Looks great. if you would ever want to work on someting that can be marketed then let me know. 

Great work 

I use unreal engine too, do you happen to know how to set up an array using Widget blueprints?  I want my npc to pop up a different widget whenever I step into the on overlap trigger area so your npc gives you random greetings.

I'm doing a non commercial game, but I don't know how to set up the string array up in Unreal Engine Blueprints.  As I can't use the text string node as that's for debugging purposes only so It wont show up in the game.    I don't yet know how to draw text randomly in the widget so I'm interested in learning how that's set up, then once I know how to do that, then i can assign the sound file.

Moving over from simple windows script over to Unreal Blueprints was a big change to make.  

I also have to find out how to get the Trace Weapon I got working in the unreal weapons level map I made to actually do Damage to the droids and record the number of droids that are still remaining.  I haven't figured this part of the code yet.  So there are still some things in the blueprints I haven't figured out as I'm new to this blueprint scripting stuff.

I use the arrays in windows script for doing random greets, determining what's inside the chests when you get to the chests areas, use them for setting specific conditions or events in the game, determing the value of credits what loot enemies should drop when you kill them, determining the branches of dialog for npc's to take, which dialog to pop up if the party member exists and so on, so for me the array is useful for a huge range of tasks.   I also need to find someone to rig loana up for me for unreal engine as well.  I have got the blender model but I need to get her rigged.

Here's the game project i'm working on: http://www.tozan35.weebly.com

But Any help in getting a basic array up and working in blueprints would be much appreciated.   My game uses a basic slots system with random intergers to determine the outcome of the choice.  That makes  it kinna self-procedural in a way alowing the computer to now make the choices for the NPC's behavior and responses. (giving them Artificial Intelligence).

I created the game script text as a foundation so i would have a plan to go by when it came to actually building up all the 3d worlds of the game in the Unreal Engine.

Here's how I set the array up in windows script for doing NPC dialog responses.

set /a spin=%random% %%3+1 

if %spin% EQU 1 echo. Storm: Drat, my plan didn't work.  I was hoping to bribe him. 

if %spin% EQU 2 echo. Storm: Curses, I thought it would work on him.  

if %spin% EQU 3 echo. Storm: I'll have to try something else. 

 Now I just need to know how to convert this little piece of script code into blueprint code because the  game dialog is nested up inside all of these arrays.   

Nice Prototype! great work!
