dunno how to fix it but, theres a lot of mods with the same problem. I know at least that it has something to do with CastMORay. How Ray casting was handled by LUA had changed at some point and now you need an additional variable. Check the ingame lua console with tilda or / and you'll see a error spammed relating to that.

If you get lua errors porting other mods check the official DataRealms wiki, the notations there are really good.



TLDR: My best guess is that this part is wrong

self.parent = MovableMan:GetMOFromID(MovableMan:GetRootMOID(SceneMan:CastMORay(self.Pos,(self.Vel * -50),255,0,true,3)));

If this script works on a weapon then i guess you want the raycast to ignore allies

self.parent = MovableMan:GetMOFromID(MovableMan:GetRootMOID(SceneMan:CastMORay(self.Pos,(self.Vel * -50),self.parent.ID,self.Team,255,true,3)));

But otherwise, try this

self.parent = MovableMan:GetMOFromID(MovableMan:GetRootMOID(SceneMan:CastMORay(self.Pos,(self.Vel * -50),self.parent.ID,-2,255,true,3)));

Thank you for the help I will give your code a try
