Fireballs and Vectors?

Hey, I'm making a simple plugin that shoots fireballs when you right click an item, and then removes the item. It all works just fine, but it seems that spawning more than 1 fireball in the same location causes them to collide with each other and explode before touching the ground. I'm pretty sure my only two choices are to create a delay between each time a fireball is spawned, or move the locations of where the fireballs spawn. I want it to be instantaneous so that the player can click and then turn without affecting the fireball launch trajectory, so I need to find a way to put the fireballs at different points along the vector(the player's sight line). Is there a simple way to do this, or would I be better off doing the delays? Also, is there any other way to prevent the fireballs from exploding before hitting the ground?

(^If that doesn't make sense I'll try to clarify ^)

Thanks for any help!

Store the location prior to creating the runnable, then use that location in the runnable so the player's movement doesn't change it at the time
