Changing the Sprite Position
The Scratch is 480 pixels wide and 360 pixels high. Everything is on a grid with two axes-x
axis and y-axis.
x-axis : A horizontal line that marks left and right positions; ranges from –240 (farthest
left) to +240 (farthest right).
y-axis : A vertical line that marks up and down positions; ranges from –180 (lowest) to
+180 (highest).
The default position of sprite is at the point where the x-axis and y-axis meet called origin
(X: 0, Y: 0).
As we move to the right from the origin, the x-value increases from 0 to 240. As we move
left from the origin, the x-value changes from 0 to -240. Similarly, as we move up from the
origin, the y-value increases from 0 to 180.
As we move down from the origin, the y-value changes from 0 to -180.
