Is it possible to change, or at least rename BaseStats and their descriptions? For example, rename Strength into Constitution, or remove resistance bonus from stats, or change their description, or add brand new stat to the game (so characters will have 5 or more stats)?

Good afternoon!
I'm trying to make an alternative ending for my mod and there was a question.
Is it possible to do so that, when entering the portal, the second video (the current where the heroes do not depart on the ship) starts to play?
And if you can, how exactly?

The Portal asset is defined with the ending video; you need to redefine the default asset, or define a new portal asset.

Code: Select all

defineObject{
	name = "portal",
	baseObject = "portal",
	components = {
		{
			class = "Portal",
			onArrival = function()
				--GameMode.completeGame("assets/videos/outro1.ivf")  --original
				GameMode.completeGame("mod_assets/videos/custom_ending_1.ivf")  --custom
			end,
		},
	},
}

You can make a slideshow video for the ending. You must encode the video with the VP8 codec.

Isaac, many thanks!

Loaded up one of my dungeons in the editor after about a year and upon activating a simple dig script the play tester crashes with the error shown in the linked image. It used to work perfectly fine. Nothing has changed except maybe steam updating LoG2 over the past year. Cannot figure out what is going on here. Given it is line 55 of the init.lua, I think it will happen any time 'onRest' is called up. Fairly certain I am using the latest GrimTK available on the Nexus as it hasn't been updated since 2015. https://steamuserimages-a.akamaihd.net/ ... 996C14DEC/

What is going on/How do I fix this?

*edit*
Can confirm simply resting will cause the crash as well, same thing:

mod_assets/ext/grimtk/init.lua:55: attempt to index field 'GUI' (a nil value)

segment containing called out line:

Code: Select all

if fw_hook == nil then

	defineObject{
		name = "party",
		baseObject = "party",
		components = {
			{
				class = "Party",
				onDrawGui = function(party, g)
					
				end,
				onRest = function(party)
					if ( findEntity("GTK") ) then
						if ( GTK.Core.GUI:isPartyLocked() ) then           <--- Line 55 (this comment obviously not in the code)
							return false;
						end
					end			
				end,
				onWakeUp = function(party)
					if ( findEntity("GTK") ) then
						if ( GTK.Core.GUI:isPartyLocked() ) then
							return false;
						end
					end
				end
			}
		}
	}

end

[akroma222]

the onRest (and onWakeUp) hooks will both crash it - but they work fine
the field GUI is coming up with nil, GUI is a huge table of custom functions within core.lua ,
("mod_assets/grimtk/scripts/gtk/core.lua")
Have you checked to make sure grimtk's init file is being imported from your mods init.lua ?
grimtk's init.lua defines the "grimtk" object, which is a script entity object that creates more script components - loading a bunch of .lua files

Code: Select all

defineObject{
	name = "grimtk",

double check that that is all still there and working

Have you checked to make sure grimtk's init file is being imported?

It would be hard for an error to occur in grimtk/init.lua if grimtk/init.lua wasn't being imported...

Definitely look at core.lua.

you're probably right, ya know!
Honestly, I think Ive rewritten that^^ message 7 times - and still missed that!
(its one of those days)

[gmsantashelper]

The core.lua does define GUI, and it is a lot of stuff. Not sure why it would be seen as nil if it has an abundance of values. What does it even mean by trying to index a nil value? I feel like this is turning out to not be a simple question, and needs more than just a simple answer, hah.

For sake of clarity, here is the entire grimtk init.lua, and yeah, it is definitely imported correctly, lol.

Code: Select all

defineObject{
	name = "grimtk",
	baseObject = "script_entity",
	components = {
		{
			class = "Null",
			onInit = function(self)
				if ( findEntity("GTK") == nil ) then
					local gtk = spawn("script_entity", 1, 1, 1, 1, 1, "GTK");
					gtk.script:loadFile("mod_assets/ext/grimtk/scripts/hook.lua");
					gtk:createComponent("Script", "Constants"):loadFile("mod_assets/ext/grimtk/scripts/gtk/constants.lua");
					gtk:createComponent("Script", "Input"):loadFile("mod_assets/ext/grimtk/scripts/gtk/input.lua");					
					gtk:createComponent("Script", "Core"):loadFile("mod_assets/ext/grimtk/scripts/gtk/core.lua");
					gtk:createComponent("Script", "Widgets"):loadFile("mod_assets/ext/grimtk/scripts/gtk/widgets.lua");

					if ( Editor.isRunning() ) then
						gtk:createComponent("Script", "Debug"):loadFile("mod_assets/ext/grimtk/scripts/gtk/debug.lua");
					end

					delayedCall("GTK", 0.01, "emitGtkDidLoad");
				end
				
				if ( findEntity("GTKGui") == nil ) then
					local gtkgui = spawn("script_entity", 1, 1, 1, 1, 1, "GTKGui");
					gtkgui:createComponent("Script", "Basic"):loadFile("mod_assets/ext/grimtk/scripts/gtkgui/basic.lua");
					gtkgui:createComponent("Script", "Dialogue"):loadFile("mod_assets/ext/grimtk/scripts/gtkgui/dialogue.lua");
					gtkgui:createComponent("Script", "Cinematic"):loadFile("mod_assets/ext/grimtk/scripts/gtkgui/cinematic.lua");					
				end
			end
		}
	}
}

-- If the Log2 Framework has been included before this script, then we will use the framework instead.
-- Otherwise, the default behaviour is to override these hooks.
-- NOTE: If you are using the framework, you MUST define an onDrawGui hook SOMEWHERE (even an empty one).

if fw_hook == nil then

	defineObject{

I'd simply pull out GrimTK but I planned to use it for dialogue popups to give hints/story elements without having to locate and read a note in places that don't really have that option. Honestly I don't remember what all uses it already, been so long.

[minmay]

It means you're trying to index nil. Indexing operators are ., :, and []. It is happening because GTK.Core.GUI is nil at the time that line executes.
This problem arises from a weakness in GrimTK, specifically in how it converts its source files to ScriptComponents. In certain contexts, after createComponent() returns, it's already too late to call loadFile(); the source you "load" won't actually load and run, because the ScriptComponent has already compiled. As a general rule, createComponent [...] loadFile will work at dungeon initialization time, but not afterwards. So if you're spawning the grimtk object dynamically instead of placing it in the dungeon editor, for example, you will probably run into this bug.

In short, place the grimtk object using the dungeon editor instead of trying to spawn it later.
