Class ExhaustSmoke

Controls particle emitters that simulate engine exhaust smoke, dynamically adjusting particle properties based on engine RPM, throttle position, and airspeed.

Syntax

[Serializable]
[RequireComponent(typeof(AircraftEngineBase))]
public class ExhaustSmoke : MonoBehaviour

Remarks

Exhaust characteristics change with engine state: at idle or low throttle, exhaust is lighter colored (normal/white smoke), while under heavy load darker soot particles are emitted. Particle lifetime automatically adjusts based on airspeed to maintain consistent visual trail length. Speed, size, and color all scale with engine operating conditions for realistic exhaust behavior.

Fields

lifetimeDistance

Controls exhaust trail length by limiting particle travel distance from emission point. Lower values create shorter trails, higher values longer trails.

Declaration

[Range(0, 1)]
[Tooltip("Maximum distance an exhaust particle can live from the point of emission.")]
public float lifetimeDistance

Field Value

Type	Description
float

Remarks

Trail length remains consistent regardless of aircraft speed by dynamically adjusting particle lifetime.

maxSizeMultiplier

Maximum particle size multiplier at full engine RPM (1-5 range). At idle, particles use base size. At max RPM, size is multiplied by this value.

Declaration

[Range(1, 5)]
[Tooltip("Particle start size is multiplied by this value based on engine RPM.")]
public float maxSizeMultiplier

Field Value

Type	Description
float

maxSpeedMultiplier

Maximum particle speed multiplier at full engine RPM (1-5 range). At idle, particles use base speed. At max RPM, speed is multiplied by this value.

Declaration

[Range(1, 5)]
[Tooltip("Particle start speed is multiplied by this value based on engine RPM.")]
public float maxSpeedMultiplier

Field Value

Type	Description
float

normalColor

Exhaust color at idle or low throttle (light/white smoke). Represents clean combustion with minimal soot production.

Declaration

[Tooltip("Normal particle start color. Used when there is no throttle - engine is under no load.")]
public Color normalColor

Field Value

Type	Description
Color

particleSystems

Particle systems representing engine exhaust. Multiple systems supported for complex exhaust setups.

Declaration

[Tooltip("List of exhaust particle systems.")]
public List<ParticleSystem> particleSystems

Field Value

Type	Description
List<ParticleSystem>

sootColor

Exhaust color at high throttle (dark/black smoke). Represents rich combustion with high soot production under load.

Declaration

[Tooltip("Soot particle start color. Used under heavy throttle - engine is under load.")]
public Color sootColor

Field Value

Type	Description
Color

sootIntensity

Controls how much the exhaust darkens under throttle load (0-1 range). At 0, exhaust remains light regardless of throttle. At 1, full soot color is used at full throttle.

Declaration

[Range(0, 1)]
[Tooltip("How much soot is emitted when throttle is pressed.")]
public float sootIntensity

Field Value

Type	Description
float

targetEngine

Engine whose state controls the exhaust particle behavior. Automatically assigned from the same GameObject.

Declaration

[Tooltip("Target engine of this script.")]
public AircraftEngineBase targetEngine

Field Value

Type	Description
AircraftEngineBase
