Blueprint Dialogue System

Let me walk you through my steps.

This applies to 4.17.2 and 4.18.1

I fresh install a template ( I have tried with top down and 3rd person ).
I migrate the dialogue folder to my content.
I open the sample and play - everything works fine
I create my own dialog from the demo given in the video and I am unable to execute the event (“Press E to…”)

I have gone into your controller and looked at the was you are scanning for events and checking the buttons and such so I try to use that but still no luck.

I guess my problem is that I am, as of now, unable to integrate this into my existing project from scratch.

Ah ok, I’ll go through some possible problems and maybe I’ll scratch the issue.

• The default collision channel for the UseScanner is the Visibility channel. Make sure the actor handles this trace channel as **block **(overlap might also work), or change the UseScanner to use a different channel that is handled this way.
  NOTE: Characters in UE4 have a default visible channel of ignore for some reason. (anecdote) I have changed this in my projects with hundreds of characters without noticing a difference - no idea why it’s the default.

• Make sure **ScanForUsables **in BPC_UseScanner is being called (set a breakpoint at the start of the function). If it’s not called, either make sure the tick is enabled on the component, or ScanForUsables is called manually.

• Make sure that your Use input is being called properly
  **Note: **The message “Press E to Use” is a debug print message in the sample, these don’t print in packaged builds
