Portal Level Creation

Introduction

In this tutorial you will learn how to create a 1500-Megawatt Aperture Science Heavy-Duty Supercolliding Superbutton which when stepped on or weighted down with a box will open a specified door.

The door setup

First thing is to make the door which will open on activation of the button.

Door frame

Create a prop_static in your door way. The World Model should be set to "models/props/door_01_frame_reference.mdl" or "models/props/door_01_frame_wide_reference.mdl" (either one works).

Doors

How to align the func_door.

1. Create a prop_dynamic with the following settings:

Property Name Value
World Model models/props/door_01_lftdoor_reference.mdl
Name door_left_model

Align it to the left, inside of the door frame.

2. Create a 56Lx8Wx104H block brush with texture nodraw centered and inside the door model. Tie it to a func_door entity by selecting the object and using the menu option "Tie to Entity". The func_door entity should have the following settings:

Property Name Value
Name door_left
Speed 250
Stop Sound Doors.FullClose8
Delay before Reset -1
Lip 12
Move Direction (This will be different for which way your door is facing)

Also make sure that you un-check Touch opens under Flags.

The best way to ensure you have the correct Move Direction is to first mark the direction on the circular indicator, then round to the nearest 90 degrees (so long as your doors are intended to be square with the Hammer coordinate system). You can click the "Point At" button by the circular indicator and then click on the 3d view. The angle from the entity to the place you clicked will then be listed as "angles" in the property list.

Note:You can also put a blocking damage if you don't want the player to get stuck inside it. Also, you can turn on Forced Closed for it to close even if the player tried to jam it open with a camera or cube.
Final door.

3. Repeat steps 1-3 but change the following: For the prop_dynamic:

Property Name Value
World Model models/props/door_01_rtdoor_reference.mdl
Name door_right_model

And for the func_door:

Property Name Value
Name door_right
Move Direction (The opposite of the move direction for the left door)

4. Set the parent of door_left_model (the prop_dynamic) to "door_left". Also set the parent of door_right_model to "door_right".

The button

Models

How to align the button models.

1. Create a prop_static with a World Model of "models/props/button_base_reference.mdl".

2. Create a prop_dynamic aligned on top of the prop_static with the following settings:

Property Name Value
World Model models/props/button_top_reference.mdl
Name button_top_model

Movement

1. Next create a 58Wx58Lx9H cylinder brush with 8 sides and textured with nodraw. Move this brush right underneath your prop_dynamic. Tie the cylinder to a func_door with the following settings:

Property Name Value
Name button_top_door
Speed 25
Delay before Reset -1
Move Direction 90 0 0 (or Down)

Also make sure nothing is checked under Flags.

2. Set the Parent of button_top_model to be "button_top_door".

Triggers

The larger trigger_multiple.

1. Create a 48Wx48Lx1H block brush with trigger texture applied. Place it right on top of the button_top_model. Tie this brush to a trigger_multiple with the following settings:

Property Name Value
Name button_trigger_player

We will set up the Output later. Also make sure to only have the flag: Client set.

The smaller trigger_multiple.

2. Next create a 7Wx7Lx1H cylinder brush with 8 sides and textured with trigger texture applied. Put this brush directly on top and in the center of the button_top_model and tie it to a trigger_multiple with the following settings:

Property Name Value
Name button_trigger_box

And only the following Flags are checked:

  • Physics Objects

We will set up the Output later.

3. Create a filter_activator_name nearby your button with the following settings:

Property Name Value
Name button_filter_boxes
Filter Name (The name your box entity has)

4. Select your button_trigger_box trigger and set the Filter Name to "button_filter_boxes".

5. Create two ambient_generic entities and give one the following settings:

Property Name Value
Name button_down
Sound Name Portal.button_down
Source Entity Name button_top_model

and the other with

Property Name Value
Name button_up
Sound Name Portal.button_up
Source Entity Name button_top_model

6. Now go back and select the cylinder func_door brush under the button, "button_top_door" and setup the Outputs as below:

My Output Target Entity Target Input Parameter Delay Only Once
Io11.png OnClose door_left Close <none> 0.00 No
Io11.png OnClose door_right Close <none> 0.00 No
Io11.png OnClose button_up PlaySound <none> 0.00 No
Io11.png OnOpen door_left Open <none> 0.00 No
Io11.png OnOpen door_right Open <none> 0.00 No
Io11.png OnOpen button_down PlaySound <none> 0.00 No

7. Select the larger trigger_multiple, "button_trigger_player" and setup the Output as below:

My Output Target Entity Target Input Parameter Delay Only Once
Io11.png OnEndTouchAll button_trigger_box Enable <none> 0.00 No
Io11.png OnEndTouchAll button_top_door Close <none> 0.00 No
Io11.png OnStartTouch button_trigger_box Disable <none> 0.00 No
Io11.png OnStartTouch button_top_door Open <none> 0.00 No

8. Select the smaller, cylinder trigger_multiple, "button_trigger_box" and setup the Output as below:

My Output Target Entity Target Input Parameter Delay Only Once
Io11.png OnEndTouchAll button_trigger_player Enable <none> 0.00 No
Io11.png OnEndTouchAll button_top_door Close <none> 0.00 No
Io11.png OnStartTouch button_trigger_player Disable <none> 0.00 No
Io11.png OnStartTouch button_top_door Open <none> 0.00 No
The final product.

9. Finally, create a light entity underneath the top of the button but still inside the base. Give it the following properties:

Property Name Value
Brightness 251 159 57 30
BrightnessHDR 251 159 57 20
Note:The light should be 2 Units above the original base ground that the main base Button model is on, in order to cast correctly.

You have now created a button which will open a door by a player standing on the button or a box weighing it down. Only those two things will work on it.

Making a hole in the wall

While this step is optional, and your door may be fully functional without it, your map will look especially awkward if you just have a door in the middle of a space, and even more so if you have walls around it to block the player before opening the door. This step is simple enough, so it is recommended that you try it out.

Clipping the hole

Do not carve the hole for the door. Always use the clipping tool. Make a 128 by 128 block around the door.

Using the clip tool, trace the outline of the door frame. Make sure not to leave gaps that aren't covered up by the door frame.

Once you have cut around the door frame, delete the part that is blocking the door. Select the rest of the brush left behind, and click the "to entity" button to turn it into a func_detail.

You now have a hole that the door can fit into, and can be easily placed into any map.

The theory

This is the most basic button and door setup. You can also have the triggers turn off or on other things in the map, have them trigger a logic_choreographed_scene or just about anything. For the Portal feel you can have them trigger Indicator Lights based on the button up or down status.

If you do decide to use Indicator Lights, then make sure to have the func_door (The Nodraw cylinder) Set Outputs when it closes, and opens. When it opens, set the texture Index to 1, and when it closes, set the texture index to 0, via a env_texturetoggle that controls the lights.
