@NightRunStudio

Жыл бұрын

Unless I’m misunderstanding, the same script should work for all friendly units. As long as they are all tagged as Player, the enemies should only deal damage to the specific player that they collide with. So long as each player has its own copy of the script, then they should each keep track of their own health. For larger games you might eventually want one script to manage all health, but this method should work for most projects.

Hey im trying to do this in 3D and all is working okay but for some reason the collisions seem a little off, if i stand still the "enemy" walks over to me and will collide with me but i wont always lose health, i have to walk into the enemy for my health to go down. i have tried messing with the capsule colliders for the player and enemy but nothing seems to be fixing it. would there be a way to code in to take damage if the enemy is within a range of the player's collider and if so how would i code this? (im super new to coding)

@NightRunStudio

Жыл бұрын

Collisions are a bit of a fine science. Getting them just right is tricky. You can definitely code to detect nearness to the player, but it’s not the most efficient way to do it in this case. If you want a larger range than you collider currently provides, one option is to add another collider, make it a trigger (so it doesn’t bump into things), and then have your damage detect OnTriggerEnter instead of Collision. Then you can make the damage range as large as you want. Also, remember that this will only trigger on entering the collider. So if the enemy stays in the collider, it will not fire multiple times. To fix this, you would add a knock back effect, that moved the player out of the collider, or use OnCollisionStay with a timer to trigger more damage if the enemy stays inside your collider. I hope that helps!

@NightRunStudio

The problem is probably connected to the prefab that you are spawning in. When the enemy spawns in, he doesn't have the reference to the player (and you can't drag in the reference, because the enemy isn't in the game yet, so Unity wont let you). In order to get a game object script to "talk" to a prefab, you need to have it search for that object. Most often, I do this by placing the following code in the Start() function: playerHealth = GameObject.Find("Player").GetComponent(). Now, the prefab will look for an object called "Player" (or whatever the name of you object is). Once it finds that object, it will search the object to find the Component you need. Note: if your playerHealth script is on a child object, then change GetComponent to GetComponentInChildren. I hope that helps!

I'm almost done but when I get to the step around 6:30 I can't drag my player in, just get the white circle with red edge and diagonal line. Could it be because the enemy is a prefab which I'm spawning in? Or because my player is a prefab I dragged into the hierarchy? What's interesting is that the player within the game doesn't take damage, but the player in my prefab folder does. Edit: I remade my player prefab as a new game object but I still can't drag it into the enemy's damage slot

@NightRunStudio

Жыл бұрын

The problem definitely seems to be connected to the prefab--you are correct! Your prefab is just a model of the player, so when your player spawns into the game, it is NOT the prefab, but a copy. This makes things difficult, because you can't use the drag method that I suggest in the video. That said, this is a great chance to learn how to code objects to find their references (which you have to do A LOT as you get into more complex code). In order to get a game object script to "talk" to a prefab, you need to have it search for that object. Most often, I do this by placing the following code in the Start() function: playerHealth = GameObject.Find("Player").GetComponent(). Now, the prefab will look for an object called "Player" (or whatever the name of you object is). Once it finds that object, it will search the object to find the Component you need. Note: if your playerHealth script is on a child object, then change GetComponent to GetComponentInChildren. I hope that helps!

hello, I have a question. I have put the damage script on the player so when the player touches enemy it damages him but it only works on the first collision. when they collide more than once it doesnt damage player anymore. I also tried using OnCollisionStay2D but it has the same effect.

@NightRunStudio

Ай бұрын

You are on the right track! That should work, you just have to code the bullet to find the player. My more recent playerHealth video shows this (in case you want to see it explained), but here's what you need to make it work: In your OnCollisionEnter() method for the damage script, have it check any object it hits to see if it is the player, and if it is, have it fill the playerHealth variable with the object it just hit (ie., the player). private void OnCollisionEnter2D(Collision2D collision) { // Attempt to get the PlayerHealth component from the collided object if(collision.gameObject.TryGetComponent(out PlayerHealth playerHealth)) { // If the PlayerHealth component is found, assign it to the class variable this.playerHealth = playerHealth; } } I hope that helps!

@@NightRunStudio I have a similar issue with my enemies being prefabs. The code that won't work, isn't damage being given to the player, but that I have 3 hearts in the top left that represent the players health (Player loses a heart every time it takes damage. The Player is damage when the enemy touches the Player). However since the enemies are prefabs, it won't allow me to put in the "Health Controller" object (which shows the images for the hearts and the hearts get removed each time the Player taking damage). The "Health Controller" is in my Hierarchy as a child under the Player (I just found out today that prefabs cannot reference Scene Objects). If I drop an enemy object in to the Scene, it works, but the idea is that the enemy prefabs continuously spawn on the edges of the map and move towards the player rather than starting out in the scene. Not sure how I can get the prefabs to perform the "Health Controller" to remove a heart when they deal damage to the player. (Sorry, very new to coding, so hopefully this makes sense)

hi there! thank you so much for the tutorial, it's helping me out a lot for a project i have due. i've quite literally never worked with code before and it's been daunting. i do however have a question alright - i've looked at every single comment on this page and have still not been able to find out what my problem is despite so many other commenters having the exact same problem I'm having: my prefab enemy (a meteor with the enemy script) is unable to accept the fill in field from my player (a spaceship, tagged UFO) and thus whenever i hit play, there is no collision and there is no damage taken from my player ship. i've inserted the "find component for player health" in the start function of the enemy script attached to my enemy prefab as ive seen the solution be for a few other people. my prints arent registering. this is the error I get when playing: "NullReferenceException: Object reference not set to an instance of an object EnemyDamage.Start () (at Assets/EnemyDamage.cs:15)" which I don't know what this means - i know that enemy damage is not set to an instance of an object because i can't fill the inspector with the player script. i'm not sure if i explained that well enough - i can def rephrase if necessary and i can share my code if you'd like to see it as well. again, thank you so much for your tutorials, really appreciate them and how it's expanding my understanding.

It definitely sounds like you’ve identified the problem. The null reference sounds like it is on line 15 of your code, and it sounds like it’s the reference to your player health that is coming up null. The reason you can’t drag the PlayerHealth into that slot is because both objects have to be in the scene before they can start talking to each other. The get component call should work, so I suspect it may be something to do with the way you are calling it. Feel free to share that line of code, or to pop into my discord server for a better discussion forum (link is in the profile).

That usually means a spelling or capitalization error. The name in your script needs to exactly match the name of the script you are talking to. Sometimes this happens after renaming a script… sometimes when you rename, Unity doesn’t actually change the name in the script itself. Definitely double check that both the script in Unity and the script itself have the same class name. I hope that helps!

I'll need a little more information, but I'd be happy to help you troubleshoot. My first thought is to put a debug.log at the top of your OnCollision method, just to make sure that the collision is, in fact, registering. Something like: Debug.Log("Just collided with " + collision.gameObject.name): That should print the name of the object you collide with in your console. If it doesn't, you know it's probably a problem in your inspector. If it DOES print, then we know the collisions, are working and it's a code issue.

If you are working with 3D colliders, you can just use OnCollisionEnter (instead of OnCollisionEnter2D). The key is to make sure that your function call matches the type of collider you use (2D collider gets OnCollision2D, and 3D gets regular OnCollision call).

If you want the child to set the position of the parent object, you'll have to add that to the code.

@NightRunStudio

8 ай бұрын

I'll start with the radius as that is most simple. I would recommend creating a large collider around your enemy (I like circle collliders) that represents their damage range. Then, use OnTriggerEnter2D as the method in your code (you can use this instead of OnCollision, or in addition to it). Place your damage logic in the OnTrigger method. Now, whenever the player enters that trigger, it will call the damage logic.

@NightRunStudio

8 ай бұрын

The delay is a little more complex, so I wont be able to explain the details here, but I'll point you in the right direction. For this one, you will probably want to use a coroutine. When the player enters the trigger, call StartCoroutine. Then, you create a coroutine (like a normal method, but these allow you to pause time). You would put all of your damage logic in the coroutine, but first add yield return new WaitForSeconds(2); this would pause the script for 2 seconds before moving on to the damage part. I hope that helps you get started!

For some reason if my function isn't in the update it doesn't work, and putting it in the update kills the player almost immediately because he loses health the second he colides with the enemy collider.

Yeah... you definitely don't want to put it there (then it runs like 60 times per second). There must be another reason that it's not being called. Do you want to copy/paste your code here, and I'll take a look?

I am sorry in advance, my code is kind of long.

@@NightRunStudio Yes, i checked with the debug

First, thanks for these videos. Unfortunately it didn't work with what I was trying to apply it to even as a test. I have a Game Controller that if the player is hit with a Destroy by Contact (shots, enemies, hazards) the Player health bar would drop with each impact. Right now one collision ends game till Restart. I wanted to try and set it so once Health is empty or 0, there would be taken away 1 life (IE heart Icon) and reset health bar to 100 with each remaining life. Then when all the lives are exhausted (say 3) and the health has reached zero, then the game is over, and you have to restart. SO I need some sort of simple and straightforward way to reference all three scripts properly. The Player Heath, the Destroy by Contact, and the Game Controller. I have tried several Health systems and not a single one works with the other two scripts and certainly does nothing to tick away the heath bar much less any spare lives. Been trying to do this for days spending 12+ hours just to find something that will work properly.

Hmmn...I have a couple of thoughts... First: Is your Destroy script auto-destroying, or is it just that your collisions are being mult-triggered, so that you lose multiple health each time you collide? If you have multiple colliders on your player (or on child objects), it's possible all of these are triggering each time you get hit. Second: Sounds like you need to create a "Lives" int in your Game Controller. Then, rather than destroying your player each time he reaches zero, you could have your Destroy script tell the Game Controller to take another life. This would look something like: if(PlayerHealth.health

if you want to put this in 3D the enemy damage should be this using System.Collections; using System.Collections.Generic; using UnityEngine; public class EnemyDamage : MonoBehaviour { public PlayerHealth playerHealth; public int damage = 10; private void OnCollisionEnter(Collision collision) { if(collision.gameObject.tag == "Player") { playerHealth.TakeDamage(damage); } } }

If you're working in 3D, you will need to make sure that you are using regular colliders, and that your code is OnCollision as opposed to OnCollision2D. That would be my first guess without more information. Feel free to DM me on Twitter if you want to send some screenshots or anything like that.

@@CarlozYT Gotcha. The reason you can't drag the player in is because the bullet is a prefab (which means it doesn't exist in the scene until you instantiate it). The way around this, is the have the bullet find the PlayerHealth script once it is instantiated. In the bullet script, go to the Start() function. You will need to type: playerHealth = GameObject.Find("PlayerName").GetComponent(); This will let the bullet fill the box by itself. It will find the player (make sure to type the exact name of your player), and then find the script on your player. I hope that helps!

Anytime you see that error it is telling you that you forgot to define a variable reference. In this case, I'm willing to bet it's your playerHealth variable. The script knows it hit your player, and now it wants to talk to the playerHealth script, but it doesn't know where to find it. To fix this, just drag your player into the PlayerHealth slot in the enemy's inspector (I do this around 6:22 in the video). Hope that helps!

The code looks all good. Must be an issue in Unity. Does either your player or the enemy have a rigid body 2d? (One has to or the collisions won’t detect). Also, did you make sure that both have 2D colliders? And that the colliders are not triggers? Just a few things to check to get you started.

If you click on the error message, it should take you to the line that is causing the problem. A null reference just means that your script is looking for something but can't find it (often this is a reference to another script). Once you know what it's missing, it will be easier to figure out why it can't find that reference.

Now the error does not appear anymore, but when the player is destroyed by the enemy, the message appears: "The object of type 'GameObject' has been destroyed but you are still trying to access it. Your script should either check if it is null or you should not destroy the object." This message refers to my Enemy's AI. I'm guessing there's a situation where my player disappears.

@@aleksandraaleksandra7934 I'm so glad you are finding the videos helpful! Thanks for sharing. The null reference probably has to do with your character being destroyed, but the game is still trying to talk to scripts on your player. As your game develops, we generally move away from destroying the player on death (for this reason), and instead turn off specific elements of the player (like your sprite and movement scripts). For the moment, those errors should cause any serious problems (since your player is dead anyways). I hope that makes sense. Good luck as you continue to learn!

I fixed this problem. It turned out to be due to a reference to the player object in an old script that was unused and became an artifact. So a protip for everyone who makes a game: organizing your scripts is important! :-). If you get a similar error, it's worth looking at the script that the console message sends you to and see where the script refers to the player object. Either it will be a mess like mine or you may need to add TakeDamage() in this script. I'm not sure about the second solution!
