LookAndMoveTool Class

A tool that performs the walk operation using mouse+keyboard or touch controls. Keyboard and mouse controls are similar to those used by many video games:

  • Mouse motion: look around.
  • W, A, S, D (or arrow keys): move forward, left, right, or backward respectively.
  • E, Q (or PgUp, PgDn): move up and down respectively.
  • +, - (or scroll wheel): increase or decrease velocity.

Inherited properties

Name Type Inherited from Description
description Accessor ReadOnly string ViewManip Get the localized description string from this Tool's class
description Accessor StaticReadOnly string ViewManip Get the localized description for this Tool class. This returns the value of "tools." + this.toolId + ".description" from
its registered Namespace (e.g. "en/MyApp.json"). If that key is not in the localization namespace,
ViewManip.flyover is returned.
englishKeyin Accessor StaticReadOnly string ViewManip Get the English keyin string for this Tool class. This returns the value of "tools." + this.toolId + ".keyin" from
its registered Namespace (e.g. "en/MyApp.json").
flyover Accessor ReadOnly string ViewManip Get the localized flyover string from this Tool's class
flyover Accessor StaticReadOnly string ViewManip Get the localized flyover for this Tool class. This returns the value of "tools." + this.toolId + ".flyover" from
its registered Namespace (e.g. "en/MyApp.json"). If that key is not in the localization namespace,
ViewManip.keyin is returned.
frustumValid boolean ViewManip  
handleMask number ViewManip  
hidden Static boolean ViewManip If true, this Tool will not appear in the list from ToolRegistry.getToolList.
i18n Static I18N ViewManip The internationalization services instance used to translate strings from the namespace.
iconSpec Accessor ReadOnly string ViewManip Get the iconSpec from this Tool's class.
inDynamicUpdate boolean ViewManip  
inHandleModify boolean ViewManip  
isControlDown Accessor ReadOnly boolean ViewManip Convenience method to check whether control key is currently down without needing a button event.
isDragging boolean ViewManip  
isDraggingRequired boolean ViewManip  
isDynamicsStarted Accessor ReadOnly boolean ViewManip Call to find out if dynamics are currently active.
isZUp Accessor ReadOnly boolean ViewManip  
keyin Accessor ReadOnly string ViewManip Get the localized keyin string from this Tool's class
keyin Accessor StaticReadOnly string ViewManip Get the localized keyin string for this Tool class. This returns the value of "tools." + this.toolId + ".keyin" from
its registered Namespace (e.g. "en/MyApp.json").
maxArgs Accessor StaticReadOnly undefined | number ViewManip The maximum number of arguments allowed by ViewManip.parseAndRun, or undefined if there is no maximum.
If subclasses override ViewManip.parseAndRun, they should also override this method to indicate the maximum
number of arguments their implementation expects.
minArgs Accessor StaticReadOnly number ViewManip The minimum number of arguments allowed by ViewManip.parseAndRun. If subclasses override ViewManip.parseAndRun, they should also
override this method to indicate the minimum number of arguments their implementation expects. UI controls can use
this information to ensure the tool has enough information to execute.
namespace Static I18NNamespace ViewManip The I18NNamespace that provides localized strings for this Tool.
nPts number ViewManip  
oneShot boolean ViewManip  
receivedDownEvent boolean ViewManip Used to avoid sending tools up events for which they did not receive the down event.
targetCenterLocked boolean ViewManip  
targetCenterValid boolean ViewManip  
targetCenterWorld Readonly Point3d ViewManip  
toolId Accessor ReadOnly string ViewManip Get the toolId string for this Tool class. This string is used to identify the Tool in the ToolRegistry and is used to localize
