Exponential increase of integers

in Programming Questions • 2 years ago

I am working on a car dashboard simulator, I have it working alright, but it is not realistic as the tachometer is a steady speed all the way from 0-100k rpms, is there any way to have it start slow but then slowly pick up speed, same thing with the speedometer as you change gears with the arrow keys

if you want to post some code use the Code Tag and not the Quote Tag, that makes it harder to copy and paste your text

Re: Exponential increase of integers

not really sure what you have in mind, but a simple way would by something like this

float x;
float y ;
void setup(){
size(700,700);
x = 0;
y = 1;
}
void draw(){
ellipse(x,height-y,4,4);
x+=1;
y= y*1.01;
}
