I’m at the end of this lecture and i get a failure when trying to package, it’s something with the ReplicationComponent; I guess that NeedInitialization but i tried adding the Initialize method to the component but didn’t work

Have you got live coding turned on? if so, turn it off and close the editor.
Delete the binaries folder and then launch the project again.

The error is pointing to your replication component so that to me indicates there’s a issue with the code. Sometimes live coding doesn’t report errors correctly and is quite unstable.

Give this a try and you may find there’s a compile error. The Package Compiles in a similar manner to a build when live coding is off so I’d expect to see the same issues.

Let me know how you get on.

DId exactly as you said and it packaged just fine, thanks.

I’m trying to solve another issue, maybe you can point me in the right direction if you got time, i’m now making the Main menu host button create/host a map where the car should be used, but when i spawn there after ServerTravel i cannot control my car

#5

Shows a full screen and no car???

possibly not enough network spawn points. This is covered somewhere.

#6

Shows a car but i cannot move it, i guess something input related

#7

I would check your input event handlers. Also, it could point to an issue with the replication component which might prevent movement if not set up correctly.

#8

works on client and not on server

#9

That doesn’t matter so much. All moves have to be replicated to the server. Add some log messages to be sure to see where the code is running. It is probably related to certain IF statements that check where the code is running.
