怎么做那种敌人在特定视野内看到主角就追逐的效果啊

空白文档TXT

想做个类似以前那种只要看到主角就会冒感叹号然后追逐主人公的效果，踩地雷的模式还是太难绷了

"Proximity Sensor 1.3"
当有事件发生时，该插件会激活一个开关/自开关，以便
玩家。这对漫游敌人、隐身序列和陷阱非常有用。
还可选择方向和视线。

更新
-V1.1 添加了 "面对一条线 "功能
-V1.2 开关现在可以切换；兼容性得到改善
-V1.3 修正了与某些像素移动脚本一起使用时的崩溃问题
____________________________________________________________________________
配置
1. 打开事件命令窗口，选择 "插件命令

2. 选择要使用的接近类型：
"所有方向"- 检查所有方向。
"面向"- 仅检查事件面向的方向。
"Orthogonal Directions（正交方向）"- 仅在十字形中进行检查。
面向一条直线"--"面向 "和 "正交 "的组合。

3. 设置操作员和距离，以确定事件的视距
（例如，如果玩家距离小于 3 个方砖，则检查 "小于 3"） 4.

4. 4. 设置开关和/或自开关，以便在事件接近时切换。

5. 在地图编辑器中设置区域 ID 和/或地形标签来表示障碍物。
