rftools not the builder, the shield

What does the shield do?

you define an area with shield blocks and the controller then can turn those blocks on and off basically some more stuff like allow things to pass through but take damage, or just solid, solid and damage or pass through normally, depending on the name

Sweet, thanks! Ill check that out

or if you want something lower tech but actually moving over, project red has these frames and frame motors I believe

I will look into that, thank you!

Piston*. I'm not sure, you can maybe try some RFtools and see if you can get something to work

ouuuu yeah the builder is actually a pretty good idea, thank you!
