Discussion: lift (elevator)

Well, this is the first script that I have written that I think might be worth something to someone else. There isn't much to it, but I was trying to figure out a creative way to get from one level to the next with out walking. I hope you like it, and I am sorry if it is already out there and I missed it.

 
 // lift script, v 1.0 by timeless montreal
 //
 // This script will allow you to make any prim a lift or an elevator.
 // You should only have to change the liftAmount to the distance 
 // you want the lift to move. Of course, if you rather it move
 // side to side, it shouldn't be too hard to tweak.
 //
 // enjoy!
 
 integer liftAmount = 4; // change this to the amount you 
 								   // want to go up/down
 
 integer isUp = FALSE; // Stores whether the object is up
 
 
 movePlatform(){	
 	llStartAnimation("stand");
 	if(isUp == FALSE){
 		llSetPos(llGetPos() + <0, 0, liftAmount>);
 		isUp = TRUE;
 	} else {
 		llSetPos(llGetPos() + <0, 0, -1*(liftAmount)>);
 		isUp = FALSE;
 	}
 }
 
 default
 {
 	state_entry()
 	{
 		llSitTarget(<0,0,1>,<0,0,0,1>);		
 		llSetSitText("Lift");
 	}
 	
 	
 	changed(integer change)
 	{
 		if(change & CHANGED_LINK)
 		{
 			key avataronsittarget = llAvatarOnSitTarget();
 			if( avataronsittarget != NULL_KEY ) 
 			{
 				if ((llGetPermissions() & PERMISSION_TRIGGER_ANIMATION) && llGetPermissionsKey() == avataronsittarget) {
 					llStopAnimation("sit");
 					movePlatform();
 				} else {
 					llRequestPermissions(avataronsittarget, PERMISSION_TRIGGER_ANIMATION);
 				}
 			}
 		}
 	}
 
 
 	run_time_permissions(integer perm)
 	{
 		if(perm)
 		{
 			// Place the code here!
 			llStopAnimation("sit");
 			movePlatform();				
 		}
 	}
 }
 
 
 

You may want to program in some reference position, either up or down, as repeated use might make this elevator "walk".

I was looking for something like this since I don't have enough room in my house for a set of stairs. I'll try it out and let you know how it works for me.
Thanks!

The easiest thing to do when you don't have room for stairs is to just have a short-range teleporter.

All you would need to do is add a panel to the wall with a script that just has something similar to this:

vector FloorTwo = <0,0,5>; //This is for how far away the desired location on the second floor is from the button the script is in
default
{
	state_entry()
	{
		llSetText("Click to go to the 2nd floor",<1,1,1>,1>;
		llSitTarget(FloorTwo,ZERO_ROTATION);
	}
	changed(integer change)
	{
		if (CHANGE & CHANGED_LINK)
		{
			key av = llAvatarOnSitTarget();
			if (av)
			{
				 llSleep(0.5);
				 llUnSit(av);
			}
		}
	}
}

Now obviously I just threw that together, but it operates on the same principle, only it moves you instead of the prim/object. Really just the most basic of a sit teleport script. I would just imagine that if there's no room for stairs, there probably isn't much room for an elevator

Course this all assumes that you are saying that even the single prim spiral stairs that can be made with rings and tubes are too large.

what is the maxium height that you can go up and down?

300 M limit on any axis

I tried combining a little of both the above scripts and ot works to move myself upstairs, but I tried to tweak it to move me back down and I keep getting syntax errors at every math symbol I try. It then sends me farther up instead of down.
Here's the code:

liftAmount = 5; //This is for how far away the desired location on the second floor is from the button the script is in
default
{
state_entry()
{
llSetText("Click to go to the 2nd floor",<1,1,1>,1);
llTouchTarget(llSetPos(llGetPos() - <0, 0, liftAmount>;
}
changed(integer change)
{
if (change & CHANGED_LINK)
{
key av = llAvatarOnTouchTarget();
if (av)
{
llSleep(0.5);
llUnSit(av);
}
}
}
}



I'm a total newbie to LSL but have some experience in other languages, so I may be way off base.
What am I doing wrong?

1. You should have decleard your "liftAmount" as float.
2. There is no llTouchTarget function. It must be llSitTarget.
3. llSitTarget requires a vector and a rotation as parameters.
4. llSetPos doesn't return anything.
5. There is no llAvatarOnTouchTarget function. It must be llAvatarOnSitTarget.

I think it can go up to 768m height.

I just did some experiments using a box with a simple teleport script and it certainly stopped me going above 300 M above the box. When I selected 330 M it put me at 300 M above the box.

I then tilted the box in one axis by 45 degrees, and I was able to get 400M up.

with formula "target- llGetPos()) / llGetRot()" it still went up at right angles to the ground. I guess Pythagoras has something to do with that. With one tilt you should be able to go to the square root of 180000 (300 * 300 + 300 * 300) which I make to be a bit above 400. If you tilt in another direction as well you could possibly get another 100 M or so, probably giving you a total of over 500 M, still a bit short of 768.

Its close to midnight for me, so my brain is turning into mush. Maybe someone can calculate what the actual theoretical limit is.

I guess that because they are tilted, tp's are usually orbs so it will not be so noticable!

ed44, the point seems to be that whose script FDSpark asked about. You took it was Tiarnalalon's short-range teleport one and I took it was OP's lift one.
So what we should have told was that llSitTarget's limit was generally 300m (tricky 500m) and llSetPos's limit was 768m.

Well another limitation of llSetPos is you can't go any further than a 10m vector distance away from your current loc. So for example, if you wanted to move the elevator up 12m, it would fail.

Don't get me wrong, I like the nice feel of using an elevator to change floors, and I have one I made that works quite well non-physically....but it's more of a warpPos transporter than an elevator. I have have you sitting with a standing animation inside something that looks rather like a turbolift.

For a physical platform to use as an elevator and not have a ANY limitations to height (20,000 meters anyone?) you can scavenge parts from the script in this thread;
/54/80/148764/1.html

EDIT. It has been a while and I forgot but there are two useful scripts in that link. The first post is a physical vehicle and on the second page at the end there is an attachment. Both work well.

Sorry to confuse the issue. To make amends I'll summarize this thread, there are four ways to move around using aids:

a. wearing a prim containing a flight assist script. See:
/54/81/135024/1.html
I wear one of these in a little prim on my back and moved it inside my av's body.

b. sitting on a prim and having it move you and itself around. There is a 10 M single move limit but Keknehv Psaltery overcame this and developed warpPos which you can see at:
http://rpgstats.com/wiki/index.php?title=LibraryWarpPos

c. changing the sit target of a prim up to 300 m in any axis direction and then sitting on that prim. See post #5.

d. using a physical elevator. Really needs Havok 2. You would not need to sit on this, but an animation override is desirable. Jesse has described this.

Hope I did not add more to the confusion.

Someone on another recent thread added a 5th way.. that I just checked out for myself. Sim "The Future" has a transport system that appears to be push-based. You walk through a prim and get pushed up and at certain points there are other prims that push you in a different direction when you collide. It's nice work but may not be suitable for all parcels.

Thanks. Always happy to learn more. The 5th way way seems like an extension of a flight assist script controlled by others.
