Is it possible to make a project obsolete?

[ITcore]

My goal would be to have a project that creates a special unit. At a certain tech, you can make another project (1 time) and it will obsolete the other project while granting you a nice one time bonus. This isn't something that can be done with simple XML/SQL variables but I'm wondering if it's possible in LUA?

You could do it by granting and then removing a dummy Resource, since projects can be dependent on Resources.

Would this dummy resource be invisible to the resource tracker? As in, it wouldn't appear in the bar up top and be something that can't be traded?

It would probably show up, but you may be able to make it a Bonus Resource instead of a strategic or luxury one. I don't know if it would work.

I'm not too sure either. I wonder if it would be possible to write a script that deletes an old project when a new one is done. Is that something that is possible? I don't know LUA well enough.
