Rotating Vertically

[Fern]

Hi, All

Using EOD I can make an object rotate horizontally (radar antenna), of course.

But how do I make something rotate vertically, such as a windmill? I asked around and I got some interesting replies, related to editing the api directly. Unfortunately, the replies only gave partial information.

Ideally I'd see the entire api of a very simple object, like a cube, that could rotate vertically.

If anyone out there knows how to do it, and is willing to make a cube with EOD, make it rotate vertically and show (or send, e-mail address below) me the api, I can look at the api and see what makes it rotate vertically and apply the info to other objects.

I know it is asking a lot, but the two apis (one that rotates and the one that doesn't) would be just fantastic. Any other info you might have such as what funny code means what (such as "2" means "dusk" and "dawn", geezz), like angles of axis of rotation, etc. will me greatly appreciated.

As I want to learn rather than have the windmill, a cube is just about perfect for the lesson, I think.

I rather not use gmax for this.

Thanks, All!

Hi Fern,

I don't use EOD, so maybe it is easier if you post a simple API macro here. The I can show you where to add the commands to rotate it.

Rotating wind mill

Hi Arno

Ok, here it goes. This is the API of a rectangular box some 12 m in length, not very thick, and about 2 m wide. The box is representing the blade of a windmill, although it really doesn't belong to any scenery object, it is just a sample.

Now, something that occurred to me just now... When something rotates it has to have a pivot, and the pivot has to have a location...

So, if you go through the trouble of making ir rotate, don't forget to tell me how the pivot gets to be located in the object...

Perhaps you can add comments to each line you add. But remember, I am just scratching the surface with this SCASM BGLC stuff, and I need more info than the more advanced fellows... Sorry...

Thanks, Arno!!!

Here is the api:
