Re: Google Play New problem : 64bits

All right, I think I found the last culprit :lol: I was still initializing SunVox, even though there's no more music in the game, while waiting for me to finish composing the music (on FamiStudio, it's complicated). With SunVox entirely deactivated, it's been a good while since the game didn't rando...

Re: Google Play New problem : 64bits

Thanks. I found another error, but comming from me: <Bitmap Name="BitmapSpaceColors" Width="5" Height="1"> <Producers> <BitmapExpression> <Expression> <![CDATA[float c1 = cos(X + 1); float c2 = cos(X - 1); Pixel.R = NebulaeColor1.R * c1 + NebulaeColor2.R * c2; Pixel.G =...

Re: Google Play New problem : 64bits

Is it possible that setting Pixel.R (G or B) can crash if it's under 0 or over 1?

I'm still getting some scarce random crashes, so I started sanitizing everything, just in case.
For example:
Pixel.R = max(0, min(GroundColor[0][0,0] + offset, 1));

Re: 3D Physics with ZgeBullet

I tested every setting from rado1's ZGEBullet examples: Demo 1: float t = App.DeltaTime; zbtStepSimulation(t, 0, 0); Demo 2: float t = App.DeltaTime; zbtStepSimulation(t, 3, t/2); Demo 3: float t = App.DeltaTime; zbtStepSimulation(t, 1, t); Demo 4: zbtStepSimulation(App.DeltaTime, 0, 0); zbtStepSimu...

Re: Google Play New problem : 64bits

So I just tried the manual division per zero with SetExceptionMask deactivated, it doesn't change anything. The app is crashing in Android Studio, and running just fine on the real hardware. Nevermind :roll: I saw that you validated my commits, but I forgot to add the modification to avoid division ...

Re: Google Play New problem : 64bits

I just played Omeganaut for an hour without any crashes. The only two division-by-zero errors were due to BitmapExpression not handling bitmaps with a width or height of 1 on Android 64-bit in libzegandroid. A very specific issue and hard to track down... Normally, I'd let the user’s ZGE app crash o...

Re: Google Play New problem : 64bits

Even with that line (+ uses Math ) Android Studio doesn't appreciate the division per zero in OnUpdate. The real device doesn't seem to be affected. But it was crashing often before with the division per zero on the bitmap width. It behaves exactly the same without the addition of that line. <?xml v...

Re: Google Play New problem : 64bits

And the problem comes from Task.YStep := 1/(H-1); in procedure TBitmapExpression.ProduceOutput(Content : TContent; Stack: TZArrayList); var SourceB,B : TZBitmap; H,W,I : integer; Pixels,P : PColorf; TaskCount,RowsLeft : integer; TaskList : pointer; Task : PPixelTask; TaskH : integer; begin SourceB :...

Re: Google Play New problem : 64bits

All right, the problem seems to be coming from here: <Bitmap Name="BitmapSpaceColors" Width="5" Height="1"> <Producers> <BitmapExpression> <Expression> <![CDATA[float c1 = cos(X + 1); float c2 = cos(X - 1); Pixel.R = NebulaeColor1.R * c1 + NebulaeColor2.R * c2; Pixel.G ...

Re: Google Play New problem : 64bits

float x=1, y=0, z=x/y; doesn't seem to bother the phone, but it crashes on Android Studio if it is located in OnUpdate. It doesn't crash if it is calculated only once at start. Shouldn't this be handled by ZPlatform_Android.inc ? Math.SetExceptionMask([exZeroDivide,exOverflow,exUnderflow,exPrecisio...

Re: 3D Physics with ZgeBullet

I have a technical question regarding the update of the bullet simulation. I always used it like this: float t = App.DeltaTime; zbtStepSimulation(t, 0, 0); But the documentation is talking about: @fn void zbtStepSimulation( float timeStep, int maxSubSteps, float fixedTimeStep) @brief Proceed the sim...

Re: Google Play New problem : 64bits

I already asked this before , but is it normal that JNI_OnLoad isn't found at startup? It is defined in jni.pas function JNI_OnLoad(vm:PJavaVM;reserved:pointer):jint;{$ifdef mswindows}stdcall;{$else}cdecl;{$endif} const curVM:PJavaVM=nil; curEnv:PJNIEnv=nil; implementation function JNI_OnLoad(vm:PJ...

Re: Google Play New problem : 64bits

So I reverted every test I made for the last few days, and just added the modification to calculate XStep, and now the circles are fine. I'm going to play for a while and see if there are other surprises :wink: Edit: I played for a long while and only got it to bug once, the bug with the unhelpful m...

Re: Google Play New problem : 64bits

I may have found something!!! 8) In procedure TBitmapExpression.PixelTask(Task: pointer); XStep is calculated like that: XStep := 1/(T.W-1); But in Omeganaut, I have a texture with width = 1. Since it is stretched on the entire screen, I thought that it would prevent to calculate a lot of pixels fo...

Re: Google Play New problem : 64bits

Nope, that's not it... So I tried something else: In Android Studio, the old version of Omeganaut crash instantly with this message: 2024-10-25 16:22:47.539 11986-11986 DEBUG crash_dump64 A #01 pc 0000000000045fec /data/app/~~HS9PFsTspxTG-3gCY_1big==/com.txori.omeganaut-NAXMKI2-Q7qBcBbaqtxJrA==/lib/...
