• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Textured PAPIs with 2004 gamepack problem

Hi all

After enough of the BGL_LIGHT limitations, I've made some new APAPIs with textured light planes and multiple LODs. These work fine when compiled. I've tweaked the code to include 2 separation planes - one for each light fixture. However, only the 2nd sep plane works, no matter which way around they are in the code. So originally the left PAPI was 1st in the code, and would only show the white - never switches to the red. Right PAPI working fine. Change it in the code so the right PAPI is 1st in the code, it stops working and the left starts. I'm baffled at this one. Removing one of the sep planes so only 1 light is enabled causes it to still show white and never change to red. The code within both sep planes is identical except for the calling of the textured planes and jumps.

The code is quite lengthy to post, but to sum it up is goes like this:

DRAW_TRIs
DRAW_TRI_END

SEP_PLANE lamp1a, x, z, y, 32768
white light code
BGL_JUMP_32 lamp1b
lamp1a label BGLCODE
red light code
lamp1b label BGLCODE

SEP_PLANE lamp2a, x, z, y, 32768
white light code
BGL_JUMP_32 lamp2b
lamp2a label BGLCODE
red light code
lamp2b label BGLCODE

BGL_RETURN

So basically with the above lamp2 works and lamp1 is always white. Switch them around and lamp1 works and lamp2 doesn't. Any help would be greatly appreciated.
 
Hi,

The code structure you posted here looks fine. So I would double check your actual code to see if you did not misspell one label or so.
 
Hi Arno

Checked the code lots of times. With lamp2 working I remove lamp1 and lamp2 stops working. It seems to be that the 1st one of the 2 doesn't matter which it is doesn't work.
 
Can you show the part of your actual code with the SEPARATION_PLANE commands?

Hi,

How did you produce this overly complex code? I don't actually see the part that actually draws any light.

Since there are so many checks and jumps, it could very well be that one jump is skipping part of your logic. But that is very hard to debug.

Do you actually need the LOD checks and all those on the lights? My feeling is that it should be possible to make this much simpler.
 
OK after a few hours of messing I've figured out the problem. It appears that the X and Y values needed to have their signs changed around, so the + value was made -, and vice-versa. Interestingly the other lamp was correct. Glad it works, can finally move away from bgl lighting :). Thanks Arno - if you have a way of making the code simpler please let me know.

Glad to hear you got it working.

About the code, I assume you used GMax to model? I have not seen such complex code for lights before made by GMax. So not sure how to improve it.
 
Hi Arno

Yes Gmax and FS2004 gamepack - this is the code it spewed out. Technically they are not lights they are planes textured with bright light looking circles. That's ok they work which is the main thing. Just trying to get wind direction factored in and they should be finished.

EDIT: Turns out I can't get the wind working - does it work in FSX? I've added this on the line before the sep plane:

IFIN1 windrange, 0C74h, 1999h, 9999h

and windrange label word at the end.

According to MDLTweakerII the c74 variable takes 0-65535 for headings 0-360. After trying IFIN1 windrange, 0C74h, 36, 216 for my heading range I divided 65536 by 360 to get 182.04, which I multiplied 36 and 216 with to get 6553 and 39321 respectively. The hex values of these are the ones above. None of the 3 sets of values work. Which one is the correct one for only showing the sep plane at a certain wind direction (between 36 and 216 degrees)?
