How to change the color of Particle System?
I have a particle system for this ball rolling on the ground. I want the particles to change color every time the surface that it is rolling on changes color to correspond with the ground color.
You can look at the script reference for a Particle System and you can change the color using the Color reference page.
After the recent update this is done via:
ParticleSystem.MainModule settings = GetComponent<ParticleSystem>().main;
settings.startColor = new ParticleSystem.MinMaxGradient( yourColor );
You can also assign a Color to ParticleSystem.$$anonymous$$ain$$anonymous$$odule.startColor like:
settings.startColor = yourColor;
as explained in https://docs.unity3d.com/ScriptReference/ParticleSystem.$$anonymous$$ain$$anonymous$$odule-startColor.html
I am confused by the new particle system API. It seems like the color and size properties can no longer be manipulated for individual points/particles. How would I re-write myArray[i].color = new Color(x, 0f, 0f) or myArray[i].startSize = 0.1f or Color c = myArray[i].color; c.g = p.y; myArray[i].color = c for example?
This seems like a cumbersome way to just change a color. Couldn't they have just added some method or a simple way to do it, like how was done before?
emc233 is wrong and not even trying to help. it's through the startColor attribute of the Particle System
this.GetComponent<ParticleSystem>().startColor = new Color(1, 0, 1, .5f);
It actually used to be ParticleSystem.color but that was depreciated sometime ago as it is a procedural calculation so you should use ParticleSystem.startColor to get/set the start color or use ParticleSystem.GetCurrentColor(...) to get the current color
This is useful info if your wondering how you should go about updating depreciated code
