Hi, how do you fast forward the time while checking the sprouting? Also, thank you so much for this tutorial.

I’m facing another problem: I’m not able to plant seeds smoothly. I have to keep clicking on the inventory bag repeatedly to either plant, water, or use any other tool. This makes the process very inefficient.

I downloaded the zip file, and I’m using Unity version 2019.4.41f2. Can you help me fix this issue?

Following code is for land:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Land : MonoBehaviour, ITimeTracker
{
    public enum LandStatus
    {
        Soil, Farmland, Watered
    }

    public LandStatus landStatus;

    public Material soilMat, farmlandMat, wateredMat;
    new Renderer renderer;

    //The selection gameobject to enable when the player is selecting the land
    public GameObject select;

    //Cache the time the land was watered 
    GameTimestamp timeWatered;

    [Header("Crops")]
    //The crop prefab to instantiate
    public GameObject cropPrefab;

    //The crop currently planted on the land
    CropBehaviour cropPlanted = null;

    // Start is called before the first frame update
    void Start()
    {
        //Get the renderer component
        renderer = GetComponent<Renderer>();

        //Set the land to soil by default
        SwitchLandStatus(LandStatus.Soil);

        //Deselect the land by default
        Select(false);

        //Add this to TimeManager's Listener list
        TimeManager.Instance.RegisterTracker(this);
    }

    public void SwitchLandStatus(LandStatus statusToSwitch)
    {
        //Set land status accordingly
        landStatus = statusToSwitch;

        Material materialToSwitch = soilMat; 

        //Decide what material to switch to
        switch (statusToSwitch)
        {
            case LandStatus.Soil:
                //Switch to the soil material
                materialToSwitch = soilMat;
                break;
            case LandStatus.Farmland:
                //Switch to farmland material 
                materialToSwitch = farmlandMat;
                break;

            case LandStatus.Watered:
                //Switch to watered material
                materialToSwitch = wateredMat;

                //Cache the time it was watered
                timeWatered = TimeManager.Instance.GetGameTimestamp(); 
                break; 

        }

        //Get the renderer to apply the changes
        renderer.material = materialToSwitch; 
    }

    public void Select(bool toggle)
    {
        select.SetActive(toggle);
    }

    //When the player presses the interact button while selecting this land
    public void Interact()
    {
        //Check the player's tool slot
        ItemData toolSlot = InventoryManager.Instance.equippedTool;

        //If there's nothing equipped, return
        if (toolSlot == null)
        {
            return; 
        }

        //Try casting the itemdata in the toolslot as EquipmentData
        EquipmentData equipmentTool = toolSlot as EquipmentData; 

        //Check if it is of type EquipmentData 
        if(equipmentTool != null)
        {
            //Get the tool type
            EquipmentData.ToolType toolType = equipmentTool.toolType;

            switch (toolType)
            {
                case EquipmentData.ToolType.Hoe:
                    SwitchLandStatus(LandStatus.Farmland);
                    break;
                case EquipmentData.ToolType.WateringCan:
                    SwitchLandStatus(LandStatus.Watered);
                    break;
            }

            //We don't need to check for seeds if we have already confirmed the tool to be an equipment
            return; 
        }

        //Try casting the itemdata in the toolslot as SeedData
        SeedData seedTool = toolSlot as SeedData; 

        ///Conditions for the player to be able to plant a seed
        ///1: He is holding a tool of type SeedData
        ///2: The Land State must be either watered or farmland
        ///3. There isn't already a crop that has been planted
        if(seedTool != null && landStatus != LandStatus.Soil && cropPlanted == null)
        {
            //Instantiate the crop object parented to the land
            GameObject cropObject = Instantiate(cropPrefab, transform);
            //Move the crop object to the top of the land gameobject
            cropObject.transform.position = new Vector3(transform.position.x, 0, transform.position.z);

            //Access the CropBehaviour of the crop we're going to plant
            cropPlanted = cropObject.GetComponent<CropBehaviour>();
            //Plant it with the seed's information
            cropPlanted.Plant(seedTool);

        }
    }

    public void ClockUpdate(GameTimestamp timestamp)
    {
        //Checked if 24 hours has passed since last watered
        if(landStatus == LandStatus.Watered)
        {
            //Hours since the land was watered
            int hoursElapsed = GameTimestamp.CompareTimestamps(timeWatered, timestamp);
            Debug.Log(hoursElapsed + " hours since this was watered");

            //Grow the planted crop, if any
            if(cropPlanted != null)
            {
                cropPlanted.Grow();
            }

            if(hoursElapsed > 24)
            {
                //Dry up (Switch back to farmland)
                SwitchLandStatus(LandStatus.Farmland);
            }
        }
    }
}

Following code is for CROP BEHAVIOUR:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CropBehaviour : MonoBehaviour
{
    //Information on what the crop will grow into 
    SeedData seedToGrow;

    [Header("Stages of Life")]
    public GameObject seed;
    private GameObject seedling;
    private GameObject harvestable;

    //The growth points of the crop
    int growth;
    //How many growth points it takes before it becomes harvestable
    int maxGrowth; 

    public enum CropState
    {
        Seed, Seedling, Harvestable
    }
    //The current stage in the crop's growth
    public CropState cropState;

    //Initialisation for the crop GameObject
    //Called when the player plants a seed
    public void Plant(SeedData seedToGrow)
    {
        //Save the seed information
        this.seedToGrow = seedToGrow;

        //Instantiate the seedling and harvestable GameObjects
        seedling = Instantiate(seedToGrow.seedling, transform);

        //Access the crop item data
        ItemData cropToYield = seedToGrow.cropToYield;

        //Instantiate the harvestable crop
        harvestable = Instantiate(cropToYield.gameModel, transform);

        //Convert Days To Grow into hours
        int hoursToGrow = GameTimestamp.DaysToHours(seedToGrow.daysToGrow);
        //Convert it to minutes
        maxGrowth = GameTimestamp.HoursToMinutes(hoursToGrow); 

        //Set the initial state to Seed
        SwitchState(CropState.Seed); 

    }

    //The crop will grow when watered
    public void Grow()
    {
        //Increase the growth point by 1
        growth++;

        //The seed will sprout into a seedling when the growth is at 50%
        if(growth >= maxGrowth / 2 && cropState == CropState.Seed)
        {
            SwitchState(CropState.Seedling); 
        }

        //Grow from seedling to harvestable
        if(growth >= maxGrowth && cropState == CropState.Seedling)
        {
            SwitchState(CropState.Harvestable);
        }
    }

    //Function to handle the state changes 
    void SwitchState(CropState stateToSwitch)
    {
        //Reset everything and set all GameObjects to inactive
        seed.SetActive(false);
        seedling.SetActive(false);
        harvestable.SetActive(false);

        switch (stateToSwitch)
        {
            case CropState.Seed:
                //Enable the Seed GameObject
                seed.SetActive(true);
                break;
            case CropState.Seedling:
                //Enable the Seedling GameObject
                seedling.SetActive(true);
                break;
            case CropState.Harvestable:
                //Enable the Harvestable GameObject
                harvestable.SetActive(true);
                //Unparent it to the crop
                harvestable.transform.parent = null;

                Destroy(gameObject); 
                break;
        }

        //Set the current crop state to the state we're switching to
        cropState = stateToSwitch; 
    }
}

Hi, you hold down the right square bracker (“]”) to fast forward the time.

In regards to the inventory design, just continue to follow the series, the improvements to the inventory system will be made.
