Hello IAA_Agent,

There are a couple of issues with your code. The first group of errors, your Vector2 knightPos declaration has an extra } that is telling the compiler that your code’s scope is ending before it should (it thinks that the main function ends when it shouldn’t). You should also be using a comma to separate that two initializing values for Vectors, instead of semi-colons. Lastely, you need to add a semi-colon to the closing bracket of this initialization. The result should be this:

Vector2 knightPos{
        (float)windowWidth/2.0f - 4.0f * (0.5f * (float)knight.width/6.0f),
        (float)windowHeight/2.0f - 4.0f * (0.5f * (float)knight.height)
};

The next group of errors is with these two lines:

    Rectangle source{0.f, 0.f, (float)knight.weight/6.f, (float)knight.height};

    Rectangle dest{knightPos.x, knight.Pos.y, 4.0f * (float)knight.width/6.0f, 4.0f * (float)knight.height};

Texture2D does not have a property called weight, and I believe you had meant width. Texture2D also does not have a Pos property, which again I believe you meant knightPos.y. The resulting changes would look like this:

Rectangle source{0.f, 0.f, (float)knight.width/6.f, (float)knight.height};
Rectangle dest{knightPos.x, knightPos.y, 4.0f * (float)knight.width/6.0f, 4.0f * (float)knight.height};

Your code tested with these changes produces no errors. I hope this helps!
