== Introduction ==
[[File:Train1.JPG|right|thumb|350px|Finished platform in [[Portal_Design_And_Detail|unfinished room]]]]
[[Image:Picture_03.jpg|right|Width:64]]
In this tutorial we will be creating a moving platform.


An example map is available for download [http://myfreefilehosting.com/f/c28a01c6bb_0.1MB here].
This tutorial covers the creation of a Scaffold in [[Portal]].


== Creating and setting basic model ==
You will need one from these models
*This one is bigger: <code> models/props/light_rail_platform.mdl </code>.
*This one is smaller <code> models/props/light_rail_platform_02.mdl </code>.
*After you make decided witch one is better for you, name it <code>platform_model</code>.
*Set its parent to <code>platform_func</code>, we will create it now.


== Creating function ==
Create brush with dimensions of chosen platform. It’s not nessesary, but it will surely work.
Tie it to <code>func_door</code> entity by presing [ctrl + t]. Set it’s variables as follow:


::{|
== The Platform ==
[[File:MovingPlatformTut1.PNG|right|thumb|200px|Properties for Step 1. Click to enlarge.]]
 
1. The first step is to insert the model of the platform. Create a [[prop_dynamic]] with the following settings:
:{| class=standard-table
!  Property Name || Value
|-
| World Model || models/props/light_rail_platform.mdl
|-
| Name || platform1_model
|-
| Parent || platform1_train
|}
[[File:MovingPlatformTut2.PNG|right|thumb|200px|Properties for Step 2. Click to enlarge.]]
 
2. The platform model does not have glass in it; this must be created manually. Create a brush that is 120x120x2 with the texture glass/glasswindow_frosted_004. Place it inside the platform model so that it lines up perfectly with the edges (you may need to set the grid scale to 2 or 1 temporarily). Tie it to a [[func_tracktrain]] with these settings:
:{| class=standard-table
!  Property Name || Value
!  Property Name || Value
|-
|-
| Change angles || this is up to you, I’m using: <code><b>never (fixed orientation)</b></code>
| Name || platform1_train
|-
| Height above track || 0
|-
| Change angles || never
|-
| Move sound || Portal.horizontal_lift_move
|-
| Volume || 2
|-
| Max pitch || 100
|-
| Min pitch || 80
|-
| First stop target || platform1_s1
|-
| Max speed || 40
|-
| Initial Speed || 40
|}
:Also, ensure no user control is checked.
[[File:MovingPlatformTut3.PNG|right|thumb|200px|Properties for Step 3. Click to enlarge.]]
 
3. To add an energy effect underneath the platform, create an [[env_citadel_energy_core]] [[point entity]], place it under the model, and set these values:
:{| class=standard-table
!  Property Name || Value
|-
|-
| Change velocity || too, it’s your choise, but: <code><b>ease in/ease out</b></code>
| Name || platform1_core
|-
|-
| First stop target || <code>P1_S1_M</code>      //P = path #, S = station #, M as Middle
| Parent || platform1_train
|-
|-
| Initial speed || <code>100</code>
| Pitch Yaw Roll || 90 0 0
|-
|-
| Initial speed || <code>100</code>
| Scale || .5
|}
:Set the flag to start on if desired.
 
== The Path ==

1. Create a [[path_track]], center it in the very center of platform1_train. This will be the starting waypoint for the path the platform follows. Set these values:
:{| class=standard-table
!  Property Name || Value
|-
| Name || platform1_s1
|-
| Next stop target || platform1_s2
|-
|-
| Name || platform_func
| Orientation type || no change
|}
:Set the flag teleport to this path_track if you have a one direction system.
 
:Also set these outputs:
 
::{| class=standard-table
!  || My Output || Target Entity || Target Input || Parameter || Delay || Only Once
|-
|-
| Max Rotation Speed || 30
| [[File:Io11.png]] || OnPass || platform1_train || Stop || 0 || 0 || No
|-
|-
|  
| [[File:Io11.png]] || OnPass || platform1_train || Resume || 0 || 1 || No
|}
|}
2. Create as many path_track entities as desired. Ensure they stay the same height, and follow the same numbers. Also make sure the last path_track 's keyvalue ''Next stop target'' points back to the first path_track if the platform is intended to travel in a loop.
3. Compile and test the map before continuing.
== The Energy Rail ==
{{More screenshots}}
1. Create a brush 12x2 and set it around the path. Texture it with effects/light_rail_beam1. Turn it to a [[func_brush]] with these settings:
:{| class=standard-table
!  Property Name || Value
|-
| Fx color || 225 252 253
|-
| Solidity || Never Solid
|}
2. Place [[info_target]]s at each bend or end of the rail brushes. The active energy rail beam effect will travel between these targets. Name them something like platform1_target1, platform1_target2, etc.
3. Create an [[env_beam]] for each straight section of track. Set the following:
:{| class=standard-table
!  Property Name || Value
|-
| Beam color || 38 50 68
|-
| Brightness || 255
|-
| Ending entity || (your info_target)
|-
| Life || 0
|-
| Name || platform1_beam
|-
| Render FX || Fast Wide Pulse
|-
| Sprite name || materials/Effects/laser1.vmt
|-
| Start entity || (your info_target)
|-
| Texture scroll rate || 2
|-
| Width || 4
|}
Set it to start on.
== Props ==
{{More screenshots}}
1. Add props at the end of the rails. Also under the corners. These decorative props will appear to be creating and directing the energy rail beam.
: Some props are :
:: models/props/light_rail_wall_emitter.mdl
:: models/props/light_rail_endcap.mdl
:: models/props/light_rail_corner.mdl
2. Add an [[env_citadel_energy_core]] that points at the base of the prop. Set these to start on with a scale of .5
== Enabling ==
1. To enable the train use these outputs:
::{| class=standard-table
!  || My Output || Target Entity || Target Input || Parameter || Delay ||  Only Once
|-
| [[File:Io11.png]] || OnTrigger || platform1_beam || Color || 176 217 247 || 0 || No
|-
| [[File:Io11.png]] || OnTrigger || platform1_beam || Width || 10 || 0 || No
|-
| [[File:Io11.png]] || OnTrigger || platform1_core || StartDischarge || 0 || 0 || No
|-
| [[File:Io11.png]] || OnTrigger || platform1_train || SetSpeed || 40 || 2 || No

This tutorial covers the creation of a Scaffold in Portal.


The Platform

Properties for Step 1. Click to enlarge.

1. The first step is to insert the model of the platform. Create a prop_dynamic with the following settings:

Property Name Value
World Model models/props/light_rail_platform.mdl
Name platform1_model
Parent platform1_train
Properties for Step 2. Click to enlarge.

2. The platform model does not have glass in it; this must be created manually. Create a brush that is 120x120x2 with the texture glass/glasswindow_frosted_004. Place it inside the platform model so that it lines up perfectly with the edges (you may need to set the grid scale to 2 or 1 temporarily). Tie it to a func_tracktrain with these settings:

Property Name Value

Height above track 0
Change angles never
Move sound Portal.horizontal_lift_move
Volume 2
Max pitch 100
Min pitch 80
First stop target platform1_s1
Max speed 40
Initial Speed 40
Also, ensure no user control is checked.
Properties for Step 3. Click to enlarge.

3. To add an energy effect underneath the platform, create an env_citadel_energy_core point entity, place it under the model, and set these values:

Property Name Value
Name platform1_core
Parent platform1_train
Pitch Yaw Roll 90 0 0
Scale .5
Set the flag to start on if desired.

The Path

1. Create a path_track, center it in the very center of platform1_train. This will be the starting waypoint for the path the platform follows. Set these values:

Property Name Value
Name platform1_s1
Next stop target platform1_s2
Orientation type no change
Set the flag teleport to this path_track if you have a one direction system.
Also set these outputs:
My Output Target Entity Target Input Parameter Delay Only Once
Io11.png OnPass platform1_train Stop 0 0 No
Io11.png OnPass platform1_train Resume 0 1 No

2. Create as many path_track entities as desired. Ensure they stay the same height, and follow the same numbers. Also make sure the last path_track 's keyvalue Next stop target points back to the first path_track if the platform is intended to travel in a loop.

3. Compile and test the map before continuing.
