Hi,

The header contains the min and max coordinates of the entire scenery, so you need to make sure it is big enough to fit your runway. Same for the latrange.

The area number does not matter that much. The different area types have a different maximum size, but with only a runway you will not get a big BGL anyway.

See the SCASM documentation for all details:

I tried this, but without succes
how or in what kind of program do i find these numbers (ADE, Google earth?, or something)
now i struggling with this scasm method and still without succes, and now I feel myself like a dumbass
I have attached my runway notepad and ADE BGL for WADD airport, can you take a look at it?
Thanks

Linden

Hi,

Did you actually look at the SCASM documentation? It should you that the header has 5 arguments, not only two:

So based on your runway latitude and longitude (I assume these are OK), I would try something like this:

Code:
``````Header( 1 -8.7 -8.8 115.2 115.1 )
LatRange( -8.8 -8.7 )

Area( 5 -8.748330474 115.167459995 )
LayerCall( :drawStuff 52 ) ; main call, let's draw stuff
Jump32( : ) ; finished now, get outta here

:drawStuff
Runway( -8.748330474 115.167459995``````

Thanks Arno, it works

You're right about the 5 arguments,
I am now in the learning fase for SCASM, but it's very difficult for me, because my mathematics are very bad, on school it was the difficultest lesson of all lessons for me,
I have searched some information about the DD:MM:SS.SSSS on the internet
and what i think to understand is, that there are needed some calculations?
correct me if i'm wrong.
Can you give me a step to step explanation about how to do these 5 arguments, and what kind of programs ( if needed) i need for it?
because it seems to be great, if i can learn this too.
Thanks Arno
