The function changes the specified sound effect to the value. The input is for selecting how much the sound will be changed. A positive number will make the sound effect have more effect, while a negative number will make it smaller.
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()
