Description
[Vanilla|Made for Survival|Subgrids (after assembly)|Scripts]

A piston gun that propels a large warhead through magical piston jolting. It breaks the speedlimit (in vanilla) and reaches around 950 m/s ± your ship speed. The gun is made for survival worlds and comes in a single projectable grid. Assembly required.

Pre-assembled version here!

In order to assemble and fire it, you need to be in experimental mode with scripts turned on!

Are you wondering what the hell this is? Well, a gun basically, try it out, it's fun. And also incredibly overpowered. How does it work? Well basically the pistons are attached on both sides and then retracted with incredibly high force, kinda like strechted springs. Once they are released on one side, they snap forwards, carrying the projectile with them.

What's special about this one?
-it's a single grid (for projecting)
-turns into multiple grids during assembly
-projectile has battery for infinite range
-no timers, all run by one script (only runs while firing)

Some stats:
-Blocks: 55 + 7 per projectile
-PCU: 1192 (+244 per projectile)
-Mass: 27.5 t
-Projectile mass: 5.4 t
-FireRate: up to 15 RPM

Yo guys, just figured it out for myself. I used the comments from you guys and combined them:

1) unsafe piston impulses in world settings
2) share inertia tensor in world settings
3) Doublecheck that the pistons have the correct Max Impulse Axis. Just max this shit out

it does, you need unsafe piston impulses and share inertia tensor on in world settings and everything has to be owned by you, or the prog block can't see the other blocks.

Does this still work? Can't get it to fire.

For everyone struggling to make this work now, I found the issue. Doublecheck that the pistons have the correct Max Impulse Axis, for me it had been reset to the default. The pistons are set to not show up in the terminal by default, so you have to click the icon to show hidden blocks.

This use to work great! I tried to use it recently on the newest version of the game and it wasn’t working right.

same issue

Something seems off, the projectile gets almost no velocity. Used to work well for me, has a patch broken it?

Is the gun up to date with the new update? Along with that, I dont see a button to fire the gun, so I have been directly shooting it through the PB, but it doesnt work. Likely a skill issue on my part, but any help is appreciated

actually after pasting it in a new save, the projectile just falls to the ground instead of being launched.
