Flightdeck Problem

S

stuart277

SOH-CM-2025
Hi All
I have been working on a Gmax model of an WWI Arethusa class light cruiser. The ships in this class were, apparently, the first ships to launch land based aircraft.
As such I have a model with a flying off platform over the forcastle of the ship, but when testing it in mission builder my aircraft start off sitting on the water and, of course, sink.
The cfg file is:
[fltsim.0]
title=Arethusa1913
sim=Arethusa1913
model=
panel=
sound=
texture=
checklists=
[flight_deck_section]
; this section defines the control points the
; AI (and LSO) use to steer towards the flight deck
width=10.25
length=131.25
takeoff_start=0,6.045,45.0
takeoff_stop=0,6.045,64.7
landing_start=0,500,-5000
landing_touch_down=0,6.045,45.0
landing_stop=0,6.045,62.0
　
[platform.0]
; platforms are the actual surface that the planes
; land on. You can define as many platforms as you
; want by adding subsequent sections with increasing
; numbers. e.g. [platform.1], [platform.2] etc.
;
; vertices should be defined in model coordinates,
; and counter-clockwise order when viewed from above.
: REMEMBER, positive z is out the TAIL of the ship
; the shape may be concave or convex
; there may be from 3 to 20 vertices (limitation
; may go away later) and they must all be on the same
; plane.
vertex.0=-1.267,6.045,64.701
vertex.1=1.267,6.045,64.701
vertex.2=4.335,6.045,46.46
vertex.3=-4.335,6.045,46.46

[LANDING AIDS]

[Dynamics]
pitch_wave_moment_scale = 3
bank_wave_moment_scale = 3
pitch_damp_moment_scale = 3
bank_damp_moment_scale = 3

As I understand 0,6.045,45.0 is the x, z and y position on the flightdeck.


The DP file is set as a carrier.
[MISC_DATA]
unit_family=7
category=13
allegiance=1
min_speed=0
cruise_speed=30
max_speed=55
entered_service=12/1/41

Any help would be appreciated.
Cheers

Flightdecks make my head hurt. It may help to attach the ship it self.
 
Hi Stuart,

I think you're positioned just short of the platform, & so dropping through

...
; AI (and LSO) use to steer towards the flight deck
width=10.25
length=131.25
takeoff_start=0,6.045,45.0 ------- 45mtrs from z axis zero
takeoff_stop=0,6.045,64.7
landing_start=0,500,-5000
landing_touch_down=0,6.045,45.0
landing_stop=0,6.045,62.0

...

vertex.0=-1.267,6.045,64.701
vertex.1=1.267,6.045,64.701
vertex.2=4.335,6.045,46.46 ------- platform finishes 46.46mtrs from z axis zero
vertex.3=-4.335,6.045,46.46 ------- platform finishes 46.46mtrs from z axis zero


I think you a/c is dropping 1.54mtrs short when positioned for take-off.

Hope this helps
 
Exploding Aircraft

Thanks Guys
UncleTgt, I changed the takeoff start spot and made the flightdeck a little larger. This made the aircraft 'sit' on the flight deck. Unfortunately it then explodes!!!
Allen, attaching the flightdeck to the hull did not seem to make a difference.
All the aircraft I tried go boom, nice effects though.
Interesting?
Cheers
Stuart
PS Although it is difficult to notice in a picture, a couple of panels on the port side, admidship, 'flicker'. Port side only, you can just make out a lighter coloured panel below the aft 4 inch and 6 inch guns. All the nodes seem OK. The fall from the foc'sle to the main deck was done by extrusion and then lining up the nodes.
 
I ment attach the ship to a post so we could try messing with it. I messed with Flightdecks before but don't have any of it memorized to well.

One thing of note is that the starting point can be a foot or more off any direction in CFS2 so make your platform over sized.
 
GMax Files

Hi Allen
Thanks for your intererest.
I have attached two files, each has the GMax files included. The only difference is the position of the flightdeck. Both have the exploding aircraft program.
I have been making these models for polar lion, who is keen on WWI ships, and the Arethusa Class were the first to launch aircraft, French Moraine monoplanes.
Again, thanks, and good luck.
UncleTgt, I still haven't got my head around the DP file editor for the Starling.

It make no since as it should work but don't. When CFS2 make no since do crazy :censored: and hope it works.

What I did was plug a "dummy" flight deck on the back of the ship that has no width almost. This stopped the insta boom.

Give this a try.

Genius

Hi Allen
That worked!!!
You are a genius:salute::salute::salute:

I will send this over to Polar Lion, as he is keen on WWI things.
At the moment I am learning GMax by doing ships.
If you would like me to do a ship for you I would be very happy to give it a go.
Again, thanks for your help.
Cheers
Stuart
 
If you can do the HMS Furious as used in the Zep Tondern raid. I did the Tondern Zep base and Polar_Lion aka Blood_Hawk23 was working on 50lb bombs for the Sopwith Camel before he dropped off the face of the earth (or at lest SOH).
