Plus it could make some projects non-computer friendly, and that's just weird.
do you not know what i am talking about you only have one mouse coordinate only so you can only press on one sprite and humans do not have only one finger they have ten so they can press the screen at ten different areas of the screen and i am suggesting a way to detect whether one of those touches are touching a sprite so you can have ten sprites being touched at once but you can only have one sprite being clicked at once people do you not read the entire thing

and you can probably make non-computer friendly projects anyway using current methods since when they track your mouse x and mouse y in mobile there is no light gun or something tracking your finger when its off the screen so it only tracks where you touched meaning that movements go from one point to another in an instant while on a computer you can't do this so when you want your mouse to go from point a to b your mouse goes through many points between a and b until you finally reach the goal

Can you please add punctuation and capital letters to that? It's somewhat hard to read.

I'm not sure what you're saying you can make mobile-only games because on mobile taps “jump” from point to point. How would a project detect that without getting needlessly complicated? Frankly, I don't support this. There really isn't a need for this; how exactly this would be useful? Scratch was meant for computer and built for computer. Do people actually use Scratch on mobile devices, if so I must give them a round of applause for navigating a website meant to be displayed on a computer on a smaller screen. As well as that, there would be mobile-only projects. PC-only projects do exist in the form of anything that uses the keyboard.

Maybe change title of topic to “multi touch events.” Touch event sounds like what Scratch already does.

SPEAK UP TO KUMQUAT EQUALITY Kumquats are not bad! Kumquat lives matter!

hi i am myself, i make projects that take like a week or month to make whenever i feel like it (which isn't often) and then they only get 10 views because i'm a nobody. and i cannot change that. i am just one singular person in the sea of many that are on scratch. my stuff don't matter. i don't matter. i am going to die in 70 years anyway, and 99.99% of people on the world will not even know, or really care if they know. also i am good at programming i made an opengl so ha take that nuuubs. (i am legally required to say that statement does not accurately reflect my views i wrote that because i thought it was funny)

all my good projects. are here here are examples of my good Projects

shoot that's it basically lol they're all platformers. play them and talk about it so i get clout plz. thank.

In a forever loop, you can check if the mouse delta is above a certain threshold. If it is, then it probably means that the user is using a touchscreen, which is present in all smartphones.

when green flag clicked
set [mobile? v] to [no]
set [last mouse x v] to (mouse x)
set [last mouse y v] to (mouse y)
forever
if <(distance function too lazy to write it all out (mouse x) (mouse y) (last mouse x) (last mouse y)::operators) > ["certain threshold," say 5]> then
 set [mobile? v] to [yes]
end
set [last mouse x v] to (mouse x)
set [last mouse y v] to (mouse y)
end

Support! This actually wouldn't be hard to implement. But I think that this should be either a multitouch extension

when this sprite touched :: pen hat

<this sprite touched? :: pen>

or multitouch compatibility could be added to

when this sprite clicked

and

<touching [mouse-pointer v]?>

Scratch 3.0 is compatible with mobile devices, and people do use the website on mobile devices. So I think that mobile-only projects would be OK.

On a phone, Scratch looks like this.

Scratch doesn't support multi-touch anyway, as far as I can tell. If it did, “when this sprite clicked” blocks can be used just fine.

It currently doesn't support multi-touch, but that could (should) be added.

However, a very, very small fraction of the userbase uses mobile.

I think because almost all devices at least either support touch or have a keyboard, these blocks should be included in the core set so a project can be made for devices without keyboards. The key _ pressed? block is not of an extension, but not all devices have a keyboard, so why not these blocks too?

Touches can move between two points; that's how they detect scrolling. Scratch 3.0 is also made for touchscreen tablets. While the parts of the website from the 2.0 era are not optimized for smaller screens, the redesigned pages do work well enough.

As the OP said, supporting the detection of multiple pointers would be useful for having both a joystick and a jump button, for example. It could also be used to detect zoom and rotate gestures

try this

when green flag clicked
forever
go to [mouse pointer v]
end

move (ved_chinnamgari :)) steps

Workaround:

when [timer v] > (0)
forever
reset timer
if <touching [this sprite v] ?> then
...
end
end

No, I don't think so, it's just showing the forum that I made that has the new blocks that I created for this topic.

This question is very hard. I would like to see if we can get something like this.

Hello, I am making "4 DRIVERS", a simple multiplayer game on one screen.
With a keybaord no problem but I use this for touch screen:

<<mouse down?> and <touching [ mouse pointer] >>

but multitouch don't work.
Do you have another solution?
When do you think it can be implement?
Thanks and sorry for my bad English.
