Formula to split screen in 4 diagonal zones

Questions & Answers
1

I need a formula to split the screen into 4 pieces. From the top left corner to the bottom right one and from the bottom left corner to the top right one. So they are diagonaly split.

if (m_MousePositionX * m_pythagoras < m_HalfScreenWidth && m_MousePositionY * m_pythagoras < m_HalfScreenHeight)

etc…
Still cant get a correct formula after couple of hours
As you can see i try to call functions depandend on where my mouse position is (Left, top, right or bottom zone of the screen)

Try this:

// Convert mouse cursor pos to normalised range: -1 to +1
float x = (m_MousePositionX-m_HalfScreenWidth)/m_HalfScreenWidth;
float y = (m_MousePositionY-m_HalfScreenHeight)/m_HalfScreenHeight;

if (Mathf.Abs(x) > Mathf.Abs(y))
{
    if (x>0.0f)
    {
        // right
    }
    else
    {
        //left
    }
}
else
{
    if (y>0.0f)
    {
        // up
    }
    else
    {
        // down
    }
}

Vector3 ConvertMousePosToCardinalDirection(Vector3 m_MousePosition)

if (Vector3.Dot(m_MousePosition.normalized, Vector3.right) >= 0.5f)
    return Vector3.right;

else if (Vector3.Dot(m_MousePosition.normalized, Vector3.left) >= 0.5f)
    return Vector3.left;

else if (Vector3.Dot(m_MousePosition.normalized, Vector3.forward) > 0.5f)
    return Vector3.forward;

else
    return Vector3.back;

or you could do

Vector3 ConvertMousePosToCardinalDirections (float m_MousePositionX, float m_MousePositionY)

if (Mathf.Abs(m_MousePositionX) > Mathf.Abs(m_MousePositionY))
{
    if (m_MousePositionX < 0)
        return Vector3.left;
    else
        return Vector3.right;
}
else
{
    if (m_MousePositionY < 0)
        return Vector3.back;
    else
        return Vector3.forward;;
}

and change back to down, and forward to up as needed
