loop()

Resumes the draw loop after noLoop() has been called.

By default, draw() tries to run 60 times per second. Calling noLoop() stops draw() from repeating. The draw loop can be restarted by calling loop().

The isLooping() function can be used to check whether a sketch is looping, as in isLooping() == true.

Examples

loop example 1

function setup() 
  size(100, 100)

  -- Turn off the draw loop.
  noLoop()

  windowTitle('Loop example')
  describe(
    'A white circle starts moving to the right when the user clicks.'
  )
end

function draw() 
  background(200)

  -- Calculate the circle's x-coordinate.
  local x = frameCount

  -- Draw the circle.
  circle(x, 50, 20)
end

-- Resume the draw loop when the user clicks.
function mousePressed() 
  loop()
end
