737 HUD

1st Official Post

    Hello, everyone. I would like to ask if anyone knows how to drive the code on the 787HUD. I want to port the HUD system to the 737. I already have HUD modeling and screen, but after I copy all the HUD-related code to the 737 system and modify it, the animation can be played normally, but the display shows a weak green color and there is no content. It does not seem to rotate and put it away with other objects. Is there any expert in this field? I hope you can help me.

    Adjusting the brightness can only change the brightness of the hud content, and the color of the whole glass of my hud has darkened, which looks strange. I noticed that the 787 in the game seems to render a virtual screen directly in front of the hud to present the content, which I don't know very well how to achieve.

    I noticed in the code that you sent that you are using <[string8][TextureName][hud_color]> I think this should be <[string8][TextureName][hud_light]> as its the hud_light ttx file that carries out the luminance

    As it happens I am also trying, with no luck I might add, to install a HUD/Moving Map on a display in the Navigators station. I have dont this before on the Apache but it still refuses to work.

    I have tried the name hud_light, but the object name in graphcis_hud does not appear.

    I studied your F104G aircraft yesterday (although it can't run on FS4), but I noticed that it also has HUD and uses the same graphics_hud object name as F18 in the game. GeometryList name is also HUDPro. What is the definition of this object? I can't show this object in the game anyway.

    I think this object is a virtual screen, and the content of HUD is mapped, but I don't know its principle.

    Hi

    The code is using an object called 'DisplayHUDLeft' which you have already found out and which I'm also assuming the HUD coding is projected on. This object may well be included in the 787 model base but I'm unsure if the 737 has such an object. Unless you have made this object it may need to be 'obtained' from the 787 and then repositioned to match the 737. The HUD itself seems to be internal to the game and we simply copy and paste what bits we need in the hope it may work.

    With the F104 I did make a separate object as a HUD glass where the HUD was projected on to. As I have always built my own models I have never found the need to 'obtain' parts from a prebuilt TMB file. If that is at all possible which I doubt. With My C130 I am mapping the Navigator's 'HUD' texture onto the Moving map screen so this is yet again another method of inserting a HUD. I decided to do this to avoid building all the gauges the navigator would need to fly from his station alone (blind flying for the very brave). Having seen the inclusion of your HUD I may well model one for the C130 although I don't think many H models ever had one fitted. Will consult with the team on this one.

    Thank you very much for taking the time to reply to me. I did make an object called DisplayHUDLeft in the modeling software, which is the green part in the picture. I tried to take out part of the 787's tmb, but after testing, it didn't work. Can you tell me in detail how to make HUD display content, such as heading, speed, altitude, etc. Thank you very much.

    From what I have been able to work out, which may only be a small part of it, the information comes from <[display_b787_hud][PilotHUD][]

    We do have to ensure that all the dynamics call that it needs are also inside the dynamics section. As with pretty much everything in the tmd the sections are all interlinked. Some information displayed will also be linked to the FMC and so the list goes on. Like I said before, I copy and paste and hope it it all works. If not, spend days searching for the answer and if all else fails, bow down to Grand Master Jan Kenobi and he will answer all, hopefully. HUDS and FMC's are complicated bits of coding and quite a lot is not visible to us mere mortals. This is also dependant on what sort of HUD as the F18/15 are vastly different to the Boeing/Airbus stuff.

    Have you tried to use one of the glass displays that are showing in place of the DisplayHUDLeft. Depending on how the glass is mapped in the model it may work it may not, worth a try. Are there any extra files, ie tmb etc that are needed. If so you can always pm them to me and I'll have a go at my end too.

    Yes, I did use glass instead of the display screen during the test befor. As a result, the content of HUD can be displayed, but the whole thing becomes very dark, as shown in the figure below. In addition, if you are free, I will upload my blender engineering file and HUD file to the cloud and send it to you, but not now (I'm eating):)

    Thank you very much for larrylynx's guidance, which inspired me to complete the mapping of HUD content on the virtual screen. However, now HUD is not perfect. The content displayed is too large and even exceeds the range of the monitor. I have tried many methods, such as modifying the scaling parameters in tmd. This method only works for 787, but there is no change in 737. Now the only thing that can work is to enlarge and reduce the model and move the position of the model, which can make the display content reasonable. But if this is done, it will make the proportional imbalance of HUD look strange. Does anyone have any other way?

    Oragz and myself have been gradually coming to terms with the HUD system within the sim and I'm glad to see his 737 Hud based on the 787 is working. I too have a working HUD based on the F18 but have run into 2 problems I cannot fix. The HUD always stays visible and there is a streaking in the image, if I substitute the basic F15 Hud there is no streaking. I am assuming the brightness value dictates if the HUD is visible but I may be wrong and that it is an transparent object with the hud_light projected onto it using the brightness value.

    Any guidance Master would assist my fast disappearing hair line.

    Hi larrylynx, I will sort out the files later and upload them to the cloud disk. You can download my latest file. At present, it seems that my code can click HUD➡️HUD to appear, click the second time, HUD is closed➡️ display content is closed.
