1 小怪软碰撞

新建一个Area2D节点softCollsion，挂载脚本soft_collsion.gd,添加碰撞形状

extends Area2D

func is_colliding():

	#1.判断是否重叠区域
	var areas = get_overlapping_areas()
	return areas.size() > 0
	
func get_push_vector():

	#定义重叠区域 和 软碰撞移动方向
	var areas = get_overlapping_areas()
	var push_vector=Vector2.ZERO
	
	#如果重叠
	if is_colliding():
		var area = areas[0]
		
		#移动方向
		push_vector =area.global_position.direction_to(global_position)
		push_vector = push_vector.normalized()
	return push_vector
