Sounds like the script might have thrown an error, if you look at the programmable block it might say 'exeption...etc' basically an error message, does this happen? If so there are two possible solutions depending on your set up.

The program block doesn't say anything

Rdav's test world works, but he did the timer setup a bit differently there. The timer first runs the programming block, then triggers itself AND THEN runs the timer. When I set it up the same way, it works.

EDIT: I read the tutorial more carefully and it says exactly that. Not sure why I didn't catch it earlier. I also didn't read that the sensor has to be called "sensor" and called it "A", like the rest of the blocks. It's a bit unintuitive. I'd like the sensor to be disabled by default and only enable it when I launch the missile.

I've been trying to get this to work on my ship, and it's failing due to being overly complex. I don't recall having this issue in the past. Is this due to the latest updates, or is this due to something on my end? I'll note that your world still seems to work fine.

EDIT - Attaching the missile to your fighter seems to work fine. So...what of my ship design could be causing that issue?

@up Same issue here, program gets overloaded, even tough it worked perfectly fine even I've spammed missiles in unholy ammounts.

make sure its named -PROG-

Mine won't launch, and I think it's because of these errors I get when I compile.

Also, would it be possible for the script to automatically arm attached warheads on the torpedo?

Yeah, add a sensor and make the missile a bit bigger.
