语法错误，意外＆＃39; {＆＃39;在令牌＆＃34; {＆＃34;

Question

所以在这堆代码的某处我得到了上面的错误（如标题所示），我花了很多时间试图找出原因。

vec4 calcPointLight(PointLight pointLight, vec3 normal);
 {
  vec3 lightDirection = worldPos0 - pointLight.position;
  float distanceToPoint = length(lightDirection);
  lightDirection = normalize(lightDirection);

  vec4 color = calcLight(pointLight.base, lightDirection, normal);

  float attenuation = pointLight.atten.constant +
                      pointLight.atten.linear * distanceToPoint +
                      pointLight.atten.exponent * distanceToPoint *  distanceToPoint +
                      0.0001;

返回颜色/衰减;

Answer 1

摆脱第一行末尾的分号。

附注：你应该真正提到你至少使用的语言。
