Code:
                    var/obj/waterwave/I = new /obj/waterwave
                    var/obj/waterwave/K = new /obj/waterwave
                    var/obj/waterwave/J = new /obj/waterwave
                    if(src.dir == NORTH)
                        I.loc  = locate(usr.x,usr.y,usr.z)
                        K.loc  = locate(usr.x,usr.y,usr.z)
                        J.loc  = locate(usr.x,usr.y,usr.z)
                    if(src.dir == SOUTH)
                        I.loc  = locate(usr.x,usr.y,usr.z)
                        K.loc  = locate(usr.x,usr.y,usr.z)
                        J.loc  = locate(usr.x,usr.y,usr.z)
                    if(src.dir == EAST)
                        I.loc  = locate(usr.x,usr.y,usr.z)
                        K.loc  = locate(usr.x,usr.y,usr.z)
                        J.loc  = locate(usr.x,usr.y,usr.z)
                    if(src.dir == WEST)
                        I.loc  = locate(usr.x,usr.y,usr.z)
                        K.loc  = locate(usr.x,usr.y,usr.z)
                        J.loc  = locate(usr.x,usr.y,usr.z)


Problem description:
I got everything coded right, no errors, but i tried edit the x and y a million times and can not put in correct direction. At first i thought it might be like X and Y chart, where x is left to right and y is up and down. Can anyone explain or help me it suppose be one tiles ahead of usr and 3tiles wide.

1. You prolly want src.
2. Your x,y assumption was correct. Right now they're all be created under you.

Yeah but thats under the usr only. I want it shoot on left,under usr and right. If not that let it shoot a tile ahead on left and right.(This jutsu consist of 3tiles wides.)

locate(usr.x,usr.y,usr.z)

This bit here is your problem. What this does is return the turf under usr. What you need to know here is that x, y, and z are numerical values, this means that you can say usr.x + 1 to get one tile right of usr, and usr.y + 1 to get one tile above usr. Put all of this together, and it you can do things like this:

locate(usr.x-1,usr.y+1,usr.z)

This line returns the turf to the northwest of usr.

locate(usr.x-1,usr.y+1,usr.z)

Okay this is how i look at it, x-1 is to left of user and 0 which is x is under user, and x+1 is to right of user. So how i make it shoot 1tiles ahead of me.

Only one i got to work is South.
locate(usr.x-1,usr.y+1,usr.z)
locate(usr.x,usr.y+1,usr.z)
locate(usr.x+1,usr.y+1,usr.z)
