I've recently been learnin stringtable and description files and it aint bin to easy but I think I can help. You dont need titletext to be able to do this.
If you look in the stringtable of snYpers mission op axe-point(damn good mission btw!) he has the following
STRM_nothing, " ",
then in the description
class CfgSounds
{
sounds[] = {nothing, d1conv1, d1conv2, d2conv1, d2conv2, d2conv3, d2conv4, d2conv5, d2conv6, d3conv1, d3conv2, d3conv3, d3conv4, d2convEnd1};
class nothing
{
name = "";
sound[] = {};
titles[] =
{
0, $STRM_nothing
};
};
and then in the intro file
Alpha_Officer say "d1conv2"
~4
HQ_Officer say "nothing"
so 4 seconds after the Alpha_officer has said "d1conv2" the text will fade off the screen.
hope this will have been of some help to you m8 (if not iv wasted my time and urs lol!)
