你最有可能想要移动CharacterBody2D本身，而不是Sprite2D。要做到这一点，最好的方式可能是在物理过程循环中。

func _physics_process(delta):
    move_and_collide(direction * strength * delta)

英文:

You'll most likely want to move the CharacterBody2D itself, not the Sprite2D. To do this, the best way is probably in the physics process loop.

func _physics_process(delta):
move_and_collide(direction * strength * delta)
