Helpers and Projectiles in 1.1 support an undocumented postype of `none`. With postype set to `none`, the Helper or Projectile will be spawned offset from the stage center. This postype option was documented for Explods, but was missed in the documentation for Helpers and Projectiles, despite being functional.This is also the only postype option which breaks this rule from the post: "In all cases, off_y is relative to the position of the player". In the case of `postype = none`, off_y is relative to y = 0 (i.e. the floor of the stage).
Helpful little tip, from a Noob 4 Anyone. I have recently been experimenting with making stages for Ikemen Go and ran into an issue with the attached character Feacher. A helper would keep moving around when I reset the stage or skipped the intro. The way that I fixed this issue was to put the postype as 'None' as suggested by Ziddia. (Thanks Ziddia!) Hope this will be helpful to someone.
