Unity3d learning notes (I)

Hello everyone , I meet you again , I'm the king of the whole stack , I wish every programmer can learn more languages .

operation ： Press down shit Click on the center of the axis Switch perspective

The concept of animation baking ： Equivalent to the original controller animation or IK（ bones ） Animation all collapses into frame by frame animation , You must select this item when exporting

Shaders ： From a technical point of view , The shader is Renderers Part of , It is responsible for calculating the color of the target

shader、texture As material Part of , Usually used together

shader:

diffuse Dispersion 、 Scatter the single channel color model

bumped diffuse Concave convex spread two channel model 、 Set more normal maps than above

bumped specular The effect of concave convex specular highlights ..

Normal map ： Distinguished from 2d Plane mapping , Can be understood as special “ Bump map ”

Normal mapping can be applied to 3D Special texture of surface , Unlike previous textures, they can only be used 2D The surface of the . As an extension of bump texture , It contains the height value of each pixel , Surface information with many details , Can be on ordinary objects , Create many special three-dimensional shapes . You can imagine the normal map as a point perpendicular to the original surface , There is a different surface for all the points . For visual effects , Its efficiency is higher than the original surface , If a light source is applied at a particular position , It can generate accurate light direction and reflection

Dynamic loading Resources( The premise must be Assets There is Resources Folder ) :

        private Texture2D imgTexture;
	private Texture2D[] imgs;

	void OnGUI()
	{
           if (GUI.Button(new Rect(10,50,50,50), "fuck One"))
		{
			Debug.Log("Clicked the button with an image");
			//Resources.Load<Texture2D>("oneMateral");
			imgTexture = Resources.Load<Texture2D>("oneMateral/Grass");
		}

		if(GUI.Button(new Rect(10,100,50,50), "fuck all"))
		{
			imgs = Resources.LoadAll<Texture2D>("allMateral");
		}

Copy

               /// The reason why it is placed below is to ensure GUI Every frame goes on texture Repaint 
		if(imgTexture != null)
		{
			GUI.DrawTexture(new Rect(80,50,100,100),imgTexture,ScaleMode.StretchToFill);
		}

		if(imgs != null)
		{
			for(var i=0; i<imgs.Length; i++)
			{
				GUI.DrawTexture(new Rect(80+  i* 100 ,150,100,100),imgs[i],ScaleMode.StretchToFill,true,0);
			}
		}
