Now let's put it all together! In this activity, we will use Python code to animate Tobi walking across the Stage by switching between costumes and moving him step by step.

Setting Up

Open PictoBlox and create a New File.
Select Python as the coding environment.
Make sure Tobi is on the Stage and has at least two walking costumes (Tobi Walking 1 and Tobi Walking 2).
Set a backdrop of your choice — the Forest backdrop works great!

How the Animation Works

An animation is created by rapidly switching between costumes while moving the sprite. We will use a loop to repeat the costume switch and movement many times, creating the illusion that Tobi is walking.

Writing the Script

Type the following Python code in the editor:

import time # Set starting position tobi.go_to(-180, -80) tobi.point_in_direction(90) tobi.set_size(60) # Walking animation loop for i in range(30): tobi.switch_costume("Tobi Walking 1") tobi.move(8) time.sleep(0.1) tobi.switch_costume("Tobi Walking 2") tobi.move(8) time.sleep(0.1)

Understanding the Code

Code Breakdown

Line	What it Does
import time	Imports the time module so we can use time.sleep()
tobi.go_to(-180, -80)	Positions Tobi at the left side of the Stage
tobi.point_in_direction(90)	Makes Tobi face right
tobi.set_size(60)	Sets Tobi's size to 60%
for i in range(30)	Repeats the loop 30 times
tobi.switch_costume("Tobi Walking 1")	Switches to the first walking costume
tobi.move(8)	Moves Tobi 8 steps forward
time.sleep(0.1)	Waits 0.1 seconds before the next step

Running the Script

Click the Run button to execute the code.
Watch Tobi walk smoothly across the Stage!
Try changing the range(30) value to make Tobi walk further or shorter.
Try changing time.sleep(0.1) to make the animation faster or slower.
