This function is used to check if the input image belongs to one of the classes previously defined. The class to be checked with can be set using the argument as label_number.
The example demonstrates how to make the sprite track and stamp its image on the mouse when the space key is pressed in Python.
Code
sprite = Sprite('Tobi')
pen = Pen()
pen.clear()
while True:
if (sprite.iskeypressed("space")):
sprite.setx(sprite.mousex())
sprite.sety(sprite.mousey())
pen.stamp()
