Converting Length to Meters and Centimeters With Scratch Program

We will make an example of Converting the Entered Length Measure to Meters and Centimeters with Scratch.

For this sample application we made with the Scratch program, first of all, we create data from the variables menu to hold the data in meters and centimeters that will be created as a result of the process. Since I will create speech sprite in the program, I am adding a sprite.

Code part:

When the green flag is clicked, I first set 0 to the meter, centimeter and given length measurement. If we do not set 0, if the program has been used before, the numbers of the old data will appear in the first run. After writing the code that makes the data 0, we add the speech sprite that appear in the sprite from the looks menu. And we use the ask and wait command from the sensing menu to get the user's length measurement. After taking the length measurement in centimeters from the user, he came to convert it to meters and centimeters with mathematical operations and commands. The length unit entered in detection is kept in the response in the sensing menu. We equate these numbers retained in this entered response to the "Given Length" data we created earlier. Thus, we see the length measure entered by the person on the screen. To convert this length measure to meters, we follow the method below. We use the roll down command from the operator menu. We add the division command from the same menu to the space part. We enter the answer (variable holding the length measure entered by this user) divided by 100 from the detection menu of the empty part of the division command on the left. We add them to the meter variable. Thus, when the entered measure is divided by 100, we round the quotient and assign it to the meter variable.

In centimeters; When we subtract the result from the answer (the variable that holds the length measure entered by this user) by multiplying the meter with 100, the result is centimeters. For this, we use the remove operation command from the Process menu. We add the answer to the left space and the multiplication command to the right space. We write the meter variable in the multiplication command and 100 manually in the other. We put these codes into the centimeter variable. Thus, we convert the entered length measurement to meters and centimeters.

Pacman Game on Scratch Program

We will make an example of pacman game making with Scratch. Before starting the Pacman Game example that we will do with Scratch, we download the background for the pacman game from the internet and add it to the backdrop part in Scratch. When the background I downloaded was dark, I painted the dark colors with white. I made the borders thicker. After adding our background to our work, it came to creating the pacman character. I drew a full circle in yellow for the Pacman character. After that, I drew two lines towards the center using the line tool. I erased the remaining part with an eraser. If you want, you can use the erase background tool to erase between two black lines. Thus, our pacman character took his place with his mouth open. I created a guide dot right in front of the pacman character. This will keep us moving. I created a red dot. It's a little obvious, you can make this red dot smaller if you want, you can give it another color and make it more invisible. After cre...

How To Make Bubble Shooter Game on Scratch Program

We will make a bubble shooter game example with Scratch. I am adding 3 balloons and a target picture for the bubble shooter game we will make with Scratch. (You can increase the number of balloons). Now I come to the codes to be written inside balloon1. Let the number of balloons popped when the green flag is clicked is 0. Thus, the remaining numbers from the previous game are reset. Let the balloons be hidden at first. Then, it will appear in a random place between the coordinates we have determined at a random time between 1-5 seconds, wait for 2 seconds, then hide. X: The coordinates between -218/144 are the coordinates of the far left and the right of the screen, Y:134/-235 are the coordinates of the top and bottom of the screen. It will appear randomly in these ranges If our balloon is aimed and hit by the target; Balloon shot news is released. When this news reaches our balloon, the balloon will be hidden. Copy and paste the same code above. Then we say duplicate...

How to Make Countdown a Maze Game on Scratch

We will make a countdown maze game example with Scratch. For the countdown maze game example we will make with Scratch, we upload the maze picture we downloaded to our computer from the scene section to the scratch program. Then we select the object that we will move in the maze section from the choose a sprite section and add it to our scene. We bring the object to be moved to the red point, which is the starting point. First of all, we create a variable named Duration to calculate the elapsed time in the maze from the "Variables" menu When you click the green flag, set the duration variable to 40. Our goal is to get the ball to the finish line in 40 seconds. If our ball object to move, we give the x and y coordinates to go to the red starting point. Our object will not move only once. First of all, we add the "Forever" code from the "Control" menu so that it moves every time we press the arrow key. Now it's time to check which direction key is pres...
