i have this code of the array of grouped object which of the last follows the object just before, and the first object has its movement in ramdom. These objects appear when key are typed. But I want to split it into several groups when space bar is pressed,so that each time just the type after the space bar has its movement, and the keys before the space bar becomes as a group. but I dont know how to do that. I tried but not working. PLS help me . Thank you.

if you go to this link, i uploaded the code which is not spliting effect with space bar. to start up, you should type the keyboard.

Below i will post the code that i tried to make it split into differnt groups but i failed.


.....
 
 for(int sl=1; sl<seq_length; sl++){
 keynow[seq_length]=key_lengthtt;
 key_length=key_lengthtt-key_lengthc[sl-1];
 i=keynow[sl]-keynow[sl-1];
 for(int i=0; i<key_length; i++){
 float dd = dist(loc_x[i],loc_y[i],
 loc_x[(i+1) % key_length],loc_y[(i+1) % key_length]);

....

What i tried to do is to make a group of sequences among the array, but i think i am just not clear how to do it. Could you give help? Thank you.
