Unity3d tutorial notes - unity initial 04

Here is finishing unity The fourth day of tutorial notes ！ Another day full of harvest ！！！

（ I did an example yesterday , Tomorrow is also expected to be an example ！）

One sentence per day ： Hide the knife into the sheath , It's gentleness , Also for the moment of swing , Cold knife light

GI

Global Illumination,GI Global illumination

Can calculate Direct light 、 Indirect light 、 The ambient light as well as Reflected light Lighting system , adopt GI The algorithm can make the rendered lighting effect more realistic and rich

Direct light ：

Light emitted directly from a light source , adopt Light Components Realization

Type type ：

The current type of light object

——Directional Light Parallel light ： Emit light in parallel , It can illuminate all objects in the scene , be used for Simulate the sun

——Point Light Point source ： Emitting light around the light position can illuminate all objects within its range , be used for Analog bulb

——Spot Light Spotlights ： Emit light to the conical area at the light position , As for the objects in this area will be exposed to light , be used for Analog searchlight

——Area Light Area light ： Emit light from one face in one direction （ Form a face , Go to Z Axis emission ）, Only irradiate objects in this area , Valid only when baking , Used in areas where light is concentrated .

Light that can only be used for scene baking , There is no real-time illumination , Because this light is extremely performance consuming

Hierachy（ Right click —>light—>Area Light）

 

attribute ：

Range Range ： The range of light emitted from the center of an object , Only applicable to point lights and spotlights

Spot Angle Spotlight angle , Only for spotlights

Color： The color of the light

Intensity Strength ： The brightness of the light

Culling Mask Choose a cover ： Select the layer to irradiate Layer

Shadow Type Shadow type ：Hard Hard shadow 、Soft Soft shadows

——Strength hardness ： The degree of detail of the shadow

——Resolution The resolution of the ： Set the detail level of the shadow

——Bias The offset ： The offset of the object from the shadow

adopt Mesh Renderer Component enables or disables shadows

——Cast/Receive Shadows： Whether the current object is projected / Accept the shadow

There are many times when shadows need to be generated , But individual objects do not need to produce shadows , What do I do ？

—— All objects produce shadows , Look for light

—— Individual does not produce shadows , Find objects

object —>Mesh Rederer—>Lighting—>Cast/Receive Shadows

 

——Off Do not cast shadows 、On cast Shadows 、Two Sided sided shadows 、Shadows Only Hidden objects , Cast shadows only

—— Shadow culling ： Set the distance to display shadows

Ambient light ;

The illumination that acts on all objects in the scene , adopt Environment Lighting in Ambient control

Ambient Source Environment light

——Skybox Set ambient lighting by skybox color

——Graduent Gradient color

Sky Sky Color 、Equator Horizon color 、Ground Ground color

 

Ambient Intensity Ambient light intensity

Ambient Mode

——Realtime Real time updates , The ambient light will change. Select this

——Backed Bake , The ambient light will not change. Select this item

Reflected light

Calculate the reflection effect acting on all objects according to the sky box or cube map , adopt Environment Lighting in Reflection  control

Reflection Source

——Skybox Sky box

Resolution The resolution of the 、Compression Is it compressed?

——Custom Customize

Cubemap Cube map

Reflection Intensity Reflection intensity

Reflection Bounces Use Reflection Probe After that, the number of bounce back and forth between game objects is not allowed .

 

（ Ambient light ）（ Reflected light ）

Indirect illumination

The light reflected from the surface of an object after receiving light

adopt Light In the component Indirect Multiplier Rebound strength control

Be careful ： Only the mark static—>Contribute GI The object , To produce indirect rebound light

( Mark the stationary objects in the scene as static )

real time GI

Realtime GI

“ real time ” It refers to any modification of the light source during operation , And all changes can be updated immediately    

step ：

1. The game object is set to static

 

1. start-up Lighting panel Realtime Global Illur
2. Click on Generate Lighting（ If you check the Auto Generate, The editor will Automatic detection Scene changes 、 Fix the lighting effect ）

 

Mobile games generally do not need real-time GI,PC Use it as a tree, and the shadow will follow                 

Bake GI   

Baked GI  

When the scene contains a large number of objects , Real time lighting and shadows , It has a great impact on game performance . Use baking techniques , Can be Light effect Pre shading and dyeing Mapping Again Act on an object to simulate light and shadow , To improve performance , Suitable for programs running on low performance equipment .           

The object is marked static —>Light—>Mode

 

Light Components Mode attribute ： Baking mode  

——Realtime Only real time works

——Baked Only works when baking

——Mixed blend , Baking and real-time lighting work             

Can pass Scence panel Baked View lightmaps in mode

Light source detection

Light Probes

because Light Maooing It only works on Static object , Therefore, the moving object cannot be fused with the light in the scene , It seems very unreal , and Light Probes Components can be accessed through Probe Collect light and shadow information , Then, several adjacent to the moving object Probe Perform interpolation , Finally, light is applied to the object .

step ：

1. Create objects Light Probe Group
2. Add detection ball Add Probe
3. Click on Generate Lighting（ If you check the Auto Generate, The editor will Automatic detection Scene changes 、 Fix the lighting effect ）  

voice ：

Unity Supported audio file formats

Mp3、ogg、wav、aif、mod、it、s3m、xm

The sound is divided into 2D、3D Two types of ：

3D voice ： There's a sense of space , Near and far away （ Like the sound of game script ）

2D voice ： Suitable for background music

 

Generate sound in the scene , It mainly depends on two components ：

Audio Listener Audio monitor ：

Accept the audio source in the scene Audio Source Sounds made , Play sound through the computer's speakers

Audio Source Audio source component

——Audio Clip audio clip ： Audio resources to be played

——Mute Mute

——Play On Awake Wake up play ： Automatically play when the scene starts

——Loop Play

——Volume The volume

——Pitch tone ： Change the tone value to adjust the audio playback speed .1 It's normal speed

——Stereo Pan：2D Sound set left and right channels

——Spatial Blend:2D And 3D Sound switching

3D Sound Settings

 

Volume Rolloft Attenuation mode of volume         

 

The larger the distance of this figure , The lower the volume ,x The axis represents the distance ,y The axis represents the volume , The curve is the volume attenuation curve

（ You can adjust the curve ）
