Building Question

[Andy Miller]

I am planning out a galacticraft space ship launch pad and I would like to build it underground and of course cover it up on the surface. I would like to use MFFS to make a field that is camo'd like grass over the launch pad.

My question is will the field let the ship and myself pass or will I explode into a million pieces and regret all my life decisions (particularly the design plan).

Thank you for any help on this.

I don't think entities can move through force-fields. It would be smart to turn the shield off when you lift off.

I wonder if flying rockets trigger tripwires?

[phazeonphoenix]

Hey I can speak from experience on this one! You won't explode, but you won't get past the field either. The rocket will simply stop at the field like it was a ceiling. When I tried it I had to get out of the rocket, turn off the field, and the rocket continued without me. Don't remember if I ever tracked it down or not.

Wow, thank you guys!! phoenix I am so glad that not only it has been tested but some came up with the same half cocked idea, .

dwwojcik, you bring up a good point, has anyone tested this with a tripwire??

Computercraft sensor.

Or you could do this the manual way, a switch placed near your launch pad wired to some circuitry to switch off the field for a couple minutes or so.

Neowulf, I never heard of this, but sure enough it is part of the 1.1.0 pack. I am very behind the times. Umm, care to share what kind of script/program needs to be made for that?

Phoenix, that sounds like a good idea too. Would you just have it hooked up to a ton of repeaters with delayed time?

Another idea I had is can the MFFS remote control be used to turn off while in the ship and then on while in launch?

Just keeping my options open.

[phazeonphoenix]

No you'd need more than just repeaters. You'd need to interrupt the redstone signal then re-enable it afterwords. You'd probably have an RS-Latch (set/reset switch) connected to a clock circuit. The Programmable Rednet Controller could do it a lot easier than vanilla minecraft redstone circuitry.

[dwwojcik]

On the contrary, an RS-NOR latch is this easy.

OpenCCSensors has been in tekkit since tekkit lite I believe. Definitely part of the entire range of MC1.5.x tekkit versions.

As for code, http://www.computercraft.info/wiki/index.php?title=OpenCCSensors

The example at the bottom is exactly what you want. Trigger the forcefield projector on/off with a redstone signal based on player proximity and have the sensor near the roof of your launch tube.

For bonus points you can alter it to check the target name and y position and only trigger for certain players in sensor range under a certain height. That way it doesn't open for random players walking ontop of your field.

[phazeonphoenix]

That's a better solution if you can get it working. I'll just add a caveat and say that don't expect anything done with ComputerCraft to be anything near secure. Don't bother with keycode doors or passwords.

[Neowulf]

Computercraft is just as secure as anything in minecraft can be, you just have to figure out how to not do things like a basic computer that controls your front door by waiting for a plain text password and outputting a redstone signal when it matches.
