Question

`I want to give my player some walking animations that end when the player stops moving, but when I put an if statement inside the func _process(delta stuff), it gives me an Assignment is not allowed inside an expression error. Here’s the code for context:

@onready var Cuc_Sprite: Sprite2D = $Sprite2D
@onready var cuc_anims: AnimationPlayer = $Sprite2D/Cuc_Anims


var Speed = 250.0 #Speed
const Accelerant = 5.0 #Acceleration

var input: Vector2

func get_input():
	input.x = Input.get_action_strength("Right") - Input.get_action_strength("Left") #Detects Left and Right inputs
	input.y = Input.get_action_strength("Down") - Input.get_action_strength("Up") #Detects Down and Up inputs
	return input.normalized() #Makes so you don't go Sonic speed if you press both X and Y inputs


func _process(delta: float) -> void:
	var PlayerInput = get_input()
	
	velocity = lerp(velocity, PlayerInput * Speed, delta * Accelerant) #Makes you walk and it's smooth (Accelerant value is for the smoothing lol)
	
	move_and_slide() #Makes you shmove
	
	#I put the if statement here
	
	if Input.is_action_pressed("Left"):
		Cuc_Sprite.flip_h = true
	elif Input.is_action_pressed("Right"):
		Cuc_Sprite.flip_h = false
	else:
		pass```

“Assignment is not allowed inside an expression” usually means that you tried to use the = operator inside an if statement, if Input.x = 0: throws this error for example. if Input.x == 0 would be the correct version in this example.

Yeah, that was the issue, a simple rookie mistake
