QUESTION
I'm trying to duplicate scrolling effect like airpods, it was working but it has some effects when scrolling as attachment.
I loaded 94 images to make it scrolling 360deg and preload 148 of images. I know that the scrolling effects can be removed if I use ScrollTrigger JS plug in but I want to build this by using vanilla JS only.
How can I remove the effects (When scrolling) on the image?

...ANSWER
Answered 2021-Mar-24 at 09:40On first glance I can see that you need to bind the function click
and not it's execution result. Change your event listener line to table[i].addEventListener("click", click)
.
Also I think you meant to use textContent
and not textComment
inside click
.
QUESTION
At the moment I'm struggling to combine attributes of my markers and polygons on my leaflet map.
In my map I have bavarian government districts with the name of the districs as attribute. And I have 70 markers to show the location of some mountains in these districts, these points are from an csv table I made.
What I wanted to do now is that each point should be assigned the attribute of the corresponding district within it lies. So that the marker popup also shows the name of the district. I don't know whats the easiest way to do this? So I thought about using the turf points within polygon function but I'm not sure how to start.
Map with Marker and Polygons.
The second thing I wanted to do, is to highlight the highest mountain. The mountain with the largest number in the second column. Mountain height.
My table is looking like this: (mountain name;mountain height;area;landscape;lat;long)
Bergname;Berghoehe;Landkreis;Gebirge_Landschaft;Latitude;Longitude
Hesselberg;689;Ansbach;Wörnitztal_Fränkische Alb;49.06861780;10.52610990
Dürrenberg;656; Weißenburg-Gunzenhausen;Hahnenkamm; 49.01647480; 10.76511290
...
I hope someone can help me out here, would be much appreciated :)
ANSWER
Answered 2021-Jan-05 at 15:35You can use turf.booleanContains(district.toGeoJSON(16), marker.toGeoJSON(16))
to check if the marker is in the district and then add the popup.
Add your markers to a FeatureGroup to get it later for the loop
QUESTION
I've made a leaflet map and was trying to implement turf. As a quick test, I just wanted to put a buffer around one of my markers. But somehow I can still only see the two markers on my map. I basically followed the steps from this document. https://lib.dr.iastate.edu/gis_tasksheets/3/ I'm not sure where I made a mistake, I hope someone can tell me.

You have to swap your coords in the turf.point

QUESTION
I want to check if a column entry matches a city on a list of cities (region), if there is a match, then I want to add to a column a string with the region zipcode (region_name) and if it does not match then I want to keep the current column value.

- AssertionError with pandas when reading excel
- https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.replace.html and https://www.w3resource.com/pandas/series/series-replace.php It says here, "Raises AssertionError if regex is not a bool and to_replace is not None." I'm not 100% clear what that means.
I tried a new library (modin) and made a few changes (including installing pylint as prompted by a popup) and afterward, replace() no longer worked with a column.

QUESTION
I cannot for the life of me figure out what I am going wrong here, I have done the code over and over, I have checked for errors, spelling etc. Maybe it's something I don't understand, or something my eyes are correcting, but every time I run the program and try to move the ball it gives me the error in the image attached.
Any help would be greatly appreciated. Thanks.
...ANSWER
Answered 2020-Jul-08 at 17:12You are calling Ball:update(dt)
, which is subtly different from what you really mean to call, which is ball:update(dt)
. See the difference?
In the first one, you are writing valid code, because Ball
is a class definition that you've created. You are allowed to call methods on class definitions themselves, but only if they're 'static' methods - that is, methods which don't touch any members of the class (such as self.dx
). If they try to, it won't work because those members haven't been initialized - it's a class definition, it can't have members with values.
ball
, on the other hand, is an instance of Ball
, which means it has members with values, and can have non-static methods (such as update
) called on it.
(Also, you're doing the same thing for Ball:reset
, although you've done it right with ball:render
.)
