Notes

Certainly! Here are the steps for making a simple wall collision in Scratch: 1. Add a sprite to your project. 2. Click on the "Scripts" tab and create a new script for your sprite. 3. Drag out the "forever" block and put it at the top of your script. 4. Drag out an "if" block from the "Control" category and put it inside the "forever" block. 5. Click on the blue dropdown arrow and select "sensing" from the menu. 6. Drag out the "touching colour" block and drop it inside the "if" block. 7. Click on the colour picker and select a colour for your wall (this can be any colour you like, but it must be different from the colour of your sprite). 8. Drag a "stop all" block and place it inside the "if" block. Your script should now look like this:  9. Now, you need to make your wall. You can do this by adding a sprite, selecting the "Costumes" tab, and drawing a rectangle or line on the sprite using the same colour you selected in step 7. 10. Position your wall where you want it on the stage. 11. Press the green flag to test your script. When your sprite collides with the wall, it will stop moving!
