SPHOME
Root / Documentation / [.]
Set or get a sprite's home coordinate (transform origin.)
The home coordinate is used as the origin (center point) for
SPOFS, SPROT, and SPSCALE. Additionally, the home coordinate is used as the origin for sprite collision, and the start point of the default collision box in SPCOL (if a collision box is not specified.) The home coordinate is specified relative to the sprite's upper-left corner, e.g. the center of a sprite is width/2, height/2.
If the sprite was set using a definition template, its default home coordinate is set by the template. Otherwise, it is 0,0, or the sprite's upper-left corner.
