uOSC is an OSC implementation for Unity.
- Windows
- Mac
- HoloLens
I've not checked Android and iOS yet...
Download the latest .unitypackage from Release page
and import it to your Unity project.
- Attach
uOscServercomponent to GameObject. - Register
uOscServer.onDataReceivedevent.
using UnityEngine;
using uOSC;
public class ServerTest : MonoBehaviour
{
void Start()
{
var server = GetComponent<uOscServer>();
server.onDataReceived.AddListener(OnDataReceived);
}
void OnDataReceived(Message message)
{
// address (e.g. /uOSC/hoge)
var msg = message.address + ": ";
// arguments (object array)
foreach (var value in message.values)
{
if (value is int) msg += (int)value;
else if (value is float) msg += (float)value;
else if (value is string) msg += (string)value;
else if (value is byte[]) msg += "byte[" + ((byte[])value).Length + "]";
}
Debug.Log(msg);
}
}onDataReceived is called from the Unity main thread, so you can use Unity APIs inside it.
OSC Bundle is automatically expanded, and each message comes to
the onDataReceived event handler directly, so you don't have to check
whether the value is a OSC Message or OSC Bundle.
- Add
uOscClientcomponent to GameObject. - Send data (
int,float,string, andbyte[], are supported now).
using UnityEngine;
using uOSC;
public class ClientTest : MonoBehaviour
{
void Update()
{
var client = GetComponent<uOscClient>();
client.Send("/uOSC/test", 10, "hoge", 1.234f, new byte[] { 1, 2, 3 });
}
}If you want to start and stop uOSC in runtime, please toggle the enable flag of uOscServer or uOscClient.
This is an example to send texture data to a remote host.
using UnityEngine;
using uOSC;
public class ClientBlobTest : MonoBehaviour
{
[SerializeField]
Texture2D texture;
byte[] byteTexture_;
void Start()
{
#if UNITY_2017
byteTexture_ = ImageConversion.EncodeToPNG(texture);
#else
byteTexture_ = texture.EncodeToPNG();
#endif
}
void Update()
{
var client = GetComponent<uOscClient>();
client.Send("/uOSC/blob", byteTexture_);
}
}using UnityEngine;
using uOSC;
namespace uOSC
{
public class ServerBlobTest : MonoBehaviour
{
Texture2D texture_;
void Start()
{
var server = GetComponent<uOscServer>();
server.onDataReceived.AddListener(OnDataReceived);
texture_ = new Texture2D(256, 256, TextureFormat.ARGB32, true);
var renderer = GetComponent<Renderer>();
renderer.material.mainTexture = texture_;
}
void OnDataReceived(Message message)
{
if (message.address == "/uOSC/blob")
{
var byteTexture = (byte[])message.values[0];
#if UNITY_2017
ImageConversion.LoadImage(texture_, byteTexture, true);
#else
texture_.LoadImage(byteTexture);
#endif
}
}
}OSC Bundle has timestamp, and you can use it as DateTime as below:
using UnityEngine;
using uOSC;
public class ServerTest : MonoBehaviour
{
...
void OnDataReceived(Message message)
{
var dateTime = message.timestamp.ToLocalTime();
}
}You can merge multiple OSC messages into a bundle as below:
using UnityEngine;
using uOSC;
public class ClientBundleTest : MonoBehaviour
{
void Update()
{
var client = GetComponent<uOscClient>();
// Bundle (root)
// - Bundle 1 -> Now
// - Message 1-1
// - Message 1-2
// - Message 1-3
// - Bundle 2 -> 10 sec after
// - Message 2-1
// - Message 2-2
// - Message 2-3
// - Message 3 -> Immediate
var bundle1 = new Bundle(Timestamp.Now);
bundle1.Add(new Message("/uOSC/root/bundle1/message1", 123, "hoge", new byte[] { 1, 2, 3, 4 }));
bundle1.Add(new Message("/uOSC/root/bundle1/message2", 1.2345f));
bundle1.Add(new Message("/uOSC/root/bundle1/message3", "abcdefghijklmn"));
var date2 = System.DateTime.UtcNow.AddSeconds(10);
var timestamp2 = Timestamp.CreateFromDateTime(date2);
var bundle2 = new Bundle(timestamp2);
bundle2.Add(new Message("/uOSC/root/bundle2/message1", 234, "fuga", new byte[] { 2, 3, 4 }));
bundle2.Add(new Message("/uOSC/root/bundle2/message2", 2.3456f));
bundle2.Add(new Message("/uOSC/root/bundle2/message3", "opqrstuvwxyz"));
var root = new Bundle(Timestamp.Immediate);
root.Add(bundle1);
root.Add(bundle2);
root.Add(new Message("/uOSC/root/message3"));
client.Send(root);
// Then, client will get 7 messages in onDataReceived event.
}
}If you want to increaset the size of buffer, please edit the uOscClient.BufferSize directly (default is 8192).
