A* (A star) is a computer algorithm that is widely used in pathfinding and graph traversal, the process of plotting short paths among vertices (points), passing through a given set of edges (segments). It enjoys widespread use due to its performance and accuracy. Godot's A* implementation uses points in three-dimensional space and Euclidean distances by default.
You must add points manually with [method add_point] and create segments manually with [method connect_points]. Then you can test if there is a path between two points with the [method are_points_connected] function, get a path containing indices by [method get_id_path], or one containing actual coordinates with [method get_point_path].
It is also possible to use non-Euclidean distances. To do so, create a class that extends [code]AStar[/code] and override methods [method _compute_cost] and [method _estimate_cost]. Both take two indices and return a length, as is shown in the following example.

[method _estimate_cost] should return a lower bound of the distance, i.e. [code]_estimate_cost(u, v) &lt;= _compute_cost(u, v)[/code]. This serves as a hint to the algorithm because the custom [code]_compute_cost[/code] might be computation-heavy. If this is not the case, make [method _estimate_cost] return the same value as [method _compute_cost] to provide the algorithm with the most accurate information.

Button is the standard themed button. It can contain text and an icon, and will display them according to the current [Theme].
[b]Example of creating a button and assigning an action when pressed by code:[/b]
[codeblock]
[codeblocks]
[gdscript]
func _ready():
var button = Button.new()
button.text = "Click me"
@ -15,7 +16,22 @@
func _button_pressed():
print("Hello world!")
[/codeblock]
[/gdscript]
[csharp]
public override void _Ready()
{
var button = new Button();
button.Text = "Click me";
button.Connect("pressed", this, nameof(ButtonPressed));
AddChild(button);
}
private void ButtonPressed()
{
GD.Print("Hello world!");
}
[/csharp]
[/codeblocks]
Buttons (like all Control nodes) can also be created in the editor, but some situations may require creating them from code.
See also [BaseButton] which contains common properties and methods associated with this node.

Boolean is a built-in type. There are two boolean values: [code]true[/code] and [code]false[/code]. You can think of it as an switch with on or off (1 or 0) setting. Booleans are used in programming for logic in condition statements, like [code]if[/code] statements.
Booleans can be directly used in [code]if[/code] statements. The code below demonstrates this on the [code]if can_shoot:[/code] line. You don't need to use [code]== true[/code], you only need [code]if can_shoot:[/code]. Similarly, use [code]if not can_shoot:[/code] rather than [code]== false[/code].
[codeblock]
var can_shoot = true
[codeblocks]
[gdscript]
var _can_shoot = true
func shoot():
if can_shoot:
if _can_shoot:
pass # Perform shooting actions here.
[/codeblock]
[/gdscript]
[csharp]
private bool _canShoot = true;
public void Shoot()
{
if (_canShoot)
{
// Perform shooting actions here.
}
}
[/csharp]
[/codeblocks]
The following code will only create a bullet if both conditions are met: action "shoot" is pressed and if [code]can_shoot[/code] is [code]true[/code].
[b]Note:[/b] [code]Input.is_action_pressed("shoot")[/code] is also a boolean that is [code]true[/code] when "shoot" is pressed and [code]false[/code] when "shoot" isn't pressed.
[codeblock]
var can_shoot = true
[codeblocks]
[gdscript]
var _can_shoot = true
func shoot():
if can_shoot and Input.is_action_pressed("shoot"):
if _can_shoot and Input.is_action_pressed("shoot"):
create_bullet()
[/codeblock]
[/gdscript]
[csharp]
private bool _canShoot = true;
public void Shoot()
{
if (_canShoot &amp;&amp; Input.IsActionPressed("shoot"))
{
CreateBullet();
}
}
[/csharp]
[/codeblocks]
The following code will set [code]can_shoot[/code] to [code]false[/code] and start a timer. This will prevent player from shooting until the timer runs out. Next [code]can_shoot[/code] will be set to [code]true[/code] again allowing player to shoot once again.
[codeblock]
var can_shoot = true
onready var cool_down = $CoolDownTimer

if _can_shoot and Input.is_action_pressed("shoot"):
create_bullet()
can_shoot = false
cool_down.start()
_can_shoot = false
_cool_down.start()
func _on_CoolDownTimer_timeout():
