# Help with my aircraft carrier flight deck

## Recommended Posts

Aircrafts can't get enough speed to takeoff because they either collide or slow down every time they pass through a line (on the 3d model), and sometimes, the aircraft starts jumping around

The ship is static, and has a flight deck which is 260m long.

I'm not sure, but I think the problem is the geometry. Could you guys help me to understand what is the problem and how can I fix it?

Which plane do you try? On the Nimitz we have good results with aircraft w/o physx simulation, e.g. the F/A-18E/F from Spartan&Saul. But then, the catapult is scripted so the plane does not take off 'normally'.

somewhere between the vehicle suspension and geometry features incompatibility testing even suspension of a land vehicle.

I can use available script for this project?

Rework:

Sure, you can use any and all of the Nimitz scripts for your project, though probably you want to modify them for use of your memory points and such. Feel free to get in touch via PM if you run into troubles.

What also comes to mind for causing the problem is the separation of the different LODs. On the Nimitz the road lod is layered above the res lod above the geo lod. Maybe that order would help too.

The most likely explanation is that the geometry connection between the two hull sections may not be as exact as you thought.

I believe you need to use the old non-physx collision geometries.

Somehow there is something in the new a3 buildings and physx that just breaks proper takeoff with jets (it bumps in the air as soon as you move from one block to the other).

I had the same exact problem with my harrier and the Atlas LHD, while the problem doesn't happen with Chortles' LHD or the "static" model in Utes.

So my advice is, go open the LHD from the APL-SA source files, compare it to yours and change accordingly.

Also the airplane needs simulation = "airplane", aside from (imho) pointless complications while rolling on the ground (my harrier would just get damaged or explode while turning slowly on the taxiway) i found no benefit whatsoever between the old and new simulation.

Hope it helps, good luck.

so I have some result, I will send.

I will keep this topic updated to partially complete the ship.

YES :cool:

Sorry, I was out for a while, re-working model and other personal affairs.

And it seems that something has changed.

This config and script to join parts, but does not work correctly, the same as static form:

Obs.: This happens only in the 3D editor

VÃ­deo:

1- For F5 seems that this track as land with stones

2 - For AV8B he runs like in Formula 1 track

Hey there, i think i know your problem, what simulation type are you using for the F-5?

##### Share on other sites

Chairborne get's the cookie - yes AirplaneX is the reason. Switch simulation type to older Airplane version, it's more forgiving if you plan some carrier stuff...

B)

We had our fair share of curses and wasted time while working on CUP's LHD and the F35/Harrier.

Aircraft that will be used is in development (A-4 Skyhawk), F-5 was only to show why he does not make the taxi or take off just as AV8B.

Currently have the same problem :(

Day 14/06/2016 made some changes, now now works as AV8B but is prancing.

That is probably related to mass distribution on the plane.

After much suffering, I got a good result.

1) Lod LandContact had 3 points, which caused imbalance of the model on the ground.

2) added 3 more points on the back, for correction of balance of the model soil.

3) Operating at Nimitz, being prepared for aircraft carrier SÃ£o Paulo

Thank you all.  :)

Reported problems at the beginning of this post, have been fixed.

Obs.: We still have some corrections to be made.

Update:

- Model of the aircraft carrier corrected.

- Re-worked configs.

- A-4 Skyhawk to functional aircraft carrier SÃ£o Paulo.

- A-4 Skyhawk losing life (related to ship?).

- A-4 Skyhawk not get speed above 20 (related to ship?).

Good job. You need simulation = "airplane" for the skyhawk to work correctly.

Try using the harrier from CUP and it *should* work fine by comparison.
