Script Errors

script_error(string message, [number stack level modifier], [boolean suppress assert])

Throws a script error with the supplied message, printing the lua callstack to the Lua console output spool. Useful for debugging.

Parameters:

1

string

Message to print.

2

number

optional, default value=0

By default this function will print the callstack of the calling function. A modifier may be supplied here to alter which function in the callstack should be at the top of the callstack. A positive integer moves the callstack pointer down the callstack, so a supplied value of 1 here would mean the callstack of the function calling the function calling script_error would be printed.

If the stack level modifier is set to a negative number then no traceback is printed as part of the script error. This can be useful if the error message itself contains a traceback.

3

boolean

optional, default value=false

If set to true then no assert is generated with this script error.

Returns:

  1. nil

Output

out(string output)
out is a table that provides multiple methods for outputting text to the various available debug console spools. It may be called as a function to output a string to the main Lua console spool, but the following table elements within it may also be called to output to different output spools:
  • grudges

  • ui

  • chaos

  • traits

  • help_pages

  • interventions

  • invasions

  • design


    • out supplies four additional functions that can be used to show tab characters at the start of lines of output:
    FunctionDescription
    out.inc_tabIncrements the number of tab characters shown at the start of the line by one.
    out.dec_tabDecrements the number of tab characters shown at the start of the line by one. Decrementing below zero has no effect.
    out.cache_tabCaches the number of tab characters currently set to be shown at the start of the line.
    out.restore_tabRestores the number of tab characters shown at the start of the line to that previously cached.
    Tab levels are managed per output spool. To each of these functions a string argument can be supplied which sets the name of the output spool to apply the modification to. Supply no argument or a blank string to modify the tab level of the main output spool.

    Parameters:

    1

    string

    output

    Returns:

    1. nil

    Example - Standard output:

    out("Hello World")
    out.inc_tab()
    out("indented")
    out.dec_tab()
    out("no longer indented")
    Hello World
        indented
    no longer indented

    Example - UI tab:

    Output to the ui tab, with caching and restoring of tab levels
    out.ui("Hello UI tab")
    out.cache_tab("ui")
    out.inc_tab("ui")
    out.inc_tab("ui")
    out.inc_tab("ui")
    out.ui("very indented")
    out.restore_tab("ui")
    out.ui("not indented any more")
    Hello UI tab
                very indented

    set_class_custom_type(table class table, string custom type)

    Sets a supplied class table to the supplied type string by setting its __custom_type value. Once this is set, other object tables that are later set to derive from this class with set_object_class will report this custom type when passed to get_custom_type or is_custom_type.

    set_class_tostring(table class table, string custom type)

    Sets the tostring value of a supplied class table to the specified value by setting its __tostring value. Once this is set, other object tables that are later set to derive from this class with set_object_class will return this value when passed to tostring().
    The tostring specifier may be supplied as a string or a function. If supplied as a function, that function will be called when the tostring() function is called with an object derived from the supplied class. The object will be supplied as a single argument to the tostring specifier function, which allows the tostring() value to be assembled at runtime and include elements such as the objects name, co-ordinates or other realtime information. The specifier function should return a string.
    The default behaviour is for the generated string to be cached in the object table, at the __cached_tostring field. Further calls to tostring() will then return the cached string rather than regenerating it each time. If this is undesirable - for example if the generated string might change as the object changes state - then the do_not_cache flag may be set on this function.
    The flag to not append the memory address may be set if the memory address of the table is not wanted on the end of the returned tostring value. The default behaviour is to append the memory address.

    Parameters:

    1

    table

    class table

    2

    string

    custom type

    Returns:

    1. nil

    set_object_class(table object table, table class table, ... additional interfaces)

    Sets the supplied object to index from the supplied class in a manner that emulates object-orientation. This will set the class to be the metatable of the object and will set the __index field of the metatable also to the supplied class. This means that if functions or values are looked up on the object and are not present they are then looked up on the class. It is through this kind of mechanism that object-orientation may be emulated in lua. Because the class is also the metatable, it means the metatable is shared between objects of the same type. Use set_object_class_unique if this is not desired.
    set_object_class will also associate the object with any custom type or tostring values that have been previously set up on the class with calls to set_class_custom_type and set_class_tostring.
    Any number of additional classes and objects may be specified, from which the main supplied object will also derive. If a value (such as a function to be called) is looked up on the object and is not provided on the object or the main class table it derives from, it will be looked up in turn on each additional classes or objects supplied. These additional objects/classes may be table or userdata values.

    Parameters:

    1

    Object table.

    2

    Class table.

    3

    set_object_class_unique(table object table, table class table, ... additional interfaces)

    Sets the supplied object to index from the supplied class in a manner that emulates object-orientation. This will set up a metatable unique to this object and will set the __index field of this metatable to the supplied class. This means that if functions or values are looked up on the object and are not present they are then looked up on the class. It is through this kind of mechanism that object-orientation may be emulated in lua. In contrast to object-to-class relationships set up with set_object_class the metatable is not shared between objects of the same type, which is less memory-efficient but may be desirable in certain circumstances.
    set_object_class_unique will also associate the object with any custom type or tostring values that have been previously set up on the class with calls to set_class_custom_type and set_class_tostring.
    Any number of additional classes and objects may be specified, from which the main supplied object will also derive. If a value (such as a function to be called) is looked up on the object and is not provided on the object or the main class table it derives from, it will be looked up in turn on each additional classes or objects supplied. These additional objects/classes may be table or userdata values.

    set_class_metatable(table class table, table metatable, [boolean allow overwrite])

    Sets the metatable of the specified class table to the supplied table. This also sets the __is_class_definition field in the metatable which set_object_class uses internally to know the difference between a class definition (which has no concept of self) and an object definition (which does) in certain circumstances. This function is for use in specific situations where a class definition requires a metatable and objects derive from it.

If a uicomponent is found, its descendants are then searched for a uicomponent with the next name in the list, and so on until the list is finished or no uicomponent with the supplied name is found. A fragmentary path may be supplied if it still unambiguously specifies the intended uicomponent.

    Parameters:

    1

    uicomponent

    optional, default value=nil

    parent ui component

    2

    ...

    list of string names

    Returns:

    1. uicomponent child, or false if not found.

    find_uicomponent_from_table(
      uicomponent     parent ui component,
      table     table of string names,
      [assert     on failure]
    )
    Takes a start uicomponent and a numerically-indexed table of string uicomponent names. Starting from the supplied start uicomponent, the function searches through all descendants for a uicomponent with the next supplied uicomponent name in the table. If a uicomponent is found, its descendants are then searched for a uicomponent with the next name in the list, and so on until the list is finished or no uicomponent with the supplied name is found. This allows a uicomponent to be searched for by matching its name and part of or all of its path.

    Parameters:

    1

    uicomponent

    Parent uicomponent.

    2

    table

    Table of string names, indexed by number.

    3

    assert

    optional, default value=false

    Fire a script error if the search fails.

    Returns:

    1. uicomponent child, or false if not found.

      boolean     should pulse,
      [number     brightness],
      [boolean     progagate],
      [string     state name]
    )
    Activates or deactivates a pulsing highlight effect on a particular state of the supplied uicomponent. This is primarily used for scripts which activate when the player moves the mouse cursor over certain words in the help pages, to indicate to the player what UI feature is being talked about on the page.

    Parameters:

    1

    uicomponent

    Subject ui component.

    2

    boolean

    Set to true to activate the pulsing effect, false to deactivate it.

    3

    number

    optional, default value=0

    Pulse brightness. Set a higher number for a more pronounced pulsing effect.

    4

    boolean

    optional, default value=false

    Propagate the effect through the component's children. Use this with care, as the visual effect can stack and often it's better to activate the effect on specific uicomponents instead of activating this.

    5

    string

    optional, default value=nil

    Optional state name to affect. If no string state name is supplied here then the current state is used.
