/*QUAKED game_text (1 0 0) (-8 -8 -8) (8 8 8) GTF_ALLPLAYERS
This entity displays a message of your choice on-screen.

-------- KEYS --------
"targetname" : Name
"message" : Text to display. Can be a titles.txt entry.
"x" : Horizontal position of text. (0 - 1.0 = left to right, -1 = center)
"y" : Vertical position of text. (0 - 1.0 = top to bottom, -1 = center)
"effect" : Effect to apply to the text. 0 : Fade In/Out; 1 : Credits; 2 : Scan Out
"color" : The main colour in RGB255.
"color2" : The highlight colour in RGB255.
"fadein" : Time taken to fade in each character.
"fadeout" : Time taken to fade out message.
"holdtime" : Length of time to hold message on screen after fading in.
"fxtime" : Time the highlight lags behind the leading edge of the text in seconds.
"channel" : Message channel to use. Meant for overriding messages.

-------- SPAWNFLAGS --------
GTF_ALLPLAYERS : Broadcast message to all players, not just the activator.

-------- NOTES --------
Line breaks inside "message" can be added with a \n character.

-------- TRIVIA --------
This entity was introduced in Half-Life (1998).
