it still is not working . this is the main problem the total position is changing when i add a new keyframe . (or i need to first add the keyframe in the same spot and then adjust it so the ball move to the position but that aint really easy .
this are a few pictures to show what i mean .
this is what i did at the start (before i place a new keyframe . )

and once i put it at the new place the line is placed at a diffrent spot .

i really have no idea what i did wrong but i hope somehow this could be fixed . its not like i am that far but i still keep hoping it can be fixed and i dont need to restart from 0 .
i tryed to adjust the handel from free to automatic and vector but that is not solving the problem .
the reason its a basket ball and not the bowlingball is because i did not pushed reload trusted .
