Code classes:

env_message is a point entity present in all Source games. It draws a text message on player HUDs, from strings defined in the /scripts/titles.txt file. It's used at some points in Hl2.png, such as when the player's buggy falls into water.

Syntax[edit | edit source]

Each message entry in titles.txt follows a similar structure as other Valve text files. Example: Title { Text Value }. The message can reference a localized string prefixed with #.

This text can be formatted in many different ways, according to the syntax provided. The resource/clientscheme.res is responsible for the font family, size and weight of the message. To change the size find CenterPrintText in the res file.

Variables can be defined which will affect all the messages below them, until overwritten with another value.

Variable Parameters Description
$position float, float Position of the text onscreen. First float is horizontal, second is vertical. -1 is centered
$effect integer How it is displayed. 0 is fade in/fade out, 1 is flickery credits, 2 is write out
$fxtime float The amount of time the highlight lags behind the leading edge of the text
$color R G B Color of the text as red blue green between 0-255
$fadein float Fade in time of message or each character in seconds
$fadeout float Fade out time in seconds
$holdtime float How long to wait after fade in before fade out

If you're making a mod you can alter this file with your own entries. The default titles from HL2 are listed below:
