Space Wars Game With Scratch Program

 

Space Wars Game With Scratch Program

Together with the Scratch program, we will make an example of Space Wars game. Shooting and hitting the rocks coming with the spaceship in the space wars game we will do with Scratch. Every time the rocks hit, a life is lost. For this, we first add a space picture to the background in Scratch. We draw 1 Spaceship, 3 Rocks, 1 Bullet from Sprite and add work. From the data, we create a data that we will use in all Sprites with the Number of Rocks Hit and the Health Remaining before the game starts.


Space Wars Game With Scratch Program

We select the Spaceship we added and write the above codes in it. First of all, we check which key the user presses or not, which key the user will press and play in the "If" code. If the up arrow key is pressed, we increase the y positive direction by 5 and make the ship move upwards. If the down arrow key is pressed, y takes 5 steps in the negative direction. So there is a downward movement. If the left arrow key is pressed, it moves to the left in the x negative direction. If the right arrow key is pressed, it moves to the right in the x positive direction. The purpose of putting the repeat code here is to keep our ship moving as long as the arrow keys are pressed. Otherwise, we would have to constantly pull our hands away and press the buttons. Haber 3 is the receive that was sent when the bullet hit the rock. When this receive comes, the Number of Rocks Hit increases by 1. In Haber 2, when the receive of the rocks hitting the spaceship comes, we reduce the Remaining Health by 1. If Remaining Health is equal to =0, we remove the warning message and stop the whole game.


Game Making with Scratch

We select the rock we added first and add the above codes into the rock. Let the Number of Rocks Hit from the beginning of the game be 0. If the remaining life is 5. After 0.5 seconds, our Rock will go to a random place in the x and y coordinate range specified in the codes. (We make the rocks hidden before the game starts). However, we have to do some checks here. Did a bullet hit the rock? Was the Rock Aside? or Rock or Was the remote ship worth it?

Possibility 1: Did the bullet hit Rock? If it is worth it, our rock will disappear, that is, it will be hidden. It will wait 0.5 seconds and our rock will appear in a random place in the x and y coordinate range we have given. and it will release Haber 3 receive. With the arrival of this news, the Number of Rocks Hit will increase by 1.

Possibility 2: Did our rock touch the lower edge of the screen? If it is worth it, our rock will disappear, that is, it will be hidden. It will wait 0.5 seconds and our rock will appear in a random place in the x and y coordinate range we have given.

3. Possibility: Did the rock touch the spaceship? If it is worth it, our rock will disappear, that is, it will be hidden. It will wait 0.5 seconds and our rock will appear in a random place in the x and y coordinate range we have given. And it will release Haber 2 receive. With the arrival of this receive, our remaining life will decrease by 1.

 So our Rock will move and become the target of the bullet or spaceship. By right-clicking on the rock and saying copy it, we duplicate our rock and the codes in it. If all we have to do is change the x and y coordinates where the rock will appear, we will have too many rocks in a row.


Scratch games

The codes we will write inside the sprite are as above. Our bullet is initially above the ship. However, with the ascend code we wrote inside the ship, the spaceship rises above the bullet and the bullet becomes invisible. To move the bullet with the spaceship. Until the spacebar is pressed, the x position and y position of the bullet are the x and y positions of the spaceship and we say go to those points. Thus, wherever the ship goes, the bullet goes with it. When the spacebar is pressed, the bullet should come out of the ship. When this key is pressed, the bullet release news is released. and moves in the y direction.

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...

Apple Picking Game with Potentiometer- Mblock with Arduino

 Before moving on to this application, we had done the LEDLighting with the Potentiometer. You can learn the installation of the potentiometer and the necessary materials here.   Let's write our codes in the Mblock program. First of all, find a background from the internet, we change the background from the scene section. I add 3 apples (you can increase the number of apples) and 1 basket from the new puppet part.   Here are the codes in Apples: Since the green flag is clicked, we add the code to get our variable number of apples 0, which we created from the data section. If we do not add this, the number of apples collected will continue from where it left off if the game was played before. We take the code that generates random numbers from the operations menu and add the code that generates random numbers into the code to go to the x and y point that we added from the movement menu so that the apples come out randomly in a horizontal place. Here, we write the start...
