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.

How to Make Countdown a Maze Game on Scratch



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



How to Make Countdown a Maze Game



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 pressed. For this, we add the "If" code from the "Control" menu. If it is inside, we can check which button is pressed or not from the "Sensing" menu. We start checking whether the "Up Arrow" button is pressed or not. If the up arrow key is pressed, our object will move in the positive direction in the Y coordinate. In this coordinate, we can increase Y by 3 and make it go 3 steps. We check in the same way whether the down arrow key is pressed or not. This goes in the negative direction in the Y coordinate. Then we can increase Y by -3 so that the object goes down. When we press the Right arrow key, it moves in the positive direction in the X coordinate, and when we press the Left arrow key, it moves in the negative direction in the X coordinate. If we want the game to end when the object touches the black lines, from the "Control" menu, if we use the code inside, from the "Sensing" menu, "Is it worth its color? We use the “ code and make the color black. If it hits the black lines, we use the "Hello de" code from the "Looks" menu and change it to "Sorry you lost". In the next code, we give the starting point of the object and make the object go there automatically. We always stop the increasing time with the stop all code from the "Control" menu. We also prevent the object from moving. If the object has reached the end point or not, we get the code from the "Control" menu, and if it touches the green color from the "Sensing" menu, we remove the text " Congratulations You Won". And we add “Stop all” code to stop the time. We check if our time is over with the "If" code. We get the time variable in the variables menu. We put the time variable inside the two expression equals code in the operation section. In the other part, we write 0. Thus, if the duration variable is equal to 0, the message "Sorry your time is up" appears.

In order to make the time countdown, we wait 1 second in the repeat code and decrease the duration variable by 1. Thus, the duration variable decreases by 1.

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...
