TranslucentLine woes

[CO2]

Alright, I'm a bit (see: very) confused here. The wiki says

Code: Select all

208:TranslucentLine (lineid, amount, additive?, moreflags)

The zdoom_udmf.txt file says:

Code: Select all

   Some specials also allow setting the extended flags. These must also be
   converted to explicitly setting the flags through the defined map fields.
   This affects the following specials:
   
   121: Line_SetIdentification, arg1
   208: TranslucentLine, arg2

So is arg2 additive or is it the extended flags?

I'm not sure if this is what you mean, but you don't need to use any specials to achieve translucency in UDMF. Just select the line, click the "Translucent" check box, and then under custom, change the alpha. 0.5 is half translucent.

...
TranslucentLine(3,125,1);

That work perfectly!

Note to the uninformed: He's writing a Hexen to UDMF map converter!

Ooops, typo. Should mean arg3, of course.

On another note, the wiki says to scrap arg0 on TranslucentLine after converting, but the spec says not to.

Edit: And the spec never said anything about the tag high byte for line_setidentification, am I supposed to convert it too?
