Pixel Crushers Forum

Hello,

I'm trying to use C# as my primary programming source, as I'm more comfortable with it than Lua. But I'm not sure how to go about this, and there's not a lot of information that I can find on the wiki or this forum. I did find this function that adds custom functions to the Lua layer. But as far as I can tell, they're added at runtime, meaning I can't use the Lua wizard to add conditions/scripts to dialogue nodes unless I type them by hand.

I also found that there's the "Custom" condition/script choice, but I've had trouble finding any information on how to use that, and the dropdown is blank by default. Maybe that's related, maybe it's not.

Am I missing something? Or doing this wrong?

Thanks

Hi,

That link points to the (extremely old) legacy version 1.x documentation. Please use the version 2.x documentation available here:

Dialogue System Manual

You can write your code in C# and then use Lua.RegisterFunction() at runtime. It's easiest to start with the template script located in Plugins / Pixel Crushers / Dialogue System / Templates / Scripts.

Then create a Custom Lua Function Info asset in your project. (Create > Pixel Crushers > Dialogue System > Custom Lua Function Info.) In this asset, you can define your functions' signatures -- that is, what parameters it accepts, and what value it returns. These will appear in the "..." Lua dropdown wizards.

Helpful links:

• Lua / Logic
• Registering C# Functions with Lua
• Custom Lua Function Info

Thank you! I'll check these out.

Hello -

I seem to be having a problem getting the example script to work. I've followed the steps in the links provided and got so far as being able to add "DebugLog(string)" to the Scripts portion of a dialogue node via the Scripts Wizard. Presumably this means the Lua Register function worked properly. I added a basic string, "Ope", to make sure I got everything right. However, when I click on that dialogue node in-game, nothing is registered to the console.

Any ideas on what I'm missing?

Thanks

Hi,

Did you add your C# script to the scene (e.g., to the the Dialogue Manager)? Or otherwise set it up so that the Lua.RegisterFunction() method will be executed?

I did. I added the example script as a component attached to the Dialogue Manager gameobject. The Lua.RegisterFunction() I use is called in Start().

Sorry, I'm still not clear on something. Is your C# method being run? You can either add a Debug.Log() line inside your C# method or set a breakpoint and see if the debugger stops there.

Can you paste your C# method and the Lua.RegisterFunction() line into a reply?

If your C# method is not being run, temporarily set the Dialogue Manager's Debug Level to Info. When you play the scene, look for a Console message like this:

Dialogue System: Registering Lua function (your C# method here)

That will let you know that it's properly registered. Also make sure the name matches exactly with what's in your dialogue entry node's Script field, including capitalization.
