Create enemy with multiple waves/attacks?

Question

Hello, I'm creating a 2D sidescroller and I'm extremely new to Unity. I'm wondering how I could make a large boss battle enemy, where it's a giant ear of corn that has multiple waves for attacks, each getting progressively more difficult as they go. I was wondering how I'd be able to pull that off? I'm very new to coding as a whole so please keep the answers simple and easy to understand, thanks!

If I am going to be honest it is a bit complex. First off you need some sort of health system to give both you and the boss health. The boss's max health should be much higher than the players obviously. Maybe you can have it so the corn loses some of its peaces each wave. So say there is 4 waves which I think is perfect for a boss. The first wave have some simple basic enemies that will give you items to help you face the boss's next wave. The second wave you should have an attack that does an increased amount of damage than any of his attacks so far. If you are left surviving then you once again get the same wave of simple mobs. The next two waves should be hard work. Make the mobs much harder and the final attack all of his kernels popping off. Now his angry and much faster but is also much weaker. So first off. Start with the simplest thing which is a script for health.

Here is an example:

 //The max health of the creature 
     //you are adding the script to.
     public int maxHealth = 100;
 
     //The health the creature currently has.
     private int currentHealth;
     void Start () {
         //On start set it's health to full health.
         currentHealth = maxHealth;
     }
 
     void TakeHealth(int DamageAmount)
     {
         //If you want this to do damage then 
         //set the damage value as a negative number.
         currentHealth += DamageAmount;
     }

Next you are going to need some sort of system of attacking. That is all up to your imagination. If you would like more help feel free to comment on my answer :D.

Thanks for replying, now do I need to make this a whole new script, or should I add it to my "Player" script? $$anonymous$$eep in mind that I'm using C#.

Ya you probably want to have a couple scripts here. Obviously theres a bunch of different ways to do it but something like this might work.

Player (handles movement and attacks for player)
Boss (handles attacks and phases for boss)
Enemy script (handles movement and attacks for enemy
Health (manages health and maybe its display to UI as well, referenced by player, boss, enemy)
Projectile (handles projectile movement and damaging things when collided with)
Wave$$anonymous$$anager (communicates with boss and spawns waves of enemies at correct times)

Is there a way that you could help me with this? I just now added the Health code, how would I make it so my player has health, and the enemy sprite has health as well. I also have no weapons or any way for the player to "hurt" the enemy sprite. I want to add a health bar GUI for both the player and enemy sprite. The player sprite will wield a sword-like weapon.

How does your player script look? Then we can decide.

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

public class Player : $$anonymous$$onoBehaviour { public float maxSpeed = 3; public float speed = 50f; public float jumpPower = 150f; public float jumpSpeed = 8f; private Rigidbody2D rigidBody;

 public bool grounded;

 private Rigidbody2D rb2d;
 private Animator anim;

 void Start ()

     rb2d = gameObject.GetComponent<Rigidbody2D> ();

     {
         anim.SetBool ("Grounded", grounded);
         anim.SetFloat ("Speed", $$anonymous$$athf.Abs (Input.GetAxis ("Horizontal")));

         if (Input.GetAxis ("Horizontal") < -0.1f)
             transform.localScale = new Vector3 (-1, 1, 1);

         if (Input.GetAxis ("Horizontal") > 0.1f)
             transform.localScale = new Vector3 (1, 1, 1);


         if (Input.Get$$anonymous$$eyDown ($$anonymous$$eyCode.Space) && grounded) {

 void FixedUpdate ()
 {
     {

         float h = Input.GetAxis ("Horizontal");
         //$$anonymous$$oving the player
         rb2d.AddForce ((Vector2.right * speed) * h);

         //Limiting the speed of player
         if (rb2d.velocity.x > maxSpeed) {
             rb2d.velocity = new Vector2 (maxSpeed, rb2d.velocity.y);
         }

         if (rb2d.velocity.x < -maxSpeed) {
             rb2d.velocity = new Vector2 (-maxSpeed, rb2d.velocity.y);
         }
     }
 }

There is two ways. You can do it using Unity’s OnGui() function or you can manually create a Canvas with a ui health slider. Tell me which you would rather use

I'd much rather create a canvas, as this makes it more customizable, right?

@Digitroni

Ok then make a canvas and create a slider under ui. Then all you have to do is set the sliders value to whatever the health is.

Okay, I created a canvas, am I supposed to pair it to the $$anonymous$$ainCamera? And I also added the slider UI, and now theres just a random slider floating above my player in game.

Well you will want to do:

 //Include this with your health class
 using UnityEngine.UI;
 
 //Add this to your variables
 public Slider healthSlider;
 
 void Start() {
     //Put this in to your void Start()
     healthSlider.value = health;
 }
 
 //Put it in to your //TakeDamage $$anonymous$$ethod
  void TakeDamage(int DamageAmount) {
     healthSlider.value = health;
 }
