Pure Pool and Photon Pun 2

Maverick

Is there any Demo using Pure Pool integrated with Photon Pun 2? Recently bought Pure Pool since i had this issue, but im still a little confused how the integration works.

I use in my PhotonRoom script the following instantiation RPC after loading the scene level from the main menu:
[PunRPC]
private void RPC_CreatePlayer()
{
PhotonNetwork.Instantiate(Path.Combine("PhotonPrefab", "Player"), transform.position, Quaternion.identity, 0);
}

The issue is that i dont want to make my player be in a pool, just scene gameObjects but somehow pure pool tries to fetch it dropping me a null error since it doesnt recognize the prefabID. Error occurs in this line of code in PrefabPool script (line 98):
if (this.manager.HasName(prefabId)) {
if (this.manager.TryAcquireDisabled(prefabId, position, rotation, out instance)) {
return instance;
}
So how do i select the gameObjects i want in the pool?

Any help on a demo of pure pool and photon to use it as a guide, would be much appreciated.

Hi @Maverick!

When using pooling, PUN 2 will forward all requests for objects to Pure Pool.

The prefabId must always be recognised. If the prefabId is not recognised, there wouldn't be any way to instantiate the object (whether pooled or not).

If you want to avoid using pooling for certain objects, you have a couple of options:

Add a NamedGameObjectPoolManager component and a GameObjectPoolManager component to your scene, if you don't have them already. Manually add the prefabs that you DON'T want to be pooled to the GameObjectPoolManager, using the custom inspector (drag and drop the items to the Quick Add area). Set the Initial Size and Maximum Size for these pools to 0. Set the Acquire Without Pool setting in the inspector to Create Pool.
Set the Use Resources setting in the NamedGameObjectPoolManager's inspector to true (checked). Under the Custom Pool Names heading, add the prefabId of each prefab that you'll be using (including the player), and the corresponding prefab.
With this approach, your Player object is added to the GameObjectPoolManager, but the pool will never contain any objects (its size is 0). Every time you ask the pool for a Player object, it will use Object.Instantiate.
Similarly to option 1 above, add a NamedGameObjectPoolManager component and a GameObjectPoolManager component to your scene, if you don't have them already. Manually add the prefabs that you DO want to be pooled to the GameObjectPoolManager, using the custom inspector (drag and drop the items to the Quick Add area). Set the Acquire Without Pool setting in the inspector to Instantiate.
Set the Use Resources setting in the NamedGameObjectPoolManager's inspector to true (checked). Under the Custom Pool Names heading, add the prefabId of each prefab that you'll be using (including the player), and the corresponding prefab.
With this approach, your Player object is not added to the GameObjectPoolManager and so no pool exists for it. This means when PUN asks to instantiate it, Pure Pool will do so using Object.Instantiate.
Manually make changes to the PrefabPool.cs class. This class can be found in the Assets\Umbrace.Unity.PurePool\Integration Libraries\Photon Unity Networking\Version 2 folder. The Instantiate method is called by PUN when you call PhotonNetwork.Instantiate. You can choose to bypass pooling for certain prefabs according to their prefabId, for example, you could add this to the start of the method:
```
if (prefabId == Path.Combine("PhotonPrefab", "Player")) {
	return Object.Instantiate(Resources.Load<GameObject>(Path.Combine("PhotonPrefab", "Player")), position, rotation);
}
```

Options 1 and 3 are ideal when you only have a small number of objects that shouldn't be pooled, and the rest should be. If you have a lot of objects that should not be pooled, and only a few should be, then option 2 may be preferable.

Let me know if you need any further guidance on this!

Kind regards,
Mark
