Thruster

'''Thrusters''' are the primary source of propulsion for starship cruising.
<br>Thrusters add speed and acceleration in the direction that they are pointing; therefore, applying thrust to one or multiple sides of a ship is possible.
<br>A thruster's exhaust path may not be blocked by any block of the active starship at any distance, with the exception of one glass or glass pane block with no space in between.

Afterburners provide plenty of acceleration and speed in a small package but are less efficient than other thrusters. They are typically the best thruster for most applications.

==Calculation==
The speed and acceleration of a given starship is determined by a number of functions and variables. For this reason, most players simply add thrusters by increment while testing the speed and acceleration values, until either of these values starts going down. That said, the discerning shipwright may still be interested in calculating the optimal thruster count beforehand, to save themselves time and energy.

=== Speed calculation: ===
To begin, let ''t'' = the total sum speed of all thrusters on a ship (for example, if a ship has 3 ion thrusters, then t = 12).

'''THIS IS NOT THE ACTUAL SPEED THE SPACESHIP WILL HAVE'''. Rather, this value is used in two equations to determine the actual ship speed. Firstly, the weight of each thruster must be considered to get the ''effective speed s.''

''s = t * 0.85 <sup>w^0.5</sup>''

Where

''t ='' total speed from all thrusters

''w ='' total weight from all thrusters

The next equation is "calculated speed" ''c'', determined as follows:

''c =(s <sup>0.5</sup> )/ (m<sup>0.2</sup> * 50)''

Where:

''s ='' effective speed

''m'' = mass of the starship

So we can just add thrusters indefinitely to get a super speedy ship, right? '''WRONG!!''' As more thrusters are added, the total weight ''w'' increases, so that the value multiplied by ''t'' will reduce the effective speed.

The next equation is the max speed equation, and it caps the top speed of your starship. The max speed ''v'' is calculated as follows:

''v = (r * 0.4) / s''

Where:

''r ='' reactor output

Note that the max speed also reduces with each thruster you add. Thus, a careful selection of thrusters must be made for optimal ship performance.

=== Acceleration calculation: ===
tbd

=== Source Code: ===
the following code is used to determine the speed and acceleration of ships ingame. The above equations derive from this code.

"effective speed", "calculated speed", and "max speed" are derived from variables totalSpeed, calculatedSpeed, and maxSpeed respectively.
private fun buildThrustData(faceThrusters: List<ThrusterSubsystem>): ThrustData {
if (faceThrusters.none()) {
return ThrustData(0.0, 0)
}

val baseSpeedFactor = 50.0
val speedExponent = 0.5
val massExponent = 0.2
val reductionBase = 0.85
val finalSpeedFactor = 1.0

val mass = this.mass
val totalAccel = 1.0 + faceThrusters.sumOf { it.type.accel }
val totalWeight = faceThrusters.sumOf { it.type.weight }.toDouble()
val reduction = reductionBase.pow(sqrt(totalWeight))
val totalSpeed = faceThrusters.sumOf { it.type.speed } * reduction

val calculatedSpeed = totalSpeed.pow(speedExponent) / mass.pow(massExponent) * baseSpeedFactor

val maxSpeed = if(type.tech2){
reactor.output * .4 / totalSpeed}
else (reactor.output * .4 / totalSpeed)*1.1

val speed = (min(maxSpeed, calculatedSpeed) * finalSpeedFactor).roundToInt()

val acceleration = if(type.tech2) {
ln(2.0 + totalAccel) * ln(2.0 + totalWeight) / ln(mass.squared()) * reduction * 30.0 }
else (ln(2.0 + totalAccel) * ln(2.0 + totalWeight) / ln(mass.squared()) * reduction * 30.0)*1.1
return ThrustData(acceleration, speed)
}
The following code sets the parameters for each thruster type
enum class ThrusterType(val accel: Double, val speed: Double, val weight: Int) {
PLASMA(0.75, 2.5, 1) {
override fun MultiblockShape.buildStructure() {
at(0, 0, 0).thrusterBlock()
