What's the best way to implement a color cycling background?
What's the best way to cycle the color of a background smoothly (as well as other things) using cos or sin in java, without using more than one file? I've tried using randomness and increasing each individual r, g, and b value separately to make this look kind of normal, but it's jittery, not smooth, and the colors are horrid. Right now, it's just plain white. I included only the necessary code, and I am using Processing 3.
//background
int bg1 = 255; //r
int bg2 = 255; //g
int bg3 = 255; //b
void draw() {
fill(bg1,bg2,bg3);
}
You've got the general idea down. It's a three-step process:
- Step 1: Declare variables at the top of your sketch.
- Step 2: Use those variables to draw your scene.
- Step 3: Change those variables over time.
This is the basic approach to create any animation in Processing. Here is a tutorial with more information.
Here is a small example that shows a window that cycles between white and black:
float c = 0;
float cChange = 1;
void draw(){
background(c);
c += cChange;
if(c < 0 || c > 255){
cChange *= -1;
}
}
You would need to do something similar, but with 3 color values instead of 1. Note that I'm only changing the color by a small amount each time, which makes it appear smooth instead of jittery.
If you're still having trouble, please post an updated MCVE in a new question and we'll go from there. Good luck.
