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 && 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.
