the projector question.

[DeafNTaxes_TTV]

So I want the projector to move and while it is moving always keep a block were it moves to without losing the block or stop projecting what I need it to make. So for example a train that prints its own track but dont have the projector set some were so it projects that image were its going to go. I want it to have it so the projector is on the moving train so it always makes the block it needs to. Ooo and with out having to code anything I dont know how to do that

Should be possible, but will require merge blocks and connectors, have a search for some space elevator printing machines, same concept except vertical for them.

Oh, boy. That's gonna be a major pain.

You can make a train that prints its own rail, but you'll need to link the projector to the rail with a merge block while you're printing.

Here's something similar I made in the past.

It was extremely time consuming, and extremely unfun. This can be done without code too, but you'll need to drive pretty much everything with a series of timer blocks. Where timer A will trigger Timer B and so on, which is also extremely time consuming and unfun. You can see the wall of timers in the video.

Part of the reason why the drill ended up so complex is that I wanted the drill itself to be printable in survival. And in order for that to happen it should be able to lock into a single grid. If that's not a requirement in your case, things will get easier, but you'll still have a ton of "fun" essentially riving animated walker robot with timers.

if you have a straight rail for a long distance, you could make a blueprint in creative for all of it in one projection and place a projector on one end of the rail while your train is welding it at slow speed.

But if its not a straight line, you'll need complex system of connectors/merge/timers/pistons

[Buzzard]

You could also make the projector as part of the track being welded. Each section of track would have a projector with the *next* section of track, all lined up and ready. Create that first section, blueprint it, put BP in projector, line it all up, blueprint again, build from the SECOND BP.

Right I was thinking something more like this. https://www.youtube.com/watch?v=2wkAMchMJAg&list=WL&index=4&t=1054s were you make the road as you dig. tho the problem is making the connection to the surface every so often. So you can recharge and dump what you aren't using.
