Depends on how you're making it move.  You really need to post your code if you want to get a helpful answer...

You could try the frameRate() command, but if slowing the sketch down makes it too jerky, then there are more sophisticated techniques as well. Try frameRate() first though, it's easy! =)

You probably need to do some % math, something like this?

Awesome! Thanks you guys! Especially to jack.kern and fietspomp! The frame rate coding worked perfectly in combination with the "random" code. I guess I can post the final code. xD
There is a random "float" in the beginning because it did not like it when I suddenly put in "random" into the movement equation. When I changed the variable type to "float", the program let the code produce what I was looking for.


int WIDTH=500,HEIGHT=500;   //window size

float xlocation, ylocation;

int numFrames = 10;  //number of frames for movement
int frame = 0;

void setup() {
  //basic window setup
  size(WIDTH,HEIGHT);
 
  //image will start from the center
  xlocation=213;
  ylocation=175;
 
  //frame rate
  frameRate(2);
 
}

void draw() {
  background(255);

//movement
xlocation=(random(0,WIDTH)) % (WIDTH-50);
ylocation=(random(0,HEIGHT)) % (HEIGHT-50);

//Body move
stroke(0);
fill(0,255,60,50);
rect(xlocation,ylocation,75,125);

//Hair move
stroke(0);
fill(249,228,33);
ellipse(xlocation+37,ylocation-75,200,125);

//Head move
stroke(0);
fill(249,212,176);
ellipse(xlocation+37,ylocation-25,100,100);

//Left Arm move
stroke(0);
line(xlocation,ylocation+25,xlocation-38,ylocation+60);
line(xlocation-38,ylocation+60,xlocation-88,ylocation+35);

//Right Arm move
stroke(0);
line(xlocation+75,ylocation+25,xlocation+107,ylocation+125);

//Left Leg move
stroke(0);
line(xlocation+7,ylocation+125,xlocation-38,ylocation+165);
line(xlocation-38,ylocation+165,xlocation+12,ylocation+210);

//Right Leg move
stroke(0);
line(xlocation+68,ylocation+125,xlocation+137,ylocation+210);

//Fire Ball move
stroke(249,96,0);
fill(249,96,0,180);
ellipse(xlocation-88,ylocation+15,50,50);

//Eyes move
stroke(0);
fill(255,0,0);
ellipse(xlocation+12,ylocation-35,20,20);
ellipse(xlocation+62,ylocation-35,20,20);

//Mouth
stroke(0);
fill(249,0,129);
rect(xlocation+27,ylocation-5,20,10);

}

This is exactly why I suggested you post your code.  Rather than relying on a kludge to fix the problem we can address it directly.

Try removing the frameRate() call and putting this into the draw loop:

int speed = 5;
//movement
xlocation += random(-speed,speed);
ylocation += random(-speed,speed);

Note that " += random(-speed,speed);" is equivalent to writing "xlocation = xlocation + random(-speed,speed);"

Now instead of setting a large random value and effectively generating a completely new location each frame you add a small positive or negative random value to the current position.  There are ways of smoothing this type of motion somewhat (e.g. noise() might be a better option than random()); or alternatively you can move at a fixed speed and reverse movement when you reach the edge of the screen.

I'd suggest you have a look at the Motion section in Learning > Topics
