1,084 PointsinBounds/outOfBounds: why if the Y = Height does it become outofBounds and not inBounds?
why if the Y = Height does it become outofBounds and not inBounds? Why isn't Y <= Height techincally inbounds?
Same goes for outOfBounds = point.X >= Width

Courses Plus Student 7,028 Points"zero base counting" rule:)
However, in programming, by convention we start counting from zero.

This means that the point on the bottom left corner of the map is 0.00.
3:36
And the rightmost point has an x value of one less than the width.
3:42
The topmost point has a y value of one less than the height.
3:47
This is called zero base counting.
3:50
This throws a lot of people off.
