📚 Topic Summary
Moving sprites is all about making the characters or objects in your computer programs, especially games, change their position on the screen. This is done by changing their x (horizontal) and y (vertical) coordinates. Think of it like a map where each sprite has an address. By changing that address repeatedly, we create the illusion of movement. We can also control how fast they move and in what direction!
Worksheets like this help practice coding concepts related to sprite movement, like using loops to make movement continuous, using conditional statements to change direction when hitting an edge, or using variables to control the speed of the sprite. It's all about problem-solving and creative expression!
🔤 Part A: Vocabulary

| 2. Coordinate |
B. A small image or object that can be moved on the screen. |
| 3. X-axis |
C. The horizontal line on a graph or screen. |
| 4. Y-axis |
D. The vertical line on a graph or screen. |

E. A location on the screen defined by numbers. |
✍️ Part B: Fill in the Blanks
Fill in the missing words from the following paragraph:
To make a sprite move, you need to change its __________. The __________ axis controls the horizontal position, and the __________ axis controls the vertical position. By changing these values repeatedly, the sprite appears to __________. We can use code blocks like 'change x by' and 'change y by' to control the __________ of the sprite.
🤔 Part C: Critical Thinking
Imagine you are creating a game where a cat sprite needs to chase a mouse sprite. Describe how you would use x and y coordinates and programming concepts to make the cat sprite follow the mouse sprite around the screen. What code would you use?
