I need help with mouse trails

gawocko20

I would like to add mouse trails to my project clicky clicker linked HERE
but I can't find a way! can someone help please?

Spentine

There are many kinds of mouse trails, so i'm going to show you one example.

when green flag clicked
hide
forever
go to [mouse pointer v]
wait (0.1) secs
create clone of [self v]
end

when I start as a clone
show
go to front
point in direction (pick random (0) to (359))
clear graphic effects
repeat (20)
change [ghost v] effect by (5)
move (2) steps
end
delete this clone

Of course, I just yolo'd the code and I don't know if it actually works or not. You can give it a try if you want.

Spentine's mouse trail could work if you want something like that, but we don't know what you want. What kind of mouse trail are you looking for?

You can take a look at a sample Mouse Trail template here: https://scratch.mit.edu/projects/555145507/

wydm by clicking through the mouse trail?

it probably means, since the mouse trail is always at your mouse position and it's in front of everything else, you're always clicking on the mouse trail itself, and the other sprites don't respond to your clicks because you are not clicking on them, you're clicking on the mouse trail

i don't have a solution yet but you should clarify that in the top post so everyone else knows what the problem is

Yes, that is what I mean and I would really like help! Even the wikis are wrong! :O

Hello! If you have a problem with clicking through your mouse trail, you could always have the mouse trail never spawn on the mouse cursor directly but rather around it and make it so that they disappear quickly.

Hi gawocko20,

Here's a technique that seems to work. I keep track of a past mouse location and create a trail element only when the mouse is a small distance away. The trail element clone (a star) is created in that past location, so it appears just behind where the mouse is moving, and looks right. I took it one step further and have the clone delete itself immediately if it is touched by the mouse while fading away.

Demo: Mouse Trail - Click Friendly
https://scratch.mit.edu/projects/721744134/

Attempted Clicks counts the number of times the mouse goes up and down. Successful Clicks counts the number of clicks received by the full screen nebula sprite.

Even attempting to move the mouse back quickly and click over a star, the counts remain the same. (It may not be impossible, but it's very very rare.)

I hope this helps. I'm happy to answer any questions.

That would work, but I need the sprite to stay visible while the mouse clicks.

Try if touching mouse trail and mouse down? then…

Hi gawocko20,

Disregard. See Spentine's answer below.

I assume this is for Clicky Clicker? If so, I see you have a round button you need to click, which is the easiest shape for this.

The idea is that you'll watch for the mouse to go from being up (not down) to being down, which tells you there's a click “somewhere”. Then you just need to see if that “somewhere” (where the mouse is) is inside the circle your button is drawn in. There's a “distance to mouse pointer” that makes this easy, because you just have to see if that distance is less than the radius of your circle.

I've shown how it works here:

Demo: Click Through Another Sprite (circle)

I hope this helps. Happy to answer any questions.

At this point, don't use the

when this sprite clicked

block.

Do

when green flag clicked
forever
if <mouse down?> then
if <touching [mouse pointer v] ?> then 
your code here :: grey
end
wait until <not <mouse down?>>
end
end

instead.

The

<touching [mouse pointer v] ?>

block doesn't care if it's being obscured by mouse trails.

Oh, thanks Spentine!

I saw that on the wiki.

I tried that. It still triggers if the sprite is hidden.

I think you're saying that sometimes the button you would click on is hidden, so shouldn't be able to touch the mouse pointer.

Scratch doesn't let you check whether a sprite is shown or hidden with a block, so you would have to keep track yourself, using a variable.

Whenever you have a show or hide block:

show
set [showing v] to [true] // add this

hide
set [showing v] to [false] // add this

And then you can modify Spentine's code as

when green flag clicked
forever
if <mouse down?> then
if <<(showing) = [true]> and <touching [mouse pointer v] ?>> then // check showing
your code here :: grey
end
wait until <not <mouse down?>>
end
end
