Did you try adding "my.STATE = 1;" in the part of the jumping?
if(grounddist-minv(movedir.z*time_step, grounddist) == 0)
{
//jump
movedir.z = -jumpacc;
my.STATE = 1;
}
If that doesn't do the trick, try to rebuild the code from scratch, thinking about what is the beginning and what is to be add next, adding one thing at a time, testing, add another, testing, and so on.
