# Particle System

Unity Particle System is a really useful tool in generating particle effects like explosions, explosion trails, tracers, smoke effect, etc.

Particle system aws used in this game to demonstrate a healing effect and for the intro and main menu to make the scene more interesting.


**Particle system in play to to demonstrate particles flting towarfds the scene**

The effect shown above is achieved through unity's particle system.
The properties tweaked to achieve this effet were:-
- Making the emmision over time as constant
- Shape of emmision was set to rectangle to match with screen shape
- Rotation and rotational speed over lifetime were also tweaked to give particles a the effect that they slow down whe reaching near the screen.

## How to setup your own effect.

1. Right Click in the **Heirarchy** window -> **Effects** -> **Particle System**.
2. You will see this kind of particle effect at first.
3. There is default sprite in the particle system.To change that go under Particle system -> Enable Texture Sheet Animation and set render mode to sprite and then assgin the sprite to the effect system.
4. Various settings inside the aprtilce system can be tweaked to get the desired output such as particle's lifetime, velocity, angle, rotation, etc.
