How to program the game Cat and Mouse

From the name Cat and Mouse, you can grasp the structure of this game. So let's start programming this game.

Step 1: Choose a wallpaper for the game

To make the game more interesting, the first thing to do is to choose a background. You can choose the scene of the mouse-tailed cat indoors, outdoors, on the beach. by clicking on Choose background in the bottom right corner.

Don't forget to delete the default character if you don't want to use it by clicking on the trash icon next to the character.

Step 3: Programming the Cat character

We need to set up the cat to move flexibly according to our control, thereby quickly catching the mouse. The programming steps for the cat will be as follows:

1. Drag the code When clicking the green flag of the Event section into the programming section.
2. Select Continuous code in Control section .
3. Add Go to the Motion section mouse pointer .
4. Point towards the object (_) in Motion. The (_) part selects the object as the mouse.

Step 4: Programming the Mouse character

To make the mouse run everywhere and hide from the cat, you will need to program it as follows:

1. Drag the code When clicking the green flag of the Event item into the programming interface.
2. Add Continuous under Controls .
3. In the Motion section , add Glide for (_) seconds to random position. The (_) box should be set to 1 so that the mouse moves at a moderate rate.
4. Finally add Restart if edge touched also under Motion.

To make the game more vivid, you can add sound for the mouse every time it is caught by the cat by programming as follows:

1. Add If code (_) then make it a child of Continuous code. In (_) add Touching code (_) and select cat character.
2. Insert the Start Sound code (_) under the Sound section . In the (_) section you can set the sound to match the mouse when it is caught by the cat.

You can also set it up so that every time it is caught, the mouse will disappear and reappear in another location.

1. Drag the Hidden item in the Show as a child of the If (_) then code.
2. Insert code Go to random position under Move down.
3. Add the Wait (_) seconds code under Controls . In the (_) section you can set the number of seconds to wait for the mouse to reappear in the game interface.
4. Finally, insert the Show code in the Display section.
