Controls And Gauges

« [[wiki/Tutorials/SteamLocomotiveValveGear]] | [[wiki/Main/Tutorials]] | [[wiki/Tutorials/IncludeWithRotate]] »

From build 102.3.1

Control desk of class 303 emu showing

  • Controls (Brake control, aws acknowledge button and power control)
  • Gauges (aws indicator, train and main brake gauges and speed)
  • Indicator (slip indicator)

Controls

The Control keyword allows you to specify an animated control in the cab.

Syntax

  ControlX      Component_Name
  ControlY      Component_Name
  ControlZ      Component_Name
  ControlB      Component_Name

where

  • ControlX is used for a control rotating about the x(w) axis
  • ControlY is used for a control rotating about the y(l) axis. A steam loco regulator is typically ControlY
  • ControlZ is used for a control rotating about the z(h) axis. The controls in the screenshot above are ControlZ
  • ControlB is used for a button type control (eg the aws button above), note the different movement parameters
  • is the control parameter to be linked to the control, see [[wiki/Scripting/VehicleDynamics]]
  • is the inclusion point - the origin of the component.
  • specify the rotation of the control, in degrees, with r0 being the angle for the control’s minimum position and r1 the angle for the maximum position
  • are used for button controls and specify the movement of the button component when operated.

examples: 

  ControlZ 	40/0/5 	POWER	45,-80	303PowerControl
  ControlB	-25/15/-5	AWS	0,0,-2  303_AWSPlunger

Hotspots

In order for the user to operate the control, you need to specify the active point on the control (the hotspot) and the direction of movement.

This is done by placing a hotspot term in the control component.

Syntax

  HOTSPOT

where

  • is the parameter this modifies (this must be the same as the control itself)
  • is the position on the control of the hotspot. Ie this is where the user will click to operate the control
  • is the endpoint of the movement arrow (see above) for negative movement of the control
  • is the endpoint of the movement arrow (see above) for positive movement of the control
  • is the amount the control moves when the mouse moves on the screen. (may not be used anymore, suggest set to 10)

example: 

  HOTSPOT Power	-140/0/85	-140/-50/85 	-140/50/85	10

Defines the hotspot on the power control at position −140/0/85 on the control component. The movement arrows are from −140/0/85 to −140/−50/85 and −140/0/85 to −140/50/85. When in driving mode, the simulation draws the movement arrows (red and green, see screenshot above) (provided the user has not turned off the display of arrows)

Gauges

The new igauge keyword allows you to include operating gauges in a locomotive cab. The gauge can be driven by loco dynamic parameters and also script functions (see [[wiki/Scripting/RegenerativeElectric]])

I would have liked to use just “Gauge” but that is already in use, hence “igauge”

Note that the iGauge keyword is used for the moving part of the gauge - ie the needle, the fixed part - the outer casing - would be modelled as a separate component.

Syntax

   IGauge           Component_Name

where

  • is the parameter to be used to drive the gauge, see [[wiki/Scripting/VehicleDynamics]]
  • is the inclusion point - the origin of the component.
  • is the rotation of the component about the x/y/z axes. Rotation is specified in degrees per unit of the parameter, thus (for example) the train speed (in m/s) ranges from (say) 0 to 50 m/s , if the rotation parameter is 4 the component will rotate 4 degree per m/s, so at 50 m/s it will be rotated 200 degrees.
  • is the initial rotation in degrees (when the parameter is zero).

for example 

IGauge	0 -11/-2/143	0/10/0 	0/-160/0	ControlModule_Pointer

would produce a pointer linked to parameter 0 (speed) and starting at −160 degrees and then rotating 10 degrees per m/s

Indicator

An indicator is a lamp (etc) that lights up to indicator a condition (Eg a warning condition, such as the slip indicator above)

Syntax

  INDICATOR

where

  • is the parameter that drives the indicator. see [[wiki/Scripting/VehicleDynamics]] The component is rendered when the parameter is non-zero
  • is the position of the component (as for an include component)
  • is the sub-component

example: 

  # Slip indicator
  INDICATOR	6	0/-2/2	303SlipIndicator

Example

The code below is a simple “vehicle” with a power control and speed gauge: 

 NAME ControlDemo
 Metric
 Length 1000
 Power	100
 Weight	100
 Max	100

 CAB	0/500/150

 
 	ControlZ 	0/50/50 	POWER	0,180	ControlDemo.Control
 

 Fill -200/0/30 200/0/30 200/1000/30 -200/1000/30 0.0.0 =

 # Speedometer
 IGauge		0	70/50/50	0/0/10	0/0/0		ControlDemo.Pointer

 # Slip indicator
 INDICATOR	6	-70/50/50 	ControlDemo.Indicator
