Basic Elevator Author: Brian Lozier

This tutor focuses on creating a simple elevator that goes up (or down) when you step on it. Elevators controlled by switches will be covered in a later tutorial.

1. We are going to create a 2x2 elevator, at floor level of the default sector, that goes down a shaft to another room. The first thing I always do when I'm working with numbers is space the grid to 0.1. Whenever I do that, I also snap the grid to 0.1.

2. Now, we switch to surface mode and cleave a 2x2 square out of one of the corners. Don't worry, it's easy! Just follow the dots and cleave like shown below.



3. Now extrude that surface, so it creates a tube going down from the floor. The tube will fit the elevator perfectly if you cleaved the dimesions right. If you are using Jed Beta 5, you will have to extend the tube as shown below, but Jed Beta 3 usually makes it long enough.



4. Now it's time to put the elevator "thing" in. To do this, just switch to the "thing" mode, and press [insert]. Then, with the new thing selected, press [return] to bring up the Item Editor Window. Now, in the top box, you can double click to bring up a window that lets you choose what item it is. Choose the 2x2elev.

5. Okay, now switch the grid snap to 0.05. This will allow you to perfectly place the elevator where it needs to be.

6. Now position the elevator just below the top of the tube. Make sure to check from the top view and the side view to make sure you placed it correctly.

This is the 3D preview of Jed Beta 5. Notice that the top of the elevator is just below the floor.

7. Now it's time to start making that elevator work! With the elevator selected, again press [enter] to bring up the Item Editor. You will notice, at the bottom of the Item Editor, a button called "Add Value." We are going to get very familiar with that button. When you click on it the first time, it will come up with a box asking you what "value" you'd like to add. The first time, it should already be filled in with "THINGFLAGS" (no quotes).

8. Fill that value in with "0x400048" (no quotes). Most of the time, this is already filled in also, just double check it.



9. Now, add 3 more values using the "Add Value" button. Call the first one "Numframes" the second and third call "frame"



10. In the "numframes" box, enter the number 2.

11. The two "frame" boxes are for the starting point and ending point of the elevator. They will contain coordinates of the level. The first one is the starting point, i.e. where the elevator is now. The easiest way to get the coords is to make sure the elevator is selected, and press the "copy as frame" button in the Item Editor. This will copy the coords into memory. All you have to do to get them in the 1st "frame" box is right click in it, and click "paste"



12. Now, the first "frame" was very easy. The second one is a little bit harder, but not too hard, so don't worry. Like I said, the first "frame" is where the elevator starts. The second "frame" is where it is going. The easiest way, in my opinion, to get this value, is to just add another elevator, exactly where you want your elevator to end up. Then, after we get the new elevator's coords, we just delete it.

13. To do this, insert your new elevator with the [insert] key, and position it where you want your elevator to end up. Make sure to check it's position from all views. Remember to position it just ABOVE the floor of the shaft.



14. Now, with the temporary elevator selected, press [enter] to bring up the Item Editor. Now press "Copy As Frame" to record the coords in memory.

15. Now, go to your original elevator, bring up the Item Editor, and paste the coords from the temporary elevator into the second "frame" box.



16. Now, you can delete the temporary elevator.

17. It is now time for the COG. It is not very difficult, and once you learn it and do it a couple of times, it won't be anything at all. First of all, go to the "Tools" menu, and click on "Placed Cogs." Then, press the button "Add COG." When you are presented a list, choose "00_std_elev.cog"

18. This cog has a few values that we will be adding.



19. First of all, I am going to define what the various values are:

Value	Description
lower_adjoin0 (surface)	This will define one of the surfaces the player must walk over to activate the elevator.
lower_adjoin1 (surface)	This is the same thing as "lower_adjoin1 (surface)," except you can add another surface.
elevator (thing)	This is the Thing Number. When the Thing is selected, this number is displayed at the top of the Item Editor.
start_wait (flex)	This is the amount of time the elevator waits before it starts to go up or down. You can experiment with this later, I'm not going to mess with it.
sleeptime (flex)	This is the amount of time the elevator stays at its destination. Again, I'm not going to mess with it.
speed (flex)	This is how fast the elevator travels. I am going to leave this alone also.

20. Okay, first put in the "thing number." In my case it's "1."

Now we are going to discuss how to get both the "adjoin" numbers. As I said before, these numbers will define a surface, and when a player walks over this surface, the elevator will go up. To make sense, it must create the illusion that when the player steps on the elevator, it goes up. To do this, we put values for the two surfaces surrounding our elevator.

1. There is no really easy way to do this. First, you have to cleave the original sector to extend the tube up into the room. Note that this will not be visible to the player, as all surfaces will be adjoined. Cleave the original sector as shown below.



2. Now you have to select the surface that the player must walk over to activate the elevator. Refer to the following diagram.



3. If you press [enter] while this surface is selected, it will bring up the Item Editor. At the top of the Item Editor, it will display the sector and surface number. Take note of this for the next step.

4. In the first "adjoin" box of the Placed Cogs window, enter the sector and surface number separated by a space. In my case, as shown below, it is Sector 3, Surface 0.



5. Now to get the second value. Select the other surface as shown below.



6. Place the Sector and Surface numbers in the second "adjoin" box.



7. That's it! Now your elevator should work! Just save/gob your file, and test it out.

I realize that this elevator brings you down a tube, and then strait back up, but I assume you can create a room at the bottom. If not, refer to my tutorial on adjoining. Apply what you have learned!

Note: If you want your elevator to be in the center of a room, and want it to work the same way, then there is an extra step. I created mine along a corner because it is easier that way.

The only thing you have to do is add another Cog, the same one as before. In this new cog, add the two other surfaces that the player can walk over to activate the elevator. (there will be 4 now, because it's not against a wall, and each cog will only accept 2) Also remember to add the Thing Number, or it won't work.
