Settings in This Example:

• Pause game while message is displayed - if checked this will halt the gameplay until the window is closed. This may be needed if you have a long introductory HTML information page, otherwise leave unchecked.
• Close previous message popup windows - checked is usually a good idea unless you want multiple message windows open.
• Message location: - the Top left of the screen has been chosen as the location for the message window. Other positions are Top right, Bottom left and Bottom right.
• The web page to be displayed is named "right_away.html" and the sound file to be played is named "all-aboard.wav". Both are found in the HTML asset named General Purpose Session HTML
• Autoplay Wav is ticked so the sound will be played when the page is displayed.

Notes:

• If you are creating your own HTML file then knowledge of HTML, as used by TANE, will be required.
• The HTML file (with filename extension ".html") must be in a Trainz asset of type HTML.
• Graphics and a limited set of HTML effects are possible.
• The sound file settings HTML Wave and Wave Name are optional.
• If a sound file is to be played when the message is displayed then it must be of type WAV (with filename extension ".wav") and must be in a Trainz asset of type HTML. It does not have to be in the same HTML asset as the HTML page.

Settings in This Example:

• Gameplay will not be paused while the message is displayed.
• Any previously opened message window will be closed before this message is displayed.
• Message location: - the Top left of the screen will be used.
• A Custom Message, as entered into the text box, and a selected Icon will be displayed.
• No optional sound has been added.

Notes:

• No knowledge of HTML is required.
• You are limited to about 6 lines of text.
• Text only can be entered.
• You can select and display an optional icon with the message.

• the config.txt file of the HTML asset must have a string-table container which holds all the text messages to be displayed.
• the string-table token is the "tag" which identifies the message text in the config.txt file.

For example, the config.txt file of the asset General Purpose Session HTML contains the following:-

string-table
    {
        html_warning_late       "You are running late!"
    }

...which will produce the message "You are running late!" from the Message Popup Rule settings shown on the left.
