GIANTS Debugger/Studio

The GIANTS Studio is a new tool for creating, editing and debugging script mods. It works as an editor and a “remote” debugger in one. It interacts with the game state and provides you with information about the game state.

Possible use-case scenarios:

• to create or modify Lua and XML files
• using breakpoints to see how script is executed
• investigating a paused game state by looking through callstack or inspecting variables
• seeing when and how variables change
• live-coding by writing script while the game is running

The Debugger can be used on all kinds of mod configurations. These are the most common three configurations:

Working on a single mod (fast iteration time, but only compatible with singeplayer):
Unzip your mod and put the mod in the “mods” directory (by default in Documents/My Games/FarmingSimulator2019/mods). Make sure that the layout of the mod is correct, i.e. the modDesc.xml is directly in the mod folder (i.e. mods//modDesc.xml). Then create a new project in the Debugger. In “Project Settings”, set “Mod Name” to be the same name as the name of the mod folder and set the “Mod Directory” as a path to the directory of the mod (mods/). In case the mod zip file is already in the “mods” directory remove the zip file from the “mods” directory, because the zip file has priority over the directory when the game is loading.

Working on multiple mods at the same time (fast iteration time, but only compatible with singeplayer):
Follow the instructions above, but when you create a project in the Debugger, set the “Mod Directory” to “mods” directory instead of the specific mod directory. This way you can edit several mods at the same time. In this configuration, the “Mod Name” is not important, you can call it anything you like.

Working on a single mod outside the “mods” directory (also compatible with multiplayer):
This is the most complex configuration, and it is the only one that lets you debug mods in multiplayer. Place the mod zip file in the “mods” directory and unzip it somewhere else. In “Project Settings” set the “Mod Name” to match with the name of the zip file but without .zip at the end) and set the “Mod Directory” as a path to the unzipped directory. For every change you make in the Debugger, you will have to re-create the mod zip file and copy it to the “mods” directory before you start the game. External tools for zipping are useful for this purpose (not included).

Overview of panels

• File Browser: view files and folders in your project directory
• Functions: list of functions defined in the current file
• Globals: view global variables
• Locals: view local variables
• Watch: view the values of user-defined variables
• Script console: run user-defined parts of code
• Callstack: view current callstack
• Breakpoints: manage breakpoints
• Output: view log output
• Find Results: view results from the Find in Files dialog

Creating a new project

First you need to open or create a project.

Most of the required parameters are self-explanatory. The “Mod Directory” can be a path to a single mod or a “mods” directory if you are working on several mods at the same time. If you are working on a single mod, the “Mod Name” must have the same name as the .zip file. The “User Profile App Directory” should be saved as a path to a folder where the game stores user data (changes are not needed by default if the game configuration has not been changed manually). The debugger uses sockets to communicate with the game and listens at the port defined as the “Debug Network Port”.

Global and local variables

The function of the “Globals” and “Locals” panels is the same: to explore the value of local and global variables at a current execution point (using breakpoints to halt execution and observe these variables, or by hitting the ‘break all’ button). By right-clicking on a variable, you can add it as a “Watch” or a “Breakpoint”.

The ”Watch” panel is similar to the “Globals” and “Locals” panel, but instead of global or local variables, you can select variables that you would like to ‘watch’. Values are updated every time a breakpoint is hit or when you execute the code step-by-step. Variable names can be written like most other simple Lua statements:

• variableName
• object.member
• table[1]
• table[index]
• table[object.index]

Callstack panel

The “Callstack” panel shows you the callstack at a current execution point. Double-click on a line to open a file at the location of the call. The Debugger even allows you to step through some of the base game functions for which the source code has been made public. Grayed-out lines are parts of code that have not been made public.

Running new scripts during debugging

The “Script Console” executes user-defined Lua code when execution is paused (by hitting a breakpoint or break-all being pressed). Enter your code in the bottom part of the panel and press Ctrl + Enter to execute it.

Breakpoints

The “Breakpoints” panel is where you manage breakpoints.

Regular breakpoints can be placed in the code by clicking on the vertical gray bar on the left of the code panel. You can also use F9 to enable/disable a breakpoint at the current position. The program will stop running when it tries to execute a line with a breakpoint.

Data breakpoints can be placed by right-clicking on a variable name in the “Globals”/”Locals”/”Watch” panel or by right-clicking on a name in the text editor. A data breakpoint will be hit when the data for the specified variable changes.

You can fine-tune a breakpoint by adding a conditional expression and/or hit count condition to it. These conditions are evaluated each time a breakpoint is hit and the code will only stop executing once the conditions are met.

Game output

The “Output” panel shows the game’s log output. If a script error is reported, this panel will provide you with the file name and line number, so that you can double-click on it and view the code causing the error. The output is the same as the log file written by the game.

Searching in code

The “Find Results” panel shows search results from the “Find in Files” dialog. Double-clicking on a result opens a file at the search hit location.

The “Find Replace” window behaves in a similar way to other text editors. “Find” and “Replace” directly show the results in the text editor; while “Find in Files” searches through the entire file and shows results in the “Find Results” panel. Other search modes are available too:

• “Extended” search allows you to use special “escape” characters (\t = tab, \n = new line, \r = carriage return, \0 NULL character and \\ = backslash)
• “Regular Expression” searches with regular expressions. Captures are defined with brackets ‘(‘ and ‘)' in the search string and can be placed with $1-$9 in the replace string.

FocusManager

Description

The FocusManager controls which element in the menu system is currently focused
and allows menu control with only keyboard or gamepad.
For each participating gui element the focus state and the next focused gui element
in each direction is stored. This data is set up directly in the xml file of the gui screen
and loaded through the loadElementFromXML() function or manually loaded within code by using
the loadElementFromCustomValues() method.
Focus handling is independent for every screen in the GUI. To swap screens the setGui() method
has to be used.
The focus system is then controlled with 5 actions: MENU_UP, MENU_DOWN, MENU_RIGHT and MENU_LEFT to
change the currently focused element in the specified direction and MENU_ACCEPT to activate
the currently focused element.
-- When using dynamically changing objects which cannot be set directly in the XML file of the screen
the method createLinkageSystemForElements() can be used to set up direction links between the
passed elements automatically.

Add an element to the focus system with custom values.
The caller should ensure that explicitly set focus IDs are unique. If a duplicate ID is encountered, only the first
element with that focus ID is considered for focusing. The method returns a boolean value to indicate any problems
with data assignment. Callers can evaluate the value to check if the given parameters were valid. If in doubt or
when no elaborate focus navigation is needed, rely on automatic focus ID generation by omitting the ID parameter
(or set it to nil).

loadElementFromCustomValues(element Element, focusId Focus, focusChangeData Custom, focusActive If, isAlwaysFocusedOnOpen If)

removeElement

FrameElement

Description

Base display frame element. All GUI views (partial and full screen) inherit from this.
-- This element provides the functionality to register control IDs, which are then exposed as fields of the concrete
descendant class (e.g. MainScreen or PasswordDialog). The control IDs must be assigned verbatim to any control
in the corresponding configuration XML file. If a registered ID is not used, the field will not be assigned and
access will fail. Available field IDs are documented as field properties per class. When creating a new view, take

and that IDs are also valid as identifiers in Lua. If a control has been registered but no corresponding element is
available (e.g. when sub-classing and omitting some elements), the field will remain undefined. It's up to callers
to ensure that field configuration and usage in views matches.

GuiElement

Description

GUI Element base class.
All elements displayed in the game UI must be instances or descendants of this class.
-- All XML configuration properties as declared below (and in subclasses) are mirrored in guiProfiles.xml as key-value
pairs in the form of &ltValue name="property_name" value="value" /&gt. Profiles are able to inherit from other
profiles, so take care to check their hierarchy if any of your settings do not seem to have any effect. Directly set
properties in the XML configuration will always override profile values, however.
-- Layer properties, prefixed with "[layer]", interact with an overlay system and provide display images. Usable
layers, whose names are substituted for the prefix, are primarily "image" and "icon". UI elements define layer names
on their own and read them from these generated properties. Whenever an element requires a layer, it is described
in its documentation such as this one. Example for an icon layer focus color property:
iconFocusedColor="0.9 0.1 0.5 1.0".
-- A note regarding callbacks: All callbacks are called on an element's target first. When GUI elements are created from
configuration, their top-level view (e.g. MainScreen) is the callback target, i.e. MainScreen:callbackName() is
executed. Unless an element's target has been set to another value explicitly via code, this will always be the case.
--@category GUI
--@xmlConfig GuiElement#id string [optional] Element ID. Must be unique per GUI screen. If set on an element, will expose it as an indexable field on the view class (e.g. id="buttonOk" -> MainScreen.buttonOk). Use this feature sparingly, as it creates implicit coupling which leads to tedious debugging.

inputEvent

Handles an input event on a menu input action.
Input is first passed to the current GUI view, then to the focused element, then to the focus manager for navigation.
When a GUI element receives input, it should always propagate the input to its parent element first so they may
override behavior and/or set the event used flag. If properly inherited from GuiElement and descendants, this
behavior is guaranteed.

inputEvent(action Name, value Input, eventUsed If)

evaluated per element and only elements which yield a true value for the function are added to the accumulator.

findDescendantsRec(accumulator List, rootElement Current, predicateFunction [optional])

getDescendants

Get all contained elements of this element in the entire hierarchy.
Descendants are traversed depth-first, meaning that if elements have been properly added, the element order mirrors
the order in the XML configuration (lines). Use this method sparingly, especially on high-level elements.
Optionally, a predicate function can be passed which filters descendant elements. The function must return true for
any desired element and false otherwise.

getDescendants(predicateFunction [optional])

getFirstDescendant
