Detailed Description

This class implements the a basic movement behaviour: it is possible to define the direction and the speed of the linear movement thanks to a TCL command in which the user has to define the destination point an the speed of the movement required. NOTE: the destination point is used to define the direction od the node and when it is reached the node will proceed for the same direction

Member Function Documentation

double BMPosition::getX

(

)

[virtual]

Method that return the current projection of the node on the x-axis. If it's necessary (updating time ia expired), update the position values before returns it.

Reimplemented from Position.

Definition at line 103 of file bmposition.cc.

References lastUpdateTime_, trgTime_, update(), and Position::x_.

Here is the call graph for this function:

double BMPosition::getY

(

)

[virtual]

Method that return the current projection of the node on the y-axis. If it's necessary (updating time ia expired), update the position values before returns it.

Reimplemented from Position.

Definition at line 111 of file bmposition.cc.

References lastUpdateTime_, trgTime_, update(), and Position::y_.

Here is the call graph for this function:

int BMPosition::command	(	int	argc,
		const char *const *	argv
	)			[virtual]

TCL command interpreter setdest <integer value>integer value>integer value>: set the movement pattern: the firts two values define the point to be reached (i.e., the direction of the movement) and the third value defines the speed to be used

Moreover it inherits all the OTcl method of Position

Parameters:

	argc	number of arguments in argv
	argv	array of strings which are the comand parameters (Note that argv[0] is the name of the object)

Returns:

TCL_OK or TCL_ERROR whether the command has been dispatched succesfully or no

Reimplemented from Position.

Definition at line 55 of file bmposition.cc.

Here is the call graph for this function:

void BMPosition::update

(

double

now

)

[private]

Method that updates both the position coordinates
