Elemental tower defense

Overview

Elemental Tower Defense is my first tower defense game, where you need to defend your base against skeleton enemies with your elemental towers. Such as a fire tower that fires rapidly or an ice tower that slows the enemy down.

Reflection

This was my first tower defense project that I created at school with help from classmates and AI. I struggled most with starting scripts and structuring my code properly. It was also difficult to make my game good replayability wise.

What I Used

Features

• Wave system
• Music
• Different towers
• Tower sell mechanic

Development Sheet

void Update()
{
    if (isPlacingTower)
    {
        FollowMouseWithTower();

        if (Input.GetMouseButtonDown(0))
        {
            Tower tower = currentTower.GetComponent();
            tower.isPlaced = true;

            PlaceTower();
        }
    }
}

Tower placement

With left mouse button you can place towers around the map up to 7 towers.

tower follows mouse until placed
Limit of 7 towers
Can place everywhere

public void SellTower()
private void SellTowers()
{
    foreach (Transform t in towerList)
    {
        currency.AddMoney(50);
        Destroy(t.gameObject); 
    }
    towerList.Clear();
    placement.towerAmount = 0; 
}

Tower sell

The towers sell mechanic lets players sell all their towers at once for currency

Sells all towers at once
Low currency return
strategic button to use

    void Start()
    {
        m_CurrencyText.text = "$: " + Money.ToString();
    }

    void Update()
    {
        
    }

    public void AddMoney(int money)
    {
        Money += money;
        m_CurrencyText.text = "$: " + Money.ToString();

    }

    public void RemoveMoney(int money) 
    {
        Money -= money;
        m_CurrencyText.text = "$: " + Money.ToString();
}

Currency System

The currency system lets players earn money by killing enemies to buy new towers.

can buy different towers
50$ with each kill
Improves replayability
