In SNAP!, a reporter block is used to report a value, which is generally used as an input to another block. What do reporter blocks look like? Reporter blocks can be easily identified in the palette as they have reporter shape (round). For example, the following blocks in the Motion […]

Last week we covered an important computer science concept, Variables, and how to use them in a simple jump example. Variables gives us the ability to store a value and track/modify/use it throughout the program. Additionally, last month, we had covered the concept of functions. Functions are a great way […]

In my previous blog, we covered how you can customize your script to take user input and make your sprite jump to the height specified by user. Now let’s extend the previous scenario to asking user input for both height and length of the jump. How would you enhance your […]

In previous blogs, we have covered different aspects of coding practices using a simple Sprite Jump example. In this blog, I will build on top of the code we built in Good Coding Practice: Using Relative Coordinates. Here is what our Sprite Jump code looked like: Now let’s say we […]

Let’s say you create 3 sprites (of ball shapes – learn how to change the sprite’s costume): one of color Red, other of Blue and last one of Green. Now you want all three to jump when different keys are pressed. For example, Red one should jump when key ‘a’ […]

In the previous blog, we covered how to make the sprite jump, and this is what our script looked like: What will happen every time you click on green flag? The sprite will come to the center of the stage (coordinates [0,0]) and then glide to [20,20] coordinates and then […]
