Relative Top Speed

Description
Features
- User defined speed limits
- Control the speed of individual ships based on mass and acceleration
- Change configuration on the fly (no need to restart)
- Multiplayer ready

Description
Imagine you are in a fighter chasing down an enemy ship. You are closing the gap but just before you get in range they hit 100m/s. Then there's this awkward feeling of hopelessness as you both drift into oblivion. By introducing Cruise speed, a soft speed limit based on mass, and Boost, bonus potential speed based on ship acceleration, this mod defines simple, intuitive, ship classes.

The Nit and Grit
Speed Limit: This is the speed limit implemented in Space Engineers (set to 140m/s by default)

Cruise Speed: This is the maximum speed that the current grid can maintain without continuous acceleration. Cruise speed is determined purely off of grid mass and is calculated on a slight curve giving better results the lighter the ship is.

Boost: beyond cruise speed a resistance force is applied to the grid. A grids boost speed can be calculated like this.
Max Boost = Cruise speed + [acceleration / resistance multiplier]

Ignore Grids Without Thrust: setting this to true will stop all resistance forces on grids that have no thrusters on them. This is to allow gravity cannons and such to still be effective.

Chat Commands
/rts help - lists commands
/rts config - shows maximum and minimum values for grids
/rts hud - displays useful numbers when in cockpit (use this when building)

Default Settings
- Speed Limit: 140 - Ignore Grids Without Thrust: true - Ignore Grids Without Cockpit: false Large Grid - Min Cruise: 60 - Mid Cruise: 80 - Max Cruise: 110 - Mass at Min Cruise: 8M - Mass at Mid Cruise: 5M - Mass at Max Cruise: 200,000 - Resistance Multiplier: 1.5 Small Grid - Min Cruise: 90 - Mid Cruise: 95 - Max Cruise: 115 - Mass at Min Cruise: 400,000 - Mass at Mid Cruise: 300,000 - Mass at Max Cruise: 10,000 - Resistance Multiplier: 1.0

Configuration

There is an API for any modders looking to get speed information about ships. To access it just unzip this mod and copy the RtsApi.cs file into your project.

To configure general default settings for all worlds go to:
%AppData%/Roaming/SpaceEngineers/Storage/1259618037_rts/RelativeTopSpeed.cfg
or
Torch/Instance/Storage/1259618037_rts/RelativeTopSpeed.cfg

To configure world settings go to:
%AppData%/Roaming/SpaceEngineers/Save/(GameSave)/Storage/1259618037_rts/RelativeTopSpeed.cfg
or
Torch/Instance/Save/(GameSave)/Storage/1259618037_rts/RelativeTopSpeed.cfg

If you need help with setting up your config post your current config and your desired outcome and ill help get you on track.

What you need to think about when configuring the mod. What is the overall speed limit i want? 100m/s 250m/s? What is the most massive ship i expect to see on server? 500k? 8M? 20M?... What is the minimum speed i want my heaviest ships to move? 60m/s? 100m/s 150m/s? How light do i want to force people to build to get max cruise? 200k? 1M? How much head room do i want to leave for boosting? (MaxCruise=WorldSpeedLimit - headroom) Do i want to favor lighter or heavier grids? If not set the mid values to the value between min and max. Finally tune the resistance multiplier to get boost value you want.

maybe add a sprint to the jetpack

@NanoTree I think the reason for that jetpack is always a bit higher is that you can actually stay inside a large grid. It's dumb... I whish they made the jetpack speed dependant or relative to the next biggest ship but that can't be done in a mod easily

This is nice! Is there any change that you make it possible have different settings in atmosphere and space?
Because for space this does not make sense, so I would set it to something like
cruise=100/max=200 in atmosphere and
cruise=1500/max=1500 in space since there is no friction you know

what I don't understand is why bigger ships can fly slower and have less friction, it should be the other way around, right?

@SepticStorm you're really talking about acceleration and force, and not velocity at that point. Adding more engines will add more thrust (force output), which will be more expensive, so that is kind of already a thing in the game. You could calculate how much fuel it would take to get to light speed in the game using only thrusters, but it gets complicated when considering that the mass of your ship is changes as you burn off fuel versus the number of thrusters. But basically, your acceleration should improve as you burn off fuel.

In real life, the amount of fuel needed to reach light speed and the mass of that fuel is what would be impractical and where you get diminishing returns. E.G. more fuel weighs more and takes more force to push which means more thrust which burns more fuel, which means more mass from the thrusters themselves, etc.

would love to use this mod but it is not appearing in my mod list, any advice?
SepticStorm 13 May @ 6:47pm 
I have thought about this a lot, I would really like to find a similar mod. but instead of "boost" mode. make adding velocity more and more expensive. either by decreasing thrust efficiency, or by increasing the required fuel (h2/power). in effect making an in game "light speed' (not actually at that fast) where yes the speed is technically possible, however with diminishing returns the "max speed" would take "infinite thrust" just like reaching light speed in real life. but, I know nothing about modding to make this.

is it possable to change the top speed in game?
SnowBubble 12 Apr @ 11:16am 
The path you have for the config file is no longer correct. The ID for the mod changed and is now 1359618037. Awesome mod thank you for making this!
JJ 2 Apr @ 11:15am 
What if I want to get rid of how the mass affects the speed? Can I change all the values for mass to 1?
Arkil 30 Mar @ 3:36am 
Oh this could be even simpler. I'm seeing yawing left and pitching up. My grid CoM is to the left and up from *grid combination* CoM.
Arkil 30 Mar @ 3:15am 
Thinking about this I realize that there are a few exploitable use cases...

You could work around exploits by classifying by mass, outer bounds or occlusion, which ever is fastest.
