Feature Request: Multiple Coloured Particles

[vandan-revanur]

I am trying to implement multiple coloured particles, however I am not able to add them into the same picture.

For example, I created a drawParticle_2 function:

drawParticle_2 :: Particle -> GG.Picture
drawParticle_2 (Particle _ (V2 x y) _) =
  GG.translate x' y' ( color (GG.circleSolid ( toPixels dotSize)))
  where
    x' = toPixels x
    y' = toPixels y
    color = GG.Color (GG.withAlpha 0.8 GG.green)

But I am not able to understand how I can add these green particles into the picture along with the existing blue particles.

Could you perhaps add a feature to add multiple coloured spheres ?

Hi there!

What a great idea making it more colorful! I would suggest that you extend the Particle type, so that there is a entry for its Color. Then you would (mostly) only need to change the intial model for each simulations by giving each particle a Color.

By adding the function drawParticle_2 you would have to distinguish between this function and drawParticle which becomes quiet hard in the current setup.

I hope this helps.

I created the branch feature/multiple_colors so that you can have a look, how I would have solved the problem. These changes will not be merged into main (same as for #8).

Feel free to ask further question. If there are none, I would like to close the issue.
