A captured backtrace of a specific script language.
|

</brief_description>
|
|
<description>
|
|
[ScriptBacktrace] holds an already captured backtrace of a specific script language, such as GDScript or C#, which are captured using [method Engine.capture_script_backtraces].
|
|
See [member ProjectSettings.debug/settings/gdscript/always_track_call_stacks] and [member ProjectSettings.debug/settings/gdscript/always_track_local_variables] for ways of controlling the contents of this class.

<method name="format" qualifiers="const">
|
|
<return type="String" />
|

<param index="0" name="indent_all" type="int" default="0" />
|
|
<param index="1" name="indent_frames" type="int" default="4" />
|
|
<description>
|
|
Converts the backtrace to a [String], where the entire string will be indented by [param indent_all] number of spaces, and the individual stack frames will be additionally indented by [param indent_frames] number of spaces.
|
|
[b]Note:[/b] Calling [method Object.to_string] on a [ScriptBacktrace] will produce the same output as calling [method format] with all parameters left at their default values.

<method name="get_global_variable_count" qualifiers="const">
|
|
<return type="int" />
|
|
<description>
|
|
Returns the number of global variables (e.g. autoload singletons) in the backtrace.
|
|
[b]Note:[/b] This will be non-zero only if the [code]include_variables[/code] parameter was [code]true[/code] when capturing the backtrace with [method Engine.capture_script_backtraces].

<return type="Variant" />
|
|
<param index="0" name="variable_index" type="int" />
|
|
<description>
|
|
Returns the value of the global variable at the specified index.
|
|
[b]Warning:[/b] With GDScript backtraces, the returned [Variant] will be the variable's actual value, including any object references. This means that storing the returned [Variant] will prevent any such object from being deallocated, so it's generally recommended not to do so.
