Well, here's the complete and unabridged source code of my command-line Engine Calculator. I plan to later include an actual Engine Table, including weights and ratings for XL Fusion, Light Fusion, Compact Fusion, XXL Fusion, Fission, Fuel Cell, Internal Combustion, Primitive Engines, ProtoMech Engines (ratings under 40), and perhaps even Lithium-Fusion Engines (despite those not being canon).

I also plan to include different unit types, such as Ground Vehicles (which multiply Fusion/Fission engine weights, and which also have a suspension factor) and ProtoMechs (which calculate their top speed very differently).
_ _ _ _ _
Code:
print ("Welcome to MechEngine, an Engine Calculator for BattleTech, written in Python 3.6.5.")
print ("Currently, only standard Fusion Engines and standard BattleMechs are available,")
print ("and engine weight has also not yet been implemented.")
print (" ")
tonnage = int(input("Please provide the your 'Mech's Tonnage: "))
cruise = int(input("Please provide your desired Walk MP: "))
flank = int(cruise * 1.5)
print ("Calculating...")
rating = (tonnage * cruise)
print (" ")
print ("Your calculated Engine Rating is:", rating)
print ("Your cruising speed is", int(cruise * 3), "m/s")
print ("Your top speed is", int(flank * 3), "m/s")
print (" ")
print ("To find your engine weight, please look up your engine type and engine rating on")
print ("the Master Engine Table, as shown on Page 49 of TechManual, and for")
print ("XXL Engines, divide the mass of a standard engine by 3 and round to the next half-ton.")
print (" ")
print ("Thank you for testing MechEngine. Please be sure to send feedback. More features coming soon!")

It has an unfortunate bug... it does not round up Run MP correctly, and I'm not sure how to fix that yet. You see, it is supposed to round up, but Python is rounding down.

I'm also using Meters per Second, instead of Kilometers per Hour, because trying to use Floating Points gives me this:
_ _ _ _ _
Please provide the your 'Mech's Tonnage: 55
Please provide your desired Walk MP: 5
Engine Rating: 275
Your cruising speed is 54.0 km/h
Your top speed is 75.60000000000001 km/h

_ _ _ _ _

Oops.

If anybody could help out with this, and any other oversights, please let me know.

Known problems with this version:
- No minimum or maximum tonnage
- No support for alternate engine/unit types
- Engine weight and Master Engine Table not yet imlemented
- No minimum or maximum engine rating
- Incorrect Run/Flank MP rounding
- No rounding of 'Mech tonnage to 5 ton increments
- No rounding of engine rating to increments of 5
- Command-line only.

The attachment is a text file containing the current version of the source code, as of this post. Attachment (213 downloads)

Verified, it works in both Visual Studio and the Python 3.6.5 shell.

However, while I have the Minimum/Maximum Tonnage rules, Minimum/Maximum speed rules, Oddball Tonnage rules and Engine Rounding rules all defined, I have not actually implemented them yet. I don't really know how to apply limiters to inputs at the moment.

Current design goals:

Code:
 (not really, just formatting)

00: Include example units for new users to choose from, to demonstrate how things work ("XX means it cannot be implemented yet.)
- Bushwacker, used in all of my test runs, has a tonnage of 55, a Walk MP of 5, a Run MP of 8, and an engine rating of 275.
XX - It uses an XL Fusion Engine.

- Atlas has a tonnage of 100, a Walk MP of 3, a Run MP of 5, and an Engine Rating of 300.
- It uses a standard Fusion Engine.

- Timber Wolf (Mad Cat) has a tonnage of 75, a Walk MP of 5, a Run MP of 8, and an Engine Rating of 375.
XX - It uses an XL Fusion Engine.

- The Dire Wolf (Daishi) has a tonnage of 100, a Walk MP of 4, a Run MP of 6, and an Engine Rating of 400.
XX - It uses an XL Fusion Engine.

XX - The Sprite ProtoMech has a tonnage of 15, a Walk MP of 3, a Run MP of 5, and carries a 75-rated Engine.
- ProtoMechs calculate Engine Rating differently than BattleMechs, and thusly are slower.
- The Sprite carries 5 Extended Jump Jets, each weighing .30 tons.

XX - The Prodigal Son BattleMech has a tonnage of 60, a Walk MP of 4, a Run MP of 6, and carries a 300-rated engine.
- The Prodigal Son, ordinarily, would use a 360-rated engine, but carries a Lithium Fusion Engine.
- Damage to the batteries in the Lithium Fusion Engine will produce extra heat and reduce its movement speed.
- Lithium Fusion Engines are a non-canon invention, but operate similarly to a Hybrid Car.

XX - The Mackie has a tonnage of 100, a Walk MP of 3, a Run MP of 5, and carries a 360-rated Engine.
- Because it is a Primitive BattleMech, it uses a Primitive Fusion Engine.
- A 360 Primitive Engine has the same performance as a lighter, modern 300-rated Engine.
- Primitive Engines can be used in modern units, but do not perform any better than they would in a Primitive unit.
- Primitive units cannot use modern engines.

- The UrbanMech has a tonnage of 30, a Walk MP of 2, a Run MP of 3, and carries a 60-rated engine.
- The UrbanMech carries a standard Fusion engine, and 2 Jump Jets.

01: Enforce universal minimums and maximums:
- Limit maximum (mech) tonnage to 200
- Limit minimim (mech) tonnage to 10
- Limit minimum (protomech) tonnage to 2
- Limit maximum (protomech) tonnage to 15
- Limit (mech) tonnage to increments of 5
- Limit engine ratings above 40 to increments of 5
- No engine can exist above rating 500
- ProtoMechs cannot have an engine rating less than 2
- All other units cannot have an engine rating less than 10
- A unit has a minimum Engine Rating and a maximum Engine Rating both equal to a multiple of its tonnage, and then subtracting any Suspension Factor it might have. It still cannot have an engine rating below 10, even after subtracting Suspension Factor.

02: Incorporate Master Engine Table for determining (engine) tonnage.
- May need to create a separate file and import it.
- Preferably being able to import external XML, Excel, CSV or SQL databases
- Python version is most likely

03: Incorporate different types of engines;
- XL Fusion Engines weigh half as much as standard Fusion engines, to a minimum of 0.5 tons
- XXL Fusion Engines weigh one third as much as standard Fusion engines, to a minimum of 0.5 tons
- Compact Fusion Engines weigh 1.5 times as much as standard Fusion engines
- Except for ProtoMech engines under rating 40, all engine weights are rounded up to the next 0.5 tons
- ProtoMech engines under rating 40 multiply their engine rating by 0.025 to find their tonnage
- Don't forget Fission Engine, Internal Combustion Engine and Fuel Cell weights
- Incorporate Primitive Engines, which have 1.2x the rating of equally powerful newer engines
- Incorporate Lithium Fusion Engines, which provide a suspension factor equal to 1x your mech's tonnage.
- Engine ratings greater than 400 occupy 2 additional spaces inside the center torso
- XL and XXL engines occupy space in the side torsos. XXL engines also produce more heat.
- Compact Engines occupy half as much space as a standard engine. They cannot exist in ratings above 400.
- Fuel Cells and Internal Combustion Engines cannot power Gauss Rifles or most energy weapons

04: Incorporate Heat Sinks
- Internal Combustion, Fuel Cell, and Fission engines provide 0, 1 and 5 "weight free" heat sinks respectively.
- Fusion Engines and their derivatives provide 10 "weight free" heat sinks.
- A certain number of heat sinks (including but not limited to the "weight free" heat sinks) can be mounted inside the engine
- The formula for in-engine heat sinks is equal to Engine Rating / 25, rounded down.
- If the engine rating is less than 250, then not all of the weight free heat sinks can be put inside the engine.
- Compact Heat Sinks double the number of heat sinks that can be mounted inside the engine.
- ProtoMechs do not receive free heat sinks.
- Ground vehicles and ProtoMechs cannot carry most energy weapons unless they have enough heat sinks to dissipate the heat.
- Double Heat Sinks and Laser Heat Sinks dissipate heat twice as efficiently as standard Heat Sinks, but are bulkier.
- Two Compact Heat Sinks can fit in the space of one standard Heat Sink, but a single Compact Heat Sink is 50% heavier than a standard Heat Sink
- ProtoMechs can only use ProtoMech Heat Sinks, which weigh 25% as much as a standard HeatSink.
- Only ProtoMechs can use ProtoMech Heat Sinks. Double/Laser versions of ProtoMech Heat Sinks do not exist.
- Laser Heat Sinks do not perform more efficiently underwater or in cold environments, but do not perform less efficiently in hot environments or in vacuum.
- Laser Heat Sinks cannot benefit from coolant trucks, but do not suffer from coolant degredation.
- Laser Heat Sinks reduce the chances of an ammunition explosion, but make a mech more visisble at night.
- Different Heat Sinks cannot be mixed inside a mech.
- The "Weight-Free' heat sinks provided by an engine can be any type of heat sink, as long as all other heat sinks on the mech are the same type.

05: Incorporate different unit types:
- ProtoMechs calculate engine rating based on their Run/Flank MP * their tonnage, instead of their Cruise/Walk MP
- Ground vehicles have a suspension factor, which is subtracted from their final engine rating
- Ground vehicles multiply the engine weight by 1.5 for Fission Engines, Fusion Engines, and their derivatives
- HoverCraft have a minimum engine weight equal to 20% their total tonnage. They cannot be constructed heavier than 50 tons, but they have the highest Suspension Factor of any known vehicle.
- ProtoMechs cannot carry special engine types, only standard Fusion engines.
- Land Air 'Mechs cannot carry special engine types, only standard (or compact) Fusion Engines. They also cannot be constructed heavier than 55 tons.
- Hover Tank 'Mechs can use special engine types, but are a non-canon unit type. They also cannot be constructed heavier than 50 tons. When in Hover Tank mode, they have the same Suspension Factor as a Hovercraft of the same mass. However, because they must still be able to operate in other modes, this Suspension Factor does not reduce their engine rating, and merely increases their top speed while in Hover Tank mode.
- SuperHeavy Mechs cannot use Fuel Cells, Fission Engines or Internal Combustion Engines.

06: Incorporate Gyros:
- Standard Gyros have a weight equal to the Engine Rating divided by 100, rounded up to the next full ton.
- XL Gyros halve the Standard Gyro weight, but occupy 50% more space. They cannot be used on engine ratings greater than 400.
- Compact Gyros multiply the Standard Gyro weight by 1.5
- Heavy-Duty and SuperHeavy Gyros double the Standard Gyro weight.
- ProtoMechs, and mechs using Interface Cockpits, do not need gyros.
- Because Land Air 'Mechs have Gyros, they ignore the rule that Aerospace fighters must carry their weight symmetrically.
- SuperHeavy mechs can only use SuperHeavy Gyros. SuperHeavy mechs cannot use Interface Cockpits.

07: Incorporate Jump Jets:
- No more standard Jump Jets can be installed than a unit's Walk/Cruise MP.
- No more Improved Jump Jets or Extended Jump Jets can be installed than a unit's Run/Flank MP. They weigh twice as much as standard Jump Jets, but produce half as much heat.
- Vehicles need to use Vehicular Jump Jets. Aside from not producing heat, they are identical to standard Jump Jets.
- No more Underwater Maneuvering Units can be installed than a unit's Walk MP. They weigh the same as standard Jump Jets.
- Different types of Jump Jets cannot be used on the same mech.
- Land Air 'Mechs need a minimum of 3 Jump Jets installed.
- ProtoMechs have access Extended Jump Jets, instead of Improved Jump Jets.
- Standard Jump Jets weigh varyingly depending on the class of mech:
- 0.5 Tons for mechs in the 10-ton to 55-ton range.
- 1.0 Tons for mechs in the 60-ton to 80-ton range.
- 2.0 Tons for mechs in the 85-ton to 100-ton range.
- Mechs greater than 100 tons cannot mount any kind of Jump Jet, not even Mechanical Jump Boosters.
- ProtoMechs have much lighter Jump Jets, but I do not remember their weights.
- Each Jump Jet provides a jumping distance of 30 meters, or 1 hex. A mech carrying the maximum number of standard Jump Jets can therefor jump as far as it can walk in the same span of time.
- Jump Jets produce 1 point of heat per Hex traveled, to a minimum of 3 heat, even if fewer than 3 hexes are traveled.
- Mechanical Jump Boosters enable a mech to jump without producing heat, even when underwater, but they cannot be combined with Partial Wings, and weigh 5% of a mech's total weight for every 30 meters of jumping distance desired. They can be combined with Jump Jets, but cannot be used in the same turn, and they also cannot allow a mech to change direction while in mid-air (or to land on enemy mechs).

08: Incorporate Physical Enhancements:
- MASC enables a mech to run at twice its Walking speed for short periods, but can cause severe (and permanent) damage to its leg actuators.
- Triple Strength Myomers (TSM), when the mech reaches 9 points of overheat, increase its Walking Speed by 2. Running speed is recalculated normally. They cannot be combined with MASC.
- The Actuator Enhancement System makes piloting rolls easier, but it cannot be combined with TSM or with MASC.
- Superchargers enable a mech to run at twice its Walking speed for short periods, but can cause severe damage to the engines. They are compatible with both MASC and TSM, and when MASC and Superchargers are used at the same time, a mech can run at 2.5 times its Walking speed. The chance of catastrophic failure while doing so increases significantly, however.
- Partial Wings can be installed on a mech, which enable it to jump further and dissipate more heat while it is in an atmosphere. However, the bonuses must be calculated differently depending on both gravity and atmospheric density. It weighs 7% of the mech's total weight for Inner Sphere mechs, 5% of the mech's total weight for Clan mechs, and 20% of the ProtoMech's total weight for ProtoMechs. Land Air 'Mechs and Hover Tank Mechs cannot mount Partial Wings.
- Mechs greater than 100 tons cannot use any physical enhancements.

09: Make the tool cross-platform.
- Windows, OS-X and Linux (Portable)
- Android
- iOS
- Entirely open-source.

10: Give the tool a proper GUI.

I have discovered a bug where the program would crash if the user enters a blank input in response to either question. The program also seems to crash in response to any input on some mobile interpreters, such as Sololearner.

If somebody could help me fix this, that would be much appreciated.

NEW VERSION, PODSPACE!
You must install Python 3.6.5 to run this program.

Code:
# MechEngine, "Examples" build
# Build Date: 2018-05-07

#Objectives of this build:
#Fix crash on receiving blank input for tonnage or movement speed
#Set default mech name if user enters blank value
#Reset input calls when outside specified ranges, such as Walk MP of 45 or tonnage of 1
#Remove SuperHeavy Mechs (for now)
#Add Gyro Weight (standard only)
#Add Internal Structure Weight (standard only)
#Add Cockpit Weight (standard cockpits only)
#Calculate remaining Pod Space
#Add more engine types

Bugfixes and New Features:
1. I fixed a crash that occurs if the user tries to get an engine rating above 500
2. I added a warning that will display if you end up with an engine rating higher than 500
3. I added warnings which display if your mech has negative podspace, or if the engine tonnage exceeds the mech's tonnage.
4. Engine Ratings above 500 are now extrapolated via a polynomial function.

Latest version is out, and I'm pretty sure that it's far too big to put the raw code for it in this post, but I'm going to try.

In the meantime, here's a list of some new features and bugfixes.
- Primitive Engine rating now displays correctly, and only when Primitive Engines are used.
- Primitive Gyros and Primitive Cockpits now calculate correctly, and are only used when Primitive Engines are used.
- ProtoMech engines are now available if your Tonnage is 15 or less.
- Speed now displays in Kilometers Per Hour, instead of Meters Per Second.
- If a ProtoMech engine is selected, the correct formula is used to determine its weight if the rating is below 40. If the rating is 40 or above, then it will instead use the Master Engine Table.
- ProtoMech Engines do not use Gyros and will use an appropriately weighted cockpit.
- Primitive Engines and Lithium-Fusion Engines are now available, and will calculate the Engine Rating correctly.
- If the calculated Podspace is either 0 or a negative value, then the readout message for Podspace will change to indicate that you cannot carry any weapons, armor or equipment.
- SuperHeavy units are back! What's more, they calculate their Cockpit, Internal Structure and Gyro weights correctly, and the available engine types are restricted to Fission Engines, Fusion Engines and their derivatives.
- Alternate Gyro types are now available, except for SuperHeavy Mechs (which use SuperHeavy Gyros) and ProtoMechs (which do not have Gyros).
- If the Engine Rating exceeds 400, then Compact Engines and XL Gyros are not available. It also tells you to select a Large Engine type, instead of just an Engine type.
- If the Engine Rating exceeds 400, and then drops back into the 400 range if you select a Lithium-Fusion Engine, XL Gyros become available again.

I have successfully constructed a Mackie, an Atlas, an Atlas Lithium (Lithium Fusion test run), a Dire Wolf, a Bushwacker, and the UrbanMech UM-WTF IIC with the help of this tool. I have also published the code on Google Drive.

Quick bugs found:
- I forgot to prohibit SuperHeavy mechs from carrying Fuel Cells.
- I accidentally set the weight of a SuperHeavy Cockpit to 5 tons instead of 4
- I forgot to change the internal structure type of ProtoMechs from Standard Internal Structure to ProtoMech Internal Structure.

I intend to fix all of these issues before the next release. That is all~!

Future development of the software has been cancelled. It has reached a point that most of the important features have all been implemented (besides cockpits and internal structures), and I cannot actually work on it any further because of unrelated outside factors.

I am sorry if anyone was actually looking forward to the next version release, but as I had stated before in previous posts, it is Open-Source. You will still need a Python 3 interpreter and editor to run it and make any changes, and if you have any questions regarding the code itself, do not be afraid to contact me on Discord. (My Discord tag is "Amaroq Starwind#1092")

Here is the latest code release.

MechEngine: Beta (Build: 0.30.92)
Today, we have two new releases. The first is a general bugfixes build, and the second was developed concurrently by one of my friends, which adds the ability to restart the program.

I also added some example mechs. Feel free to check them out!
