AR Plane Detect Advanced

https://github.com/labatrockwell/xr-research/blob/AR/Multi_User_Demo/Assets/Scenes/AR/Photon/Lobby/Lobby%20Place%20Object.unity

Prerequisites

1. Network Manager New Script - returns true when the room is joined
2. Networked Image Anchor Script - hides the object container till the image is found

Function

Refer to this project for

1. choosing between multiple objects
2. plane detection

This sketch lets multiple players place objects on detected planes. They can choose between three objects - spheres, capsules and cubes. Each player’s objects have a unique color.

Details

Object Selection

From Button Clicker.cs using buttons to change which object should be drawn. For photon initialising objects, you need to pass a string instead of the object prefab. So, clicking on the button just changes a string. In this example, the 3d objects are saved as “Torus”, “Sphere”, “Cube” in Assets/Photon Prefabs

void Start()  
{  
    torus.onClick.AddListener(delegate {TaskWithParameters("Torus"); });  
    sphere.onClick.AddListener(delegate {TaskWithParameters("Sphere"); });  
    cube.onClick.AddListener(delegate { TaskWithParameters("Cube"); });  
}  
  
void TaskWithParameters(string message)  
{  
    shape = message;  
}

Player Color

Using ActorNumber to set the color of the objects

private Color SetPlayerColor()  
{  
    int playerId = PhotonNetwork.LocalPlayer.ActorNumber;  
    float r = (playerId * 0.3f) % 1f;  
    float g = (playerId * 0.5f) % 1f;  
    float b = (playerId * 0.7f) % 1f;  
    return new Color(r, g, b);  
}

Next Steps:

1. using the image anchor similar to in AR Drawing for colocation.
