Assume the following positions [with A being char 1 (with a non-reach weapon) and B being char 2 with a reach weapon and X being empty squares]:
A X1 X2 B
It's A's turn, he charges (which he can as he's >10 ft away), but B gets an Attack of Opportunity (AoO) as A attempts to leave X1 and as his attack-roll beats his CMD he manages to trip A.
Does this mean A's turn is over (besides any free or swift actions) or can he "recycle" the components of the charge action, for example into a move action to get back up, or to crawl next to B (either of which of course provoke AoO again, if B has Combat Reflexes or such)?
Info from a related question - here in the comments it's claimed that A would get to continue differently, but the SRD quote "Assuming he is still capable of doing so, he continues his actions once you complete your readied action." just talks of continuing his actions, not that he gets to change them, and laying on the ground he wouldn't be able to "continue his actions", as his actions were a charge, right?
