Lua 魔兽世界API设置点API“；不能'；找不到名为'的区域；（空）和#x27&引用；

我想修复TukUI插件中的lua错误

GameTooltip:SetPoint（）：找不到名为“（null）”的区域

。当我的两个插件打开时就会发生这种情况：TukUI（moded）和LKNOWNER。如果我关闭LKNOWNER，错误就会消失。我读到你不能简单地在WoW中调试lua代码，因为你可能在附加调试器时被禁止。我唯一能想到的就是使用

print

调用。这有点奇怪，但如果我重新加载UI（/reload），错误消息就会消失。它可能与插件加载顺序有关吗

我的目标是自己找出问题并解决它。我在这里发现API：

插件的链接：（3.3.5）

打印结果：

print(self) // nil
print(TukuiDB) // table: 1BDD81D0

这是错误消息：

我也读了这篇文章：我尝试了BugSack和BugGrabber来识别问题。它说：

问题：GameTooltip:SetPoint（）自WoW 8.2以来受到保护，以防止作弊

详细信息：此加载项试图通过手动将锚重新定位到其他位置来覆盖GameTooltip:SetOwner（）的行为，该行为仅出现在前面的两行。它通过清除所有点（第93行）和手动分配点（第94行）来实现

假设：设定点命令最初在WoW 8.2之前正确执行，这意味着TukuiDB.mult是工具提示的数字y偏移

解决方案：用一个命令替换第92到94行

GameTooltip:SetOwner(self, "ANCHOR_TOP", 0, TukuiDB.mult)

你是这个意思吗？它给出了一个新错误：

Message:Interface\AddOns\Tukui\datatext\system.lua:98:尝试索引全局“TukUIDB”（一个零值）

。另外，补丁版本是3.3.5。我犯了一个错误，修复了上面的问题。TukUIDB应该是TukUIDB。另外，这是SetOwner（）。我在WowMedia上链接了正确的命令，但不小心在答案中写错了。英雄联盟

GameTooltip:SetOwner(self, "ANCHOR_TOP", 0, TukuiDB.mult)
