Question by fireArchMage23 · Nov 24, 2015 at 08:15 PM · shader array error message for-loop out of bounds

What is the problem with the loop?

I am programming a shader and I am getting an array index out of bounds error. The error is at :

     LightInfo lt;
 IlluminationResult illumTotal;
 int lighttemp = lights.Length;
 for (int i = 0 ; i < lighttemp; i++) {
     // Get the light informatio from i:th light
     lt.P = lights[i].get_position(mtl); // error line**
     lt.D = lights[i].get_direction(mtl); 
      ....
     }

I have followed the code back and I can't find an error.

may you check Debug.Log(lights.Length);

it says that there is an undeclared identifier when I add the debug statement.

did not see definition of light[], probably, I guess you do not define like

 Light[] light = new Light[10];

@say_forever lights[] is defined as: FXComposerPointLight lights[1];
