<param index="1" name="message" type="String" default="""" />
|
|
<description>
|
|
Asserts that the [param condition] is [code]true[/code]. If the [param condition] is [code]false[/code], an error is generated. When running from the editor, the running project will also be paused until you resume it. This can be used as a stronger form of [method @GlobalScope.push_error] for reporting errors to project developers or add-on users.
|
|
An optional [param message] can be shown in addition to the generic "Assertion failed" message. You can use this to provide additional details about why the assertion failed.
|
|
[b]Warning:[/b] For performance reasons, the code inside [method assert] is only executed in debug builds or when running the project from the editor. Don't include code that has side effects in an [method assert] call. Otherwise, the project will behave differently when exported in release mode.
|

# Imagine we always want speed to be between 0 and 20.
|
|
var speed = -10
|
|
assert(speed < 20) # True, the program will continue
|
|
assert(speed >= 0) # False, the program will stop
|
|
assert(speed >= 0 and speed < 20) # You can also combine the two conditional statements in one check
|
|
assert(speed < 20, "the speed limit is 20") # Show a message

|
|
[/codeblock]
|
|
[b]Note:[/b] This function only works if the running instance is connected to a debugging server (i.e. an editor instance). [method get_stack] will not work in projects exported in release mode, or in projects exported in debug mode if not connected to a debugging server.
|
|
[b]Note:[/b] Calling this function from a [Thread] is not supported. Doing so will return an empty array.

<param index="0" name="var" type="Variant" />
|
|
<description>
|
|
Returns the length of the given Variant [param var]. The length can be the character count of a [String], the element count of any array type or the size of a [Dictionary]. For every other Variant type, a run-time error is generated and execution is stopped.
|
|
[codeblock]

|
|
<method name="load">
|
|
<return type="Resource" />
|
|
<param index="0" name="path" type="String" />
|
|
<description>
|
|
Returns a [Resource] from the filesystem located at the absolute [param path]. Unless it's already referenced elsewhere (such as in another script or in the scene), the resource is loaded from disk on function call, which might cause a slight delay, especially when loading large scenes. To avoid unnecessary delays when loading something multiple times, either store the resource in a variable or use [method preload].
|
|
[b]Note:[/b] Resource paths can be obtained by right-clicking on a resource in the FileSystem dock and choosing "Copy Path" or by dragging the file from the FileSystem dock into the script.
|
|
[codeblock]
|
|
# Load a scene called "main" located in the root of the project directory and cache it in a variable.
|
|
var main = load("res://main.tscn") # main will contain a PackedScene resource.
|
|
[/codeblock]
|
|
[b]Important:[/b] The path must be absolute. A relative path will always return [code]null[/code].
|
|
This function is a simplified version of [method ResourceLoader.load], which can be used for more advanced scenarios.
|
|
[b]Note:[/b] Files have to be imported into the engine first to load them using this function. If you want to load [Image]s at run-time, you may use [method Image.load]. If you want to import audio files, you can use the snippet described in [member AudioStreamMP3.data].
|

</description>
|
|
</method>
|
|
<method name="preload">
|
|
<return type="Resource" />
|
|
<param index="0" name="path" type="String" />
|
|
<description>
|
|
Returns a [Resource] from the filesystem located at [param path]. During run-time, the resource is loaded when the script is being parsed. This function effectively acts as a reference to that resource. Note that this function requires [param path] to be a constant [String]. If you want to load a resource from a dynamic/variable path, use [method load].
|
|
[b]Note:[/b] Resource paths can be obtained by right clicking on a resource in the Assets Panel and choosing "Copy Path" or by dragging the file from the FileSystem dock into the script.
|
|
[codeblock]
|
|
# Create instance of a scene.
|
|
var diamond = preload("res://diamond.tscn").instantiate()

<return type="void" />
|
|
<description>
|
|
Like [method @GlobalScope.print], but includes the current stack frame when running with the debugger turned on.
|
|
The output in the console may look like the following:
|
|
[codeblock]
|
|
Test print
|
|
At: res://test.gd:15:_process()
|
|
[/codeblock]
|
|
[b]Note:[/b] Calling this function from a [Thread] is not supported. Doing so will instead print the thread ID.
|

</description>
|
|
</method>
|
|
<method name="print_stack">
|
|
<return type="void" />
|
|
<description>
|
|
Prints a stack trace at the current code location. See also [method get_stack].
|
|
The output in the console may look like the following:
|
|
[codeblock]
|
|
Frame 0 - res://test.gd:16 in function '_process'
|
|
[/codeblock]
|
|
[b]Note:[/b] This function only works if the running instance is connected to a debugging server (i.e. an editor instance). [method print_stack] will not work in projects exported in release mode, or in projects exported in debug mode if not connected to a debugging server.
|
|
[b]Note:[/b] Calling this function from a [Thread] is not supported. Doing so will instead print the thread ID.

|
|
</method>
|
|
<method name="range" qualifiers="vararg">
|
|
<return type="Array" />
|
|
<description>
|
|
Returns an array with the given range. [method range] can be called in three ways:
|
|
[code]range(n: int)[/code]: Starts from 0, increases by steps of 1, and stops [i]before[/i] [code]n[/code]. The argument [code]n[/code] is [b]exclusive[/b].
|
|
[code]range(b: int, n: int)[/code]: Starts from [code]b[/code], increases by steps of 1, and stops [i]before[/i] [code]n[/code]. The arguments [code]b[/code] and [code]n[/code] are [b]inclusive[/b] and [b]exclusive[/b], respectively.
|
|
[code]range(b: int, n: int, s: int)[/code]: Starts from [code]b[/code], increases/decreases by steps of [code]s[/code], and stops [i]before[/i] [code]n[/code]. The arguments [code]b[/code] and [code]n[/code] are [b]inclusive[/b] and [b]exclusive[/b], respectively. The argument [code]s[/code] [b]can[/b] be negative, but not [code]0[/code]. If [code]s[/code] is [code]0[/code], an error message is printed.
|
|
[method range] converts all arguments to [int] before processing.
|
|
[b]Note:[/b] Returns an empty array if no value meets the value constraint (e.g. [code]range(2, 5, -1)[/code] or [code]range(5, 5, 1)[/code]).
|
|
Examples:
|
|
[codeblock]
|
|
print(range(4)) # Prints [0, 1, 2, 3]
|
|
print(range(2, 5)) # Prints [2, 3, 4]
|
|
print(range(0, 6, 2)) # Prints [0, 2, 4]
|
|
print(range(4, 1, -1)) # Prints [4, 3, 2]
|
|
[/codeblock]
|
|
To iterate over an [Array] backwards, use:
|
|
[codeblock]
|
|
var array = [3, 6, 9]
|
|
for i in range(array.size(), 0, -1):
|
|
print(array[i - 1])
|
|
[/codeblock]
|
|
Output:
|
|
[codeblock]
|
|
9
|
|
6
|
|
3
|
|
[/codeblock]
|
|
To iterate over [float], convert them in the loop.
|
|
[codeblock]
|
|
for i in range (3, 0, -1):
|
|
print(i / 10.0)
|
|
[/codeblock]
|
|
Output:
|
|
[codeblock]
|
|
0.3
|
|
0.2
|
|
0.1
|
|
[/codeblock]

|
<constant name="PI" value="3.14159265358979">
|
|
Constant that represents how many times the diameter of a circle fits around its perimeter. This is equivalent to [code]TAU / 2[/code], or 180 degrees in rotations.
|
|
</constant>
|
|
<constant name="TAU" value="6.28318530717959">
|
|
The circle constant, the circumference of the unit circle in radians. This is equivalent to [code]PI * 2[/code], or 360 degrees in rotations.
|
|
</constant>
|
|
<constant name="INF" value="inf">
|
|
Positive floating-point infinity. This is the result of floating-point division when the divisor is [code]0.0[/code]. For negative infinity, use [code]-INF[/code]. Dividing by [code]-0.0[/code] will result in negative infinity if the numerator is positive, so dividing by [code]0.0[/code] is not the same as dividing by [code]-0.0[/code] (despite [code]0.0 == -0.0[/code] returning [code]true[/code]).
|
|
[b]Warning:[/b] Numeric infinity is only a concept with floating-point numbers, and has no equivalent for integers. Dividing an integer number by [code]0[/code] will not result in [constant INF] and will result in a run-time error instead.
|
|
</constant>
|
|
<constant name="NAN" value="nan">
|
|
"Not a Number", an invalid floating-point value. [constant NAN] has special properties, including that it is not equal to itself ([code]NAN == NAN[/code] returns [code]false[/code]). It is output by some invalid operations, such as dividing floating-point [code]0.0[/code] by [code]0.0[/code].
|
|
[b]Warning:[/b] "Not a Number" is only a concept with floating-point numbers, and has no equivalent for integers. Dividing an integer [code]0[/code] by [code]0[/code] will not result in [constant NAN] and will result in a run-time error instead.

Define a new group for the following exported properties. This helps to organize properties in the Inspector dock. Groups can be added with an optional [param prefix], which would make group to only consider properties that have this prefix. The grouping will break on the first property that doesn't have a prefix. The prefix is also removed from the property's name in the Inspector dock.
|
|
If no [param prefix] is provided, the every following property is added to the group. The group ends when then next group or category is defined. You can also force end a group by using this annotation with empty strings for parameters, [code]@export_group("", "")[/code].
|
|
Groups cannot be nested, use [annotation @export_subgroup] to add subgroups within groups.

Export an [int] or [float] property as a range value. The range must be defined by [param min] and [param max], as well as an optional [param step] and a variety of extra hints. The [param step] defaults to [code]1[/code] for integer properties. For floating-point numbers this value depends on your [code]EditorSettings.interface/inspector/default_float_step[/code] setting.
|
|
If hints [code]"or_greater"[/code] and [code]"or_less"[/code] are provided, the editor widget will not cap the value at range boundaries. The [code]"exp"[/code] hint will make the edited values on range to change exponentially. The [code]"hide_slider"[/code] hint will hide the slider element of the editor widget.
|
|
Hints also allow to indicate the units for the edited value. Using [code]"radians"[/code] you can specify that the actual value is in radians, but should be displayed in degrees in the Inspector dock. [code]"degrees"[/code] allows to add a degree sign as a unit suffix. Finally, a custom suffix can be provided using [code]"suffix:unit"[/code], where "unit" can be any string.
