I attached a P-51d onto a B-17 and added obRopePts. Well it worked! I towed a P-51d down the runway a tad bit with a B-17! It blew up soon afterwards... but Ill fix that! Ill post a sceen shot laters. Im going to go play with this more!

Great work ArgonV, this will go really well with the C-47. Now if we could only get the parachutes to work on cargo and other things.

UPDATE: Well got the P-51d to stop blowing up. Now Im experimenting with the placements of the rope points. I took off in a B-17 towing the P-51 but that thing swayed all over the place! Im trying to reduce that now......

Wow

Would something like this make the possibility of having a plane with a rope, and a hook, snag soemthing and lift it as it flew by?

Aron you just keep experimenting, and we will keep being amazed.

Unless you're flying multiplayer you only have one pilot for your tests. Wouldn't it make sense to let the AI takeoff the B-17 and you fly the P-51 to avoid the swaying? Or are you in the P-51 and getting uncontrollable swaying? I don't think even a "real" glider, unmanned, could be pulled without a lot of swaying.

Great job Argon! Man this is so cool, I really hope you get it working. Since you did the Mistel my faith in you is very high

Ok, Ive limited the swaying on takeoff. Now the problem is to limit the swaying in air. I really need a glider instead of this heavy P-51..... If someone could knock me up a glider with the correct lifting airfoils I THINK I may have this thing cracked.

If not I have one more trick up my sleve to keep this thing from flying around all over the place in the air...

P.S. I cant control the P-51 once its ben detached. That was the problem I had before with the ability to control the Mistel once it released from the Bf-109 These things work hand in hand!

Argon, if you could, zip it on over to me and I'll spend some free time on it also. This is too cool.

Sure thing!

UPDATE: Ok I limited the swaying in the air and got the P51D glider to fly up at the B-17 towplanes altitude. I just edited the airInc of the P51ds wings. Now its fine until you pass 155-160 mph. Then the glider starts swaying around lots. She still doesnt want to behave if I start out in mid air. I know its something to do with the ropePts but I have very little clue as to what the values should be....

MH?

Argon,

Starting in mid-air works fine for me! I just set the starting airspeed to 148 knots and the altitude to 1500 and it works fine. I can tow the P-51 around all day, but is there a way to detach it yet, and/or control the P-51?

Anyways, great job! This is a very cool new idea that after some more tweaking will really open up this sim to many more cool things. I'm very amazed and glad that this is working

Maybe I'm using a different airfoil or something, but I can fly fine up to 230 knots or so (before no more speed possible with B-17f) and the P-51 behaves fine, very stable.

Now my thoughts are these though. Unless we can't detach the towed plane, or take control of it I'm not sure just how useful this new breakthrough will be. It does look really neat though to do a turn and see the towed plane keeping up.

it might not be bad if there is a person in the other plane to fly it.. and it would be nice to have the rope drop on a key press.

Hmm, I turned on invincibility and I can go barreling down the runway and the P-51 gets airborne and flys nicely behind the B-17, but the B-17 cannot fly! It's just a fast ground vehicle. Strange.

Pete, theres away to detach the glider from the B-17f. I just havent gotten that far yet. Now I havent tried this with invincibility on so I have no clue as to what might happen. Now when you fly the B-17... is the P-51 actually gliding behind the B-17 or is it stuck there like a part?

At this point in time I cant figure out how to control a vehicle after its ben detached from its parent. I can put a pilot seat in the P-51 and you can sit in there while the AI tows you around... but you cant control it.

In the mail you said the P-51 blows up on you if you try to takeoff from the ground...? Im curious are you using a MH beta patch? I can take off fine but starting in mid air is a problem.. the P-51 likes to do stunts behind me. I also have a problem going over 160 mph. The p-51 likes to do loops....

P.S. What kind of SDOE installation do you have? PP6? This also could be a problem. We need to get on the same page here as to what everyone has installed on their SDOE.

Disregard! Got it working, I was using an older version of SDOE. It's really nice taking off from the ground now. The P-51 is definitely acting like a glider being towed, I love it!

Oh, about the ropepts, how in the heck did you place those? I see your coordinates for them in the properties window but have no idea how to place them on both the tow'er and the tow'ee. Can you give some advice on how you did that?

Thanks

Man this thing is fun. It's just a riot to fly around and realize you are towing another airplane! I'm doing some brainstorming to come up with some neat things we can try with this. One thing that came to mind is this, have say 2 or 3 planes attached to your main plane (say a diamond formation?) and do an airshow and even have all the planes smoke. That would look so cool since they wouldn't be perfectly still. They'd bob around as you manuever and it'd look pretty awesome I think. Another thing, try and have a chute drop (say as a pallet or a small box of munitions to resupply the ground troops) and as it floats down other small parachutes detach from it and you see a nice grouping of chutes float on down.

I think the ultimate though would be this: have a glider on the ground with it's ropept's able to be grabbed by a plane overflying it and picking it up (the end of the tow rope) and suddenly WHAM! off you go! So, time will tell what can be done with this.

Pete... whew!!!!! Im SOOOOO glad its working for you. I should of told you that you needed the latest P51.... Sorry! Ive also limited the swaying more! You want to know what was causing it? THe fuel on the P-51! That adds weight and since gliders dont need fuel, I took the fuel tanks out and added 300 lbs. Now it glides just right behind the B-17!

To place the ropepts.... lol I have no clue! The ropepts you see are the parachute ropepts that I copied/pasted onto the B-17 and P-51. I do know this (I think) The first 3 numbers are X,Y,Z cords (The could be inversed I think... but for now Ill say they are X,Y,Z) and the two numbers after that I THINK are the rope number so you can say what ropepts will attach to what ropepts. So it should look something like this: 12,16,18 1,0 The first three are the cords of the ropept and the last two numbers are I THINK rope # 1.

As for your implementations... Ive ben thinking about these ALOT! But one small step at a time.

P.S. Now when you start in mid-air, does the P-51 fly ahead of you? Mine does...

Out of sheer curiosity, what is shown in the plane selection menu if you start a multiplayer session with the combination of these two planes?

Great work guys, I am really looking forward to this. I wonder if the rope properties could be enabled/disabled with dof commands?

I wonder if we combine Pete's idea using a dof to pull objects (ships, Zep, etc.) and ArgonV's rope trick, if we could make a train that was pulled across the ground?

After following Michaels insite about the detach and ropept's, I was able to copy and paste a parachute onto a bomb and make it open on release, so droping crates/supplies should work (as well as paratroopers). I still have to work on the air properties because it still falls like a rock/bomb but sure looks cool.

Of course you do realize you may have just solved the carrier arresting hook and wires problem, don't you? Think of towing a "rope sling" behind you, and placing "hooks" on the deck of the carrier...

Looking forward to getting a chance to play with this some...

Argon,
Way to go! If you want to try something that acts more like a glider than the P51, you have it on your computer already. Try the PBY!

Hmmm........

Raider glad to hear you got that working! I was about to try it but now that you have it working, I'll rest the responsibility on you to make parachutes for supply crates and paratroopers.

If rope properties were attached to an object, and that object had the DOF to disable and hide it, the ropePts SHOULD get disabled just like bodyPts do. (Ive tried this with arrestor hooks for the Corsairs, Zeros and F4F4s)

Now as for the carrier arrestor wires.... I dont think the ropes are "solid" which means you can pass right thru them. If the ropes were solid, then you can attach a rope across a carrier deck and see if the hook catches it.

Snickers, its true the PBY flies like a glider, but its WAY too big and WAY too heavy to use for testing. Besides, the test P-51 Im using now does fine.

I'll not make any gliders and such. I'll leave that to the model guros since I have AC3d BUT its not regestered. I'll just do the OPS stuff and figure out how to implement these ideas.

Cheers!

Hehe the ROPES don't have to be solid! In the tow plane example, the towed plane is solid, right? Imagine you were towing a plane, and you landed the tow plane just past another plane. What would happen when the (solid) towed plane got towed to the (solid) parked plane? Boom, right?

Now, imagine, instead of towing a plane, you use your obRopePts to "drag" a (solid) "bar" about 15 feet wide. You can set the switchin on the bar to a low number, and it will SEEM to be invisible, but as long as you give it some weight and a phyCylInertia, it will be a solid object.

Now make a couple of (solid) "hooks" sticking up from the carrier deck (the Ark Royal already has some things sticking up that your plane can hit). Give them weight, inertia, and low switchin values to appear invisible. If you put DOFs and spring properties on these "hooks," they could absorb a certain amount of "shock" from impact. Now imagine you land just past the hooks, dragging your lateral "bar" object by the rope points. What happens when the lateral bar "hits" the hooks?

Good idea! Only problem is, when the P-51 detaches from the B-17 so the ropePts can work, it looses its bodyPts and thus can pass thru objects. Ive tried that a while back to see. I dont how this would affect the hooks bodyPts. Whenever things get detached from their parents, they loose the bodyPts they have and get either new ones.
Example: (onChildDetach 'tailFuselage (obBodyPts (verts -1.12943,-23.2091,-7.78434 1.12943,-23.2091,-7.78434 2.95942,-23.2091,-2.12306 -2.95942,-23.2091,-2.12306 )))

Or loose their bodyPts completely.

Plus you would have to make the ropes and hooks inactive until you drop you hook. (Just use the breaking DOF method for this) Otherwise your hook-pully system would hit other things aswell!

The PBY uses a NACA0021 airfoil, and has 1400 sq' of wing area.... You should be able to make these changes in OPS. Of course, it wouldn't fly like a P51 anymore... (sorry raider )

Ok, got the P51 glider to detach from the B17 towplane on a button press! Only problem is AI cant do it... and you cant control the glider, but oh well. Now I can watch the P51 glide down till it smacks the ground!
