Hi Tonino
I made something just like this just abit ago. Transportifused does work, just need to change alittle. Setup your two trigger zones. Give this to your "IN" trigger zone.
:state=0,plrwithinzone=1:state=1
:state=1,scancodekeypressed=33:sound=$0,video=YOUR VIDEO PATH HERE,stopsound=$0,state=2
:state=2,plrwithinzone=1:state=3,plrsound=SOUND PATH IF NEEDED,plrmoveifused
:state=3,plrwithinzone=0:state=4
Give your OUT trigger a unique name and place in ifused of "IN" trigger.Should work,tested.
Also, the player should be given some onscreen display to press "F".
