Methods

getClassName

getClassName(): string
Returns name of class of this object.

Returns string
name of class of this object.
Overrides AbstractPath.getClassName
- Defined in sims/roller/SpiralPath.ts:68

getFinishTValue

getFinishTValue(): number
The ending value for t in the parameteric equation defining the path.

Returns number
ending value for t
Implementation of ParametricPath.getFinishTValue
Inherited from AbstractPath.getFinishTValue
- Defined in sims/roller/AbstractPath.ts:70

getName

getName(opt_localized?): string
Name of this object, either the language-independent name for scripting purposes or the localized name for display to user.

The language-independent name should be the same as the English version but capitalized and with spaces and dashes replaced by underscore, see Util.toName and nameEquals.
Parameters
- Optional opt_localized: boolean
  true means return the localized version of the name; default is false which means return the language independent name.
Returns string
name of this object
Implementation of ParametricPath.getName
Inherited from AbstractPath.getName
- Defined in sims/roller/AbstractPath.ts:65

getStartTValue

getStartTValue(): number
The starting value for t in the parameteric equation defining the path.

Returns number
starting value for t
Implementation of ParametricPath.getStartTValue
Inherited from AbstractPath.getStartTValue
- Defined in sims/roller/AbstractPath.ts:75

isClosedLoop

isClosedLoop(): boolean
Whether the path is a closed loop, ending at the same point it starts.

Returns boolean
whether the path is a closed loop
Implementation of ParametricPath.isClosedLoop
Inherited from AbstractPath.isClosedLoop
- Defined in sims/roller/AbstractPath.ts:80

nameEquals

nameEquals(name): boolean
Whether this ParametricPath has the given name, adjusting for the transformation to a language-independent form of the name, as is done by Util.toName.
Parameters
- name: string
  the English or language-independent version of the name
Returns boolean
whether this ParametricPath has the given name (adjusted to language-independent form)
Implementation of ParametricPath.nameEquals
Inherited from AbstractPath.nameEquals
- Defined in sims/roller/AbstractPath.ts:85

setClosedLoop

setClosedLoop(value): void
Sets whether the path is a closed loop, ending at the same point it starts.
Parameters
- value: boolean
  whether the path is a closed loop
Returns void
Inherited from AbstractPath.setClosedLoop
- Defined in sims/roller/AbstractPath.ts:92

setFinishTValue

setFinishTValue(value): void
Sets the ending value for t in the parameteric equation defining the path.
Parameters
- value: number
  ending value for t
Returns void
Inherited from AbstractPath.setFinishTValue
- Defined in sims/roller/AbstractPath.ts:99

setStartTValue

setStartTValue(value): void
Sets the starting value for t in the parameteric equation defining the path.
Parameters
- value: number
  starting value for t
Returns void
Inherited from AbstractPath.setStartTValue
- Defined in sims/roller/AbstractPath.ts:106

toString

toString(): string
Returns string
Inherit Doc
Inherited from AbstractPath.toString
- Defined in sims/roller/AbstractPath.ts:47

x_func

x_func(t): number
Returns the x value for the given value of t in the parametric equation.
Parameters
- t: number
  the value of t in the parametric equation
Returns number
the x value for the given value of t
Implementation of ParametricPath.x_func
Overrides AbstractPath.x_func
- Defined in sims/roller/SpiralPath.ts:73

y_func

y_func(t): number
Returns the y value for the given value of t in the parametric equation.
Parameters
- t: number
  the value of t in the parametric equation
Returns number
the y value for the given value of t
Implementation of ParametricPath.y_func
Overrides AbstractPath.y_func
- Defined in sims/roller/SpiralPath.ts:94
