Dear,
Thanks for you reply! Here is you information:
1/ My intent like Tower Defense => How you call it? - In think it top-view.
2/ The monsters i have add 8 direction, and bound to layout (to check when they meet).
3/ no monster in my control, i just tap to spawns it and then he come to target.
4/ bound to layout (to check when they meet but it fight one ).
5/ Yes it does
6/ If A monster come to castle A => B win, and monster A come to castle B => A win.
thanks for your help
