HUD message

[Ra02]

I would like to know if it is possible to make a script that will trigger only from one side of the line, I want to make a script for each sector in my map but only when the player enters so only from one side, then a HUD message will appear telling his location, also what position for HUD message is center of the screen slightly below top. Thanks for reply's.

Depending on your requirement, you could use the hudmessage regular style or the hudmessage box style.
A problem may arise with overlapping text if a smaller screen resolution is selected.

Just play a bit with the x and y coordinates.


2. As to lineside read this http://zdoom.org/wiki/LineSide

ah, thanks a lot that is exactly what I was looking for

Edit: Not working as I wanted to, as I pass the line it triggers both lines, I created 2 lines near door, the one inside and one outside. But whenever I pass them they activate both.

I used this:


script 2 (int angle)
{
if (LineSide() == LINE_FRONT)
setfont("BIGFONT");
HUDMessage(s:"The Reception"; HUDMSG_FADEOUT, 0, 3, 0.5, 0.25, 0, 3.5);
}

Unfortunately, I have no clue what you want to achieve.

The best would be screenshots of the editor map layout and editor preview.
Or better still, send me a map of just the problem area
or publish it here for anyone else to help you.

Linedefs get triggered regardless what direction you walk over them, except for teleport linedefs. He wants his linedefs to work like teleport linedefs. He wants them to be triggered only from one side. For example, if you had a linedef with sidedef 1 facing east and sidedef 2 facing west, he would want it to be activated only when walking from west to east, not from east to west. But linedefs are activated regardless what direction you walk over them except for teleport linedefs. Simply put, he wants his linedefs to behave like teleport linedefs--they only work if you walk over them when the first sidedef is facing you.

exactly, so is that possible then?

}

The problem here is that you're missing curly braces.

The "if" conditional only affects the next instruction. So what happens is that the only difference between the front line and the back line is that from the back, the setfont call isn't run.

Try this:

script 2 (int angle)
{
    if (LineSide() == LINE_FRONT)
    {
        setfont("BIGFONT");
        HUDMessage(s:"The Reception"; HUDMSG_FADEOUT, 0, 3, 0.5, 0.25, 0, 3.5);
    }
}
