How To Get the Mouse to Follow You on Scratch?

Let’s make a Mouse Trail game on Scratch today. In the above graphic, you can see sprites [cat, ball] following your mouse pointer and creating Mouse Trails with various effects [color, position, shape, transparency]. The steps involved in making of this Mouse Trail game on Scratch have been explained below:

  1. Pick a sprite
  2. Create a clone of the sprite
  3. Add more effects to the mouse trail
  4. Switch the object (sprite) 

How to Make Mouse Trail Effect Scratch Game?

The detailed step-by-step process involved in making a Mouse Trail game on Scratch is explained below:

Step 1: Pick a sprite [Cat]

  • Let us choose the first object you wish to click.
  • If you want to select a different sprite for this Mouse Trail, delete the cat sprite.
  • You may have a mouse trail made up of scratch cats, hearts, stars, balloons, rainbows, or anything else you like!

  • Click on the “Choose a Sprite” icon.
Click on the 'Choose a Sprite' icon
  • Let’s start by creating a Scratch cat trail.
  • Click on Cat, you can pick any character from scratch’s library of sprites.
Click on Cat
  • After clicking on Cat, you will be able to see the cat in the stage area. 
  • Make the cat follow your mouse pointer.

  • From the motion category drag & drop the “go-to” random position block.
  • Click on the menu and choose “mouse-pointer”.
choose 'mouse-pointer'
  • Put the “go-to” block inside a forever loop and click on it.
  • Here you can see the cat is always going to your mouse pointer.

  • Click on the green flag icon to begin the movement. As a result, the sprite follows your mouse when you click the green flag.
  • “When the green flag clicked” can be moved up by dragging.

Step 2: Create a clone of the sprite

You now have one sprite, not precisely a mouse trail, following your mouse. Now make several Scratch cats follow your mouse pointer to create a trail. Here are the steps to achieving this:

  • Drag “make a clone of myself” from the control box and then click it.
  • Anywhere you click “Make a clone of myself”, a new Scratch cat is created.
click "Make a clone of myself"
  • These cat clones can also have multiple moves by using programming.
  • Drag and drop the piece labeled “when I start as a clone.”
  • You can place any code under there, and when clones are made, they will execute that code,
when clones are made
  • When creating a Scratch clone, change the color of the cat.
  • Select the color and its value of 25 by dragging and dropping the “change effect by” block.
Select the color and its value of 25
  • You can see changes in color when they’re created by clicking on the “create a clone of” block.
clicking on the "create a clone of" block
  • You might include a repeat loop and make a few color changes.
  • The “repeat” block should be moved around as seen below.
"repeat" block
  • This clone can be added to or removed.
  • Drag & drop “delete this clone” block as shown below.
Drag & drop 'delete this clone'
  • Put the “create a clone of myself” block inside the forever loop,
  • Drag and drop the “create a clone of myself” block to the “forever” loop and underneath to the “go-to” block.
  • Click on it and move your mouse pointer over the screen.
  • Here you can see that after their color is changed, they disappear off the screen.
  • And now you can drag the cat around and wherever it goes, it creates a clone.

Note:- It is usually not recommended to have a “create a clone of myself” block inside of a forever loop, because if a sprite creates too many clones, the computer will run really slowly. The reason it is okay here is that when a clone is created, it does a little animation, but then it gets deleted. So, you can never get too many clones.

Step 3: Add more effects to the Mouse Trail Game

  • You can add different kinds of things inside an infinite loop to get different effects.
  • From the motion category, drag and drop the “change X by 10” block inside the repeat loop.
  • Click on the “green flag”.
  • So now when you are creating the clones, they are changing their color and they are also having a movement on the screen because of the “changing X by 10” block.
  • Similarly, you can also add the change in the Y block.
  • Drag & drop the “change y by 10” block as shown below.
  • Click on the “green flag”.
  • Now clone cats are changing their color and then they’re going upward.
  • To make it a falling effect you can change Y by a negative value.
  • Change the 10 to -10 as shown below. 
  • Click on the “green flag”.
  • Let’s make the items in the Mouse Trail spread out in every direction.
  • Drag & drop “point in direction” and “pick random” blocks as shown below and click on them.
  • Make a sprite point in a certain direction and if you put the block “pick random” and put the value “zero to 360”, then it will point in a random direction from zero to 360 degrees.
put the block "pick random"
  • And if you add the “move 10 steps” block and click on it, it makes the sprite go forward in whatever direction it’s pointing.
add the “move 10 steps” block
  • Drag & drop the “point in direction” & “pick random” blocks as shown below.
  • Drag & drop the “move steps” block as shown below.
Drag & drop the 'move steps' block
  • Click on the “green flag”.
  • If you make the clones point in a random direction, and then put them inside the repeat loop & you move 10 steps, then before you start the repeat loop, they point somewhere random and then they repeatedly move in that direction 10 times. And that’s how you can get this explosion effect.

Step 4: Switch between the sprites

  • If you ever want to switch the objects in your Mouse Trail, you can just click on the “costumes” tab and pick a new costume.
  • Let’s try something else other than the cat.
  • Click on the “Costumes” section.
Click on the 'Costumes' section
  • Click on the “Choose a Costume”.
Click on the 'Choose a Costume'
  • Click on the “Ball-e”
Click on the 'Ball-e'
  • Click on the “Code”
Click on the 'Code'
  • Click on the “green flag”.
  • You can try putting in a “change size by” block and put in a negative number[-8], and then the items will get smaller as they go out.
  • Drag & drop the “change size by” block as shown below.
Drag & drop the 'change size by' block
  • Click on the “green flag”.
Click on the "green flag"
  • You can fade them as they go outward, or you can put in a change ghost effect block. If you change the ghost effect of a sprite, it gets more transparent.
  • Drag & drop the “change effect by” block and click the menu and select “ghost” effect.
Drag & drop the “change effect by” block
  • Set the ghost effect by value five. 
Set the ghost effect by value five
  • Click on the “green flag”.
Click on the "green flag"

Congratulations! you have completed the mouse trail game on Scratch!
