 return objects [obj] [floor (att)] [1+((att - floor (att)) * 10)] -->ERROR

{
                {1,0,{},{ 0, 0},{639,479}, 1,1,1},
                {1,0,{},{10,10},{459,459},-1,1,1}

I changed the line to read:
    return objects [obj] [floor (att)] [1+((att - floor (att)) * 1)] -->ERROR

I get the result {10,10}

att-floor(att) is .1 which you are trying to turn into a 1 by multiplying
by 10 but I suspect that Euphoria is expecting is an integer -- sure enough
In the manual I found:

"Non-integer subscripts are rounded down to an integer"  so Euphoria is
seeing that last element number as [0] and not [1]
