【12.创建 Task 节点 | Unreal Engine】

Quick Start Home


Task 是真正“执行”操作的节点，如移动 AI，或调整黑板值。它们可以被 Decorators 附着。

这里的这个 Task 实际上是 Move To 节点的新形态，主要的不同点是：Task 节点将指引 AI 向玩家的 Pawn 前进，而非向其所在位置前进。此外，它有助于分解任务，并确认如未执行 Finish Execute，Task 节点将继续进行处理，AI MoveTo 节点完整地展示了这点。
步骤
在 内容浏览器 中 双击 打开 FollowerBT 行为树。

点击 New Task 按钮。

它将创建于和行为树相同的文件夹中。

在 内容浏览器 中将其重命名为 “RapidMoveTo”。

编辑器应已将其打开以便编辑。如尚未打开，在 内容浏览器 中 双击 打开。

创建如下图表：
