Simple example:
On Trigger (key pressed, mouse klick, whatever)
+ repeat X times (how many particles you want to have)
= Create (Particle) on Layer(what you want) at X: random(LayoutWidth), Y: random(LayoutHeight)
(So the particles will be created anywhere on the screen. But you can create them where you want)
The Particles have Bullet-Movement with Speed:0, Acceleration: 500, Set Angle: No.
For each (Particle):
= Set Bullet Angle of Motion to angle(Self.X, Self.Y, Player.X, Player.Y)
(so the Particles always follow the "Player-Object")
When (Particles) overlaps (Player)
= (Particles) destroy
