Hololens Sharing using custom message

holofearless

Thank for the Holograms 240 tutorial that I am able to share the hologram between devices using hologram (energyhub) and code in this example. To take my understanding a bit further with sharing interaction of user, I modify the CustomMesages and public class ProjectileLauncher to see if my understanding is correct. Here is what I did
Add one more message type to TestMessageID enum called "test"

public enum TestMessageID : byte
    {
        ...
        Test
    }

Replicate function SendShootProjectile() and called it SendShootProjectileTest()

public void SendShootProjectileTest(Vector3 position, Vector3 direction)
    {
             //Everything is the same as in SendShootProjecttile() function
             ...
            // Instead of create mesage using TestMessageID.ShootProjectile, I used             TestMessageID.Test to test
            // Create an outgoing network message to contain all the info we want to send
            NetworkOutMessage msg = CreateMessage((byte)TestMessageID.Test);

           // Same as  s in SendShootProjecttile() function
           ...
    }

Now in ProjectileLauncher.cs I modify two things
a. Instead of:

CustomMessages.Instance.MessageHandlers[CustomMessages.TestMessageID.ShootProjectile] = this.ProcessRemoteProjectile;

I change to this:

CustomMessages.Instance.MessageHandlers[CustomMessages.TestMessageID.Test] = this.ProcessRemoteProjectile;

b. Under function SpawnProjectile() inside ProjectileLauncher.cs, instead of calling

CustomMessages.Instance.SendShootProjectile(anchor.InverseTransformPoint(ProjectilePosition), anchor.InverseTransformDirection(ProjectileDirection));

I call this:

CustomMessages.Instance.SendShootProjectileTest(anchor.InverseTransformPoint(ProjectilePosition), anchor.InverseTransformDirection(ProjectileDirection));

I then build and deploy the app to devices, the anchor sharing work ok but when the user tap to send out shoot projectile, using debug, I see the message of type "test" are broadcast under SendShootProjectileTest() function of file CustomMessages.cs, but the message is not received by other devices. I place a break point in function ProcessRemoteProjectile() in ProjectileLauncher.cs and don't see it hit.

If I get rid of all the above changes, and I run the app on devices, I see it the message type "ShootProjectile" are broadcast and then received by other devices.

I thought this whole process is simple and really straight forward, it should work but it not.
Do I miss anything?
Thank you for any help.

Further testing give me the result that if you add a new MessageID won't work but if you modify the existing MessageID such as "ShootProjectile" to "ShootProjectileTest" then it works. It is kind of weird

Well, finally I think I know the reason. Don't add new message ID below "Max" but do add new message ID above it if you need a new message.
