redbox | a distributed musical instrument

I am trying to make one single, straight line follow my finger after I touch a certain sprite object. I have it working so far except instead of one single line being drawn, infinite lines are drawn following the touch...

My Code:

I want to create custom tags in html to do some sort of thing like is there any way to turn html and css divs into tags?

I recently started developing in Swift (normally embedded C developer).

I want to create some button (later more than one) programmatically and change its label (just for practice). For this I created a button class, which contains the button init and the callback function. My problem is that it seems like the #selector is not pointing to the instance of the button class the way I expected it will, so a button click does nothing. Can you tell me what I am doing wrong?

For example let's create two rectangles. Then we select these two rectangles and want to see their coordinates:

ok,maybe its my noobness,but i cant wrap my head around this particular problem

In this test we have a button with id #add-div which purpose is to append the same div with class .container to body on every click.

We also have another button with id #add-boxes which purpose is to append a red box with class .redbox to every div with the .container class.

the .container div has a button inside which does the same thing as the #add-boxes button.

Lets say we have a scenario where we throw a couple of divs there,and we also fill them with 2 boxes each like this :

and then we add another div which is empty like this :

what is the logic i should follow to make sure the new div will appear with the same amount of red boxes inside it as the previous ones like this : ?

snippet to visualize my concept :

The docs for styled-components show its default styled export accepts a single argument:

styled

This is the default export. This is a low-level factory we use to create the styled.tagname helper methods.

Arguments

component / tagname

Description

Either a valid react component or a tagname like 'div'.

I've emphasized "valid react component" here because they explicitly aren't saying this has to be a React component created by styled, although traditionally that is how this is used (as well as documented under their Extending Styled section). An example of this is shown below:

I have an excel file as the following:
I am trying to take the string in the left of the comma by using the function in the Redbox =LEFT(A2;FIND(",";A2;1)-1). It worked well with the category that had a comma but I want if there is not a comma, It shows the string in the category instead of #value!

I'm trying to make a UI system similar to GMOD's vgui library (https://wiki.facepunch.com/gmod/vgui). In this library you can create an element, then child of that element. The child of a parent element will be clipped by the parent element's size. So if you have a redbox that has a width and height of 100, the the child element's of the redbox CANNOT be drawn outside the redbox and so on.

I tried measuring the height of a view by using coordinatespace on it but the value it returns is the height of the full screen. Any idea why my code isn't giving me what I want ?
