# AB-Particles Particle System
**V1.1.0 now out with new settings and features.**
AB-Particles is a particle system I designed for the 8-bit gaming platform, the [Arduboy](https://www.arduboy.com/). However, it can be ported to other platforms with ease. I probably will end up porting it to the ESP32.
A simple `.ino` file is included for a demo of the particle system, and it's use.
(Default settings shown above. The "explosion" can be altered by the user)
## Features
AB-Particles is a simple, minamalistic approach to a particle system.
Currently, it has the option for either square or circular particles, and an option to have filled or "outlined" particles.
Square (not filled):
Square (filled):
Circular (not filled):
Circular (filled):
Each particle also has a set lifespan/lifetime, where after the lifespan of a particle is over, the particle will disapear. The lifespan of a particle is pseudo-randomly generated, leading some particles to disapear earlier than others for a nice effect.
A horizontal and vertical force (which are added to the particle's velocity) is also pseudo-randomly generated (but restricted by a limit defined by the user) meaning each and every time you reset (and update + render) the particles, you'll have an entirely new effect.
Bigger particles (defined by `size`) will also fall faster than smaller particles, giving the "explosion" a realistic feel.
You can also define how many particles you want. (30 by default).
Settings are configured inside the `User-Setup.cpp` file.
One setting is also available in `User-Setup.h`, however most will not need to change it unless they have memory concerns regarding their program.
## To Use:
To utilise AB-Particles in your project, you must include the `AB-Particles.cpp` and `AB-Particles.h` files (available above in the `src` folder) in your project directory.
From then, make an object of the class `Particles` called `particles`, as `particles` is `extern`ed in the header meaning it is known throughout all your project files. Same thing with the `Arduboy2` class, so you should call your `Arduboy2` object `arduboy`. If you have any confusion regarding this step, feel free to check out the demo included.
Note that in order for the `random()` function to work properly, you must seed it with the `Arduboy2` function, `initRandomSeed()` in `setup()`.
As mentioned above, you can change and configure values/settings in the `User-Setup.cpp` file.
### Functions
AB-Particles includes three functions: `reset(float x, float y)`, `update()`, and `render()`.
`reset(float x, float y)`: Randomizes each particle's attributes in the array set, and takes an x and y coordinate for each particle's position (world space or camera space depending on what you input to the function).
`update()`: Updates each particle per frame.
`render()`: Renders each particle per frame.
