## 条件显示节点
|
||
|
||
### 特点
|
||
* 用于在游戏中显示或隐藏特定UI元素。
|
||
* 一般用于红点提示
|
||
* 主要是解耦用，条件单独实现，节点关联单条件或者多个条件
|
||
|
||
|
||
|
||
### 使用
|
||
|
||
#### *定义条件*
|
||
|
||
```typescript
|
||
// 定义条件类型枚举
|
||
enum ConditionType {
|
||
condition1,
|
||
condition2,
|
||
condition3,
|
||
}
|
||
|
||
// 定义条件
|
||
@conditionClass(ConditionType.condition1)
|
||
export class Condition1 extends kunpo.ConditionBase {
|
||
protected onInit(): void {
|
||
// 监听条件发生变化, 则调用一次 this.tryUpdate();
|
||
kunpo.GlobalEvent.add("condition1", () => {
|
||
this.tryUpdate();
|
||
}, this);
|
||
}
|
||
|
||
protected evaluate(): boolean {
|
||
//TODO:: 根据条件数据，返回true or false
|
||
return true;
|
||
}
|
||
}
|
||
```
|
||
|
||
#### *节点关联条件*
|
||
|
||
```typescript
|
||
/** 任意一个满足 显示节点 */
|
||
new kunpo.ConditionAnyNode(fgui.GObject, ConditionType.condition1, ConditionType.condition2);
|
||
|
||
/** 所有条件都满足 显示节点 */
|
||
new kunpo.ConditionAllNode(fgui.GObject, ConditionType.Condition1, ConditionType.Condition2, ConditionType.Condition3);
|
||
``` |
