Walk togheter

[fiaschetta]

I have three character that must to walk on coordinates X:50 Y: 100. 
I want that they walk togheter.   
With this script 
 

Code: ags

character[MARK].Walk(399, 287, eBlock);
character[JO].Walk(399, 284, eBlock);
character[MAT].Walk(399, 287, eBlock);

 
First Mark walks.. and  when he on X:50 Y:100 
JO begin to walk... then Mat   
 
But I want that they walk together..

eNoBlock instead of eBlock for the first two.
