sf::Shader uniform array

[bmn]

How do I send data to uniform array with sf::Shader ? I've tried using this:

float v3Colours[30];
for( int i = 0; i < 10; i++ ){
        v3Colours[ i * 3    ] = i*0.1;
        v3Colours[ i * 3 + 1] = 1.0-i*0.1;
        v3Colours[ i * 3 + 2] = 1.0-i*0.1;
}
glUniform3fv(glGetUniformLocation(id, "v3Colours"), 10, v3Colours);

but I don't know program id. Is it even possible ?

Is it even possible ?

Nop.

But you mean its not possible in sfml or in glsl itself. This is how I got code above

This is not possible with SFML, but if you had the program ID (which is not possible with SFML) you could make your code work.

Oh ok, thanks. New feature in 2.x ?

sf::Shader will probably be improved, yes.
