Well, maybe something else is wrong, and btw, why do you need a trigger for a function that it's also server side..?
addEventHandler('onColShapeHit', Col,
function(hitElement, dim)
if getElementType(hitElement) == "player" then
if getTeamName(getPlayerTeam(hitElement))=="Police" then
moveObject(Barrier, 1000, 1544.69, -1630.8, 13.3, 0, -90, 0)
playSoundFrontEnd (hitElement, 5)
end
end
end
)
