Graphics / sf::Transform.Translate not moving the object

« on: November 10, 2014, 02:55:10 am »

I have created my own function for translate as

void Transform::Translate(sf::Vector2f deltaPosition)
        {
                Position.x+=deltaPosition.x;
                Position.y+=deltaPosition.y;
                positionMatrix.translate(deltaPosition);
        }

but it doesnt work at time
From my physics class if I call this as

gravity = sf::vector2f(10,0)
transform->Translate(gravity)

it works
but if I call it as

position = gravity/mass*dt*dt;
transform->Translate(position);

it doesnt works
Any idea where I might be wrong ?
I have checked the values for delta position and I am getting proper values in there
but still the object is not moving

}

This is the code i am trying to run everything works fine
but when I try to run it i get an error saying "Unhandled exception at 0x75a6f7cc in board render tes.exe: 0xC0000005: Access violation reading location 0x65742064.".
previously i was able to run the projects of sfml
no such error occurred.
now also i use the old projects and just write the code in them and works perfectly fine but if i make any new project i get this error.
please help me to solve this error

int main()
{
        float f=0.5;
    Clock Clock;
    while (Clock.GetElapsedTime() < 5.f)
    {
        std::cout << Clock.GetElapsedTime() << std::endl;
        Sleep(f);
    }

    return 0;
}

this is the code I am using and i am getting a runtime error
"The application was unable to start correctly (0x0150002),Click Ok to close the application."
