I have 2 simple capsules. 1 is stationary and the other is moving to the same tile on the tilemap using transform.position.

Both capsules have capsule colliders and rigid bodies. I've attempted to remove the rigid body but from what I can tell, the OnCollisionEnter function requires a rigid body to work.

My script, attached to both of these, is a simple:

I have an if statement in Ruby that combines the == and || operators, and it's quite verbose. What would be a more succinct way to write this:

So I'm currently working on my bachelor thesis and I need to code a class hierarchy (using vector and matrix classes) in order to use methods for solving linear systems.

I coded the basic functions for both classes, and even tried them and they were working. But as I started to add more to the code, I noticed that the functions I used for adding elements to a matrix and displaying them basically stopped working although I don't think I modified them in any way (the same functions I used for the vector class still work).

In a way the functions work, because the couts are displayed, but I don't get to input the values at all.

Here's the vector class (and before you say anything, I don't want to use template):

I've had a lot of issues with this application because I am simply not good enough yet, but I am almost done with it and just want to finish it so I can move on to some slightly lower level projects.

It is a tkinter to-do application.

You can add a Task to a listbox

For every Task, there are some associated attributes, among others: ````self.value = vandself.connectivity = c. The hierarchy of the tasks displayed in the listbox is determined by the value of val_var``` (e.g. the higher the value the higher on the list it will be displayed).

The Task and the associated attributes are determined by the user's input when one creates another task.

The Task is appended to a list task_list and after the user has added more than 1 task to the list, the next time one adds a task one will have the option to check existing tasks that it is connected with somehow.

The list is sorted so the task with the highest value (val_var) is displayed at the top of the Listbox and the task with the lowest value is displayed at the bottom of the Listbox. You can "Save tasks" and then launch the application at a later time where you can then "Load tasks".

Issue 1:

After loading tasks from a saved .dat file, it displays in the Listbox in the order it was saved in. However, if you now want to add another task at least two undesirable things happen:

1. The tasks now loaded into the Listbox are now not displayed as checkbuttons upon adding a new task.
2. When you add another task (again this is after loading the .dat file) the Listbox will delete what was just loaded and the Listbox will only display the newly added task.

I am somehow interested in being able to load the Tasks instances from the .dat file and then append them to the task_list so they are a part of the current session/instance of the application, but I don't know how one might do that.

Issue 2:

On a given session where tasks have been added to the Listbox, they can be deleted from the listbox using the "Delete task" button. The selected task in the Listbox is deleted, but it is not the same task that is deleted from the task_list.

To test what I mean by this one can add a couple of tasks to the Listbox and then delete one after doing so. Notice upon trying to create yet another new task that the one just deleted from the Listbox will still be shown as a checkbutton - however, another task that wasn't just deleted has now vanished as a checkbutton.

Any help with these issues will be sincerely appreciated.

Here's the code:

I create a toolbar menu hierarchy in Outlook using VSTO, CommandBarPopup and CommandBarButton. I set a Click handler on the CommandBarButton's and everything works fine, but I would like to be able to do different things in the click handler depending on whether the user right-clicked on the menu, or shift-left-clicked or what not (for example, to include or not include the original message when automatically composing a template reply).

How do I detect which mouse button the user clicked with, or whether shift, alt, or ctrl keys were pressed when the user clicked?

Total newbie to web development here. I have a Wordpress site where I am using a child theme of the parent theme Go. As part of my site's customer sign up process I have a page with an html form containing a 'select all' survey question with several checkbox inputs. I am experiencing an issue where these checkboxes are not displaying in the form. When I inspect the page in my browser (Chrome) I can see the checkboxes are there, just not appearing.

Here is a link to the page in question: http://www.growopps.net/test/sign-up-3/

I am using CSS in the section of my html. I recently tried putting a border around the checkbox inputs just to see if any of my CSS for the checkboxes was taking effect, but it hasn't; Here is the page's code:

How do I fix the topbar and bottombar doesn't fill up its container. The topbar and bottombar uses the default Elevation respectively

You can see the Top bar doesn't fill max width and it got shadows, while the bottom bar have the text its own compose

This explains the "Bridge" pattern I'm referring to: https://refactoring.guru/design-patterns/bridge

Here's a scenario from the post above:

Say you have a geometric Shape class with a pair of subclasses: Circle and Square. You want to extend this class hierarchy to incorporate colors, so you plan to create Red and Blue shape subclasses. However, since you already have two subclasses, you’ll need to create four class combinations such as BlueCircle and RedSquare.

The problem this scenario presents:

Adding new shape types and colors to the hierarchy will grow it exponentially. For example, to add a triangle shape you’d need to introduce two subclasses, one for each color. And after that, adding a new color would require creating three subclasses, one for each shape type. The further we go, the worse it becomes.

To avoid this problem, we implement the Bridge pattern like so:

Extract the color-related code into its own class with two subclasses: Red and Blue. The Shape class then gets a reference field pointing to one of the color objects. Now the shape can delegate any color-related work to the linked color object. That reference will act as a bridge between the Shape and Color classes. From now on, adding new colors won’t require changing the shape hierarchy, and vice versa.

I understand the how and why of this implementation.

But what if we need a third hierarchy, e.g. BorderStyle (where a border style can be Straight, Wavy, or ZigZag?)

I guess we could implement a second Implementor class for BorderStyle and pass it into a Shape constructor like so:

In my app tree hierarchy, I have a Stateful widget that represents the elements of a list. Let's call this class Item. This Widget contains an Image, some text, and a remove button that should remove the element when it's pressed. Later in the code, I have another Stateful class that holds the ListView and a List of Item which the ListView is created based on it.
My problem is that the onPressed() attribute of every Item is placed inside the item's class and not the upper class (the ListView) in which the remove operation should be handled. How can I fix this? How can I send a signal whenever the button is pressed to the parent widget in order to initiate removing the item?
