This section focuses on Unity's powerful particle system. In this video we overview the topics we'll be covering throughout the section.
The first 3 properties we will look at for particles include Emission, Energy, and Size.
We now move on to the linear properties of particle movement, both global and local.
We now look at tangent velocity, which moves particles along a surface, and angular velocity, which causes particles to spin.
This video sums up any remaining properties for the ellipsoid emitter that have not yet been discussed.
The Mesh Emitter is essentially the same as an Ellipsoid Emitter, with a few property differences, which we discuss in this video.
In this video we begin looking at the properties of the Particle Animator component, starting with color.
Local rotations allow you to create orbital effects for particles by revolving them around a given global or local axis.
In this video we take a look at the Size Grow property, which you can set to cause a particle to grow over time.
Particle forces are impulses, or an amount of velocity that is imparted to each particle on every frame. Good for effects such as wind and gravity.
Damping provides a global resistive force that will allow you to control what percentage of overall motion is conseved between frames.
The Autodestruct property provides you with an easy way to delete a particle emitter once all of its particles have been emitted and died out.
The Particle Renderer is responsible for the visual aspect of your particles. In this video we cover the Materials property of the component.
With the Particle Orientation setting, you can control which direction the particles will face throughout their lifetimes, to create a variety of different effects.
If you need the texture on a particle to change over time, you need to create a grid of picture textures, which are cycles using the UV Animation settings.
The World Particle Collider is the physics-based component of a particle system, allowing the particles to collide and interact with objects in the scene.
In this video we begin work on a simple demonstration particle system, being the effect of an arc welder.
We now continue on with our arc welding effect, creating the brilliant flash at the point of contact.
Our final touch for the arc welding system is to create the smoke that will rise off of the surface as it is being welded.
