Position is relative to the sprite's
parent, as well as its
anchorPoint generally ranges from 0 to 1 for each coordinate, with a default of 0.5. I say "generally" because it can really be any value, but ranges outside of 0-1 place you outside of the bounds of the sprite.
For example, an
(0,0) makes positions relative to the bottom left.
(1,0) is the bottom right,
(0,1) is the top left and
(1,1) is the top right.
(0.5,0.5) is the very center of the sprite, which is the default.
Basically you just multiple the value by the width to get the relative position.
If you want to place a sprite at the very bottom of the screen (the bottom left corner aligned with the bottom left corner of the screen), you can do it multiple ways, based on the
With the default
(0.5,0.5), the position would be
If you set the
(0,0), the same position is obtained by simply
If you wanted to move that sprite to the very center of the screen (the center of the sprite right in the middle), with an
(0.5, 0.5), the position would be
This is all assuming you are adding a sprite to a parent the size of the screen, which is where the 2nd part of positioning comes in.
Position is also relative to the sprite's parent - which could be any other
The way to think of that is not much different than adding a full screen node - except think in terms of the parent's size and position, not the screen.
