seesaw | Routing , backwards and forwards | Router library

I am using the strategy described here to run the standalone karate.jar along with a custom jar (implementing a LogModifier):

I'm making a 2d shooter in Ue4. I'm trying to rotate a sprite to face the mouse. The sprite will later be a hidden arrow that determines the directions the bullets go when they spawn. The sprite was added to help me visually debug. Since the game is 2d, the sprite should only need to rotate around the Y axis.

The sprite is not rotating correctly. As I move the mouse pointer around the edge of the game's window: rather than spin 360 in a circle, it seesaws back and forth (see second image).

I figured this was a radians or worldspace issue, but I've done the basic troubleshooting I know how. The first image is the cleanest version of the blueprint that produces the error. I've tried ATAN, ATAN2, and GetMousePosition solutions, all of which look a bit different than this.

In the sprite images, the red circle shows where my cursor is. The red arrow is just to help determine the angle the sprite is tilted at (they're all wrong). The top of the round bit (90 degrees CCW of the red arrow) is what should be facing the mouse. The sprite's default, unrotated position, has the round bit pointing up towards the top of the screen. Of note, the actual rotation and the desired rotation all seem to be off by a multiple of 90 degrees, but this might be a coincidence.

Any ideas on what I'm doing wrong?

How to parse 3 character alpha with multiple or conditions? All text is uppercase [A-Z].

This is, I guess, a pretty common scenario for anyone doing performance studies. Suppose one has a few data structures, and would like to evaluate their space performance -- without counting using e.g. sizeof but rather in an empirical way. I model this situation in an MWE as follows:

• there is an STL stack and there is a set
• first I create the stack and push some (random) numbers into it
• I delete the stack, and push some numbers into the set
• I run valgrind --tool-massif --max-steps=1000 --time-unit=ms main
• finally, I visualize using the eponymous `massif-visualizer'

The code:

Subscriptions with Nexus are undocumented but I searched Github and tried every example in the book. It's just not working for me.

I have cloned Prisma2 GraphQL boilerplate project & my files are as follows:

in kivy-language, I would like to change the angle value of the canvas every time when a slider changes its value by on_touch_move.

I have tried to give the "Rotation Operation" in the PushMatrix an ID by using "group"

I have a list like the following:

Hi I'm just new to unity2d, so I have a gameObject that has an hinge joint attached to another gameObject with rigidbody, Im trying to make a Wooden board that will behave like a "seesaw" and return back to its current position when the character is not set foot on it. How can I make it behave like a seesaw thanks!

This is the Original position of the gameObject where the other end of the wood is inclined down.

This should what must happen when my character puts weigh on the opposite end help please.

This is something I found difficult to research as it requires some explanation.

I basically want to understand the best way of moving objects around other objects and keep track of where everything is. Allow me to explain..

Let's pretend we are making a Person class and a Park class. The park class has a bunch of toys and rides for the person to play on.. These could be a Slide class, SeeSaw class, ect.. But lets say our program needs to keep track of where the Person object is at all times. If they are on the slide, we will want to ask the person class their location. For example...
