UDMF question on linedef properties

[Zhadoom]

Hello!

Pardon my ignorance, but I havn*t yet quite figured out what the following properties for linedefs in the UDMF format are made for:

Jump over railing
Clip middle texture
Wrap middle texture
Wakable middle texture

Where can I read "more detail" on these topics?

Thanks

Check the specs, here: https://github.com/rheit/zdoom/blob/mas ... _zdoom.txt

Thanks, Blue Shadow!

But... uhm, what does this mean:

Actors can walk on mid texture.

How can an actor walk on a texture?

It means, simply, when you put a midtex up in the air (you'll have to adjust your offsets) - the actor will clip to the midtex itself like a thin 3D floor.

This was done way back in the day to make walkable bridges, except obviously you could see through them.

Hi Eruanna!

Ah okay, so you're saying that this property is obsolete due to the availability of real 3d floors in recent ports?

No. It is still very useful to make fences and similar stuff.
This originates from Eternity, but the reason to add it to ZDoom was the desire to have a more general implementation of Strife's railing flag.
