Tutorial Frame by frame animations in Orbiter

[Arvil]

Wow! What stamina, doesn’t get tired.

 

[Fast_toche]

For these magnificent guys who made us dream!

 

[gamer19]

damn wish I have this in game
looks much better than the original

 

[kuddel]

The flexing of the PLSS however would make me nervous. ...is not what it should do!

 

[Fast_toche]

I'm making progress

 

[Fast_toche]

The Little Humans' Evening.

That's all well and good with the introductions, here's a little something I pulled out of my bag.

Tell me honestly what you think...

 

[gattispilot]

Do we need a cfg? and scn?

 

[Fast_toche]

Yes, I'm an idiot

You can do the scenario, but only in 2010 !

Tell me honestly what you think...

Long time since I fired up Orb10!
A .scn file would be nice. I used ScnEditer but it didn't work! It loads (is labeled with F9) but is invisible, log says "couldn't load .dll".

 

[Fast_toche]

Here's how to place a vessel in the desired location: Press F4, then Custom, then Scenario Editor, then New. Select the vessel, give it a name, and click Create. Then click Location, and finally Copy State From.

Here's a scenario, but it would be better to try it in the "Pictown" addon to see how the character moves relative to the environment.

For the commands:

case OAPI_KEY_S: if (down) { throttle_locked = false; boost_active = false; } return 1;

case OAPI_KEY_P:

I think your .dll may be compiled badly, are you sure it's compiled for Orbiter2010?

but it would be better to try it in the "Pictown" addon to see how the character moves relative to the environment.

Yes (is there a link?), or post a video?

 

[Fast_toche]

Here : https://www.orbiter-forum.com/resources/pictown-1-1.525/

Have you tried the scenario?

 

[Buck Rogers]

Have you tried the scenario?

I don't think that will make a difference? (can try anyway).

log says "couldn't load .dll"

As said I think it's a compile error?


Edit:
My Orbiter2010 install is so bloated it needs 10 min to load all the textures!

Same thing with the .scn file

Finished initialising world
---------------------------------------------------------------
>>> ERROR: Could not load vessel module: Nurse_Walk

Finished initialising status

 

[Fast_toche]

It's still strange that it works for me and many others too?

 

[Buck Rogers]

I tried it in Orbiter2016 and exactly the same thing. something is being loaded though, I can see the TD points working? Just that it is invisible.

 

[Fast_toche]

Essayez de vérifier ceci.

 

[Buck Rogers]

Sorry, same thing in both versions of Orbiter with the new .dll.
ERROR: Could not load vessel module: Nurse_Walk

 

[gattispilot]

It worked for me. But she seemed below the surface and was moving fast.
Maybe operator error.

When I press up key her arm moved. but no other keys to do any thing

 

[Fast_toche]

This doesn't work with Orbiter 2016! Only with Orbiter 2010.
B key: walk, run, other.
S key: stop.
P key: record trajectory.
O key: loop recording.
C key: delete recording.
Right key: turn right.
Left key: turn left.

Just a short test video:
