use a delaygoto command in script and the enter (envir/mapquest) trigger for kr.
To make everyone on a map leave after a certain time use mapting (eg #act mapting 1 0 - moves everyone on map 1 to map 0 in random place, or specify place #act mapting 1 0 168 235).
If you want to just move one person use mapmove, if a group use groupmove command - #act groupmove map xx yy range %username
ps. time for delays is counted in seconds.
