Creating a portal elevator

Introduction

It is a common misconception that making a elevator in portal is very hard. It is, however a very simple process. If it is created properly, it can be turned into a prefab and easily duplicated.

The Base

The first thing to do is to build the base for the elevator. This consists of brushes and func details. It is the fastest part of the process.

The Landing

Step 1

A landing is really easy to make. It consists of 7 walls and a floor and ceiling with a similar hole.
It can be easily recreated from the image on the right.

When you have finished your first landing, texture it and group it, so it can be easily duplicated for the bottom landing.

The Shaft

Step 2

The shaft is also very easy. It consists of 3 parts. A top cap, a middle piece, and a bottom cap.
Walls are 192*16, and textured with plasticwall002a.

The caps are 64 units tall, and the center piece is 384 units.

The Shaft Details

Step 3

• 1. Create 4 16*16 sized brushes and place them in each corner. They should be turned into a func_detail.
  
• 2. Next, create a block that is 8*8*160.

Texture it with plasticwall002a as well.

Then slice it into 3 pieces vertically, that are 2, 4, and 2 respectively.

Take the center piece and resize it to be 2 units wide, instead of 8. Texture it with white008.

Duplicate this piece to from a square.

Make it a func_detail and place one every 64 units in the center shaft.

The Landing Details

Step 4

Place the elevator landing prop in the center of the landing.
You may choose to add the 16 light beams, however for such a time consuming process, it is easier to copy it from the example map.
Note: All original portal maps have a misplaced light beam. If copying it, you may wish to move it into place.
Place the platform rings in place. The top of these rings align to the top of the platform room.

Copy the landing details to the second landing.

The Elevator

The Props

Step 5

Place a prop_dynamic with these settings in the lower landing.

Property Name	Value
Name	elevator1_model
Parent	elevator1_train
World Model	models/props/round_elevator_body.mdl

The TrackTrain

Step 6

Hide world details and make a func_tracktrain out of invisible brushes as shown.

Property Name	Value
Change Angles	None
First Stop Target	elevator1_path1
Height Above Track	0
Max Speed	65
Name	elevator1_train
Stop Sound	eli_lab.elevator_stop
Volume	1

Check every flag except Fixed Orient, and Use Max Speed. Set these settings:

The CrazyBlock

Step 7

Create an invisible brush and place it as shown. This will stop a player from getting stuck in the door when collisions are enabled.

Property Name	Value
Name	elevator1_block
Parent	elevator1_train
Start Disabled	Yes

The Paths

Step 8

Place two paths in the center of the room. Call the first one elevator1_path1, and the second one elevator1_path2. Do not set the second path to point to anything.

Enable props and test the map using ent_fire. Determine if the paths need to be repositioned. In my case I needed to move it back 8 units and down 16.

The Details

Beams

Step 9

Place an info_particle_system with the following values:

Property Name	Value
Name	elevator1_beam
Parent	elevator1_train
Particle System Name	elevator_beam
Start Active	Yes

Place an env_citidel_energy_core with these settings:

Property Name	Value
Name	elevator1_core
Parent	elevator1_train

Lights

Step 10

Place two env_lights with the following settings:

Property Name	Value
Name	elevator1_lights
Appearence	Slow strobe
Brightness	183 204 218 60
Brightness HDR	183 204 218 40

Also, set initially dark.

Sounds

Step 11

Place three sounds, with their source set to the elevator model. They should be:

• Portal.elevator_chime
• Portal.elevator_start
• Doors.FullClose11

Name them something unique.

Shake

Add an env_shake with these settings:

Property Name	Value
Duration	2
Name	elevator1_shake
Parent	elevator1_train

The Trigger

Create a trigger brush inside the elevator with these outputs:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnTrigger	elevator1_doors	SetAnimation	close	0.00	No
	OnTrigger	elevator1_block	Enable		0.00	No
	OnTrigger	elevator1_train	StartForward		5.00	No
	OnTrigger	elevator1_start	PlaySound		5.00	No
	OnTrigger	elevator1_shake	StartShake		5.00	No
	OnTrigger	elevator1_lights	TurnOn		8.00	No

Set the second path track to have these outputs:

	My Output	Target Entity	Target Input	Parameter	Delay	Only Once
	OnTrigger	elevator1_shake	StartShake		0.00	No
	OnTrigger	elevator1_close	PlaySound		0.00	No
	OnTrigger	elevator1_lights	TurnOff		0.00	No
	OnTrigger	elevator1_chime	PlaySound		1.00	No
	OnTrigger	elevator1_doors	SetAnimation	open	1.00	No
	OnTrigger	elevator1_block	Disable		1.50	No

Final Touches

Place a soundscape (portal_testchmb.elevator_shaft) in the center of the shaft.
You may add a changelevel, which fires with the path_track. Change levels will not be covered in this tutorial.

Note: You should save the elevator in its own file and copy and paste it to preserve the grouping, so you can easily turn it into a multi stop elevator.

To make a multiple stop elevator, simply add another path track, and set the middle path tracks to fire a stop event to the train. A trigger can be placed at every floor and disabled until required.
