It's been a while since I've posted or designed, so here's a little something.
Both the missile and the torpedo are functional, and can be placed onto your vehicle. I'm not sure if it's possible to place either on a plane as I made this for an upcoming boat, so the parts may be too large. I tested the torpedo only in water, so I'm not sure if you can launch it from air. This is the first version, meaning it's subject to change (range, agility, control, etc.). Funky Trees free, beginner friendly for those wanting to edit.
They both have pretty decent explosion sizes, but this can be configured to your liking through the property:
Also FYI I was too lazy to move out the cockpit before publishing the final xml, but just remove it from inside the missile if you want to save it as a sub-assembly
Missile: Default launch controls
[AG1- activates decoupler to launch]
[Roll - Left-right yaw]
[Throttle - Speed control]
The red rectangle on the top is the decoupler. You can place this where you want on your vehicle.
This is free to use! But please, credit me, I'd like to have some people check it out and give advice/criticism.
Please Note: the carrier vehicle you used to deploy the torpedo must have fuel, and the engine inside the torpedo consumes fuel from your vehicle. I'm releasing a demo vehicle if you want to see how it works, but the vehicle does not move at all as to not complicate things during testing.
