For the flashpoint title screen you just need
titleRsc ["Flashpoint", "PLAIN"]
I can't remember the names of the others, but I think you can make them appear from a trigger.
If you want your own, then first make the image and put it in your mission folder. Then define it in description.ext
For example:
class RscTitles
{
class naughty2
{
idd=-1;
movingEnable=0;
duration=8;
name="naughty2";
controls[]={"Title"};
class Title: RscPicture
{
text="naughty2.jpg";
x=0.300000;
y=0.000000;
w=0.500000;
h=1.000000;
};
};
};
And use
titleRsc ["naughty2","plain",0.1]
when you want it. There is a tutorial somewhere because I used it, though I can't remember where.
