Oh, sorry. Our script
Not sure there is even one single line left from the original thou.
Well, the XRZ is impossible to get without cheating, and from the name "Extration Robot XR-TEST" in it's voxelinfo file I got the feeling it's never even supposed to be in the game.
Already the XR-2 robots are very costly to make. So I see this more as a way of using lots of XR-1 that are very easy to make. And since the Atomic Compressor is also really easy to make, the only thing complex you need to make is one single Programmable Robot, and you can have your self an small army. That's why I feel it may be to powerful. There is really no need to make any more advanced Robots. Seeing that the XR-2 is the robot that takes the longest of all Robots to mine it's designated area. I haven't done any exact measurements, but I got a feeling it's just 25% faster then the XR-1.
But with just 6 compressors and 24 XR-1, it still takes plenty of time to mine stuff.
So far I haven't run the script even once in my "real" play world.
The real work will come when you are going to build the fully automated factories to make all the parts needed to make your fully automated factories. All those Materialized/Dematerializers you will be needing takes forever to make.
Not much left to test in the script now. But it takes forever to run the tests. I wish there was a Robot that mined a much smaller area so it didn't take so long to run the tests.
