I’m using this script to move an object. sometime it work, sometime not, it move curve, refer to pic

ang = Math.atan2(yy-pass.\_y, xx-pass.\_x);  
if (pass.\_x\>xx || pass.\_x\<xx) {  
pass.\_x += Math.cos(ang)\*spe;  
pass.\_y += Math.sin(ang)\*spe;  
}

some time it move to b to c first (the curve line) then only to a, i want it move from b to a , is a straight line. how come this happen? thanks for helping
