Question going sideways!

[pilotpercy]

ive been messing around, trying to understand how to use "spacecraft 3" and i have been using a very simple mesh to test things out.

im having problems getting the spacecraft to fly upwards! no matter which "DIR" i put in (ive tried -1 and +1 on all axis) the rocket just seems to move forward scraping along the floor.

also i cannot get any exaust to come out in any direction. i even tried copying the exhaust ini from the delta glider and still nothing.

any ideas??

In Orbiter, when looking forward (toward the nose from the aft end of the ship), axes are as follows:

+X = right (i.e., starboard), -X = left (i.e., port)
+Y = up, -Y = down
+Z = forward (toward the nose), -Z = aft (toward the tail)

There are two sets of coordinates involved when defining a thruster: 1) the thruster's location relative to the center of mass, and 2) the thruster's direction as a vector. Location is specified in a set of X/Y/Z coordinates, like this:

-4.488, 0, -10.254

The first number in the example is X, and means that the thruster is 4.488 meters to the LEFT (or port) of the center of mass in the "left/right" dimension. The second number, Y, is zero which means it is directly on the centerline of the ship's mass in the "up/down" dimension. The third number, Z, means that the thruster is 10.254 meters AFT of the center of mass in the "front/back" dimension.

The second set of numbers is the vector that the thruster pushes. For main engines that push the ship forward the vector is:

0, 0, 1

The Z value of '1' means that the thruster pushes FORWARD along the Z axis. A value of -1 would mean that the thruster would push AFT along the Z axis, like a retrorocket.

The same principals apply to hover thrusters as well: a direction of (0, 1, 0) means that the thruster pushes the ship up (+Y axis). You will want to be sure to always create your hover thrusters in pairs to keep the ship balanced while hovering. For example:

Forward hover thruster coordinates: (0, 0, 10)
Aft hover thruster coordinates (0, 0, -10)

Direction for both hover thrusters would be the same: (0, 1, 0)

Thruster exhausts are specified the same way as thrusters are: 1) location, and 2) direction

And in Spacecraft 3 no matter how you define your thrusters, Main engines will always push the ship +Z and hovers will always push the ship +Y.

In other words, you need to spin your mesh.

KK, ive spun my mesh but now, whenever i start a scenario the rocket is on its side, nomatter what i put as the landing and launch points??????

and still no exhaust textures!

In scenario file put CONFIGURATION 0 if you have launch point.

 

[pilotpercy]

launch point? you mean like a tower?there is no tower i just copied the landing points and launch points text from another spacecrafts file and changed the points accourdingly. do you think this coud be the source of my problem?

 

[liber]

Just upload file here and all would be easy to se what's wrong...but here in my add you got 2 ini file so you could see what's for landing and launching point.

the spacecraft is called tin and i have hover and main in the same vector atm to test if either worked.

I mean you could attach to post add-on,with mesh,scenario and ini...maybe mesh need to be rotate or see what's with scenario file.

You are only copy this or edit?

LAUNCH_PT1=(0,0,0)
LAUNCH_PT2=(0,0,15.6)
LAUNCH_PT3=(7.8,0,7.8)
LAUNCH_PT4=(-7.8,0,7.8)
LAND_PT1=(0,0,0)
LAND_PT2=(0,0,15.6)
LAND_PT3=(7.8,0,7.8)
LAND_PT4=(-7.8,0,7.8)

i edited that to fit my mesh. im trying to fiddle with axis now and i have gotten rid of the launch points.

if my mesh is on its side in anim8or, will it always appear sideways in orbiter no mater what i put as its landing points?

 

[liber]

When exporting to mesh converter this is proper turn,view from side...plane nose is up...

 

[pilotpercy]

nope, still nothing, i turned it the corret way up and left its nose poking out of the ground the tried increasing the landing points in the y axis but this had no effect.


-----Post Added-----


just found something interseting. nothing i do in the config/spacecraft/tin file does anything.

i just set the camera to (0,300,300) and set the landing points all to (0,0,0) and nothing changed!!

if i can work out why this is i can work out what the origional problem is.

any ideas???
