    I'm experiencing random crashes on Android which seem to originate from OverlapBox call.
    For example:
    Code (csharp):

    36.  

    I'm investigating the issue at the moment, but has anyone else experienced this kind of problem?

    The issue is random and cannot be reliably reproduced.

    Unity version 5.3.3f1

    Alright. Despite my attempts to eliminate every possible cause of the issue, and implementing object pooling, the problem refuses to disappear. After multiple calls to physics.OverlapBox, application eventually gets killed by SIGSEGV, SEGV_MAPERR, with stacktrace within libunity.so which originates from one of OverlapBox call. No matter what I do, how I do, it just unavoidably dies.

    So I'll assume it is a unity bug that only manifests itself on android.

    The only remaining workaround for this is replacing physx overlapbox collision queries.with custom collision system.

    (sarcasm)Yay(/sarcasm).

    I'm already made a game for Android/IPhone and WPhone. Android was the most convenient, WPhone was painful.

    1. At first, connect with adb and put that output inside this forum. (The last lines, not all the dump :) )
    2. The biggest problem was the memory allocation, Android with 500MB RAM just allow allocating max 180MB. If you are on the limit, crashes happens.
    3. Custom ROMs are not supported, however this was never a problem for my custom ROMs.

    #00 pc 00000000 <unknown>

    Seems to be a null pointer access, could be caused by not getting more RAM from the OS.

    What specifically are you looking for? Because I have dozen of crashlogs 1 Mb each with loads debug data printed in them. There's no discernable event before the crash, except that ALL the crashes happen within "overlap box".

    I wrote my own collision system and replaced Physics.OverlapBox with my own function.

    Have not experienced any crashes since then. Collision queries take a bit longer, but the program does not die randomly anymore.

    So, it is a physx bug, specific to android.

    The Physics.OverlapBox method is quite new in Unity, I had have to write my own solution with OverlapSphere. Probably OverlapBox is broken. I guess Unity's code looks very similar, because a sphere check is very fast and I guess even with the overhead this solution would be faster than a 'real' box check.

    Code (CSharp):
    1. public static List<Collider> OverlapBox2(Bounds bounds, int layerMask) {
    2.         Vector3 center = bounds.center;
    3.         Vector3 onePoint = new Vector3(center.x + bounds.size.x / 2, center.y + bounds.size.y / 2, center.z + bounds.size.z / 2);
    4.         float radius = Vector3.Distance(center, onePoint);
    5.  
    6.         List<Collider> inBox = new List<Collider>();
    7.         Collider[] hitColliders = Physics.OverlapSphere(center, radius, layerMask);
    8.         foreach (Collider col in hitColliders) {
    9.  
    10.             if (bounds.Intersects(col.bounds)) {
    11.                 // Inside box
    12.                 inBox.Add(col);
    13.             }
    14.         }
    15.  
    16.         return inBox;
    17.     }
    If this doesn't crash for you, then there is a high probability that the OverlapBox is broken.

    The adb output shows the state of your device, also shows the errors, the warnings, what tasks running, what tasks are closed to run your application and much more.

    We encounterd the same problem for Physics.OverlapBoxNonAlloc() on 5.3.5p1 and 5.4.0f2.
    It must be broken!

    Hi. We have same problem on 5.3.4p1.
    Did anyone posted a bug with this?

    It's been a long time ago, so I forgot if I filed a bug regarding this one. Feel free to do it yourself.

    As I said, in my case I rolled out replacement collision detection system which supported OBBs and nothing more.

    I have found a crash with Physics.OverlapBoxNonAlloc() in android, but I have not seen the crash with other Physics.OverlapBox(), is it related with the NonAlloc version or it can be happening in both alloc and non alloc?

    It happens with both. I've just run into this myself, I assumed it was due to a long ass algorithm for generating a dungeon, so I broke it up into signals and commands (I'm using StrangeIOC), that helped a little, but it still happens when the dungeon generation has to grind a bit longer. I've also tried yield returning if the path has been blocked, etc etc.

    I tried switching to non-alloc version of overlap box, and it did seem to reduce the crash, but it still did happen eventually. It's like the algorithm just isn't releasing memory, so every time you call it, it's adding up and adding up.

    I also should mention, I'm using beta 5.6.0b9, but it seems that doesn't really matter for this case.

    BTW: It has NEVER happened in Editor, just on Android, both on a Pixel, and an older Droid XT1080.

    I'm seeing the same issues with Physics.OverlapCapsuleNonAlloc.

    I have filed a bug about it, but no test project with it unfortunately

    Bug Report below, no Issue Tracker ID yet:

    -----------------------------------------------------------------------------------------------------------------------

    Hard crash on Android due to Physics.OverlapCapsuleNonAlloc

    1. Hard crash on Android due to Physics.OverlapCapsuleNonAlloc()


    2. Unfortuantely, I can't attach our project and have not been able to reproduce in a simple test project.

    The problem pretty much occurs on every run through of the game provided we play for a few minutes. When it happens appears to be random.


    3. I am using Physics.OverlapCapsuleNonAlloc() by passing the position of the bottom capsule sphere first, followd by the top sphere. The radius is 0.49 units. The capsule height (total) is 1.47 units. I call this every frame on my player character object.

    The buffer foir the overlapping objects is declared as:

    Collider[] depentrationResults = new Collider[10];

    Generally, only 1 or 2 elements in the buffer are required/used.

    I set the individsual elements of the buffer all to nulll each frame before I call Physics.OverlapCapsuleNonAlloc() in orde to reset them.

    I'm having this problem on Android as well, using Unity 5.6.0f3. Seems like a pretty fundamental problem.

    Thank you very much for posting this code.

    I used it to reimplement the OverlapBox API that is broken. It uses an OverlapSphere to get the nearby colliders, and then uses your BoxBox algorithm to see if the box collider is touching the other collider. The other collider is assumed to also be a box collider, if it is not, the collision will not be accurate (it will use the other colliders transform localScale as the box extents).

    Also, I'm relying on this mental calculation I made that the Sphere that fully encompases a box will have a radius of:

    var radius = 0.5f * new Vector3(boxWidth, boxHeight, boxDepth).magnitude;


    Someone please let me know if I'm wrong there. EDIT: I have since confirmed this to be true.

    Here's my blog post about the workaround.

    Here's the code that reimplements OverlapBox.
    It's very fast and is built on top of Bunzaga's collision detection. It works correctly for BoxColliders, and almost for Sphere Colliders. If you need accurate results against Sphere Colliders, update the position and halfExtent calculations with specific code for Shere Colliders.

    Code (CSharp):

    9.     private static Vector3 _AX = new Vector3(); // A Axis
    10.     private static Vector3 _BX = new Vector3(); // B Axis

    13.     private static Vector3 _v2 = new Vector3();

    17.     private static float[] _bRot = new float[9];
    18.  
    19.     private static float ar = 0.0f, br = 0.0f;
    20.

    We are seeing the same thing it seems with overlap capsule. Switching to overlap sphere seems to fix it. But after reading some of these forums I wonder if it won't show up again.

    iOS and editor do not have this problem.
    Both versions of unity 2017 have the problem on android. Tried on several android devices with various os versions.
    All seem to crash randomly.

    Yeah I noticed that OverlapCapsule/CapsuleCast/CheckCapsule are all broken on Android as well. Though they seem to show up on some < 50% of calls.

    Certainly an annoying, long standing problem. I wonder if there's a bug number we can track yet.

    Thanks for the sample code.
    A few notes:

    - This should probably be collider.bounds.center or collider.transform.TransformPoint(collider.center)
    - The non box approximation could use nearbyCollider.bounds with the identity rotation
    - nearbyCollider.GetComponent<BoxCollider>() should be nearbyCollider as BoxCollider in case there is more than one collider in the gameobject
