The information in this Wiki Page applies to TANE, TRS19 and Trainz Plus.

Message Popup Icons

	Message Popup Icons are small graphic icons that can be placed in browser message windows in Driver mode. The browser windows are created by the Message Popup Rule
	Message Popup Icons are classified as Non-Environmental Textures

Information on creating and using Message Popups can be found on the Trainz Wiki pages at:-

How to Create a New Non-Environmental Texture Asset

Steps

Create the Asset:

From the Trainz Launcher

select Manage Content
in Content Manager open the Developer menu
select New Content

This will create a new asset and open it for editing.

A message window will appear that will (hopefully) report on the successful creation of a new asset.

Close the message window

Find the New Asset:

Set the CM Search Filter to Open for Editing

This will display only those assets that have been opened for editing (hopefully only your new and as yet unnamed asset will be shown)

Open the Asset in Windows File Explorer:

Right mouse click on the entry New Asset
Select Open
Select Show in Explorer

Open Config.txt File in Notepad:

There will only be a single item in the asset, its config.txt file

Double click on the file to open it in Notepad

Edit the Config.txt File:

You will need to edit the contents of this file.

The next section, The Config.txt File, identifies the changes you will need to make.
The new name you give to the asset will not take effect until after it has been committed.
After editing, save the changes and exit Notepad.

Warning:
	Unless you know exactly what you are doing, DO NOT ALTER THE KUID NUMBER that has been added to the file but even if you do, think twice before you change it !

Add Any Extras:

You will need to add:-

a thumbnail image as described in the section The Thumbnail Image
the icon image as described in the section The Icon Image
a texture text file as described in the section The Texture File

These files do not have to be added immediately but must be present before the new asset can be used. You can reopen the asset for editing later to add the files before it is committed.

THIS IS AN EXAMPLE ONLY

This is the minimum number of files needed in a Texture asset

Finish Up:

Close the Asset window
Commit the asset in Content Manager
- Right mouse click on the asset
- Select Submit Edits

Hopefully there will be no errors.

Because you still have the Search Filter Open for Editing in operation, the now closed and Submitted asset will vanish from the Content Manager display. To check that your asset has been correctly created and renamed, set the Search Filter to Today.

Some of the most common errors that can occur when creating and committing a new asset are:-

no thumbnail image in the asset
typing errors in the config.txt file
poorly formatted tags in the config.txt file
incorrect file types added to the asset folder
files missing from the asset folder
incorrect kuid value (despite the warning you changed it in Step 5)

The Config.txt File

This file should follow the same (or a similar) format as the example below.

entries in red must not be changed
the indenting of the lines and the spacing ("tabbing") between the "tags" on the left and their contents on the right are purely to make it easier for humans to read
the use of the {} braces is to group tags into common "containers". These containers must not be broken up and the number of { characters must match the number of } characters
the order of the "tags" is not important

kuid                                    <kuid: this is an auto-generated number >
kind                                    "texture"
texture                                 "icon_gradeXing.texture"
username                                "icon grade crossing ahead"
category-class                          "JI"
trainz-build                            4.3

thumbnails
{
  Default
  {
    width                               240
    height                              180
    image                               "icon_gradeXing.jpg"
  }
  01
  {
    width                               64
    height                              64
    image                               "icon_gradeXing.texture"
  }
}
description             "Icon representing an approaching grade crossing. Designed for message popups."

Settings:

For the above example:

The kuid is unique to every asset so it is not a good idea to choose your own . This will be automatically generated by the Content Manager program when a new asset is created
The kind identifies the type of asset and the types of files that Trainz will expect to find in the asset. It also tells Trainz how to render and error check the asset. A list of asset kinds can be found at KIND Hierarchy
The texture is the name of the assets texture file. This will be a simple text file and will have the name asset_name.texture where asset_name will be a name you have selected for this asset - e.g. "icon_gradeXing". The actual texture file itself will be named asset_name.texture.txt (e.g. "icon_gradeXing.texture.txt") but the filename ending ".txt" is not added to the name in the texture tag so it would appear as "icon_gradeXing.texture"
The username is your name for the asset and the name that other users will see. It is a good idea to make it short and meaningful.
The category-class identifies the intent of the asset and is important in classifying it for filtering and searching. For texture icon assets, the category class is "JI". A list of category classes can be found at Category-class
The trainz-build identifies the minimum Trainz version needed for this asset. A list of asset trainz-build numbers and their corresponding Trainz versions can be found at "Trainz-build"_number
The thumbnails container holds the preview images of the asset shown by the Content Manager program, the Web version of the DLS and, for some assets, the Surveyor main menu image(s) and in this case the asset texture itself. Information on thumbnails can be found at Thumbnails
- The first thumbnail Default is the container ID or placeholder for the thumbnail used by CM and the Web based DLS. While its exact label (or number - eg. "Default", "00", "01", etc) is not important, it must be different from any other labels. Default and 0 are commonly used placeholder labels for the 240 x 180 thumbnail image
  - The image is the name of the thumbnail image. It does not have to be called thumbnail.jpg but it must be a JPG format image
  - The width of the image in pixels must be 240
  - The height of the image in pixels must be 180
- The second thumbnail 01 is the placeholder label for the 64 x 64 icon image used by the Message Popup Rule for this asset. Its exact label does not matter but it must be different from the first thumbnail image placeholder label
  - The image is the assets asset_name.texture.txt file (but without the ".txt" at the end)
  - The width of the image in pixels must be 64
  - The height of the image in pixels must be 64
The description provides more details for users than the username

	Language Options:
	All Trainz assets have a language facility built into their config.txt files that allows other language translations to be added for certain tags, such as the username and description tags. A full description of the process can be found on the Trainz Wiki at Localize an Asset and a list of all the supported languages with their two character codes at Localization (country) Codes. At the very basic level any creator can easily provide other language translations for the username and description tags in the assets they create. Examples are shown below for this sample asset.
username "icon grade crossing ahead" username-c2 "图标前方的路口" username-es "icono de cruce de grados por delante" username-fr "icône passage à niveau avant" username-gr "Symbol Bahnübergang voraus" username-nl "pictogram cijferovergang vooruit" username-ru "значок пересекает"
	Translations to Chinese (simplified), Spanish, French, German, Dutch and Russian, perfect or not, were provided by Google Translate.

The Thumbnail Image

A thumbnail image MUST be present in the asset. You can create a HTML asset without any other images but there must be a thumbnail image.

Notes:

The thumbnail image:-

must be in JPG format.
must be 240 pixels wide by 180 pixels tall.
does not have to be named thumbnail.jpg as long as the name used is in the Thumbnails container in the config.txt file.

The Icon Image

You will need image editing software to create the icon image or to change an existing image to the required dimensions and format.

(not to scale)

Settings:

The image must meet the following specifications:-

64 pixels wide and 64 pixels tall
bit depth should be 24 (no alpha channel or transparency) or 32 (if an alpha channel is used)
image file format can be any of:-
- bmp
- jpg (jpg does not support transparency)
- png
- tga (tga compression should not be used)

If your image will have a transparency, such as a transparent background, it is usually a lot easier to save the image in a format that supports an alpha channel (bmp, png or tga) and either

convert the background to a transparency or
remove the background and add a transparent layer to the image as its background

than it is to use a format that does not support an alpha channel and have to create a second image for the alpha channel. See

The Texture File below.

The Texture File

The .texture.txt file controls how an image icon is displayed, particularly its Alpha Channel (or transparency) data. The file must be present even if no transparency is used in the icon.


	Settings: the Texture File is a standard text file the filename is composed of:- a user selected asset_name followed by a period (.) the word texture followed by a period (.) the letters txt

A sample Texture File, "ashpit.texture.txt", is shown below:-

primary=ashpit.jpg
alpha=ashpit.bmp
tile=st


	Settings: primary - this is the name of the icon image file that contains the RGB colour image. Any alpha channel in this file will be ignored alpha - this is the name of the icon image file that contains the Alpha Channel (transparency) image (see Notes: below) tile=st - instructs Trainz to tile the image both horizontally and vertically. This has no effect on the icon in a message popup window but must be included for validation purposes No "white spaces" between the text characters is allowed.

Notes:

There are 3 general "scenarios" for the structure of the Texture File in a Texture Non Environmental asset.

If the icon has a transparency (an alpha channel) and is saved in a format that supports the alpha channel

Then:-

primary=ashpit.tga
alpha=ashpit.tga
tile=st

the primary and alpha images are the same file, as in the example shown left
the image must contain both the RGB colour data and the Alpha Channel (transparency) data (it must have a depth of 32 bits)

If the icon needs to have transparency (an alpha channel) but an alpha channel is not available (e.g. it is saved in the jpg file format) or is not suitable

Then:-

primary=ashpit.jpg
alpha=ashpit_alpha.jpg
tile=st

two different files (different file names or different image file formats) must be used as in the example shown left
both images must be the same size (64 pixels x 64 pixels)
both images must have a depth of 24 bits - so no alpha channel must be present in either image
the alpha image file should be a greyscale image or even just black and white

If the icon image does not have a transparency and no alpha channel is needed

Then:-

primary=ashpit.tga
tile=st

the alpha= line in the .texture.txt file is not needed, as in the example shown left
the primary file contains the RGB colour data and can be in any supported image format. If it also has alpha channel data then the alpha channel data will be ignored so the icon will be shown without any transparency

Image file formats supported by Trainz that have an alpha channel are:-

bmp
png
tga

Image file formats supported by Trainz that DO NOT have an alpha channel are:-

jpg

A detailed description of the .texture file format can be found on the Trainz Wiki Page at:-

Texture File

Using the Asset

Once the new asset has been committed it will be available for use in a Message Popup Rule. It will appear as a Texture Asset in the rule icon list.

Steps:

In the Session Editor add a Message Popup Rule and open it for editing.

Select Custom Text
Click the icon link Click here to set
Scroll through the list of Texture Icons
Select the required icon
Click the icon to accept the selection
