So if i have a 3d floor above a non 3d floor and   place   linedef for player to walk over it doesn't recognize the line ontop 3d floor?

I'd check it out, tell me what you learn.

linedefs are a 2D concept, heights are not checked when a player walks over them to trigger something.

If you need to trigger something on a specific 3D floor, it must be done another way, e.g. with an ACS script.

How about if the line you're walking over is part of a 3d sector and not just a single linedef? 

 

As already mentioned, a walkover linedef spans the height of a sector.

What you can do, however, is use a function like GetActorFloorZ to specify

the z value of a floor as in this script utilizing a jumppad triggered on

a 128 high 3D floor, triggered from the front only

#include "zcommon.acs"

 

script 2 (void)
{
   if (GetActorFloorZ (0) >= 128)
      {
         if(lineside() == LINE_FRONT)
         {
              // 128:ThrustThingZ (tid, force, up=0/down=1, set/add);
            ThrustThingZ (0, 200, 0, 0);
         }
      }
}

         }
      }
}

 

 

This code will not work as expected because GetActorFloorZ returns a fixed point value, so you have to compare it to fixed point values, in this case for example to 128.0.

@boris

Do you mean

if (GetActorFloorZ (0) >= 128.0)

instead of

if (GetActorFloorZ (0) >= 128)

?

In my case, both work.

128.0 is the correct way. Using just 128 will trigger the if statement's body when the player z position is higher than about 0.001953 map units.

I cracked it! I placed a non 3d floor outside dummy sector then gave it same tag as 3d floor inside eg.5 then made them both have same floor ceiling heights and wala
