WorldExternBase Class

Members

int getClassID ( ) #

Return value

Node getNode ( ) #

Return value

WorldExtern getWorldExtern ( ) #

Return value

int loadWorld ( Xml xml ) #

Arguments

• Xml xml - Xml smart pointer.

Return value

void preRender ( float ifps ) #

Arguments

• float ifps - Inverse FPS value.

void renderHandler ( ) #

void renderVisualizer ( ) #

int saveState ( Stream stream ) #

Saving into the stream requires creating a blob to save into. To restore the saved state the restoreState() method is used:

// initialize a node and set its state
//...//

// save state
Blob blob_state = new Blob();
worldExtern1.saveState(blob_state);

// change state
//...//

// restore state
blob_state.seekSet(0); // returning the carriage to the start of the blob
worldExtern1.restoreState(blob_state);

Arguments

• Stream stream - Stream smart pointer.

Return value

int restoreState ( Stream stream ) #

Restoring from the stream requires creating a blob to save into and saving the state using the saveState() method:

// initialize a node and set its state
//...//

// save state
Blob blob_state = new Blob();
worldExtern1.saveState(blob_state);

// change state
//...//

// restore state
blob_state.seekSet(0); // returning the carriage to the start of the blob
worldExtern1.restoreState(blob_state);

Arguments

• Stream stream - Stream smart pointer.

Return value

int saveWorld ( Xml xml ) #

Arguments

• Xml xml - Xml smart pointer.

Return value

void update ( float ifps ) #

Arguments

• float ifps - Inverse FPS value.

void updateEnabled ( ) #

void updatePosition ( ) #

void updateTransform ( ) #

void setUpdateDistanceLimit ( float distance ) #

Arguments

• float distance - Distance from the camera within which the external world should be updated (in units).

float getUpdateDistanceLimit ( ) #

Return value

void setUpdate ( bool enabled ) #

Arguments

• bool enabled - true to enable forced updating for the external world; false - to disable forced updating and take the update distance into account.

bool isUpdate ( ) #

Return value
