Aryan: What is this “reporter” block now? I have heard to this name for the first time in
scratch.

Gowri: Yes dear! These are the blocks, which are designed to fit in the input area of other
blocks and gives or returns the value of that variable or block.

Aryan: Ok dear, that’s interesting. Now, please tell me the script to calculate the score of the
game and code to decrease the life of the “spaceship” when “planet” hits the “spaceship”.

Gowri: Yes, let’s learn this with the activity given below:

Activity 6.5

Calculate the score in the game created above. Increase the value of the score

variable, when the sprite “missile” hits the sprite “planet” and also delete its
clone. Also set the life of the sprite “spaceship” as 5 and decrease its value,
when the sprite “planet” hits the sprite “spaceship”.

Answer

Step 1: Choose the sprite “planet” and create two variables named as “score” and
“life”.

Step 2: Two new reporter blocks named “score” and “life”
are also created with “variable” block (shown in
Fig. 6.7) and now set the value of the variable
“score” to 0 and variable “life” to 5 by dragging

“set… to…” block under “when flag clicked” block.
When this sprite hits the sprite “missile”, then
change the value of variable “score” by 1. Also
change the value of the variable “life” by -1 to Fig. 6.7

decrease its value, when this sprite hits the sprite “spaceship”. See
the coding for the sprite “planet” as shown in Fig. 6.8.
