Sprite touching anything

Ask_Pinkamena

I have searched for a solution on the forums, and correct me if I am wrong, there is no topic on a touching anything script. What I want to do is have one sprite perform a certain action upon contacting any sprite. I know I could use a broadcast on every sprite, but I am hoping there is a faster alternative as a single script. Any help is appreciated.

Edit: By anything, I mean anything (other sprites, the edges, anything BUT the background).

you could use

<<<touching [sprite1] ?> or < <touching [sprite2] ?>>> or <<touching [edge] ?> >>

but this might cause lag if there are a lot of sprites. An improvement on this would be

if <(distance to [sprite1]) < [50 ]> then
if <touching [sprite1] ?> then
broadcast [do something]
    
end
else
if <(distance to [sprite2]) < [50 ]> then
if <touching [sprite2] ?> then
broadcast [do something]
    
end
else
if <touching [edge] ?> then
broadcast [do something]
    
end

    
end

    
end

this works faster because the distance to block works faster than the touching block. You need to put a value where I've put 50 that is approximately the smallest distance between the centres of the two sprites when they are nearly touching. This way your script will only use the laggy touching block if the two sprites are near enough to touch. Hope this makes sense!

This could work. Thanks!

I guess you could just have multiple scripts for each of the sprites. Or maybe a creative use of the More Blocks tab.

You probably haven't heard of me, but I have a few projects in the works you may be interested in!

If your a Five Nights at Freddy's fan that wants to play the game but doesn't have the money and all the scratch ones are too laggy and incomplete on your computer? Well, then I have the project for you. I have began to remake the first game and make it so it doesn't have all of the effects and unnecessary graphics that made the game laggy. It will eventually become a full project will all the gameplay of the original game, but I need your help! Check out the project here, it is in early stages of development. To be an alpha/beta tester, check it out here

Stay tuned for more projects by following me at NeoProHex

While I appreciate the response, I am looking for a single script answer. Your second answer could work for what I need.

i would love an answer to this because i am creating a dynamic inventory (which means that when you pick up an item it can go to any slot not just a set one). But my problem is that there is a chance that you might pick up two items at the same time and if you do that the dynamic inventory gets messed up with the items being on top of each other. The only way i could fix this is by having scripts that say if touching this or this or this which if i am trying to make a lot of items wouldn't be efficient so what i want is a script that can sense if i am touching anything else except this. (this is my game btw https://scratch.mit.edu/projects/95030060/#player)

Ok i found a way to do this, I found out that if you type the exact name of all your sprites into a list and then tell the sprite to sense if it is touching anything in that list it will do something. An example i made would be this project https://scratch.mit.edu/projects/101852148/#editor

when green flag clicked
forever
    
move (10) steps
if on edge, bounce
if <touching color [#ff0209] ?> then
stop [all v]
    
end
if <touching [Paddle v] ?> then
turn ccw (100) degrees
    
end

end

this is when the ball touches red line fail hard

your welcome

this should be added because it would be useful and save a LOT of time. the “if touching ()” block was updated to a select list to select multiple items.

<touching [ anything] ?>

and

<touching [ edge, mouse-pointer, sprite1] ?>
