def keyPressed():

    global interpolateShortest

    if key=="1": 

        interpolateShortest=True

    elif key=="2": 

        interpolateShortest=False

```

question :when i pressed mouse i couldn’t make shakeColors() function work. How can i make it work ?

Welcome, @Mayarch

You’re listening for **key** , not **mouse** input. In other words, when the user presses the 1 or 2 key on the keyboard.

I assume that you want to detect left and right mouse clicks:

```auto
...

def mousePressed():
    global interpolateShortest
    
    if mouseButton == LEFT:
        interpolateShortest=True

    elif mouseButton == RIGHT: 
        interpolateShortest=False

```

def mousePressed():

```
if mouseButton==LEFT:

    shakeColors()

```

sorry i forgot that definition what i want.but i couldn t rework shakeColor function again when i pressed mouse left click

    elif key=="2": 

        interpolateShortest=False

def mousePressed():

    if mouseButton==LEFT:

        shakeColors()

```

i changed the name shakeColors as makeColors and then i redefined colorsLeft, colorsRight lists indexes again with shakeColors function. then solved
