well, I think that would require editing the science ini a bit:
So let me see if i can give an example:
You get the Generals Menu...
You have 5 buttons...
But if you get one, the other ones under it you cant get?
if this is what you are asking, take a look here:
Science SCIENCE_Paradrop3
PrerequisiteSciences = SCIENCE_Paradrop2 SCIENCE_Rank3
SciencePurchasePointCost = 1
IsGrantable = Yes
DisplayName = SCIENCE:USAParaDrop3
Description = CONTROLBAR:ToolTipUSAScienceParaDrop
End
I believe that if you edit the SCIENCE_Paradrop2 to be whatever you want your science is, that should work, because basically what this says is E.G.: You cant get Airstrike 3 unless you get Airstrike 2
and if you want it to be something like different abilities:
E.G. If you get the pathfinder, you cant get the Marine or the next level marine which is the Marinex2, but you can get the S/N Pathfinder.
What you would do is:
Science SCIENCE_S/NPathfinder
PrerequisiteSciences = SCIENCE_Pathfinder SCIENCE_Rank3
SciencePurchasePointCost = 1
IsGrantable = Yes
DisplayName = SCIENCE:USAParaDrop3
Description = CONTROLBAR:ToolTipUSAScienceParaDrop
End
and for the marine
Science SCIENCE_Marine
PrerequisiteSciences = SCIENCE_AMERICA SCIENCE_Rank3
SciencePurchasePointCost = 1
IsGrantable = Yes
DisplayName = SCIENCE:USAParaDrop3
Description = CONTROLBAR:ToolTipUSAScienceParaDrop
End
and marinex2
Science SCIENCE_Marinex2
PrerequisiteSciences = SCIENCE_Marine SCIENCE_Rank3
SciencePurchasePointCost = 1
IsGrantable = Yes
DisplayName = SCIENCE:USAParaDrop3
Description = CONTROLBAR:ToolTipUSAScienceParaDrop
End
Now to the confusing and hardest part:
If you want them to conflict with each other...lets say you can get Pathfinder 1 and 2, but not marine 1 or 2, I think you would have to add a production limit to the barrack somehow. I will try to come up with a way to do it, until then please keep trying...
