We don't use that info for anything, and it generates unnecessary diffs every time we bump the minor version (and CI failures if we forget to sync some files from opt-in modules (mono, text_server_fb).

A [bool] is always one of two values: [code]true[/code] or [code]false[/code], similar to a switch that is either on or off. Booleans are used in programming for logic in condition statements.
|
|
Booleans can be directly used in [code]if[/code] and [code]elif[/code] statements. You don't need to add [code]== true[/code] or [code]== false[/code]:
|
|
[codeblocks]
|
|
[gdscript]
|
|
if can_shoot:
|
|
launch_bullet()
|
|
[/gdscript]
|
|
[csharp]
|
|
if (canShoot)
|
|
{
|
|
launchBullet();
|
|
}
|
|
[/csharp]
|
|
[/codeblocks]
|
|
Many common methods and operations return [bool]s, for example, [code]shooting_cooldown <= 0.0[/code] may evaluate to [code]true[/code] or [code]false[/code] depending on the number's value.
|
|
[bool]s are usually used with the logical operators [code]and[/code], [code]or[/code], and [code]not[/code] to create complex conditions:
|
|
[codeblocks]
|
|
[gdscript]
|
|
if bullets > 0 and not is_reloading:
|
|
launch_bullet()
|
|
|
|
if bullets == 0 or is_reloading:
|
|
play_clack_sound()
|
|
[/gdscript]
|
|
[csharp]
|
|
if (bullets > 0 && !isReloading)
|
|
{
|
|
launchBullet();
|
|
}
|
|
|
|
if (bullets == 0 || isReloading)
|
|
{
|
|
playClackSound();
|
|
}
|
|
[/csharp]
