Phsyics crash: Intersecting shapes

[AggrorJorn]

The following code sample will run just fine. However when we uncomment the "SetGravity command", the game will crash.

 

 

#include "App.h"
using namespace Leadwerks;
App::App() : window(NULL), context(NULL), world(NULL), camera(NULL) {}
App::~App() { delete world; delete window; }
Model* ground;
Model* box1;
Model* box2;
Material* groundMaterial;
Material* stoneMaterial;
bool App::Start()
{
//Create a window
window = Window::Create("_3_Shapes");

//Create a context
context = Context::Create(window);

//Create a world
world = World::Create();

//Create a camera
camera = Camera::Create();
camera->Move(0,2,-5);

//Create ground and paint it with material
ground = Model::Box(10,0.1,10);
groundMaterial = Material::Load("Materials/tile2.mat");
ground->SetMaterial(groundMaterial);
Shape* groundShape = Shape::Box(0,0,0 ,0,0,0, 10,0.1,10);
ground->SetShape(groundShape);
groundShape->Release();
//Create a box
box1 = Model::Box();
stoneMaterial = Material::Load("Materials/stone2.mat");
box1->SetMaterial(stoneMaterial);
box1->SetPosition(0,2,0);
Shape* boxShape = Shape::Box();
box1->SetShape(boxShape);
box1->SetMass(1);
boxShape->Release();
// Create a second box
box2 = Model::Box();
box2->SetMaterial(stoneMaterial);
box2->SetPosition(0,1,0);
Shape* box2Shape = Shape::Box();
box2->SetShape(box2Shape);
box2->SetMass(1);
box2Shape->Release();
///BUG////
//box2->SetGravityMode(false);

return true;
}
bool App::Loop()
{
//Close the window to end the program
if (window->Closed()) return false;

Time::Update();
world->Update();
world->Render();
context->Sync(false);

return true;
}

I also get this error when using an array to create many boxes. Something goes wrong when objects intersect. The following program again runs fine. However, when you swap the bug line in the for loop, the programm crashes because objects are intersecting.

 

#include "App.h"
using namespace Leadwerks;
App::App() : window(NULL), context(NULL), world(NULL), camera(NULL) {}
App::~App() { delete world; delete window; }
Model* ground;
Model* boxes[100];
Material* groundMaterial;
Material* stoneMaterial;
bool App::Start()
{
//Create a window
window = Window::Create("_3_Shapes");

//Create a context
context = Context::Create(window);

//Create a world
world = World::Create();

//Create a camera
camera = Camera::Create();
camera->Move(0,2,-5);

//Create ground and paint it with material
ground = Model::Box(10,0.1,10);
groundMaterial = Material::Load("Materials/tile2.mat");
ground->SetMaterial(groundMaterial);
Shape* groundShape = Shape::Box(0,0,0 ,0,0,0, 10,0.1,10);
ground->SetShape(groundShape);
groundShape->Release();
ground->SetFriction(0, 10);
stoneMaterial = Material::Load("Materials/stone2.mat");
//Create an array
Shape* tempShape = Shape::Box();
for(int i = 0; i<100;i++)
{
 // Create a second box
 boxes[i] = Model::Box();
 boxes[i]->SetMaterial(stoneMaterial);
		    /// BUG
 boxes[i]->SetPosition(0, 5 + (i * 0.2),0); //Crashes
 //boxes[i]->SetPosition(0, 5 + (i * 1.2),0); //Works fine

 boxes[i]->SetShape(tempShape);
 boxes[i]->SetMass(1);
}
tempShape->Release();
return true;
}
bool App::Loop()
{
//Close the window to end the program
if (window->Closed()) return false;

Time::Update();
world->Update();
world->Render();
context->Sync(false);

return true;
}

Yes that error also happens when using the editor without coding :

You place models that have physics and they intersect in the editor.

When running the game the error will make the game crash.

 

Could it be possible to have LE3 display a warning in the editor ?

Newton 3 is filled with error checks and it's quite excessive. I did a full project search and replace to get rid of these, which can occur during physics updates.
