This is the only tutorial I've found that explained everything in most simple terms and in under 5 minutes. I'll download this video for future reference. Thanks! :)

You could also make the pool expandable in case it hits that upper limit: if (canExpand) { //All pooled objects in use. Create a new one, add it to the pool, then return it. GameObject instance = Instantiate(prefab); instance.SetActive(false); pool.Add(instance); return instance; } else { return null; }

@@dcry1003 In case if others need a solution. you create a class, then call the class before start function as an array. Basically you do the same but each time you just do for loops [System.Serializable] public class PoolList { public List pooledObjects = new List(); public int amountToPull; public GameObject EnemyPrefab; }

Great tutorial! Clean, straight to the point and even shows a practical example. Well done :D

This helped me with my project for my scrollRect items and significantly made it faster! Thank you!

Great tutorial! Awsesome to use a simple example like this to illustrate the concept, very well done!!

this is probably the best and most simplest tutorial on object pooling, loved it.

Amazing. Thank you so much for the tutorial. It's really clean and helpful.

This is a great video to easily reference for small project implementations, thank you.

Thank you so much for this great tutorial :)

You don't how much I appreciate this video. I thought the 'SetActive(true)' must be on the start method of the bullet. Somehow it never sets to true. Finally, after 5 hours of googling and watching videos I can say your video is the best. Very short and straight to the point. Thank you so much!

Love how simple you make it.

Em 4 minutos o cara explica uma aula de 30 minutos, inacreditável. Obrigado

Great tutorial!

Great Explanation

excellent tutorial!

This solution it's "Fine", but if you enable too many bullets the fps are gonna tank either way. That's because everytime you want to spawn a bullet the code >Does a forloop >Checks if the gameobject is disabled I tell you this because it happened to my when I tried to make a bullet hell game, this solution it's really bad for that since after 1k bullets the CPU starts to tank. Sadly the best solution i've found it's convoluted and uses like 6 different arrays but it reduces the forloops to only 2 (You could make it 1 but I got lazy) after the object pool spawns every object at least once and it doesn't need to check if the object is disabled because it always is.

Thank you very much!

Fantastic. Is object pooling good for enable/disable coins to get performance? I believe you can Do this with many objects that are in a game scene dozens of times.

I am using Unity 2021.3.4f1 (LTS) and getting this error when trying to declare 'public static ObjectPool instance;': CS0246 The type or namespace name 'ObjectPool' could not be found (are you missing a using directive or an assembly reference?) . I am not sure if I need a to use a different Unity class other than UnityEngine in my newer version, but please help.

this is pool but not proper pool like if you have bullet moving with rigid body and your using this method once bullet spawned then its rigid body movement is set to specific amount then when you set active it as false and then respawn bullet then rigid body will be the last time movement set to it then its movement got disturbed and here's is solution if you set the velocity zero again and respawn it it will be spawned with zero velocity and have to set velocity again so object pool can work better if you used queue or you can add objects and then remove it like get those objects after setting it as false when you add it to queue again it will be like new object i hope im not wrong please correct me

What if you get a reference of ObjectPool to the Player script? I am asking that because I don't see the usefulness of Singleton in this example.

This is a pretty clean tutorial. Thank you. For real, really good. I´ve got a problem and after hours and hours (you know the drill) I decided to come here. The problem is once my bullet is not active (2s timer BulletBehaviour script) I can't use the pool anymore. If i fire fast, i get to use a lot of bullets from the pool, but once any bullet timer is reached, that's it, can´t use any more bullets from the pool. Please, please, help me. I am almost returning to the old instantiate and destroy.

@@bendux Deleted the code and returned to the old method... I will remake it now that you are willing to help. But I literally copied your stuff, even the names. This make 0 sense. I´m trying to make a topdown shooter, so i also get the position and angle from the firepoint, but that's pretty much everything different from the video. There are three scripts. BulletBehaviour that, for now, counts from 2 to 0. When it reaches 0 the bullet is set to be inactive. I think the problem is there. Since the script is pretty short, I will copy it here. float life = 2; // Update is called once per frame void Update() { if(life > 0) { life -= Time.deltaTime; } else { //Destroy(this.gameObject); gameObject.SetActive(false); } } The pooling script is a copy of yours. The spawning script also uses pretty much your logic. Used a Debug.Log to see if the problem was making the bullet a child of the canvas. Didn´t seem like it, problem stayed even if this line was //.

I feel like people who search for object pooling already know why it's good and you spent the first 60 seconds for nothing. I'm planning to start a channel like yours. 200 views seem so low for the effort. Maybe this is not the most popular topic. Good luck if you still do youtube, Idk honestly 3 months passed. Also, id like to know why you started youtube? to market your indie games?
