Author	Topic: Open Plane Genius Needed!
ArgonV Pilot	posted 07-16- 03:25 AM Ok, I cant for the love of God figure out why my Mistel jumps in the air at the start of take off!!!! Would any Open Plane Genius PLEASE help me with this?!?!? It doesnt make sense! Why would a Ju-88 straped on the bottom of a Bf-109 make the whole thing Jump? Maybe its the obPoints or something, but I dont have any clue about that stuff. If I have the Ju-88 as the parent and the Bf-109 as the child it takes off just dandy! But everything else doesnt work right. But if the Ju-88 is the child and the Bf-109 is the parent it jumps in the air at the start of takeoff but eveything else works just fine. If this problem could be solved thats basicly it for the Mistel. There are only 3 problems left to solve and this jumping one is the most important one! So I beg someone, help me! IP: Logged
CrossbowArcher Pilot	posted 07-16- 03:33 AM Jumping? Maybe because of spring DOFs in the ju88's gear IP: Logged
Sv Pilot	posted 07-16- 02:11 PM Maybe the parent object (fuselage) is no longer centered at the origin, or now the model is larger so it starts in SDOE below the ground a bit - I think this can cause the plane to shoot in the air, but I am not sure. You can fix the obWheels points to line up where the ground should be, or maybe move the fuselage upward in OPS. I'm not sure that moving the parent model does anything in OPS though... ------------------ -Sv =FC= WWI in SDOE! IP: Logged
ArgonV Pilot	posted 07-16- 02:31 PM If its the springs, how to I change them? I know nothing about springs and damps. Sv, the model starting below the ground does not cause it to jump. Ive experimented with this as well. And as for moving the fues up in OPS... no go there either. How do align the obPoints with the wheels? How do I figure out the cordinates? IP: Logged
Pete Hawk Pilot	posted 07-16- 03:00 PM Argon, Been there, done that. If you see in the other thread I already moved the 109's wheel ob Pts down to where the Ju88's were, and still, same problem. That was a no go. This is very puzzling. IP: Logged
ArgonV Pilot	posted 07-16- 05:32 PM 3/4 OF THE PROBLEM NOW SOLVED!!!!!!!!!!! The plane doesnt jump any more! The gear works in sync (even when you start in the air) and the tail wheel of the Ju-88 now steers the plane. You can now land this thing without destroying your gear on the slightest little bump or bounce. Only one problem and I think it can be solved by someone with AC3D (I dont have mine regestered) The plane starts out too low to the ground i.e. The gear are below the ground when it starts. BUT if you raise the gear so they're above the ground and lower them agian the gear works fine! So does SOMEONE, ANYONE know how to make the plane start out higher above the ground?????

Pete Hawk Pilot	posted 07-16- 06:43 PM Argon, could you send me your new SM so I can check it out? thanks Using AC3D, I'm gonna see what I can do about that gear problem. Only problem is though it'll raise the entire model higher and could really adversely effect the FM. [This message has been edited by Pete Hawk (edited 07-16-2000).] IP: Logged

Only problem is though it'll raise the entire model higher and could really adversely effect the FM. Ok, back. Yikes, that was a mistake. All the DOF's got thrown out of whack! I went to start the engine (after having half crashed while trying to get it parked on the ground at mission start-up, didn't flip but it was still way unflyable) anyhow, trying to start the thing up and all the props DOFs were way off. I made sure the gear were even with the ground in AC3D, and still, it was crazy at mission start up, pieces flying etc. So much for that idea. IP: Logged

ArgonV Pilot	posted 07-16- 08:40 PM Pete, check your mail. Here is the new sm. See what you can do with it. IP: Logged
ArgonV Pilot	posted 07-16- 09:50 PM Does anyone know how to make the plane start higher above the ground???? This is the last problem IP: Logged
ReaperMan Pilot	posted 07-16- 11:18 PM ok, how do you get this sucker to detach? I have been messing with it some... no need to change anything in AC3D. I fixed the bouncing and the steering problem too. Just got back from a testing session, everything looks pretty good. I'm going to make a few more changes, then I'll send along the SM. Regards, ------------------ -=TheReaper=- IP: Logged
ReaperMan Pilot	posted 07-16- 11:20 PM P.S. It does not start with the wheels below ground The prop is showing the bent prop graphic tho, so I'll go ahead and fix that now. ------------------ -=TheReaper=- IP: Logged
ReaperMan Pilot	posted 07-16- 11:28 PM P.P.S. OPS doesn't like this plane... too many crashes ------------------ -=TheReaper=- IP: Logged
ArgonV Pilot	posted 07-16- 11:31 PM ReaperMan, you press the 'A' key. Make sure you have this in your keyboard.inp folder... cmdBomb = A Also, you must be going at least 220 mph for it to detach. HOW DID YOU GET IT TO NOT BOUNCE STARTING ON TAKEOFF?!?!?!?! I LOVE YOU IF YOU FIXED THIS! THANKS SOOOOO MUCH Its showing the bent prop? Thats wierd... cause mine doesnt. P.S. I must know how you got it to start on takeoff with out bouncing off the ground. IP: Logged
ArgonV Pilot	posted 07-16- 11:32 PM OPS doesnt crash it on mine... another odd thing... IP: Logged
Pete Hawk Pilot	posted 07-17- 12:27 AM Argon, that SM you sent me... when starting a mission on the ground the wheels are UP and my JU-88 props are instantly bent. The wheels can be lowered but then it's standing on it's nose. I went into OPS (my won't crash either) and adjusted the gear so extends backwards and am able to now get the plane sitting right (this is AFTER the props are already bent out of shape) so it's still kinda useless. Reaperman, if you fix it PLEASE send me the SM file too. I'm itching to see this interesting plane start on the ground right. Thanks. IP: Logged
Pete Hawk Pilot	posted 07-17- 12:30 AM Argon, you mention 220 to detach, mine detaches sitting still! Speed won't effect mine at all. All I do is hit the "A" key and away it goes. (thats just ARMING bombs in SDOE). I also have your command in my keyboard INP file but it doesn't seem to matter. "A" does it all for me. Wacky isn't it. IP: Logged
ArgonV Pilot	posted 07-17- 12:41 AM Ahhh!!! This plane does wacky things! What monster have I created? LoL IP: Logged
ReaperMan Pilot	posted 07-17- 01:05 AM It all has to do with obWheels. The OP engine is dropping the a/c too hard on the ground (or too far). I put the wheelpoints of the Ju88 in obWheels. Right now I have this to set everything once the 88 drops: (onChildDetach 'Ju88G7b (obWheels -3.96789,6.97498,-5.4814 3.96789,6.97498,-5.4814 -0.221455,-11.6181,-1.31704 vehSteer 'tailGear vehTire 'leftWheel 'rightWheel 'tailWheel phyLBS 5000 aircLeftWing 'leftWing 'WngTipL aircRightWing 'rightWing 'WngTipR aircHStab 'horzStabL 'horzStabR aircVStab 'vertStab)) One more test and I'm going to bed I have to work tomorrow morning... ------------------ -=TheReaper=- IP: Logged
FarmerJoe Pilot	posted 07-17- 01:24 AM Okay I had a problem with a plane bouncing violently into the air once and here is what it was: The prop DOF was way off and the propellor swung around at struck the ground at threw the plane way up in the air! I corrected the propellor DOF and everything went smoothly unforunately what I was working on never worked correctly! It sound as if this plane is doing mysterious things hehe I need to get a look at that .sm file I cannot test it but can look over some things and do some modelling if some is needed just email me at: jameso@cdsnet.com ------------------ Subaltern FarmerJoe Axis West Three Amigo IP: Logged
ArgonV Pilot	posted 07-17- 01:29 AM ReaperMan, so when you start a Taking Off mission the Mistel starts on the ground, together and does not 'bounce' or 'jump' into the air? Will you send me the sm after your test? IP: Logged
ReaperMan Pilot	posted 07-17- 02:29 AM Man, I seriously need to get some sleep. I finally got the Ju88 to detach, but only in v1.5. Didn't seem to work in build 65. I will send a more polished version tomorrow, might be late b/c I have to work from 9AM to 11PM. The key to getting rid of the jumping is to change the obWheels on Mistel1. ------------------ -=TheReaper=- IP: Logged
ArgonV Pilot	posted 07-17- 04:38 AM Hehe ok ok, I'll not pester you anymore. I did change the obWheels on Mistel1 and it halfway worked! Only problem is the left gear starts out below the ground but the right gear is above the ground. I also added brakes and the tail steer to the Ju88G7bs wheels. Thanks for figuring this all out ReaperMan This is MUCH appriciated. When these problems are all sorted, I'll do a little touching up and release this sucker to the public. IP: Logged
ArgonV Pilot	posted 07-19- 12:48 AM ReaperMan, how goes the Mistels wheels? Are they fixed? I havent gotten all my wheels to work yet.. IP: Logged
ReaperMan Pilot	posted 07-19- 11:57 AM No clue as to why they aren't working. I've got one with wheels that work, maybe you'll want to import the new LOD into that one?... Strange indeed and I still can't figure out why my props are APPEARING bent. I'm pretty sure it's only an appearance thing, because I am still able to take off (with full flaps), even if I turn the 109's engine off. Anyway, I'll send it before I leave for work. ------------------ -=TheReaper=- IP: Logged
ArgonV Pilot	posted 07-19- 07:27 PM Ok I figured out the problem. I changed the obWheels numbers one set at a time. It was the tail gear obWheel cords. I fixed that problem so it now takes off and the props dont appear bent. Download the new Mistel ReaperMan and tell me if they still appear bent for you. Delete your cache files if they do still appear bent. Thats all I can figure. IP: Logged
Pete Hawk Pilot	posted 07-19- 07:58 PM Argon, Can you send it to me too? IP: Logged
ArgonV Pilot	posted 07-19- 09:33 PM Pete, check the general or download section. Its ben posted for download. IP: Logged
