Hey follow me on Discord. Link is here discord.gg/78q3HFnb69 You can ask for help , post what your working on and get motivated , show your funny bugs and memes and more.
Awesome video, it helped me alot with making the enemy move, the one thing that would be cool is if someone could tell me how to restrict the enemy movement to the x axis so I can use it for my 2D platformer
you wouldnt use .MoveTowards you would have a vector to represent its current position and then += a vector 2 where you can make either x or y 0 and then change the other based on your speed*Time.deltaTime (im slightly new to coding so let me know if it works)
@@zakr2084 it's your choice if u doesn't want to copy than don't worry just understand the login and than u can make your own script but generally there are same logic I found every single time for bullet script as shown in video
Good video. You are good at explaining things. I am working on a game that uses similar enemies I used the Math functions to calculate the enemy shoot distance but I think your way is easier and efficient.
this vid really helped me make the enemy ai and gave me an idea for an enemy that i never thought about adding before enemy is called pusher pushers have a bigger line of sight, but dont do damage as the name implies, the pushers will use collision to push you which could cause you to get pushed into other enemies or deathzones
Hey! Really enjoy your videos, they are simple to follow and straight to the point. I was wondering, is there a way to make the enemies’ movements “smoother” instead of it following in a straight line?
Second part of the code is here : using UnityEngine; public class EnemyAi : MonoBehaviour { public float speed; public float lineOfSight; public float shootingRange; public float fireRate; private float nextFireTime; public GameObject bullet; public GameObject bulletParent; private Transform player; void Start() { player = GameObject.FindGameObjectWithTag("Player").transform; // FIND THE PLAYER } void Update() { float distanceFromPlayer = Vector2.Distance(player.position, transform.position); // When player goes near enemy // Will move when player in line of sight, but not move when in shooting range if(distanceFromPlayer < lineOfSight && distanceFromPlayer>shootingRange) { transform.position = Vector2.MoveTowards(this.transform.position, player.position, speed * Time.deltaTime); } else if (distanceFromPlayer
Hey for enemy 1 I get an error of 'GameObject[]' does not contain a definition for 'transform' and no accessible extension 'transform' accepting a first argument In short :I need help
Hey, I got the same issue as you. In my case the issue was that i wrote Player= GameObject.FindGameObjects... the issue was ,, FindGameObjects", but it has to be only one GameObject. Sorry for my bad English, i hope this comment helped you;)

private void FlipEnemyX() { if (transform.position.x < LastXValue - 0.1) { //Debug.Log("Decreased!"); LastXValue= transform.position.x; this.spriteRenderer.flipX = true; } else if (transform.position.x > LastXValue + 0.1) { //Debug.Log("Increased"); LastXValue = transform.position.x; this.spriteRenderer.flipX = false; } this code will flip your enemy according to its movement. At first I had 2 scripts that flip the sprite.. when enemy is following the player and when its just patrolling around but it did not work as well .. so I made this new one and it works both situations. (-0.1 or +0.1) will change make it less flipping around when near walls or something when value change is too small... play around with this.
why my enemy is jittering when he is in shooting range. Used exactly the same code you did, but I can't see this problem in this video. transform.position = Vector2.MoveTowards(this.transform.position, player.position, speed * Time.deltaTime);
Great toturial, but how can i determine when player attack enemy, then enemy keep attacking to the player, otherwise enemy go its way regardless of player
Hi Nice video , i followed it , even i got some problem i done fixed it tq for the tutorial but , Can we make the bullet can collide and destroy with environment and Player too so the Player will get damaged ?
Bro, I am making a 2d top down space shooter. There is a problem in shooting system, that is , when enemy is shooting and I shoot, then the player's bullet is colliding with enemy bullet and the player's bullet is destroyed but the enemies bullet is not destroyed. Can you tell me what to do to make the both bullets passing away without any collision.
@@salimmohsneh1990 does your bullet have rigidbody2D component? If yes and it's still happening then paste the code you wrote ok and we will figure something out
I did this on my enemy and its working perfect. Meanwhile i made a script animation ( using animation 8 static directions and 8 walking directions ) how do i call this animation script when enemy enters in range to follow? All the best tkhs in advance.
how could i make it so that the enemy turns around when the player is either left or right? please respond fast, i'm making this game that i have to finish at the end of this year and i really dont want to extend this deadline. thanks!
what do you mean how? if(enemy.transform.pos.x > player.transform.pos.x) { enemy.getcomponent().flipX or enemy.localscale.x *-1 } and do the same if the opposite is met
Hey, what if there are two targets? (In my game i have a player and a tree) i want the enemy to attack the one near it (player or tree) how can i do this :)
Take in the distance between the enemy and the player and the enemy and the tree and compare which is the smallest then make the enemy go to that object
any one knows how to set up an attack animation with the 2nd part with animation I keep stuck it keeps doing the animation over and over that is my code: private void Update() { float DistanceFromPlayer = Vector2.Distance(player.position, transform.position); if (DistanceFromPlayer < LineOfSite && DistanceFromPlayer > AttackRange) { anime.SetBool("IsRunning", true); anime.SetFloat("speed", Mathf.Abs(speed)); transform.position = Vector2.MoveTowards(this.transform.position, player.position, speed * Time.deltaTime); FlipEnemy(); } else if (DistanceFromPlayer
I know this is 11 months old, but if you haven't figured it out, try to use a .SetBool("EnemyAttack", true) on the animator when they're in range. Set it to false when those conditions aren't met. Redundant, but it might work.
For enemy 2: The projectiles doesnt follow my player, the enemy just drop it down and it disappears, I set the gravity to 0 on Rigidbody, but then it just get stuck in air. Basically it doesnt shoot towards my player, I copied the script but no idea whats wrong? EDIT: Totally my bad, I accidentally used a bullet prefab that was an ingame object with Rigidbody to it :-)

Well the concept is same but you have to change many values to make it work on 3D . Like change the overlap circle to overlap sphere,make it rotate towards the player on the z axis as well so the enemy faces toward the player and many more but yeah it will work

this vid really helped me make the enemy ai and gave me an idea for an enemy that i never thought about adding before
enemy is called pusher
pushers have a bigger line of sight, but dont do damage

i love this kind of videos stright to the point

Guys follow me on discord it will be easy to show you the code
private void FlipEnemyX()
{
if (transform.position.x < LastXValue - 0.1)

//Debug.Log("Decreased!");
LastXValue= transform.position.x;

}
else if (transform.position.x > LastXValue + 0.1)
{
//Debug.Log("Increased");
LastXValue = transform.position.x;

this code will flip your enemy according to its movement.
