Function Documentation
◆ sfListener_getDirection()
| sfVector3f sfListener_getDirection | ( | void | ) |
Get the current forward vector of the listener in the scene.
- Returns
- Listener's forward vector (not normalized)
◆ sfListener_getGlobalVolume()
| float sfListener_getGlobalVolume | ( | void | ) |
Get the current value of the global volume.
- Returns
- Current global volume, in the range [0, 100]
◆ sfListener_getPosition()
| sfVector3f sfListener_getPosition | ( | void | ) |
Get the current position of the listener in the scene.
- Returns
- The listener's position
◆ sfListener_getUpVector()
| sfVector3f sfListener_getUpVector | ( | void | ) |
Get the current upward vector of the listener in the scene.
- Returns
- Listener's upward vector (not normalized)
◆ sfListener_setDirection()
| void sfListener_setDirection | ( | sfVector3f | direction | ) |
Set the orientation of the forward vector in the scene.
The direction (also called "at vector") is the vector pointing forward from the listener's perspective. Together with the up vector, it defines the 3D orientation of the listener in the scene. The direction vector doesn't have to be normalized. The default listener's direction is (0, 0, -1).
- Parameters
-
direction New listener's direction
◆ sfListener_setGlobalVolume()
| void sfListener_setGlobalVolume | ( | float | volume | ) |
Change the global volume of all the sounds and musics.
The volume is a number between 0 and 100; it is combined with the individual volume of each sound / music. The default value for the volume is 100 (maximum).
- Parameters
-
volume New global volume, in the range [0, 100]
◆ sfListener_setPosition()
| void sfListener_setPosition | ( | sfVector3f | position | ) |
Set the position of the listener in the scene.
The default listener's position is (0, 0, 0).
- Parameters
-
position New position of the listener
◆ sfListener_setUpVector()
| void sfListener_setUpVector | ( | sfVector3f | upVector | ) |
Set the upward vector of the listener in the scene.
The up vector is the vector that points upward from the listener's perspective. Together with the direction, it defines the 3D orientation of the listener in the scene. The up vector doesn't have to be normalized. The default listener's up vector is (0, 1, 0). It is usually not necessary to change it, especially in 2D scenarios.
- Parameters
-
upVector New listener's up vector
