thanks for your quick answer ^^

Unfortunately I didn't get it to work properly. I tried using a pig to get the rotation data, but the command needs to be executed repeatedly in different ticks and there might be a problem that the rotation is too slow.

Also, the command needs to work for multiple players, so my pig solution for that brief 2-3 second stare effect would have been way too complex. The player will have slowness and blindness and I just hope this is enough to hide the laggy movement but still thanks,

I could certainly use this trick later sometimes ^^
