About settings for cocos2d-x coordinates and locations

The coordinate in 1.cocos2d-x (0,0) is the lower-left corner of the run box, so the Run box looks like a first quadrant.

2. The anchor point of the node is the position set by our setposition, the default anchor point is at the center of the node, that is, the coordinates set by the SetPosition method, such as SetPosition (VISIBLESIZE.WIDTH/2, VISIBLESIZE.HEIGHT/2) is to put the picture in the center of the Run box.

3. If you want to change the anchor point, you can use the Setanchorpoint method to set, Setanchorpoint coordinates are the node (picture) as a relative coordinate system, such as Sprite->setanchorpoint (0,0), is to set the anchor point in the bottom left corner of the sprite node, this time if Sprite->setposition (0,0), the picture will be placed in the bottom left corner of the Run box.

The 4.sprite->getcontentsize () method is to get the size of the sprite node, which is a Vec2 type of value, with the width and height properties.
