array manuvering bow scirpt help, help please!

[prozac424242]

Hi there, this NPC i have been working for a customizale board
does not quite qork right. Instead of all of the arrows showing up,
i would like it so that one arrow shows up on its own x and y each time it is fired. any tips, knowledge and help would be great. For each time you fire another arrow starts on its own and any y and the other arrows keep going til they hit a wall, that is the goal.
