Indie Game Jam: John was sleeping

I took part to the game jam in late 2021.

Game mechanics that I implemented:

  • Movement(Driving, Walking)
  • Camera rotation
  • Bomb diffusion
    • Select button/cable
    • Click button/cable
    • Hold input in memory/ check input if correct

Each bomb object has a script attached to it that holds user’s input and checks if input is correct. If input is not correct or timer reaches zero bomb explodes.

public class Bomb : MonoBehaviour
{

    public float delay = 50f;
    public float radius = 5f;
    public float force = 700f;

    public GameObject explosionEffect;

    public bool hasExploded;

    public MeshDestroy meshDestroyObject;

    public AudioSource audioSource1;
    public AudioSource audioSource2;

    // Update is called once per frame
    void Update()
    {
       
        if(hasExploded){
            meshDestroyObject.explode = true;
            Explode();
        }
    }

    void Explode(){
        // We instantiate the explosion where this bomb object is!
        Instantiate(explosionEffect, transform.position, transform.rotation);
        audioSource1.Play();
        audioSource2.Play();

    }
}

Bomb types and input check system:

  • Bomb with keypad
    • Press buttons in correct order to diffuse bomb
    • When a button is pressed I append the number depicted on the button to a string. When the string length == 4, an equal check is done between that string and another with the correct password. If they are not equal bomb explodes.
public class ClockBomb_NumPad : MonoBehaviour
{
    public bool isEnabled;

    public Bomb bomb;
    float countdown;
    public Transform time_text;
    public Transform pass_text;

    public string _password;
    string passwordInserted;

    public void initBomb(){
        countdown = bomb.delay;
        passwordInserted = "";
        isEnabled = true;
    }

    void Update(){
        if(isEnabled){
            if (countdown > 0)
                countdown -= Time.deltaTime;
            else{
                boom();
            }
            time_text.GetComponent<TextMesh>().text = countdown.ToString("F2");
        }
    }

    public AudioSource diffused;
    public void checkPassword(){
        if(passwordInserted == _password){
            //"You diffused the bomb!"
            isEnabled = false;
            diffused.Play();
        }else{
            boom();
        }
    }

    public void buttonPressed(int number){
        if(passwordInserted.Length <= 3){
            passwordInserted += number.ToString();
            pass_text.GetComponent<TextMesh>().text = passwordInserted;
            if(passwordInserted.Length == 4)
                checkPassword();
        }
    }

    void boom(){
        //"Boom!!"
        bomb.hasExploded=true;
        isEnabled = false;
        Destroy(gameObject);
    }
}
  • Bomb with cables(Cut the right color)
    • When a cable is clicked it gets cut. If cable is the color needed, bomb is unarmed. If wrong color clicked or timer runs up it explodes.
  • Bomb with cables(Cut them in the right order)
    • When a cable is clicked it gets cut. There is a list in memory that holds the correct cable’s id to be cut. If the order is wrong or timer runs up bomb explodes.
public class ClockBomb_InOrder : MonoBehaviour
{
    public bool isEnabled;
    public Bomb bomb;
    float countdown;
    public Transform text;
    int cables_num;
    int _indexList;
    public List<int> cablesToCutOrder;
    public void initBomb(){
        cables_num = 4;
        countdown = bomb.delay;
        isEnabled = true;
    }

    void Update(){
        
        if(isEnabled){
            if (countdown > 0)
                countdown -= Time.deltaTime;
            else{
                boom();
            }
            text.GetComponent<TextMesh>().text = countdown.ToString("F2");
        }
    }

    public AudioSource diffused;
    public void cutCable(int index){
        if(cablesToCutOrder[_indexList++] != index){
            boom();
        }else{
            if(_indexList == cables_num){
                //You diffused the bomb!
                isEnabled = false;
                diffused.Play();
            }
        }
    }

    void boom(){
        //Boom!!
        bomb.hasExploded=true;
        isEnabled = false;
        Destroy(gameObject);
    }


    void initList(){
        int cable_no;
        bool found;
        for(int i = 0; i < cables_num; i++){
            do{
                found = false;
                cable_no = Random.Range(0,cables_num);
                for(int j = 0; j < i; j++){
                    if(cablesToCutOrder[j] == cable_no){
                        found = true;
                        break;
                    }
                }
            } while(found == true);
            cablesToCutOrder[i] = cable_no;
        }
    }
}
