Shader.SetGlobalVectorArray I have a problem

Shader.SetGlobalVectorArray("PointLightPos",PointLightPos);
float4 colro=PointLightPos;
if i>0, I can't get the right value

So, am I using the wrong syntax, or how should I use the values in this array?

 

I need help. Thank you

 

Use SetGlobalVector if PointLightPos isn't an array, otherwise you'll need to change the shader to float4 colro[8]; where 8 is the maximum size of the array passed to the shader, for example.

 

thank you very much for your help
statement：
float4 PointLightPos[2];
float4 _fAttenuationValue[2];
float4 PointLightColors[2];

The above values are in a include file

I want to get the parameters of a particular Light by passing in the index but only array[0] is correct array[0+n] is wrong
