1. Problems encountered
Question 1: The project requires scene rendering
I searched online for scene rendering, which should mean making the scene more natural by adding different materials and adjusting some lights.
Production and rendering of this unity scene seen at station B
Question 2: The SelectIcon of the scene is too small to see clearly
By adjusting this property
Question 3: When the project is running, it is found that other windows are missing, there is only one Game window and it is maximized, resulting in UI deformation
Because the Maximize On Play on the right is turned on, the display is maximized when it is turned on,
and it is best to choose the ratio of the resolution on the left at the beginning so that the scene UI can maintain the ratio and is not easy to deform
Question 4: Problems with initial attempts at network requests
Because I used an unreferenced class, I went to the official website
to download it according to the article. After downloading, I still reported an error. I found that there was no reference added.
After confirming the download, I deleted it and downloaded it again. I found that there was one in vs. Reference, but there is no reference in Unity, and an error is still reported.
Re-download the file with dll from the official website, put it into Unity again, and it succeeds later
// 定义回调函数 其实就是委托
delegate void SendRequestCallback(JObject returnData);

//两种写法

{
}
private void Start()
{
//SendRequestCallback sendRequestCallback = new SendRequestCallback(CallBack);
SendRequestCallback sendRequestCallback = delegate (JObject returnData)
{
JObject data = (JObject)returnData["data"];

useful knowledge points
1. Put the generated object into an object and set the parent node of the object
people.transform.parent = peopleParent.transform
2. Get time
DateTime time= DateTime.Now;
string strNowTime = string.Format("{0:D}-{1:D}-{2:D} {3:D}:{4:D}:{5:D}", time.Year, time.Month, time.Day, time.Hour, time.Minute, time.Second);
3. Display the playing video on the UI interface
[Unity] Display and play video on the UI interface
4. Use the version manager PlasticSCM that comes with Unity
About the initial use of Unity's version control tool PlasticSCM
5. Use code to change the Lighting property of the scene
//改变场景中的天空盒
RenderSettings.skybox = skyBox;
//改变场景中的lntensity Multiplier （强度乘数）
RenderSettings.reflectionIntensity = 0.5f*(index+1);
//RenderSettings.ambientMode = UnityEngine.Rendering.AmbientMode.Flat;
RenderSettings.ambientSkyColor = index == 0 ? Color.HSVToRGB(0, 0, 0.2078f) : Color.HSVToRGB(0, 0, 0.9608f);
6. Right-click the Properties of the object in the Hierarchy window to open the locked Inspector window of the object
7. DOTween is a very powerful tween animation plug-in
You can easily realize some animation effects, you don’t need to write the animation controller yourself, you can also realize some camera movement, UI animation, etc.
Details: DOTween Chinese detailed explanation (continuously updated)
easing curve: Dotween SetEase Ease easing function
8. UniStorm is a very useful weather system plug-in
The weather system UniStorm of the Unity plug-
in uses the UniStorm plug-in to dynamically modify the weather effect according to the current city
Some summary of shallow use:
1. When creating, you need to use an object called Player whose tag name is also Player to store the prefab, and the particle effects of rain and snow weather can only be seen near it. 2. The
control panel is a Canvas prefab and UI public should adjust the priority, otherwise it will be overwritten
3. The options of the control panel are in
4. The weather type is obtained through the subscript of the built-in weather comparison table
