I’m trying to solve an exercise, that i have to do a line, with for cycle. I need that it looks like this

6  
8  
9  
3  
1

but the only thing that I have is multiple numbers, in the same place, multiple times. I don’t know how to pick different random numbers every time the cycle for runs only once, and not every time the void draw read the code. I understand that the random function it’s inside the void draw, but, if I put it into the void setup, it only choose all the times the same number, like this:

2  
2  
2  
2  
2

the code that I am using, is this, hope someone can help me and fix it ❤

int tam = 25;  
int valAnterior;

void setup(){  
size(600,400);  
textSize(tam);

}

void draw(){  
background(200);  
for(int i=1; i\<6; i++){  
text(valAnterior, width/5, i\*tam);  
valAnterior = round(random(0,9));  
}

}

Hello,

Look up each function you are using (and the related ones) and a solution will be forthcoming.

One of the best tools in a programmer’s tool chest is knowing the resources available to you and learning to navigate, filter, and use them.

A short list of resources to peruse:
