DrawPoints | Android App ) Sample code | Android library

I am new to this kind of mathematics and didn't have it in school jet. So my problem is the change from spherical coordinates to a grrid (radius and angle to x and y). First I devide the circle in even angles. Until here everything works. When they get transformed they have all the same distance to the center but seam to be random in rotation. This can be well seen with low numbers like 4. The final purpose of the project will be to draw a cardioid for that I need a circle with points. So here my code:

• in editor
• in build

I am currently trying to get my growth algorithm to work on a texture.

When running in the editor everything works as expected, however once I build the project, the whole RenderTexture becomes a solid color (red, green or blue [R8G8B8A8_UNORM] depending on the color format) with the simulation on top.

I have already tried to use an HDRP unlit texture shader instead of my custom transparency shader, which produced the same issue leading me to believe that my mistake lies somewhere within the compute shader drawing onto the texture. Also, I rebuilt the project using URP which unfortunately also produced the same result.

One other thing, I recently noticed that minimizing and maximizing the game window on runtime in the editor more than once crashes unity although I can't image how this has anything to do with the issue at hand.

EDIT: Just built the same project for windows (DX11) which works perfectly. This therefore seems to be an issue with the Metal API.

Interestingly, the maximizing/minimizing problem appears only if vsync is enabled and the touchpad gesture is used.

Unity Version 2021.2.12f1 using the HDRP on MacOS Monterey 12.2.1.

I have created a SamplePainter that inherits from CustomPainter as shown below, and in it, I am trying to create cartoonish screen tones using PictureRecorder.

When I try to use that screen tone to draw a shape using the paintImage function, I get an exception ("Object has been disposed.").

If I try to use canvas.drawImage instead, I get the same exception. What is the problem?

For example, point 1 connects to point 9, then point 2 connects to point 10 and so on for len(pointList).

I am currently stuck because once the turtle attempts to access the 32nd point, it gets an out of bounds error because the point it would need to connect to is point 0 but it wont do so with my current code.

Each point will need to connect to the 9th point ahead of it for the length of the list (40 in this case because of the text file line amount)

I am hinted to use % operator, but I do not know how I would use it.

As the title states, I am trying to detect a mouse hover over an object that is not a JComponent. Right now I have a window with a green JPanel. When you left-click on this JPanel you create a point.

What I am trying to do is to have extra information displayed when I hover over these points. However, I have no idea how to even begin detecting if I am hovering my mouse over a point. I tried looking into the MouseListener interface but I could not find any examples of people using MouseListener with an object. I have only seen people use MouseListener with JComponents. I would preferably like to have this mouse hover detection code in my Point class if possible to keep my code clean.

I get this most common error message in shiny app. I am well aware of this error and have resolved it dozens of time. But this time I am stumped.

I have been trying to plot a time series using dygraph in R. It seems that we can only pass in a dataframe with the dates and their values. All other columns will be automatically ignored. Here I have reproduced my data and the resulting graph:

I get error : Unhandled exception at 0x00007FF89F84AFEC (ucrtbased.dll) in Opencv.exe: An invalid parameter was passed to a function that considers invalid parameters fatal.
