I am using this code on glsl script
but when i use if else condition it not works , every time i run script it choose the first value of color variable which is declared before if else condition.
float color = 0.3 * clr.r + 0.59 * clr.g + 0.11 * clr.b; // script always choose this value instead of if else values
float maxrgb = max(max(clr.r, clr.g), clr.b);
if (maxrgb < 128.0) {
float color = 0.21 * clr.r + 0.71 * clr.g + 0.80 * clr.b;
} else if (maxrgb > 128.0) {
float color = 0.30 * clr.r + 0.60 * clr.g + 0.82 * clr.b;
} // the values in the condition are not working.
is am i doing something wrong ?
You have declared the color variable twice. You have declared a new variable with the same name in scope of the if-statement. Declare the variable before the if statement, but assign new values to the existing variable in the statement:
float color = 0.3 * clr.r + 0.59 * clr.g + 0.11 * clr.b;
float maxrgb = max(max(clr.r, clr.g), clr.b);
if (maxrgb < 128.0) {
color = 0.21 * clr.r + 0.71 * clr.g + 0.80 * clr.b;
} else if (maxrgb > 128.0) {
color = 0.30 * clr.r + 0.60 * clr.g + 0.82 * clr.b;
}
