A smoke container is effectively a PFX (particle effects) emitter that defines smoke and similar effects produced by assets. Smoke tags take the form smokeX where X is a number. There is no maximum number of smoke tags but they must be numbered sequentially (i.e. smoke0,smoke1,smoke2,etc). Smoke blocks have two sections: main and sequence properties. Main properties describe the attributes that stay the same for the life of the emitter. Sequence properties describe a set of one or more phases/periods in the smoke emission sequence.

Contents

[edit] Main Properties

[edit] accel

Type: Decimal List
Default: 0,0,0
Compulsory: No
Desc: Sets the acceleration conditions for the smoke particles. First value is gravity, second is (optional) wind effect. Default is 0,0. A third (deprecated) form exists with three parameters - this uses the first two values to calculate the wind effect and the third as gravity.

[edit] attachment

Type: String
Default: ""
Compulsory: Yes (3.4)
Desc: The name of the attachment point at which to generate the PFX. Attachment points are specified in the mesh file during creation.

[edit] conesize

Type: Decimal List
Default: 0.2,0.2,1
Compulsory: No
Desc: Specifies the cone in which the particles are emitted. When a particle is created it will be given an initial velocity vector with its direction being a random vector in this cone and its speed being taken from the 'velocity' tag. The cone tag is a decimal list of 1, 2 or 3 values (in meters). The first two values specify the width and depth (x and y) of the cone, and the third value specifies it's height. If the height isn't provided a value of 1 will be used, if only one value is provided it will be used for both the width and height. The default value if the tag isn't provided at all is (0.2,0.2,1.0).

[edit] direction

[edit] mode

Type: String
Default: "time"
Compulsory: Yes (3.4)
Desc: The PFX emitter mode. Smoke effects can contain a number of cycled 'phases', the mode defines how the 'start' and 'period' tags are interpreted to control the progression between each smoke phase. Mode must be one of the following values (defaults to "time" if not specified).
Mode Value Description
time 'start' is a list of time values (in seconds) after the creation of the parent object when the next phase of the effect will start, 'period' is the duration of time the phase will remain active.
timeofday 'start' is the time of day to start the next phase. The time of day is specified as a decimal from 0 to 1, where 0 is 0:00.00 AM and 1 is 12:59.59 PM.
anim 'start' specifies a time in the assets animation cycle to start the next phase. 'period' is the time over which the phase is active. The time in the anim cycle is specified as a decimal between 0 and 1. 'start' + 'period' must not exceed 1.
anim2 Same as 'anim' with some additional tags (interpolate, loop, loopdelay)
speed 'start' is a speed, in meters per second, to start the next phase. 'period' is not used.
custom UNKNOWN
cyldrainl Toggled on and off by the Draincock command. The significance of "l" vs "r" is unknown.
cyldrainr Toggled on and off by the Draincock command. The significance of "l" vs "r" is unknown.
stack Synchronized to the drivers and is meant for a steam locomotive's smoke stack.
whistle Turns on and off when the whistle is turned on and off.
generator UNKNOWN
lowpressurevalve Turns on when the boiler pressure exceeds the low pressure safety valve's setting (defined in enginespec). (?)
highpressurevalve Turns on when the boiler pressure exceeds the high pressure safety valve's setting (defined in enginespec). (?)
blow0 UNKNOWN (blowdown?)
blow1 UNKNOWN (blowdown?)
fire-temperature UNKNOWN
boiler-temperature UNKNOWN
Only the 'time' and 'timeofday' modes are valid for scenery objects, other modes are intended for use with assets such as locomotives.

[edit] texture

Type: KUID
Default: <kuid:-1:6329>
Compulsory: No
Desc: Sets the kuid of the texture to use for the particles, defaults to <KUID:-1:6329> (Steam).


[edit] Sequence Properties

Per-phase tags are specified as value lists. If a list is included and if it is applicable to the mode then the number of items in the list must be the same as the number of phases (ie: the number of items in the 'start' list).

[edit] color

Type: Color List (RGBA, 0 to 255)
Default: 255,255,255,255 (if not compulsory)
Compulsory: Yes (3.4)
Desc: Specifies the initial color of the PFX texture. From build 2.9, failing to include a color tag will create a validation warning or error. Note: This is a per-phase tag so the number of (4-element) colors should match the number of phases. However, it is also valid to provide a single color to be used for all phases.

[edit] dampening

Type: Decimal List
Default: 0.02
Compulsory: No
Desc: The spring damping constant for particles created in this phase. The spring damping constant affects the 'stability' of the link between individual particles (see 'spring'). Requires the 'enable-steam-physics' tag. Defaults to 0.02.

[edit] drag

Type: Decimal List
Default: 0.36
Compulsory: No
Desc: The drag constant for the particle created in this phase. This specifes the resistance against the particles ability to move freely through the air. If not specified the drag constant will default to 0.36, increasing the value will cause particles to be more strongly affected by wind. Requires the 'enable-steam-physics' tag.

[edit] endcolor

Type: Color List (RGBA, 0 to 255)
Default: 255,255,255,255 (white, opaque)
Compulsory: No
Desc: Specifies the ending color of the PFX texture. Note: This is a per-phase tag so the number of (4-element) colors should match the number of phases. However, it is also valid to provide a single color to be used for all phases.

[edit] lifetime

Type: Float list
Default: 3
Compulsory: Yes (3.4)
Desc: Specifies the time, in seconds, that the particles exist for in this phase (defaults to 2).

[edit] mass

Type: Decimal List
Default: 1
Compulsory: No
Desc: The initial mass, in kilograms, of the particles created in this phase..

[edit] mass-scale

Type: Decimal List
Default: 0.5
Compulsory: No
Desc: The percentage of mass lost over the particles life time for this phase. This allows particles to become lighter as they dissipate into the air. The value is specified as a percentage where 1 is 100% and will default to 0.5 (50%).

[edit] maxsize

Type: Decimal List
Default: 3
Compulsory: Yes (3.4)
Desc: Specifies the ending size of the particles created in this phase. Note: This is a per-phase tag so the number of list items should match the number of phases. However, it is also valid to provide a single value to be used for all phases. (TBD - Units?),

[edit] minsize

Type: Decimal List
Default: 0
Compulsory: Yes (3.4)
Desc: Specifies the starting size of the particles created in this phase. Note: This is a per-phase tag so the number of list items should match the number of phases. However, it is also valid to provide a single value to be used for all phases. (TBD - Units?),

[edit] period

Type: Decimal List
Default: -1
Compulsory: No
Desc: Specifies the duration of this phase, 'period' behaves differently depending on 'mode' and is not always used (see mode for details). Period can be set to -1 to imply that the phase is active until the next phase begins or the last phase ends: this is the default behaviour. (Note: only mode "time" valid?) (Note: Current validation does not check the count of items in the period list?)

To produce continuous smoke with a scenery item use a mode of 'time' and a period of -1.

[edit] physics-delay

Type: Decimal List
Default: 0
Compulsory: No
Desc: Delay, in seconds, before particles are affected by world physics. This must be added for 'dampening' to work.

[edit] rate

Type: Integer List
Default: 4
Compulsory: Yes (3.4)
Desc: Specifies the rate of particle emission in each phase. For most modes this is set to the number of particles to emit per second, for 'anim' and 'anim2' however this is the number of particles to emit over the animation period. The default rate is 4. See also 'minrate' and 'maxrate'.

[edit] spring

Type: Decimal List
Default: 0.17
Compulsory: No
Desc: The spring constant for particles created in this phase. The spring constant specifies how the strong the link is between individual particles. By default the spring constant is 0.17 if not specified, increasing the value will cause the particles to be more rigidly linked to each others movement. Requires the 'enable-steam-physics' tag.

[edit] start

Type: Decimal List
Default: 0
Compulsory: No
Desc: Specifies when to start this phase, 'start' behaves differently depending on 'mode' (see mode for details). Start will default to a single item with a value of 0. The number of items in this list defines the number of phases.

[edit] velocity

Type: Decimal List
Default: 1
Compulsory: Yes (3.4)
Desc: Specifies the initial speed of the emitted particles for this phase. Speed is specified in meters per second, the default value is 1m/s.
