Hello Scratchers. This is my second game I created.

I was left wondering why is there not a block that allows combining “if” with “sprite is clicked”. Is there a way to achieve this? - there is only “when sprite is clicked”

My plan is to have a script randomly appear. Once it appears, it will wait for either 0.5 seconds or if sprite is clicked, then it will disappear and appear randomly in time again.

Since I could not find “sprite is clicked”, i created this humongous chunk of code in my project,
https://scratch.mit.edu/projects/420120272

This is what I usually do, but may not be the most efficient.

forever
if <<touching [mouse pointer v] ?> and <mouse down?>> then
code here
end
end

Cool trick. What doesn “mouse down” mean? Click and hold?

And why it may not be efficient?

mouse down is if the mouse click is held down. It isn't efficient because sometimes other scripts may run after this block, but it will slow them down.

The code that MopperFat1 suggested should work, but if you want the script to only run when the sprite is clicked and not held, you'll need to add a bit more code:

forever
if <<touching [mouse pointer v]> and <mouse down?>> then
wait until <not <mouse down?>>
...
end
end

<mouse down?>

is true if the left click button is currently pressed/held down.
is false otherwise

Thanks a million for the advise Scratchers. I really like that Scratch has a platform where people can ask questions. Really help a beginner like me to learn.

i tried your suggestion. Although it greatly reduces complexity of my codes, i feel like it only works if one presses the mouse button and hold, releasing after 2 secs. Hmm. May I ask if this is how it should work?

New program file based on your recommendation:
https://scratch.mit.edu/projects/420369935

There is only one built-in timer and you have multiple scripts resetting it. The sprites are then waiting 2 seconds during which you can't click them. You probably want one master control script managing the timer. The sprites should wait until two seconds have passed OR they have been clicked.

Yay it worked!

another variant of this (if u only want it to check if the player clicked the mouse once) is:

Any event :: events hat
wait until <<touching [mouse pointer v] ?> and <mouse down?>>
if <<touching [mouse pointer v] ?> and <mouse down?>> then
...
end

U can also use the when sprite clicked hat block. Start by making a variable “clicked?”

when this sprite clicked
set [clicked? v] to [1]
wait (0.1) secs
set [clicked? v] to [0]

... // Then from somewhere else from the code when u want to check
if <(clicked?) = [1]> then
... //code
end

Also u might wanna add some delay & add the if statement to possibly some loop or something so that you wait until the user has clicked the sprite in question

Hope it helps!!!!
