Scratch blocks of code are needed to create a stopwatch
You will use some code blocks to build the script in Scratch:
Increase the variable (timer) by a specific number.
Reset the variable (timer) to 0 when starting the game.
Display timer variable to view the counter.
Take an action until something happens (time limit is reached).
An operation that checks if the first value (seconds passed) is equal to the second value (time limit).
About the clock timer script
Before creating variables and building scripts, it's important to understand how the timer script works. Study the scenario below:
Is the value of the timer 15? If not, wait a second, then increase the timer to 1 second. Repeat until the timer is equal to 15.
Watch the video below to understand how the timer can be used to set game time limits. If this is the programming project you want to do, read on for instructions on building game scripts with the goal of earning points while playing many other interesting Scratch tips.
How to create stopwatch in Scratch
Create timer variables
1. Open the game project saved in Scratch.
2. Select the sprite used to track time (can be a player).
3. From the Variable panel, click Make a Variable .
4. Type Timer as the variable name. Click Ok .
5. Select the timer variable to display it.
6. Use your skills to build the scenario:
Here is an example:
Tips for setting up the formula code block:
See the Operator table.
Drag __ = 50 into the if-then block .
Edit the number of seconds on the time limit. For example, 15.
See the Variable table . Add a Timer .
Check the timer
7. Play the game. When done, click Stop . Please answer the following two questions:
Does the timer increase as a second passes?
Does the timer stop when it reaches the time limit?
Set the time to 0 when the game starts
8. Play the game again. Do stopwatches start from 0? If not, do the following:
9. Select the time tracking sprite.
10. From the Variable table, add set my variable to 0 to start the script. Click the variable arrow and select the timer .
11. Play the game again. The timer will start from 0.
Above is how to create a stopwatch for the game when programming with Scratch. Hope the article is helpful to you.
