I have created a sample project to explain this better.

When you open the settings app on iPad, the right side of the screen shows the general settings and the left side shows the general settings navigation link selected

But when people open my app on the right side of the screen is the “Hello” page but on the left, the hello navigation link is not selected

The output of this image from gdalinfo 20141030-wv03.tif is like this:

I know this question has been asked many times, but I still can't figure out what to do (more below).

I'm trying to spawn a new thread using std::thread::spawn and then run an async loop inside of it.

The async function I want to run:

I'm using Mapbox GL to color dynamically countries. Some of the countries are red, some are green.

For this, I'm using the country-boundaries-v1 source, then I use the iso_3166-1 data from country-boundaries to set a filter on the layers that use the country-boundaries source.

This is the code where I add my layers:

I try to make a bouncing bullet for a game that should disappear after bouncing 3 times. I thought it's simple, I gave my bullet a variable with the value of 3 and decreased it in my bullet-platform collider by one.

After it didn't work and checked the variable with console.log(), I found out that the variable gets decreased continuously. I tested my other colliders and found out that only the bullet-platform collider do that, while the player-platform, enemy-platform, bullet-player and bullet-enemy collider don't. In addition my function for destroying bullets, when they hit a platform, oddly work fine. My bullets only get destroyed when hitting a platform.

Does anyone have an Idea how to fix that?

Edit: I made a Github repository of my game for better insight. (At least I hope I did, I haven't used Github before.) https://github.com/Kiroho/Game

Edit2: After testing around, I found out that it must have something to do with how I use my ammoGroup class.

I found out that, if I create bullets via ammoGroup (via createMultiple), the collider starts firing for each bullet until I shot them at least once. After all existing bullets are fired once, everything works normally and the collider fires as intended -> only on collision.

After reading a large json file and capturing only the 'text' column, I would like to add a column to dataframe and set all rows to a specific value:

I am currently trying to implement Ambient Occlusion in a simple Voxel Renderer, each block is rendered (unless not visible) with 24 vertices and 12 triangles, so no meshing of any kind.

I followed this tutorial on how ambient occlusion for minecraft-like worlds could work, but it didn't explain how to actually implement that in shaders / graphics programming, so what I've done so far are only my uneducated best guesses.

The basic idea is, for each vertex to generate a value from the surrounding blocks about how "dark" the ambient occlusion should be. (Nevermind my values being completely wrong currently). These are from 0 (no surroundings) to 3 (vertex completely surrounded) The picture in the tutorial I linked helps to explain that.

So I tried that, but it seems to not darken the area around a vertex, but instead the whole triangle, the vertex is in... How do I make it not do that? I am a total beginner in shaders and graphics programming, so any help is appreciated :D

Here is my vertex shader, the inputs are

• position of vertex
• normal of vertex
• tex_coord in texture atlas
• tile_uv: position on block (0 or 1 for left/right bottom/top)
• the ambient_occlusion value
