Puzzles/MiniGames designed by the artists, for the player to solve also using the pickup and throwing mechanic.
I created scripts for the buttons used in the minigames to connect to that minigame.
public class PlateDown : MonoBehaviour
{
private Vector3 upPos;
private Vector3 downPos;
public bool On = false;
void Start()
{
upPos = transform.position;
downPos = transform.position -= new Vector3(0, 0.1f, 0);
}
void Update()
{
if (On)
transform.position = Vector3.Lerp(transform.position, downPos, 1 * Time.deltaTime);
else if (On == false)
transform.position = Vector3.Lerp(transform.position, upPos, 1 * Time.deltaTime);
}

else
Plate.transform.position = Vector3.MoveTowards(Plate.transform.position, BackPos.position, 1 * Time.deltaTime);
}
private void OnTriggerStay(Collider other)
{
ReliableOnTriggerExit.NotifyTriggerEnter(other, gameObject, OnTriggerExit);
if (other.gameObject.CompareTag("Player") || other.gameObject.CompareTag("Clone") || other.gameObject.CompareTag("CubeNormal"))
On = true;
}
private void OnTriggerExit(Collider other)
{
ReliableOnTriggerExit.NotifyTriggerExit(other, gameObject);
if (other.gameObject.CompareTag("Player") || other.gameObject.CompareTag("Clone") || other.gameObject.CompareTag("CubeNormal"))

For easier gameplay I created the checkpoint system.
By entering a level you enter a collider that lets you respawn at the beginning of the level also resetting every object in the level.
Also added a fade-in so it's smoother
public class CheckPointManager : MonoBehaviour
{
public CheckPointItems[] CheckPoints;
public Transform spawnPoint;
[SerializeField] private CharacterController characterCont;
private UnityEngine.CharacterController characterController;
[SerializeField] private PlayerLook playerL;
[SerializeField] private GameObject player;
[SerializeField] private Animator fade;
[SerializeField] private Transform cam;
[SerializeField] private Transform oldCam;
[SerializeField] private DialogueSystem dialogue;
private bool kill = false;
private void Start()
{
cam.transform.localRotation = Quaternion.Euler(90, transform.localRotation.y, transform.localRotation.z);
characterController = FindObjectOfType<UnityEngine.CharacterController>();
}
private void Update()
{
if (kill)
cam.position = Vector3.Lerp(cam.position, new Vector3(cam.position.x, cam.position.y + 5, cam.position.z), 0.3f * Time.deltaTime);
if (Input.GetKeyDown(KeyCode.L))
{
Respawn();
}
}
public void Respawn()
{
StartCoroutine(RespawnAtCheckPoint(oldCam));
}
public void AddCheckPoint(Transform _checkPointPos)
{
spawnPoint = _checkPointPos;
}
private IEnumerator RespawnAtCheckPoint(Transform _OldPos)
{
kill = true;
playerL.enabled = false;
cam.transform.localRotation = Quaternion.Euler(0, transform.localRotation.y, transform.localRotation.z);
dialogue.PlayRandomDialogue();
characterCont.enabled = false;
characterController.enabled = false;
fade.Play("Eyes");
yield return new WaitForSeconds(2);
kill = false;
cam.transform.localRotation = Quaternion.Euler(0, 0, 0);
player.transform.position = spawnPoint.position;
cam.position = _OldPos.position;
ResetRoom();
yield return new WaitForSeconds(1);
playerL.enabled = true;
characterCont.enabled = true;
characterController.enabled = true;
}
private void ResetRoom()
{
FindObjectOfType<Controller>().DestroyClone();
int _roomCode = -1;
for (int i = 0; i < CheckPoints.Length; i++)
{
if (spawnPoint == CheckPoints[i].CheckPoint.spawnPos)
_roomCode = i;
}
if (CheckPoints[_roomCode].ObjectsToReset.Length > 0 && _roomCode >= 0)
{
foreach (GameObject roomItem in CheckPoints[_roomCode].ObjectsToReset)
{
if (roomItem.TryGetComponent(out ObjectRespawn objectRespawn))
{
objectRespawn.ResetObject();
}
else if (roomItem.GetComponentInChildren<PlateDown>())
{
roomItem.GetComponentInChildren<PlateDown>().On = false;
}
}
}
}
}
[System.Serializable]
public class CheckPointItems
{
public CheckPoint CheckPoint;
public GameObject[] ObjectsToReset;
}
public class Kill : MonoBehaviour
{
private CheckPointManager checkPointManager;
private Controller cont;
void Start()
{
cont = FindObjectOfType<Controller>();
checkPointManager = FindObjectOfType();
}
private void OnTriggerEnter(Collider other)
{
if (other.gameObject.CompareTag("Player"))
checkPointManager.Respawn();
if (other.gameObject.CompareTag("Clone"))
cont.DestroyClone();
}
}
As extra I created a transition between levels using an elevator
using Cinemachine;
public class Elevator : MonoBehaviour
{
public GameObject Player;
public Transform ElevatorPos;
private UnityEngine.CharacterController characterCont;
private Animator elevatorAnim;
CinemachineVirtualCamera vCam;
private void Start()
{
vCam = FindObjectOfType<PlayerRecorder>().gameObject.GetComponentInChildren<CinemachineVirtualCamera>();
characterCont = FindObjectOfType<UnityEngine.CharacterController>();
elevatorAnim = GetComponentInChildren<Animator>();
}
public IEnumerator ElevatorChange()
{
AudioManager.instance.Play("ElevatorOpen");
elevatorAnim.Play("ElevatorClose");
yield return new WaitForSeconds(2);
AudioManager.instance.Play("ElevatorMusic");
vCam.GetCinemachineComponent<CinemachineBasicMultiChannelPerlin>().m_FrequencyGain = 8;
characterCont.enabled = false;
Player.transform.SetParent(this.transform);
yield return new WaitForSeconds(0.01f);
if (ElevatorPos != null)
{
transform.position = ElevatorPos.position;
transform.rotation = ElevatorPos.rotation;
}
yield return new WaitForSeconds(0.01f);
Player.transform.SetParent(null);
characterCont.enabled = true;
yield return new WaitForSeconds(10);
vCam.GetCinemachineComponent<CinemachineBasicMultiChannelPerlin>().m_FrequencyGain = 1;
yield return new WaitForSeconds(1);
AudioManager.instance.Play("ElevatorEnd");
elevatorAnim.Play("ElevatorOpen");
}
}
And ofcourse I added cutscenes to the game for getting more feeling into it.
And The last thing I worked on is the main menu. Having a background music, working button and a moving background
In project Short Burn, me and a small group tried to achieve the highest possible quality in an indie First Person Puzzler. Our core mechanic is to record your movement(Movement, Rotation) and spawn a clone that does that exact movement.
we made this game with the following game design patterns:
Flow, Pacing, Cells, Portals, Pick ups, Lay-out
