[0.8.9][NK] Porting from 0.8.6

johnycilohokla · November 2015

NKGetInstance and .object

NKGetInstance is deprecated and scheduled for removal.
It used to retrieve the lua script instance associated with this GameObject, now this is done automatically.

Using this function will print console warnings (with stacktrace) to aid the removal.

Getting the native object is also deprecated, this used to be done using .object called on an instance of an object and was required when calling engine functions that required a game object (world queries, NKAddChildObject, ...)

Both NKGetInstance and .object and now automated by the engine and the lua versions return self to avoid crashes while porting.

Crafting recipes

Each recipe needs to define a craftingActionName and craftingDisplayName.

craftingActionName combined with craftingDisplayName is used the display the message on the progress bar.
craftingDisplayName is used as a name for the Crafting Journal.

Example:

	Recipe
	{
		...
		LuaData
		{
			craftingActionName = "Crafting... "
			craftingDisplayName = "Recipe"
			...
		}
	}

Registering new crafting recipe file now requires a 2nd parameter (category name):

Eternus.CraftingSystem:ParseRecipeFile( "path/to/file.txt", "CategoryName" )

Archetypes

The archetype system has changed in 0.8.7.

The new system is using txt files stored in Data/Archetypes/* to define groups of archetypes.

Example:

Archetypes
{
	Cobblestone Clump
	{
		Cobblestone
		Cobblestone Gray Clump
		Cobblestone Blue Clump
		Cobblestone Green Clump
	}
}

The deprecated system used to work by assigning craftingArchetype to an object in it's txt file.
This system is no longer in use.

World queries

World queries can now use a bitmask instead of just a layer ID.

Other notes

Invalid texture files parsed from txt files will now show an error during loading.

Texture atlas is no longer limited to 1024 icons.

VoxelsModifiedCallback will now get the userdata1, even when no player is specified.

You may not have mentioned that:
CraftingSystem:ParseRecipeFile( filePath, category )
now requires a category in its arguments

Charlock · December 2015

If your mod has a repair recipe file, does this also require and index?

If you have multiple files within the mod, does each recipe in each file require unique, sequential Index values?

Example:

File1 Recipes
{
	Recipe1
	{
		Index = 1
		...
	}

File2 Recipes
{
	Recipe1
	{
		Index = 2
		...
	}
	Recipe2
	{
		Index = 3
		...
	}

And so on..

The index is no longer required, we have removed the need for it with the last update.
Heh, I thought I have updated this tutorial... (fixed now)

Charlock · December 2015

Thanks for clarifying Johny. I just updated to the latest patch and I'm getting an error with my crafting mods enabled:

I see @UFIOES mentions a "category" attribute is now necessary in the ParseRecipeFile, which I don't have. Can you help me out with that?

Eternus.CraftingSystem:ParseRecipeFile("Data/Crafting/WhetstoneRecipe.txt")

Charlock · December 2015

Never mind this! I found it in your Crafting tutorial!

johnycilohokla · December 2015

Cool.
I have added the "category" to the Crafting Recipes section and links to the Crafting Recipes tutorial and Archetypes tutorial.

ekohrman · January 2016

Can I create my own category in the crafting journal or do I have to use an existing one?

johnycilohokla · January 2016

You can create new ones or add to existing ones.

Thanks!

Now if I could just get my crafting recipe to work. I cannot figure out what I'm doing wrong. I was able to add a new object which I can spawn, but the recipe just won't work.

Here is the lua for my mod, Terrella. Did I miss something here?


-------------------------------------------------------------------------------
if Terrella == nil then
	Terrella = EternusEngine.ModScriptClass.Subclass("Terrella")
end

-------------------------------------------------------------------------------
-- Called once from C++ at engine initialization time
function Terrella:Initialize()
    Eternus.CraftingSystem:ParseRecipeFile("Data/Crafting/TerrellaMod_recipes.txt", "Refined Resources")
end

EntityFramework:RegisterModScript(Terrella)

johnycilohokla · January 2016

Could you post the content of "Data/Crafting/TerrellaMod_recipes.txt"?
Also do you have console enabled? If you do, did you get any warnings?

ekohrman · January 2016

I didn't have the console turned on. I turned it on and all it said was that the debugger.lua loaded for Lua 5.1.

This is Data/Crafting/TerrellaMod_recipes.txt


All Recipes
{
Glow Corn Meal Recipe
{
Script = "Scripts/Recipes/DefaultRecipe.lua"
LuaData
{
craftingActionName = "Grinding... "
craftingDisplayName = "Glow Corn Meal"
#Craft times are below
unconsumedDamage = 3
priority = 1.0
Components
{

{
"Glow Corn" = 1
}
}
Crafting Tool
{
category = "Hammer"
tier = 1
}

{
"Glow Corn Meal" = 1
}
Crafting Stations
{
Flat Rock
{
offsetOverride = <0.0, 1.0, 0.0>
craftTime = 5.0
}
}
#Requirements to unlock this recipe in the crafting journal

#Player has collected one of these

{

{
name = "Glow Corn"
count = 1
}
}
}
}
}
}
}

Thanks, the crafting file works.

It might be that you are missing the Script definition in your Manifest.json

One way to check that would be to add an NKPrint or NKWarn in the Terrella:Initialize function.

NKWarn("Terrella:Initialize")

If it will not output to the console when you start the game you will need to add something like this to your Manifest.json:

	"Script":
	{
		"File": "Scripts/Terrella.lua",
		"Class": "Terrella"
	},

ekohrman · January 2016

I have this for my manifest.txt in my mod folder. Is that not correct?


Manifest
{
# Name of the mods.
Name = "Terrella"
# Description of the mod.
Description = "A test of the mod scripting system"
# The major version number.
MajorVersion = 0.8
# The minor version number.
MinorVersion = 0.9
#The file path to the script that is the entry point.
//ScriptFile = "Scripts/Terrella.lua"
#The script entry point class name
//ScriptClass = "Terrella"
}

NKPrint or NKWarn in the Terrella:Initialize function

Adding that to my lua didn't get me a notice in the console. So apparently it isn't initiating the script.

Charlock · January 2016

Did you mean to put "//" in front of your script paths? I don't think they will initialize properly with those there.

ekohrman · January 2016

D'oh! I knew it had to be something stupid simple that I missed. That worked perfectly. You guys rock so hard you set off seismometers! Thanks for helping an old lady out.

Charlock · January 2016

It's ALWAYS something simple! Just helps to get a second set of eyes.. or third, or fourth..
