Turns the current view of a VR movie one step at the specified direction.
Parameter movieRef is the reference to the movie instance. The movie reference must have been previously obtained with a call to QM_NewMovieFromFile or QM_NewMovieFromURL. The movie must be currently assigned to a movie plug-in area.
Parameter nudgeDirection specifies the direction of the nudge.
QMedia defines the following constants for specifying nudge directions:
| qm_VRNudgeRight | 0 | Nudge right |
| qm_VRNudgeUpRight | 45 | Nudge up-right |
| qm_VRNudgeUp | 90 | Nudge up |
| qm_VRNudgeUpLeft | 135 | Nudge up-left |
| qm_VRNudgeLeft | 180 | Nudge left |
| qm_VRNudgeDownLeft | 225 | Nudge down-left |
| qm_VRNudgeDown | 270 | Nudge down |
| qm_VRNudgeDownRight | 315 | Nudge down right |
Note: QM_Nudge only accepts one of the directions listed above. It will not react to any other value.
Example
`Nudge VR movie $movie to up-right $err:=QM_Nudge ($movie;qm_VRNudgeUpRight) |
