# Migrating a project from UNet (HLAPI) #
|
|
|
|
This guide gives you a step by step instruction for migrating your project from HLAP to Mirror.
|
|
Mirror is a fork of HLAPI. As such the migration is straight forward for most projects.
|
|
|
|
## 1) BACKUP ##
|
|
You have been warned.
|
|
|
|
## 2) Install Mirror ##
|
|
Get Mirror from the asset store and import it in your project (link to be provided)
|
|
|
|
## 3) Replace namespace ##
|
|
|
|
Replace `Unity.Networking` for `Mirror` everywhere in your project. So for example, if you have this:
|
|
```
|
|
using Unity.Networking;
|
|
|
|
public class Player : NetworkBehaviour {
|
|
...
|
|
}
|
|
```
|
|
|
|
you would replace it with:
|
|
```
|
|
using Mirror;
|
|
|
|
public class Player : NetworkBehaviour {
|
|
...
|
|
}
|
|
```
|
|
At this point, you might get some compilation errors. Don't panic, these are easy to fix. Keep going
|
|
|
|
## 4) Remove all channels ##
|
|
As of this writing, all messages are reliable, ordered, fragmented. There is no need for channels at all.
|
|
To avoid making misleading code, we have removed channels.
|
|
|
|
For example, if you have this code:
|
|
|
|
```
|
|
[Command(channel= Channels.DefaultReliable)]
|
|
public void CmdMove(int x, int y)
|
|
{
|
|
...
|
|
}
|
|
```
|
|
|
|
replace it with:
|
|
```
|
|
[Command]
|
|
public void CmdMove(int x, int y)
|
|
{
|
|
...
|
|
}
|
|
```
|
|
The same applies for `[ClientRPC]`, `[NetworkSettings]`, `[SyncEvent]`, `[SyncVar]`, `[TargetRPC]`
|
|
|
|
## 5) Rename SyncListStruct to SyncListSTRUCT ##
|
|
There is a bug in the original UNET Weaver that makes it mess withour Mirror.SyncListStruct without checking the namespace.
|
|
Until Unity officially removes UNET in 2019.1, we will have to use the name `[SyncListSTRUCT]` instead.
|
|
|
|
So for example, if you have definitions like:
|
|
|
|
```
|
|
public class SyncListQuest : SyncListStruct<Quest> {}
|
|
```
|
|
|
|
replace them with:
|
|
```
|
|
public class SyncListQuest : SyncListSTRUCT<Quest> {}
|
|
```
|
|
|
|
## 6. Replace Components ##
|
|
Every networked prefab and scene object needs to be adjusted. They will be using `NetworkIdentity` from Unet, and you need to replace that componenent with `NetworkIdentity` from Mirror. You may be using other network components, such as `NetworkAnimator` or `NetworkTransform`. All components from Unet should be replaced with their corresponding component from Mirror.
|
|
|
|
Note that if you remove and add a NetworkIdentity, you will need to reassign it in any component that was referencing it.
|
|
|
|
## 7. Adjust your firewall and router ##
|
|
LLAPI uses UDP. Mirror uses TCP by default. This means you may need to change your router
|
|
port forwarding and the firewall on your machine to expose the TCP port instead of UDP.
|
|
This highly depends on your router and operating system
