Code:

class MyThing{
    int myNum = 3;
    float myVal = 4;
}
MyThing c;
void setup(){
    c = new MyThing();
}
void draw(){
    //Now, I can draw the mything:
    point(c.myNum,c.myVal); //Or something weird.
}
 

Your question is vague.

What I have outlined above is a very simple example of how to use objects. First define your own class, or use an existing one (like "String"). Then, "make" one with the keyword "new". You draw things in draw(), but you can specify what to draw! Just because you made an object doesn't mean it draws on its own. you have to make it draw! (the "point" call above draws a point according to c's values)

Hope this help.s
