1 前言
本文将实现 cvs 表格数据与 UI Toolkit 元素的动态绑定。
如果读者对 UI Toolkit 不是太了解,可以参考以下内容。
本文完整资源见→UI Toolkit数据动态绑定。
2 数据动态绑定案例
2.1 UI 搭建
样式和 UI 层级结构如下。

显示效果如下。
2.2 创建模板
在 Hierarchy 窗口选中 RoleTemplate 元素,右键弹出菜单,选择 Create Template,选择 Resources 目录下保存 RoleTemplate.uxml,修改 Grow 为 1。

</ui:VisualElement>
</ui:VisualElement>
</ui:VisualElement>
</ui:UXML>
保存模板后,删除 Hierarchy 窗口中的 RoleTemplate 元素,后面会通过脚本加载 RoleTemplate。
2.3 自定义元素
RoleView.cs
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UIElements;
public class RoleView : VisualElement {
// 便于在UI Builder中导入自定义UI, 需要有无参构造函数
public new class UxmlFactory : UxmlFactory<RoleView> {}
private TemplateContainer container; // 模板容器
private List<VisualElement> properties; // 角色属性
public RoleView() {
container = Resources.Load<VisualTreeAsset>("RoleTemplate").Instantiate();
container.style.flexGrow = 1;
hierarchy.Add(container);
properties = container.Query("Property").ToList();
}
public RoleView(RoleData roleData) : this() {
userData = roleData;
UpdateRoleData();
container.RegisterCallback<MouseDownEvent>(OnClick);
}
private void OnClick(MouseDownEvent mouseDownEvent) { // 单击角色模板回调函数
RoleData roleData = (RoleData) userData;
if (mouseDownEvent.button == 0) { // 按下鼠标左键
roleData.RoleLevel++;
} else if (mouseDownEvent.button == 1) { // 按下鼠标右键
roleData.RoleLevel--;
}
UpdateRoleData();
}
private void UpdateRoleData() { // 更新角色数据
RoleData roleData = (RoleData) userData;
container.Q<VisualElement>("Image").style.backgroundImage = roleData.RoleImage;
container.Q<Label>("NameLab").text = roleData.RoleName;
SetProperty(properties[0], roleData.RoleLevel);
SetProperty(properties[1], roleData.LevelData.initiative);
SetProperty(properties[2], roleData.LevelData.maxHp);
SetProperty(properties[3], roleData.LevelData.maxMp);
SetProperty(properties[4], roleData.LevelData.attack);
SetProperty(properties[5], roleData.LevelData.defense);
}
private void SetProperty(VisualElement property, int value) { // 更新角色属性
property.Q<Label>("Value").text = value.ToString();
}
}
2.4 自定义数据
LevelData.cs
public class LevelData { // 等级属性数据
public int initiative; // 主动权(行动力/速度)
public int maxHp; // 最大生命值
public int maxMp; // 最大魔法值
public int attack; // 攻击力
public int defense; // 防御力
}
RoleData.cs
using System.Collections.Generic;
using UnityEngine;
[CreateAssetMenu(menuName = ("RoleData"), fileName = ("RoleData_"))]
public class RoleData : ScriptableObject { // 角色属性数据
private const int roleMaxLevel = 10; // 最大等级
[SerializeField]
private TextAsset levelDataFile; // 等级数据csv文件
[SerializeField]
private Texture2D roleImage; // 角色头像
[SerializeField]
private string roleName; // 角色名
[SerializeField, Range(1, roleMaxLevel)]
private int roleStartLevel = 1; // 角色开始等级
[SerializeField]
private List<LevelData> levelDatas; // 等级数据
private int roleLevel; // 角色当前等级
public Texture2D RoleImage => roleImage; // 获取角色头像
public string RoleName => roleName; // 获取角色名
public int RoleLevel { // 获取/设置角色等级
get => roleLevel;
set {
if (roleLevel == value || value < 1 || value > roleMaxLevel) {
return;
}
roleLevel = value;
}
}
public LevelData LevelData => levelDatas[roleLevel - 1]; // 获取角色等级数据
private void OnEnable() {
roleLevel = roleStartLevel;
}
private void OnValidate() {
if (levelDataFile == null) {
return;
}
if (levelDatas == null) {
levelDatas = new List<LevelData>();
}
levelDatas.Clear();
string[] textInLines = levelDataFile.text.Split('\n');
for (int i = 1; i < textInLines.Length; i++) {
string[] statsValues = textInLines[i].Split(",");
LevelData levelData = new LevelData();
levelData.initiative = int.Parse(statsValues[0]);
levelData.maxHp = int.Parse(statsValues[1]);
levelData.maxMp = int.Parse(statsValues[2]);
levelData.attack = int.Parse(statsValues[3]);
levelData.defense = int.Parse(statsValues[4]);
levelDatas.Add(levelData);
}
}
}
编译后,在 Assets 窗口右键,依次选择【Create→RoleData】,创建 4 个对象,对应 4 个角色的配置,分别重命名为 RoleData_1.asset、RoleData_2.asset、RoleData_3.asset、RoleData_4.asset。
选中 ScriptableObject 配置文件后,在 Inspector 窗口配置角色属性。
其中 LevelDataFile 是角色每个等级的属性 cvs 表,内容如下。
2.5 元素加载
RoleLoader.cs
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UIElements;
public class RoleLoader : MonoBehaviour {
[SerializeField]
private List<RoleData> roleDatas; // 角色数据
private VisualElement root; // 根容器
private void Awake() {
root = GetComponent<UIDocument>().rootVisualElement;
var bodyContainer = root.Q("Body");
bodyContainer.Clear();
for(int i = 0; i < roleDatas.Count; i++) {
RoleView roleView = new RoleView(roleDatas[i]);
roleView.style.flexBasis = Length.Percent(25.0f);
bodyContainer.Add(roleView);
}
}
}
说明:RoleLoader 脚本组件挂在 UIDocument 对象上,并且需要将 RoleData_1.asset、RoleData_2.asset、RoleData_3.asset、RoleData_4.asset 赋给 RoleDatas,如下。
2.6 运行效果
运行效果如下,单击卡片,角色的等级会升 1 级,等级属性也会按照 cvs 表格中的策略数据同步更新。
