Ok, Hello my name's ArTh4$ and i will show how to make an elevator for new mappers.

 -First you make your own elevator , when you have it just make in the 2d view script brush model click on N    targetname / elevator

-Then put in the elevator or near it, a trigger can be use touch if u want click on F and it moves , multiple when u come near it moves , damage when u shot it moves.. what ever

-And end click on N and put in the trigger entity  targetname/ trig_elevator

I give here the script save it as mp_elevator.gsc

main()
{
thread elevator();
}

elevator()
{
elevator=getent("elevator","targetname");
trig=getent("trig_elevator","targetname");
while(1)
{
trig waittill ("trigger");
elevator movez (-250,7,1.9,1.9);
elevator waittill ("movedone");
wait(1);
elevator movez (250,7,1.9,5);
elevator waittill ("movedone");
}
}

If you want it comes down just change the -  down like this:

main()
{
thread elevator();
}

elevator()
{
elevator=getent("elevator","targetname");
trig=getent("trig_elevator","targetname");
while(1)
{
trig waittill ("trigger");
elevator movez (250,7,1.9,1.9);
elevator waittill ("movedone");
wait(1);
elevator movez (-250,7,1.9,5);
elevator waittill ("movedone");
}
}

For load it in your mapname.gsc add this line

maps\mp\mp_elevator::main();

 Have fun making your own elevator^^  if you have a question or whatever just ask me ^^
