Hei everyone.
I am new to Unity Network and tried to send a Texture over Network but it didn’t worked for me, even with tutorials.
Now I try to send the Webcamtexture to a local second Texture to figure out how it works. I get it simple with texture2.SetPixels(webcamTexture.GetPixels32()) but i try to convert the Webcamtexture into bytes in a struct to send this over Network as soon as it works locally.
I created a struct and in there a function to set the rgba to single bytes and want to save these structs in a SycnListStruct.
I createt a public class SyncListWebcamdata which inherit from my SyncListStruct and made a instance of it.
On running i get following Error Message:
UNetWeaver error: SyncListStruct member variable [UnityEngine.Networking.SyncListStruct`1 SendWebcamTextureToAnotherTexture::webcamDataList] must use a dervied class, like “class MySyncList : SyncListStruct {}”.
Hope you can help me figure this out.
And is somebody known with the Plugin VideoChat on the Asset Store https://www.assetstore.unity3d.com/en/#!/content/7447 ?
Is it worth to buy it or should try to make it on own?
