Unsolved Bug Report: Jdam/Loft - physics bug
-
Okay
We have been unable to reproduce internally what we see in the video
Could you provide the TE you are testing and the exact procedure
-
Sure thing,
Pls find TE here
Exact Procedure I followed:
1.) 2d fast forward as needed. Load in 3d with jet en-route stp 2.
2.) Arm the jet + power on the bombs + Rdr Alt on.
3.) Auto pilot + 3d fast forward to Stp 2. Allow bombs to align “RDY”
4.) Setup for CCRP loft attack on from STp2 to Stp3. Approx 500kts IAS and 80ft
5.) Cleanup HUD with Scales switch (“H” key) to see “LOW” warning clearer.
6.) On ingress to target. Ensure “LOW” shows on the HUD (between 110ft - sea level. “LOW” disappears above approx 120ft, so you need to be lower than that).7.) At 20deg on DLZ and with “LOW” warning. Press and hold pickle + pull to 20deg nose up on HUD
8.) expect bomb to come off early followed by uncontrolledly state!

Confirm you are pressing and holding pickle before the pull?
… watching the SMS page in your vid, it only switches from “RDY” to “REL” after you start pulling. I think what’s happening is you are pulling before pressing and holding. so you’re already out of the “LOW” parameters when you press (and hold) pickle.

No, I didn’t hold pickle at that time because I was sure I didn’t want to release while flying that way.
Fine, now it happens. The bomb releases immediately while flying 50 ft, my take is that it considers you’re not trying to loft and therefore drops. Why does it do it to your aircraft?
If it happens to other clients on the server away from you, at the same time, there is a first problem to solve.
For you in particular, is it the same bug, or is there a different problem? The bomb might be releasing in a legit way but not do damages since not exploding. Unless it hits your aircraft back after release within these abnormal parameters? Not shown in 3D if this is what happens, there is no visible bomb in 3D nor in Tacview. But you can hear the release from the cockpit and hear a boom from outside.
11 minutes.
In devs’ hands.

First i am unable to repro your bug , the GBU does not drop early , it drops when the FPM reaches the marker as it should
second, i dont have the “LOW” in the hud, how do you trigger it ?

I exactly followed that procedure plus the correction we discussed above. It triggered the LOW and everything else.

unable to trigger the LOW and unable to get the bug
the only thing i dont understand in he procedure is :
“4.) Setup for CCRP loft attack on from STp2 to Stp3. Approx 500kts IAS and 80ft”
what does that mean ?

Im not doing anything wrong , I’m just flying a different version that does not exhibit the issue anymore
Now we are working on the PUac and Low mechanisms for IAM and see what we have right or wrong
Leech you can take the lead here as you want
-
@Mav-jp
You trigger the “low” warning by increasing the fuse delay. If the computer calculates that the bomb will impact before fuzing, it displays “low” on the HUD.
So either fly lower, or increase the fuze delay to get that warning -

The problems of troubleshooting, “Not my fault” . If you want to trigger as we did, accept the kind help. If you don’t… I never use JDAM so I will use my time on something else.

For sure you are not a beta tester but we don’t master all single bit of code and procedures on our side.
We are all knowlegeable in specific aspect but we speak code and not always procedures…
That is supposed to be the beta tester’s job to translate this for us… -

Yeah sure I am seeking of reproducing the bug hence I tried first on my dev version. And then I realized the code has been changed in that area
So it seems this specific issue is solved however it did open question marks about LOW and PUAC for JDAM
Could someone confirm that triggering that bug in MP makes all clients blackout in the same time ?

I just triggered it from the client to the (rendering) server that was flying a DPRK F16 meanwhile.

You mean the server blacked out ?

Great
We are about to fix a very old bug I believe
-
Good news
This repro case has revealed two very serious bugs
(The release bug was fixed already) - in particular one about arming delays and the other critical about NaN spreading all over the codeWe will work on them
-
Nice ! Party time ! Thanks to the BMS team
