Making a boss shoot projectiles around itself

So i was starting to make my mod’s third boss (Venus Slime), but i quickly ran into a problem.
 You see, i wanted my boss to shoot six projectiles around itself, kind of like this.

 But since i’m relatively new to MCreator, i don’t know how to do that.

 So, i’m wondering if it is possible to make my boss shoot 6 projectiles around itself in the x and z axis, each separated by 60º.

Kind of like this.
