how would i make a sprite go in front and behind a 2d wall? I've tried a few solutions but none seem to work. first, I tried adding half of that same sprite onto the original and then making the layer higher, which would work, except my original sprite can walk so far behind the wall that only its head is sticking out from behind, so if I were to use that strategy I would only be able to add the top of its head, otherwise you would see half the sprite go over the wall while walking behind it, which would look weird. the second option I saw was making different parts of the tilemap walls different layers, but for my specific tilemap, I am unable to unless there is some way of making each individual tile multiple layers. any ideas?
Issue with Sorting Layers with an NPC and Tilemap I have a weird thing happening, that I can't quite explain.  I have two scenes, my starting town, and an Arcanist's shop.  When I go into the Arcanist's Shop, the Arcanist NPC stays on the same sorting layer (background layer 0) as my checkered tiles, and the table is background layer 1.  When I start the game, the NPC will switch between being "behind" the table, or on top of it whenever I reenter the Arcanist's Shop scene.  It seems to switch between background layer 0 and 1 with no cause.  I've double checked my sorting layers, they're all where they should be.  I've checked the camera's culling mask, it's fine.  I've checked to see if there are any weird components on anything in my shop scene, and there aren't  See the image attached, this is the same instance of the game, just different times when I enter the Arcanist's Shop.

How to get distance when acceleration is not constant? I have a background in calculus but don't really know anything about physics.  Forgive me if this is a really basic question.  The equation for distance of an accelerating object with constant acceleration is:  $$d=ut        +\frac{1}{2}at^2$$  which can also be expressed  $$d=\frac{\mathrm{d}x}{\mathrm{d}t}t+\frac{\mathrm{d^2}x}{\mathrm{d}t^2}\frac{t^2}{2}$$  (where x(t) is the position of the object at time t)  That's fine for a canonball or something like that, but what about a car accelerating from 0 to cruising speed?  The acceleration is obviously not constant, but what about the change in acceleration?  Is it constant?  I suspect not.  And then what about the change in the change of acceleration, etc. etc.?  In other words, how does one know how many additional terms to add in the series?  $$d=\frac{\mathrm{d}x}{\mathrm{d}t}t+\frac{\mathrm{d^2}x}{\mathrm{d}t^2}\frac{t^2}{2}+\frac{\mathrm{d^3}x}{\mathrm{d}t^3}\frac{t^3}{3}+\frac{\mathrm{d^4}x}{\mathrm{d}t^4}\frac{t^4}{4}\cdot etc. \cdot ?$$ How do I run an executable using Lua? Incorrect whitespaces or list item size in Android SE app Noticed that sometimes when there are 10+ answers to a question - some answers look like they have \n\n...\n line breaks in the end, so the body of the answer has incorrect height.  It probably has something to do with ViewHolder or adapter not setting correct row height. Although as far as I know, it should do this according to text amount/length. How can I know if a branch has been already merged into master? I have a git repository with multiple branches.   How can I know which branches are already merged into the master branch? I've used a number of different *nix-based systems of the years, and it seems like every flavor of Bash I use has a different algorithm for deciding which startup scripts to run.  For the purposes of tasks like setting up environment variables and aliases and printing startup messages (e.g. MOTDs), which startup script is the appropriate place to do these?  What's the difference between putting things in .bashrc, .bash_profile, and .environment?  I've also seen other files such as .login, .bash_login, and .profile; are these ever relevant?  What are the differences in which ones get run when logging in physically, logging in remotely via ssh, and opening a new terminal window?  Are there any significant differences across platforms (including Mac OS X (and its Terminal.app) and Cygwin Bash)? I already searched the internet but could not find a solution to this. Maybe it is the same question as  but there was no answer.  I want to render a video with tracking, but the output "loses" color information and gets kind of greyish. I first thought that it is related to the renderer, but it happens in Cycles and Eevee. Therefore i made a sample image, added it to the image sequence editor and rendered it as 1 frame. Resulting in the same problem.  I placed the original image beside blenders output so that you can see the difference. The only idea I came up with is that something with the lighting is not correct but I can't find a setting for that.  I am using Blender 2.80 with the default settings. Only set the output resolution to match the input resolution. prevent php classes from being extends My wife is an Indian national with an Indian passport.

Proof that no term (of a language of predicate logic) is a (non-empty) initial segment of another Ubuntu can't be installed on my system because of what the title says. This is because support Intel HD Graphics 530 was only just added in Linux kernel 4.3 and all versions of Ubuntu only have kernel versions up to 4.2 as of 15.10.

So in the image below there are two circles, how can I remove the internal vertices between them without messing up the outside shape. I'm working on a gun and this is just a simple way to illustrate the issue I'm dealing with. If I where to go in and delete the internal faces it would leave holes on the outside of the object, is there a fast way to get around this? In linear regression, when is it appropriate to use the log of an independent variable instead of the actual values?

I was trying to install minted package in TeXLive. I installed it and then run sudo tlmgr update --all. It was running slow so I stopped it using Ctrl+Z in an ubuntu terminal and then I run sudo tlmgr update --list. After that I installed texlive-latex-extra and python-pygments.

I have been experiencing an issue that once I have a material created and looking the way I want it, I cannot seem to export it correctly with the textures mixed.  I don't know the correct words to use, but in blender I have the material created using the nodes editor, and I have placed two textures inside of there (one for the rock texture and one for moss, my object is a rock). When I export this model and import to Unity (the game engine I am using), I find a materials folder but the material inside of it does not have the textures assigned, it's just a plain white material?  How can I export my material from blender in a way that it will allow me to import it WITH TEXTURES into Unity? What issues should be considered when overriding equals and hashCode in Java?

For example,  was downvoted to -2 and answered with a link to an FAQ page that no longer exists. Is it acceptable to begin a declarative sentence with "Am"? I want to know firstly if it's grammatically correct to start a declarative sentence with "Am". For example:     Am excited about the game today.   Secondly, if it is grammatically incorrect, then I wanted to ask how much "head room" there is for the above usage. I can't think of an example now, nor find one here at english.stackexchange. However I imagine there are usages of the english language that grammatically are illegal, yet have somehow become accepted as colloquial or idiomatic perhaps. I've read that abelian categories can naturally be enriched in $\mathbf{Ab}.$ How does this actually work? Wikipedia defines the notion of an abelian category as follows ().     A category is abelian iff         it has a zero object,   it has all binary products and binary coproducts, and   it has all kernels and cokernels.   all monomorphisms and epimorphisms are normal.      It later explains that an abelian category can naturally be enriched in $\mathbf{Ab},$ as a result of the first three axioms above.  How does this actually work?
