"If you are referring to the strategical layer, that is currently in rough work and what is expected is in the current public build section, also above." - what I said in my reply
Current Public Build
Basic designers up to the company level with tools to get your designs ready for the combat demo.
^ this is the section I mentioned. There is currently no combat demo as it is still being worked on!
Follow the installation guide above and play with the designer features. If you are referring to the strategical layer, that is currently in rough work and what is expected is in the current public build section, also above.
This is usually a telescope on a tripod that identifies the position of the station directly and lets the heliograph light point in the exact direction it needs to. The naked eye also has much less of a range limit per square cm of heliograph or signal light compared to a dedicated telescope receiver.
The game is always moving from playable state to playable state. Combat is currently in testing and is very rough, and I am very busy. I would say the combat portion would be out in a year or two?
Those are definitely interesting and I would like to get to them in the future but not priority. For chemical and biological warfare it will either be abstracted or changed to a fictional system as I don't plan on making irl designers for those.
The reason why it shows nan in this case is because your propellant is too weak to actually propel the bullet at a meaningful speed.
Some things I noted from a quick lookover:
1. Projectile to casing ratio looks to be off. Generally when you are starting out you always want your projectile to be shorter than your casing.
2. M26 is the most reliable propellant to use as RLG can get pretty crazy if you don't experiment with it significantly. With that, your propellant grain is also very massive for a small arms cartridge. You want many small propellant grains for a faster burn, ex 1mm or sub 1mm grains. You can visualize this by seeing how different shapes burn in real life!
You also may want to play with perforated grains if desired performance is not met due to perforated grains being able to burn from both the outside and inside at the same time leading to a neutral burn time graph.
