Question

所以我有这个着色器，我试图使闪烁，所以我使发射值在0和1之间来回，但它只有在我点击材料或在编辑器中滚动时才有效。我想不出来，请帮忙吗？

我检查了类似的东西，但它仍然无效，所以请帮助。

Renderer renderer;
Material material;
float emission;

// Use this for initialization
void Start () {
    renderer = GetComponent<Renderer>();
    material = renderer.material;
}

// Update is called once per frame
void Update () {

    emission = Mathf.PingPong (Time.time, 1f);
    Color color = Color.red;

    Color finalColor = color * Mathf.LinearToGammaSpace (emission);
    material.SetColor ("_EmissionColor", finalColor);

}

我解决了像你这样的问题请求分享您的着色器谢谢

尝试Mathf.sin（Time.time）来获得pingpong可能是你的问题解决了

或使用blow shader

Shader "Custom/Emition" {
    Properties {
        _MainTex ("Albedo (RGB)", 2D) = "white" {}
        _EmissionColor ("Bright", Float) = 1.0
    }
    SubShader {
        Tags { "RenderType"="Opaque" }
        LOD 200
        pass {
        CGPROGRAM

        #pragma vertex vert            
        #pragma fragment frag

        #include "UnityCG.cginc"


        uniform float _EmissionColor;
        sampler2D _MainTex;
        struct vertexInput {
            float4 vertex : POSITION;          
            float2 texcoord  : TEXCOORD0;
        };

        struct vertexOutput {
            float4 pos : SV_POSITION;
            float2 uv  : TEXCOORD0;
        };


        vertexOutput vert(vertexInput input)
        {
            vertexOutput output;
            output.pos = mul(UNITY_MATRIX_MVP,  input.vertex);

            output.uv = input.texcoord;
            return output;
        }

        float4 frag(vertexOutput input) : COLOR
        {   
            fixed4 c = tex2D (_MainTex , input.uv) ;



            /// change blow line 


            return c* float4(_EmissionColor,1,1,1);

        }
        ENDCG
    } 
    }
    FallBack "Diffuse"
}

更新着色器的发射时，它仅在我单击编辑器时更新[Unity]
