is there a way to disable the lockon control for the human via lua so that she/he cannot lock onto other units?

these values define what can be locked/targeted on, the are written in the waponodf, i dont know much about lua, maybe you can change them via scripting...: the detpack has everything set to "0"

here are three additional values:

No; you can't modify weapons in a script. You'll have to have a separate class (with separate weapons) available for your human player.

sorry that i wasnt not clear in my first post. The main goal of my mod is to make the AI better and it harder for the humans with out just making it 1000 vs 1. I am setting up some rifles like rocketlaunchers to test something. I want the AI to be able to lock on while the human not to with out making two sides for each team. I dont want to modify the gun via lua i want to disable the ability to use the control (ie the button "Q")

the problem is that you cant do that via lua as mav said

he said i cant modify weapons, not controls

you can only disable the locking via weaponodfs

the only way to achive what you want would be making a side with all weaponodfs in it which is loaded after the nromal sides, the new weaponodfs would the override the shipped ones

Why not just edit the odfs to make the AI more accurate?

for the
LockOnRange = "100.0"
LockTime = "0.4"
LockOnAngle = "20.0"
are there AI only ones? like
AILockOnRange = "100.0"
AILockTime = "0.4"
AILockOnAngle = "20.0"

this can also make the ai "better"
and its even lua coding!
