DestructMesh element out of range

Hi Greg,

Probably i found bug in:

Code:

DestructMesh& create(Mesh &mesh, Int cuts, C MaterialPtr &material, Flt tex_scale=1, Int phys_vtx_limit=-1, Bool cut_affects_biggest_part=true, Bool simple_cuts=false);

This method sometimes generate parts out of range, for example if we want 8 cuts, function generate 7 or 9 parts. This occurs randomly maybe one in ten cases or sometimes when i try build and test my application i see Error: _inline.h line 149

You can run this sample code which trying to create destruct mesh until generated parts parts will be different from defined cuts limit.

Code:

DestructMesh mesh_destruct;

MeshPtr      mesh;

bool         stop = false;

int          counter = 0;

void InitPre() 

{

   EE_INIT(); 

   Physics.create(EE_PHYSX_DLL_PATH);

}

bool Init() 

{   

   mesh = ObjectPtr(UID(1134879343, 1157937325, 4232119955, 3140023117))->mesh();

   return true;

}

void Shut(){}

bool Update() 

{

   while(!stop)

   {

      mesh_destruct.del();

      mesh_destruct.create(*mesh, 7, UID(2469699354, 1312990749, 9733255, 2328309462), 1, 32); 

      counter++;

      if(mesh_destruct.parts() != 8)stop = true;

   }  

   if(Kb.bp(KB_SPACE))

   {

      counter = 0;

      stop    = false;

   }

   if(Kb.bp(KB_ESC))return false; 

   return true;    

}

void Draw() 

{

   D.clear(TURQ); 

   D.text (0,   0, S + counter + " : generated parts = " + mesh_destruct.parts() + " / 8"); 

   if(stop)D.text (0,   0.2, "Press SPACE to reset");

}

Hi,

Maybe just the cuts don't guarantee creation of new parts, for example if for a random slicing plane all mesh is on one side, then there won't be any mesh slice operation.

I'm assuming that the out of range error happens in your own codes?
I think it's better approach to not assume you will get 8 parts.

Aaahhh oookkkk,

I thought the cuts limit always cut my mesh specified number of times. That explained all.

Sory for confusion.
