Hello, I’m currently learning how to use processing in the school for an upcoming big project- making an advertisement for sports day. For my advert, I want to make my stickman running by animating the stickmans, but I don’t know how to. Can someone please tell/help me how to animate stickmans to make them run?

first you need to have someone or you draw the stickman then flip through the pictures

That’s right.

It’s very hard to do programmatically, especially the coordination of the angles

see also [Push matrix and trig functions help (robot BD-1)](https://discourse.processing.org/t/push-matrix-and-trig-functions-help-robot-bd-1/16795)

example below with one leg

```auto
float x; 

float a=2.29;
float aAdd=.04; 

float b=0.3;
float bAdd=.04; 

void setup()
{
  // init
  size(1800, 600);
} // func 

void draw() 
{
  // runs on and on 
  background(0);

  stroke(255); 

  translate(width+x, height/2); 
  x--;
  ellipse(-6, -66, 22, 22); 
  line ( 0, -44, 
    0, 44);

  // upper thigh
  translate(0, 44);
  rotate(a);
  line(0, 0, 44, 0);

  // lower thigh
  translate(44, 0);
  rotate(b);
  line(0, 0, 44, 0);

  a+=aAdd;
  if (a>2.5)
    aAdd=-1*abs(aAdd);
  if (a<.6)
    aAdd=abs(aAdd);

  b+=bAdd;
  if (b>0.0)
    bAdd=-1*abs(bAdd);
  if (b<-1)
    bAdd*=-1;
} // func 

// --------------------------------------------------
