Problem with changing the color of a custom shape (line) in P3D

in Programming Questions • 5 months ago

At the moment, I am attempting to change the color of a custom shape.

stroke(3);

fill(255, 0, 0);

beginShape();

vertex(x, y, z);

vertex(a, b, c);

endShape();

However, this doesn't change the line to red or change the stroke of the line at all. A black line is drawn instead. The code above is within a for loop within a pushMatrix() popMatrix() block, but the fill in that scope is not black and works as desired.

What would be causing the lack of color/stroke change and what is the solution?

Edit: Now that I look at it more, any stroke isn't changing the width in the program wider than what looks like 1 unit.

You see a black line, because your stroke is 3/255, meaning it is very subtle, and you wont see the change.

Let me clear this up: fill() is used to color faces, not edges, which is what a line is.
You must use stroke(), which you were using, to color the line.

Edited code below:

stroke(255, 0, 0); //This will give you bright red color.

fill(255, 0, 0); //This doesn't do anything at the moment, as you need at least 3 edges.

beginShape();

vertex(x, y, z);

vertex(a, b, c);

endShape();

Ah, ok. :-) That makes sense. Thank you!
