I don't know about that F1:... thingies but here is solution:
1)Create a new char.(You can copy any fighter)
2)Make that's dvy: 2000 in that's jump frames.
3)Make that's next: "the frame of object creation" in that's crouch frames.
4)Prepare the "frame of object creation".(Add your opoint of object)
5)In "frame of object creation"; before opoint, give it a dvx:999 to stick it into a side of screen.
6)Then make that frame's next:1000
7)Make the perspective: "The id of the char".
8)Also make the used frames of the char; pic:999 to make it invisible.
Step 1,2 and 3 is necessary for performing an action on the ground.
Because perspective tag opoints the id on the up-screen.
For z-placing a new ball creation needed.
I don't have time to explain that
And also you can investigate my
Teleporter Machine's(in Projects section) summoning style to understand...(z-placing is applied there)
I wish it helps...
