How to disable and enable the prefab with normcore

Hi. I'm new to the multiplayer game.
I'd like to disable and enable the prefab in my game while running.
I'm using .SetActive() now.

How do I use normcore?
Thank you in advance for the answer.

Solution

----------------------
If you want to remove the object at index 0 after finishing the loop, you can do so by calling the

RemoveAt()

RemoveAt()

method on the list. Here's how you can modify the previous example:

using UnityEngine;
using Normal.Realtime;

public class ObjectManager : MonoBehaviour {{
    [SerializeField] private List<GameObject> _objects;

    private void Start() {{
        for (int i = 0; i < _objects.Count; i++) {{
            // Get the RealtimeTransform and RealtimeView components
            RealtimeTransform realtimeTransform = _objects[i].GetComponent<RealtimeTransform>();
            RealtimeView realtimeView = _objects[i].GetComponent<RealtimeView>();

            // Request ownership of each component
            if (realtimeTransform != null) {{
                realtimeTransform.RequestOwnership();
            }}
            if (realtimeView != null) {{
                realtimeView.RequestOwnership();
            }}
        }}

        // Remove the object at index 0 after finishing the loop
        if (_objects.Count > 0) {{
            _objects.RemoveAt(0);
        }}
    }}
}}

using UnityEngine;
using Normal.Realtime;

public class ObjectManager : MonoBehaviour {{
    [SerializeField] private List<GameObject> _objects;

    private void Start() {{
        for (int i = 0; i < _objects.Count; i++) {{
            // Get the RealtimeTransform and RealtimeView components
            RealtimeTransform realtimeTransform = _objects[i].GetComponent<RealtimeTransform>();
            RealtimeView realtimeView = _objects[i].GetComponent<RealtimeView>();

            // Request ownership of each component
            if (realtimeTransform != null) {{
                realtimeTransform.RequestOwnership();
            }}
            if (realtimeView != null) {{
                realtimeView.RequestOwnership();
            }}
        }}

        // Remove the object at index 0 after finishing the loop
        if (_objects.Count > 0) {{
            _objects.RemoveAt(0);
        }}
    }}
}}

In this example,

RemoveAt(0)

RemoveAt(0)

is called on

_objects

_objects

after the

for

for

loop. This removes the object at index 0 from the list. The

if (_objects.Count > 0)

if (_objects.Count > 0)

check is there to ensure that there is at least one object in the list before trying to remove one.

Hi @korimeily. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base.

----------------------
In Normcore, you can use Realtime prefabs which are synchronized via the Realtime API using realtime views and realtime components. To disable and enable a prefab, you would typically use the method in Unity. However, in a multiplayer setting with Normcore, you need to ensure that this change is synchronized across all clients.

To do this, you can use the Realtime API's ownership and lifetime flags. These flags give you control over which clients can modify data in your rooms. For example, you can set a flag to denote that a certain client has the authority to enable or disable a prefab.

Here's a basic example of how you might use these flags:

In this example, is a reference to the component on your prefab. This component is what allows Normcore to synchronize the prefab across all clients. The property is a boolean that tells you whether the current client is the owner of the prefab.

Remember, any changes you make to a prefab should be done through the Realtime API to ensure they are properly synchronized. For more detailed information, you can refer to the Realtime API documentation (https://normcore.io/documentation/realtime).

Please note that this is a simplified example and your actual implementation may need to be more complex depending on your game's specific requirements.

Here's how you might use these properties:

easiest method is to make a custom model with a bool for set active. when the model changed event fires you set the game object active/ inactive. but for the view to be registered it needs to instantiate active so it might be better to set a child object as inactive if you need it to start hidden

Mechabit•4/6/24, 4:38 AM

@Normcore Assistant how do i make a custom model with a bool property called setActive

kapa.ai•4/6/24, 4:38 AM

Let me check the knowledge base for you. One moment!

kapa.ai•4/6/24, 4:38 AM

----------------------
To create a custom model with a bool property called in Normcore, you would first define a class with the attribute. Inside this class, you would define a private bool field with the attribute. Here's an example:

In this example, is the name of your custom model. is the private field that will hold the value of your property. The

RealtimeProperty

RealtimeProperty

attribute tells Normcore to synchronize this field across all clients. The first argument to

RealtimeProperty

RealtimeProperty

is the property ID, which must be unique within this model. The second argument specifies whether the property is reliable (i.e., whether changes to the property should always be sent to the server, even if some packets are lost).

After defining your model, you would need to compile it. If you're using Unity 2019 or 2020, you can do this by going back to Unity, highlighting the file in your project, and clicking the "Compile Model" button in the inspector. If you're using Unity 2021 or newer, Normcore will automatically generate the remaining code needed to use your model when your project compiles.

For more detailed information, you can refer to the Creating a custom realtime component (https://normcore.io/documentation/realtime/synchronizing-custom-data) and Creating a realtime model (https://normcore.io/documentation/realtime/synchronizing-custom-data#creating-a-realtime-model) sections of the Normcore documentation.

@Normcore Assistant how do i use that model to set my gameobject active when the model changes

kapa.ai•4/6/24, 4:40 AM

Let me check the knowledge base for you. One moment!

kapa.ai•4/6/24, 4:40 AM

----------------------
To use the custom model to set your GameObject active when the model changes, you would need to create a

RealtimeComponent

RealtimeComponent

subclass that uses your custom model. In this subclass, you would override the

OnRealtimeModelReplaced()

OnRealtimeModelReplaced()

method to subscribe to changes to the property. Here's an example:

In this example, is the name of your custom component.

OnRealtimeModelReplaced()

OnRealtimeModelReplaced()

is a method that is called when the model for this component is replaced (e.g., when the component is first created or when switching rooms). is an event that is fired when the property on the model changes.

You would attach this script to the GameObject that you want to set active or inactive based on the property of the model.

I have a list that contains prefabs and I'd like to enable each prefab when I click the button. and when prefabs are active another player can see @Normcore Assistant

Let me check the knowledge base for you. One moment!

kapa.ai•4/6/24, 5:14 AM

----------------------
To enable each prefab in a list when a button is clicked and ensure that other players can see the changes, you can use Normcore's

Realtime.Instantiate()

Realtime.Instantiate()

method. This method instantiates a prefab and synchronizes it across all clients.

Here's a basic example of how you might do this:

In this example, is a reference to the component in your scene, is a list of the prefabs you want to enable, and is the button that will enable the prefabs when clicked. The method is called when the button is clicked, and it iterates over each prefab in the list, instantiates it using

Realtime.Instantiate()

Realtime.Instantiate()

, and enables it using .

Remember to add the prefabs to a Resources folder in your Unity project, as Normcore requires prefabs to be in a Resources folder to instantiate them at runtime.

To use the event of a button in Unity, you need to add a method to the button's event. This method will be called whenever the button is clicked. Here's a basic example:

In this example, is a reference to the component on your button. The method is added to the button's event in the method. This means that the method will be called whenever the button is clicked.

You can replace the call in the method with whatever code you want to execute when the button is clicked.

Mechabit•4/6/24, 5:28 AM

you add a realtime view to the parent of each prefab (it wont work on the disabled object itself as it needs to be active to register with realtime) then you set the value of the custom model i posted earlier to true when you click your ui button. e.g. model.setActive = true;
