Godot 3.2.3
Not much to say, just go to the code. Below is the code of a halo effect node of the game I am doing
class_name HaloList extends Node
"""面板属性"""
var halo_num: int = 1 setget set_halo_num # 光环数量
"""私有变量"""
var property_data: Dictionary = {
} # 记录属性的数据
var property_list = []
##==============================
## setget方法
##==============================
func set_halo_num(value) -> void:
halo_num = max(0, value)
property_list_changed_notify() # 发出通知更新属性面板
##==============================
## 内置方法

func _get_property_list() -> Array:
var group_name: String
property_list = [
{
name='HaloProperty', type=TYPE_NIL, usage=PROPERTY_USAGE_CATEGORY | PROPERTY_USAGE_SCRIPT_VARIABLE},
{

]
# 动态添加属性
for i in range(halo_num):
group_name = 'halo' + str(i) + '/'
property_list.append({
name=group_name + 'color', type=TYPE_COLOR})

return true
OK, done.
