float getForwardSpeed | ( | ) |
Returns the speed of full forward motion, when the mouse is at the very top of the window.
This is in units (e.g. feet) per second.
float getH | ( | ) |
float getHorizontalDeadZone | ( | ) |
Returns the size of the vertical bar in the center of the screen that represents the "dead zone" of horizontal motion: the region in which the mouse does not report horizontal motion.
This is in a fraction of the window width, so 0.5 will set a dead zone as large as half the screen.
float getHorizontalRampDownTime | ( | ) |
Returns the amount of time, in seconds, it takes between the time a left or right arrow key is released and the time it registers no motion.
float getHorizontalRampUpTime | ( | ) |
Returns the amount of time, in seconds, it takes between the time a left or right arrow key is pressed and the time it registers full rotation.
const LVecBase3 getHpr | ( | ) |
Returns the driver's orientation.
bool getIgnoreMouse | ( | ) |
Returns the current setting of the ignore_mouse flag.
See set_ignore_mouse().
const LMatrix4 getMat | ( | ) |
Returns the current transform.
float getP | ( | ) |
const LPoint3 getPos | ( | ) |
Returns the driver's position.
float getR | ( | ) |
float getReverseSpeed | ( | ) |
Returns the speed of full reverse motion, when the mouse is at the very bottom of the window.
This is in units (e.g. feet) per second.
float getRotateSpeed | ( | ) |
Returns the maximum rate at which the user can rotate left or right, when the mouse is at the very edge of the window.
This is in degrees per second.
float getRotSpeed | ( | ) |
Returns the rot_speed of the previous update in units/sec.
float getSpeed | ( | ) |
Returns the speed of the previous update in units/sec.
bool getStopThisFrame | ( | ) |
Returns the current setting of the stop_this_frame flag.
See set_stop_this_frame().
float getVerticalDeadZone | ( | ) |
Returns the size of the horizontal bar in the center of the screen that represents the "dead zone" of vertical motion: the region in which the mouse does not report vertical motion.
This is in a fraction of the window height, so 0.5 will set a dead zone as large as half the screen.
float getVerticalRampDownTime | ( | ) |
Returns the amount of time, in seconds, it takes between the time an up or down arrow key is released and the time it registers no motion.
float getVerticalRampUpTime | ( | ) |
Returns the amount of time, in seconds, it takes between the time an up or down arrow key is pressed and the time it registers full forward or backward motion.
float getX | ( | ) |
float getY | ( | ) |
float getZ | ( | ) |
reset | ( | ) |
Reinitializes the driver to the origin and resets any knowledge about buttons being held down.
setForceMouse | ( | bool | force_mouse | ) |
Changes the state of the force_mouse flag.
If this flag is true, the mouse button need not be held down in order to drive the avatar around.
setForceRoll | ( | float | force_roll | ) |
This function is no longer used and does nothing.
It will be removed soon.
setForwardSpeed | ( | float | speed | ) |
Sets the speed of full forward motion, when the mouse is at the very top of the window.
This is in units (e.g. feet) per second.
setH | ( | float | h | ) |
setHorizontalDeadZone | ( | float | zone | ) |
Sets the size of the vertical bar in the center of the screen that represents the "dead zone" of horizontal motion: the region in which the mouse does not report horizontal motion.
This is in a fraction of the window width, so 0.5 will set a dead zone as large as half the screen.
setHorizontalRampDownTime | ( | float | ramp_down_time | ) |
Sets the amount of time, in seconds, it takes between the time a left or right arrow key is released and the time it registers no motion.
setHorizontalRampUpTime | ( | float | ramp_up_time | ) |
Sets the amount of time, in seconds, it takes between the time a left or right arrow key is pressed and the time it registers full rotation.
setHpr | ( | const LVecBase3 | hpr | ) |
Directly sets the driver's orientation.
setHpr | ( | float | h, |
float | p, | ||
float | r | ||
) |
setIgnoreMouse | ( | bool | ignore_mouse | ) |
Changes the state of the ignore_mouse flag.
If this flag is true, the DriveInterface will ignore mouse down button events (but still recognize mouse up button events); the user will not be able to start the DriveInterface going again if it is stopped, but if the user is currently holding down a mouse button it will not stop immediately until the user eventually releases the button.
setMat | ( | const LMatrix4 | mat | ) |
Stores the indicated transform in the DriveInterface.
setP | ( | float | p | ) |
setPos | ( | const LVecBase3 | vec | ) |
Directly sets the driver's position.
setPos | ( | float | x, |
float | y, | ||
float | z | ||
) |
setR | ( | float | r | ) |
setReverseSpeed | ( | float | speed | ) |
Sets the speed of full reverse motion, when the mouse is at the very bottom of the window.
This is in units (e.g. feet) per second.
setRotateSpeed | ( | float | speed | ) |
Sets the maximum rate at which the user can rotate left or right, when the mouse is at the very edge of the window.
This is in degrees per second.
setStopThisFrame | ( | bool | stop_this_frame | ) |
If stop_this_frame is true, the next time the frame is computed no motion will be allowed, and then the flag is reset to false.
This can be used to prevent too much movement when we know a long time has artificially elapsed, for instance when we take a screenshot, without munging the clock for everything else.
setVerticalDeadZone | ( | float | zone | ) |
Sets the size of the horizontal bar in the center of the screen that represents the "dead zone" of vertical motion: the region in which the mouse does not report vertical motion.
This is in a fraction of the window height, so 0.5 will set a dead zone as large as half the screen.
setVerticalRampDownTime | ( | float | ramp_down_time | ) |
Sets the amount of time, in seconds, it takes between the time an up or down arrow key is released and the time it registers no motion.
setVerticalRampUpTime | ( | float | ramp_up_time | ) |
Sets the amount of time, in seconds, it takes between the time an up or down arrow key is pressed and the time it registers full forward or backward motion.
setX | ( | float | x | ) |
setY | ( | float | y | ) |
setZ | ( | float | z | ) |
