Advanced Question attachment-Grappling point arrows for RMS

[Interceptor]

HI,I was wondering if someone could tell me what to change in the config to get the blue,and red arrows to appear after pressing Lshift+Num5, so far I can only get the black arrow to show up at the end of the spacecraft3 RMS.Thanks

Which shuttle ?

Not a shuttle just a spacecraft3 RMS arm, I put together,just fooling around trying to understand attachments in SC3.Thanks

Thanks for the info Notebook,but I have already read your posts,about SC3,thou I just read something about the child attachment ID has to start with a G,I think I tried that already,and no go.HMMMM!

Yes, I've just re-read it, and can't understand any of it! It was a long tiime ago, thats my excuse...

I can't remember any problems getting the red/blue arrows to appear, setting the TIP paramaters was tricky, lots of winging it there.

I'll have another look at the .cfg fiiles, and see if inspiration turns up.

[CONFIG]
MESHNAME="spacecraft\A_Frame"
SIZE=9.
EMPTY_MASS=1000
COG=0.18

[PARENT_ATTACH_0]
NAME="rms"
POS=(0, 2.65, 3.4)
DIR=(0, 0, -1)
ROT=(1,0, 0)
RANGE=3
LOOSE=1

[ROBOTIC_ARM]
JOINT_0_NAME="A_FramePitch"
JOINT_0_SEQ=0
JOINT_0_RANGE=(0,1)
GRAP_SEQ=0
GRAP_ATTACH=0

; A_FramePitch
[ANIM_SEQ_0]
INIT_POS=0
DURATION=10

;A_FramePitch : This is the grapple point motion
[ANIM_COMP_0]
SEQ=0
TIP_1=(0,2.65,3.4)
TIP_2=(0,2.65,-3.4)
TIP_3=(0,2.85,3.4)
ROT_PNT=(0, 0.15, 0)
ROT_AXIS=(1, 0, 0)
ANGLE=-90

;A_FramePitch : This is the A_Frame meshes animation
[ANIM_COMP_1]
SEQ=0
GROUPS=1,2,3,4,5,6,7,8,9,10,11,12
RANGE=(0,1)
ROT_PNT=(0, 0.15, 0)
ROT_AXIS=(1,0,0)
ANGLE=-90

This is the simplest one, may help?

Thanks again Notebook.:thumbup:

Youre welcome Interceptor. I see some of the link in the other thread are missing, must have moved the target!

This may help to show what I was trying to do:

It shows the Blue Streak rocket attached to its Handling_Frame, brought up to the A_Frame, dropped, re-attached. Then the A_Frame RMS grabs the Handling_Frame and rotates to the vertical.

This is what its part of:

I think the tricky part of the RMS grapple and movement was remembering that the mesh and the RMS are seperate.
Took a while to realise that just because there was a RMS as part of the A_Frame .cfg, the TIP had to animated as well as the mesh. Well, thats how I think of it.
