How do I temporarily prevent the player from moving around, say during a cutscene?
Could remove all player characters and re add them back in after the cutscene. . . I swear XP had a event to prevent players from moving, but I could be wrong, And I couldn't find anything in VXA. Having Events set to autorun will force the player to remain in place.
What maker are you using? VXA?
For VXA, there is an easy option to make the player transparent (as well as his party followers), which you could do during a cutscene (if you wish for the player to not be present during the scene).
And, as IAMFORTE said, they players shouldn't move during the cutscene if it's set to "autorun". I believe that they can move during most of the parallel processing commands, though. So, you'd want to avoid using those for awhile. They're a bit more complex. :irock2:
(It's hard to recall without actually looking at the maker. ;9)
Yanfly has a super tiny script to stop all movement (and select between the player, NPCs or both)
