Pen Particles

This tutorial will show how to make pen particles. These are often used as background or death effects in many games.

Adding Particles to a List

The first step to making pen particles is making a list of particles as a 2D array, each particle will have more than one item on the particles list. First, a list needs to be created, called particles:

Now, a script that adds a particle at a certain x and y position with a certain x and y velocity.

Deleting Particles

Now a script needs to be created to delete a particle at a certain item on the particles list:

Rendering Particles

A script will also be needed to render the particles that are already stored in the particles list:

Updating the Particles' Positions

This script moves the particles around:

Implementing The Code

Now that all the scripts are made, they must be used. Depending on the type of program wished to make, one may want to make mouse effects:

Or one can make background effects:
