Unity2D How to make game object to face opposite from the position of another game object? I have a fish that is going always forward and randomly rotating to make semi random movement, and i want that in range of player(shark) the fish change direction opposite to shark and start moving faster(trying to escape). I have speed increase already but i doknt know how to make the opposite direction.

im trying to reset my car position by pressing Q to avoid the vehicle to be stuck rollover, but when i press Q, there is no cooldown and if i keep pressing the car will go up flying. I dont want that, hopefully someone can help me :> I also wanted to change only the X and Z rotation with the same keycode but im having problems to make it work.

This is the code that i have currently

I have script that works with euler angles and it behaves differently on Windows PC and Android device.

I have the same Matrix4x4 as input but euler angles are not the same.

Test code:

I'm writing some code to generate digits of the mathematical constant e (Eulers number), to any amount of precision.

I am trying to solve Euler 18 in Dyalog APL, and I am not able to understand why my solution does not work.

The problem is as follow:

By starting at the top of the triangle below and moving to adjacent numbers on the row below, the maximum total from top to bottom is 23.

I am trying to build an employee org chart using Highcharts network graph but I'm running into errors. The idea is simple. I want to render an initial chart with the president and a few of their direct reports. After that, if the user clicks on a node in the chart, I want to pull data for that individual's direct reports and update the graph with the children nodes for that individual's subordinates. The back end API for the data pull is working fine

Here is my code:

I'm trying to make a basic FPS game in Unity and I'm having an issue where the projectiles I shoot won't instantiate in the right place. From what I can tell, the projectile instantiates in roughly the same position relative to the player regardless of where I look (that position being a little to the left of the starting angle of the player).

Here's a 20 second video demonstration of what I'm talking about.

Even when I'm facing the exact opposite direction of where the projectile usually instantiates it still spawns in the same place, which means the projectile ends up spawning behind the player and hitting the player.

I tried using Debug.DrawRay() to see if maybe the firepoint itself is wrong (which would be shown by the ray starting somewhere other than the gun barrel). However it seems like the starting point of the ray is correct every time.

I'm not sure if this is related to the issue above, but I have noticed that the ray direction is wrong if I'm looking a little below the horizon. It seems like the projectile's direction is correct regardless though.

Ray directions when looking slightly above the horizon vs. lower

Here's my code for intantiating/shooting the projectile. I think the most relevant parts are probably shootProjectile() and instantiateProjectile(). This script is attached to the player character.

I am working on a project where I need to edit images, I was trying to draw image into canvas but one thing I noticed is when I upload even the same image and check for width and height I sometimes get correct width and height but sometimes 0. Here is what I am doing:

Here I have an input type file and I store it in a state once the FileReader is loaded and then passing to my ImageEditor component

I have the following APL Functions which I want to save in a .dyalog file:
