    3° Changing it to (atan2(x,y)+180°) as suggested by @oleg gives incorrect results

    I'm not suggesting the formula you indicated
    magneticHeading = (math.atan2(fx, fy) + math.pi) * (180 / math.pi);

    @oleg, that's what I wrote, except that I reasonned in degrees and not in radians (and assuming my atan2 includes the conversion to degrees)

    @hgy29
    ps//
    My formula shows the correct results even without the calibration of the magnetic sensors, the compasses available in the store without the calibration show the wrong result

    I do get what you say, but lets face it: if apps on the store gives incorrect results for you, then it is probably your phone that has a non commonly placed sensor... I don't want to offend, but do you have another phone to check ?

    I checked on 5 devices

    The apps in the store give the right result, but before using the apps you need to rotate the phone to calibrate the sensor

    I have a tablet from google, I doubt that the sensor is non-standard

    I also checked on third-party devices (samsung,lg)- everything works the same

    On the phone from lenovo - does not work because there are no magnetic sensors there

    I checked the Gideros compass example code against the 'built-in' Samsung app on my phone - same results. BUT, if I put the phone vertical the Samsung app stays accurate but the Gideros app flips 180 degrees.

    (this has apparently been fixed in a newer version of Gideros, will be able to check tomorrow I think when @hgy29 gives me the apk).

    in the example of gyderos there are 2 errors

    Replace the example code with this one and check on the player with the screen rotate automatically

    @oleg I'll do that if the new apk given by @hgy29 doesn't work - downloading it this morning.

    Also if it is not difficult for you, check to compare these 3 formulas on your device
    fx=event.magneticX
    	fy=event.magneticY
    	fz=event.magneticZ
     
    	 magneticHeading = (math.atan2(fx, fy) + math.pi) * (180 / math.pi);
    	 magneticHeading2 = (math.atan2(fx, fy)) * (180 / math.pi);
    magneticHeading3 = (math.atan2(fx, -fy) + math.pi) * (180 / math.pi);

    I plan to use the compass as a joystick along with an accelerometer. So GPS is not suitable for me, but I need stable determination of the deviation of the phone from the magnetic pole.

    are macros still working for you?
    when I type this simple macro gideros complains!
    PLAYER @ 1
    BOX @ 2
    Weird >:)
    EDIT: PLAYER seems to be reserved, I changed to PLAYER1, all good :)

  • i tried to export my app for html5 and it gives the error:
    "falling back to ArrayBuffer instantiation"

    @keszegh, enable compression and it should work.

    in gideros installation folder \Library\3dbase wouldn't it be better to replace 3DObjLoader.lua (5kb) by objloader.lua (9kb). I don't seem to make 3DObjLoader.lua work for obj. objloader.lua works great.

    I see gideros 2020.02 is coming :) could you please comment on the above? Thank you.

  • hgy29hgy29 Maintainer
    Yes, I will compare both to be sure though
  • hgy29hgy29 Maintainer
    Ok, I checked both version, and it appears that 3DObjLoader is actually much more advanced than objloader.lua, but they don't have the exact same API

    I think you mean the opposite: objloader.lua is actually much more advanced than 3DObjLoader ? For me objloader.lua works fine even with reactphysics3d. I tried to push it on github but I couldn't find the library folder!

  • hgy29hgy29 Maintainer
    No, I really mean 3DObjLoader is better: it handles polygon surfaces (not just triangle). It is lower in size because most of the work is now shared across multiple importers. It lacks a few texture options though, I can add them.
  • ok I will try it again then! when I do:
    -- an object
    --local patrick = loadObj("3d_objs/Patrick Star", "patrick.obj", "3d_objs/Patrick Star/Tex_0086_2.png")
    local patrick = loadObj("3d_objs/Patrick Star", "patrick.obj")
    I have this error:
    stack traceback:
    3dbase/3DObjLoader.lua:54: in function 'parsemtl'
    3dbase/3DObjLoader.lua:147: in function 'importObj'

    Ok, I see, I will fix that. meanwhile, just add an empty string parameter to the call of importObj near the end of 3DObjLoader.lua:
    local root,mtls=importObj(path,file,imtls,"")
