Particle Effect Display Halp

So ive been using DarkeeBlade12's Particle Effect Lib and Relection Util and i would love some help on displaying said Particle Effect, i know you must do ParticleEffect.REDSTONE.display(); but i am having trouble on the parameters what would be the best way to display the particle?

To show a basic effect

Code:

ParticleEffect.NAME.display(float offsetX, float offsetY, float offsetZ, float speed, int amount, Location center, double range);

// offsetX, Y, and Z are the distance that the particles can go away from the center.
// speed is the speed that they travel
// amount is the number of particles
// center is the location of where they spawn
// range is distance away from center that they can be seen
// instead of range you can put List<Player> of who can see them

To shoot particles in a direction

Code:

ParticleEffect.NAME.display(Vector direction, float speed, Location center, double range);

// direction is where they will go
// speed is how fast they will go
// center is where they will spawn
// range is how far away from the center they can be seen
// range can also be replaced with List<Player> of who can see them

I hope that may explain each parameter.
