Browser Interface
The browser object provides a script with means to get information from the browser as well as performing actions which affect your world, or even replace it.
The following table presents a list of the methods available for the browser object ( see data types for an explanation of the return values):
| Return value | Method name | Description |
| SFString | getName() | Returns the name of the browser |
| SFString | getVersion() | Returns the version |
| SFFloat | getCurrentSpeed() | The speed at which the viewpoint is moving in meters per second, 0.0 is returned if this function is not implemented |
| SFFloat | getCurrentFrameRate() | The current frame rate in frames per second, 0.0 if not implemented. |
| SFString | getWorldURL() | Returns the URL of the root of the current world. |
| void | replaceWorld(MFNode nodes) | Replaces the current world with the world represented by the list of nodes passed as an argument. |
| void | loadURL(MFString url,MFString parameters) | Loads the url specified with the parameters argument. The paramenters syntax is as defined in the Anchor node. You can load an url into a different frame using the TARGET parameter. |
| void | setDescription(SFString descritpion) | Sets the description for the current world. The display of the description is browser dependent. |
| MFNode | createVrmlFromString(SFString vrmlSyntax) | This method constructs the nodes described in the string and returns the corresponding VRML scene. |
| void | createVrmlFromURL(MFString url, SFNode node, SFString event) | Loads the url and sends the event event to the node specified with the loaded nodes. |
| void | addRoute(SFNode fromNode, SFString eventOut, SFNode toNode, SFString eventIn) | Creates the following ROUTE:
ROUTE fromNode.eventOut TO toNode.eventIn |
| void | deleteRoute(SFNode fromNode, SFString eventOut, SFNode toNode, SFString eventIn) | Deletes the specified ROUTE:
ROUTE fromNode.eventOut TO toNode.eventIn |
Examples using the Browser Script Interface:
Loading More Stuff (source code)
- When the user clicks the geometry it replaces the current world using loadUrl
- Changing the contents of a frame using Proximity Sensors and loadUrl
- Uses getName, getVersion, getCurrentSpeed, getCurrentFrameRate,getWorldURL plus a Script to display the information.
Creating VRML from a string (source code)
- When the user presses the geometry nodes are added to the current scene
