A "random" Color

[Rideg]

Hello I'm wondering if there's a way to spawn circles with this color: [1.0, random color, 0.0, 0.7].

Is there a way to declare just the (0), (2) and (3) parts and let the (1) part be random?
EDIT-----------------------------------------
Without using any scene.my.* variables

You could try sin(scene.Time) for (1).

okey It'll work thank you.

Another way to do this :

Code: Select all

(e)=>{
    object = Scene.addCircle({
        radius := 0.05;
        pos := e.pos;
    });
    object.color = [1.0, object.color(1), 0.0, 0.7];
}

okey thanks I'll try that in a sec

Okey well instead of making a new thread I'll bump this one . Is there a way to limit REMqb's way so it the color will be random within specific parameters. Here's what I wrote:

Code: Select all

(e)=>{
    object = Scene.addCircle({
        radius := 0.05;
        pos := e.pos
    });
    object.color = [object.color(0), object.color(0), object.color(0), 1.0]
}

- A raondom grayscale object. Could I make like a "color limiter" so it wont reach almost white or black and be random between object.color = 0.3 and 0.5?

Sorry for the bump.

replace object.color(0) by (object.color(0)*(max-min)+min)

you will get :

Code: Select all

(e)=>{
    object = Scene.addCircle({
        radius := 0.05;
        pos := e.pos
    });
    grey = (object.color(0) * (0.5 - 0.3) + 0.3);
    object.color = [grey, grey, grey, 1.0]
}

I think now (in 1.7.4) you can use Palette so just set it do desire value in script.

but it only allows for HSVA limiting, instead of RGBA.

Okey thanks I'll try it tomorrow
