Particle Animators move your particles over fourth dimension, you apply them to employ wind, elevate & color cycling to your particle systems.
Properties
| Property: | Function: |
|---|---|
| Does Animate Color | If enabled, particles bike their color over their lifetime. |
| Color Animation | The 5 colors particles go through. All particles cycle over this - if some have a shorter life span than others, they will breathing faster. |
| World Rotation Axis | An optional world-infinite centrality the particles rotate around. Utilize this to brand avant-garde spell effects or give caustic bubbling some life. |
| Local Rotation Axis | An optional local-infinite axis the particles rotate around. Utilize this to make advanced spell effects or requite caustic bubbling some life. |
| Size Grow | Use this to make particles grow in size over their lifetime. As randomized forces volition spread your particles out, information technology is often overnice to make them grow in size so they don't fall autonomously. Employ this to make smoke rise upwards, to simulate current of air, etc. |
| Rnd Forcefulness | A random force added to particles every frame. Utilise this to make smoke become more than alive. |
| Force | The forcefulness being applied every frame to the particles, measure relative to the world. |
| Damping | How much particles are slowed every frame. A value of i gives no damping, while less makes them slow down. |
| Autodestruct | If enabled, the GameObject attached to the Particle Animator will exist destroyed when all particles disappear. |
Details
Particle Animators permit your particle systems to be dynamic. They let you to alter the color of your particles, apply forces and rotation, and choose to destroy them when they are finished emitting. For more data about Particle Systems, reference Mesh Particle Emitters, Ellipsoid Particle Emitters, and Particle Renderers.
Animative Color
If you would like your particles to change colors or fade in/out, enable them to Breathing Colour and specify the colors for the bicycle. Any particle organization that animates color will cycle through the 5 colors you choose. The speed at which they cycle will be adamant by the Emitter's Free energy value.
If you desire your particles to fade in rather than instantly appear, set your get-go or final color to accept a depression Alpha value.
Rotation Axes
Setting values in either the Local or World Rotation Axes will cause all spawned particles to rotate around the indicated axis (with the Transform'southward position as the centre). The greater the value is entered on one of these axes, the faster the rotation will be.
Setting values in the Local Axes volition crusade the rotating particles to adjust their rotation as the Transform's rotation changes, to friction match its local axes.
Setting values in the World Axes volition cause the particles' rotation to be consequent, regardless of the Transform's rotation.
Forces & Damping
You lot use strength to make particles accelerate in the direction specified by the strength.
Damping can be used to decelerate or accelerate without changing their direction:
- A value of 1 means no Damping is applied, the particles will not slow downward or advance.
- A value of 0 means particles will finish immediately.
- A value of 2 means particles volition double their speed every 2d.
Destroying GameObjects attached to Particles
You can destroy the Particle System and whatever fastened GameObject by enabling the AutoDestruct property. For case, if you accept an oil drum, you tin can attach a Particle System that has Emit disabled and AutoDestruct enabled. On collision, you lot enable the Particle Emitter. The explosion volition occur and later it is over, the Particle System and the oil pulsate will exist destroyed and removed from the scene.
Notation that automatic destruction takes effect only after some particles have been emitted. The precise rules for when the object is destroyed when AutoDestruct is on:
- If in that location take been some particles emitted already, but all of them are dead at present, or
- If the emitter did have Emit on at some point, but now Emit is off.
Hints
- Use the Color Animation to brand your particles fade in & out over their lifetime - otherwise, you lot will get nasty-looking pops.
- Apply the Rotation Axes to brand whirlpool-like swirly motions.
