Hi guys,
I’m reading the templates to learn gd4.

in template charactor body base movement, there is some code here:

var input_dir = Input.get_vector("ui_left", "ui_right", "ui_up", "ui_down")
var direction=(transform.basis * Vector3(input_dir.x, 0, input_dir.y)).normalized()
#var direction = Vector3(input_dir.x ,0,input_dir.y)
print(direction)
if direction:#my question here
	velocity.x = direction.x * SPEED
	velocity.z = direction.z * SPEED
else:
	velocity.x = move_toward(velocity.x, 0, SPEED)
	velocity.z = move_toward(velocity.z, 0, SPEED)

I’m so confusing:
In which condition, the “direction” will turn to FALSE, make the else block run?

That else block will execute when none of the 4 inputs are being pressed.
