Question Velcro rockets Size parameter

[Wolfer]

I'm just wondering what it's for. Whenever I change it nothing happens once Orbiter is loaded and there doesn't seem to be an explanation in the manual.

Here's an example:

; === Configuration file for vessel class Shuttle Tank ===

Module = Velcro
Meshname = Atlantis_tank
Size = 17.0

Mass = 35425.0 ; empty mass [kg]
MaxFuel = 719115.0 ; max fuel mass [kg]
Isp = 1.0 ; fuel specific impulse [m/s]
IspSL = 1.0

MaxMainThrust = 0
MaxRetroThrust = 0
MaxHoverThrust = 0
MaxAttitudeThrust = 0
COG_OverGround = 4.0
CameraOffset = 0.0 .865 -2.5
CW = .2 .3 .7 .7
LiftFactor = 0.0
CrossSections = 400.0 400.0 94.0
RotResistance = 0.7 0.7 0.3
Touchdownpoints = 0 4.4 -7.53 4.4 0 -7.53 -4.4 0 -7.53

; === Attachment specs ===
BEGIN_ATTACHMENT
C 0.0 0.0 8.16 0 0 1 0 1 0 VELCRO1
C -0.543 0.0 0.0 0 0 1 1 0 0 VELCRO2
P 0.0 0.0 8.16 0 0 1 0 1 0 VELCRO3
P -0.543 0.0 0.0 0 0 1 1 0 0 VELCRO4
END_ATTACHMENT

That's just the Orbiter-standard Size parameter. It's a radius, in meters, of the object mesh, used purely to minimize clipping. Any .cfg-based vessel will set the Size.

Velcro also uses it to position the attitude jets and apply the rotational force at jettison, but that's a minor detail.

Could you configure this to add a rotating attachment point to a vehicle to accept a pair of thrusters, such as the V-22 except with rockets instead of rotors?

 

[sputnik]

Donamy,

No, I don't see how. Velcro Rockets attaches only once; there's no provision for rotating an attach point, nor dynamic updating of thrusters attached to same. The only way I know of to do what you ask is with a custom .dll, such as the Shuttle-A uses. It's probably the best way to control the pods, anyway.

 

[Wolfer]

So how does one go about changing the size of a stage?

 

[Donamy]

Thanks for clarifying.

 

[sputnik]

Wolfer,

If you want to change the size of the mesh, you have to change the mesh itself.

 

[Wolfer]

Ah ok, thanks.
