symmetry – What are all the possible symmetrical map designs? (on a flat 2d surface)

If we look at the following ‘square’ map:

Square Map - 4 symmetrical nodes

… we have the possibility of creating a repeating pattern of 4 equidistant ‘nodes’ (where the distance between could be ‘scalable’).

If we look at the following ‘hex’ map:

Hex Map - 3 symmetrical nodes

… we have the possibility of creating a repeating pattern of 3 equidistant ‘nodes’ (where the distance between could be ‘scalable’).

Are these the only two possibilities?… if not, what shapes/nodes am I missing? Is there an equation that defines these?

java – Why does ‘get’ method of class ‘Map’ enable sending a not relevant key without a compilation error?

I just had a bug in my program, but i don’t understand how the program was compiled at all!

I have the following variable:

gamesPerCountriesMap: MutableMap<Long, MutableMap<Long, MutableList<AllScoresGameObj>>>?

and i had the following line of code:

var gamesList = gamesPerCountriesMap?.get(

the correct line should be:

var gamesList = gamesPerCountriesMap?.get(

i have looked at the prototype of the Map class and the method is declared as following:

public inline operator fun <@kotlin.internal.OnlyInputTypes K, V> Map<out K, V>.get(key: K): V?

As we can see it can get K and it’s subtype, but competitionItem which is an instacne of class CompetitionObj isn’t inherit the Long class.
So why the compiler didn’t prevent this error? I solved the issue but i am very couries of what is didn’t prevent the code from being compiled?

unity – Touch control pan 3D map

I’m working on recreating the board game “Hex” as a mobile game. I’m working on implementing zoom and pan features using two fingers. I feel like I managed to get the zoom to work, but the pan moves more than I want it to and I feel like it is because I’m missing something and must be somewhere in the conversion to World Space coordinates. if I could get some help it would be greatly appreciated.

For reference, oldMidpoint is initialized to 0 earlier on.

        Touch touchA = Input.GetTouch(0);
        Touch touchB = Input.GetTouch(1);

        Vector3 midpoint = (touchA.position + touchB.position) / 2;
        if(midpoint != oldMidpoint)
            if(oldMidpoint ==
                oldMidpoint = midpoint;

            Vector3 moveDistance = oldMidpoint - midpoint;
            moveDistance.y = 0;

            Camera.main.transform.Translate(moveDistance, Space.World);

            oldMidpoint = midpoint;

Separar en partes un map ordenado nodejs

Tengo el siguiente código

currency.sort((a, b) => b.balance - a.balance)
        .filter(user => message.client.users.cache.has(user.user_id) && !message.member.roles.cache.some(role => === 'admin'))
        .map((user, position) => `**#${position + 1}** ${(message.client.users.cache.get(user.user_id).tag)}: ${user.balance}`)

El código ordena una lista de usuarios en base a quién tiene mas "monedas", y escoge los 10 primeros y los mapea para darle un formato. Hasta ahí todo bien.

El objetivo ahora es que en vez de guardar todos juntos, el primero con mas monedas, el segundo, los siguientes 4 y los últimos 4 formen parte de strings diferentes, ¿Cómo podría hacerlo? he probado varias cosas pero no he conseguido que funcione.

python – How to load a new map when player reaches a certain point using if == ‘door” (pygame)

I have been working on creating a 2d game, and I am now at the point where I want the character to be able to interact with his environment, I have created a few different obstacles such as a house, fence and a wall is it possible to load a new map when the player reached the tile named “door” I have it written out as if == ‘door’: but not sure what to load after that so that a new map loads when he reaches that obstacle named door any help would be greatly appreciated 🙂 I have attached my code below for

rpg maker – Using a custom map gui disables the ability to save

I’m quite confused at the moment. I’ve created a custom gui (a fuel display on map) that works nicely, but somehow whenever I try to save the game when this gui is active….clicking on the slot where I want to save the game does not work!

thus when I add the following code and let it be called via a trigger (a common event which has a switch as trigger calls this javascript code…event runs parallel with a wait (5)):

REITD.SpaceClass.prototype.showCargoAndFuelStatusUI = function (vehicleType, currentCargo, maxCargo, currentFuel, maxFuel) {
    if (!(SceneManager._scene instanceof Scene_Menu)) {
        if ($gameSystem._REITD_definedWindows("CargoAndFuel") !== undefined) {

        $gameSystem._REITD_definedWindows("CargoAndFuel") = new Window_Base(new Rectangle(1, 1, 211, 200));

        $gameSystem._REITD_shownStatusUIWindows("CargoAndFuel") = "shown";

        $gameSystem._REITD_definedWindows("CargoAndFuel").drawText("Vehicle Fuel", 1, 5, 190, "center");
        $gameSystem._REITD_definedWindows("CargoAndFuel").contents.fillRect(1, 40, 200, 25, _Colors.gray);
        $gameSystem._REITD_definedWindows("CargoAndFuel").contents.fillRect(1, 40, 2 * this.calcFuelPercent(vehicleType), 25,;  // 2 px per percent full.
            padLeft(this.getCurrentFuel(vehicleType), 6, "0") + " / " + padLeft(this.getMaxFuel(vehicleType), 6, "0"), 30, 35, 100, "left");

        $gameSystem._REITD_definedWindows("CargoAndFuel").drawText("Vehicle Cargo", 1, 75, 190, "center");
        $gameSystem._REITD_definedWindows("CargoAndFuel").contents.fillRect(1, 110, 200, 25, _Colors.gray);
        $gameSystem._REITD_definedWindows("CargoAndFuel").contents.fillRect(1, 110, 2 * this.calcCargoPercent(vehicleType), 25,;  // 2 px per percent full.
            padLeft(this.getCurrentCargo(vehicleType), 6, "0") + " / " + padLeft(this.getMaxCargo(vehicleType), 6, "0"), 30, 105, 100, "left");

I’m running into the problem.
Now my question is:
Why is that so and what can I do to correct this problem (or can I somehow deactivate this while a menu is open?)

c++ – Getting data from the backbuffer D3D11 using Map

I’m having some trouble using ID3D11DeviceContext::Map() correctly.

Here’s the whole function so far:

 Color Graphics::GetPixel(int x, int y) const
    //Temp frame buffer descriptor;
    CD3D11_TEXTURE2D_DESC pFrameDesc;
    pFrameDesc.Width = WindowWidth;
    pFrameDesc.Height = WindowHeight;
    pFrameDesc.CPUAccessFlags = D3D11_CPU_ACCESS_READ;
    pFrameDesc.Format = DXGI_FORMAT_B8G8R8A8_UNORM;
    pFrameDesc.MipLevels = 1u;
    pFrameDesc.ArraySize = 1u;
    pFrameDesc.SampleDesc.Count = 1u;
    pFrameDesc.SampleDesc.Quality = 0u;
    pFrameDesc.Usage = D3D11_USAGE_DEFAULT;
    pFrameDesc.BindFlags = D3D11_BIND_UNORDERED_ACCESS;
    pFrameDesc.MiscFlags = 0u;

    // Create temp frame buffer(2d texture)
    wrl::ComPtr<ID3D11Texture2D>pFrame = nullptr;
    HRESULT hr = pDevice->CreateTexture2D(&pFrameDesc, nullptr, &pFrame);

    hr = pSwapChain->GetBuffer(0, __uuidof(pFrame), &pFrame);
    map.RowPitch = WindowWidth * 4;
    map.DepthPitch = WindowHeight * 4;
    //Throwing here, CPU access flags problem. 
    hr = pContext->Map(pFrame.Get(), 0u, D3D11_MAP_READ, 0u, &map);

    pContext->Unmap(pFrame.Get(), 0u);

    return { 0.0f, 0.4f, 0.0f, 0.0f };

I’m getting an exception thrown at pContext->Map()

“Map cannot be called with MAP_READ access, because the Resource was not created with the D3D11_CPU_ACCESS_READ flag. “

Which is confusing as the newly created resource has the D3D11_CPU_ACCESS_READ flag enabled. This is also true If I try MAP_WRITE and change the access flags to match. I’ve also tried ORing the flags together with no luck.

The ultimate use of this function is to be able to create a CPU side array of Color objects (Colors are currently a struct of four floats) Which I can then send onto the NewTek NDI sdk. But I feel it would also be useful for saving screen shots, creating colour pickers etc.

Any ideas welcome!

Map data structure terminology – Computer Science Stack Exchange

I’m looking for the correct terminology in regard to map (dictionary) data structure.

When I’m talking about the semantics of the values stored in map in the direction from keys to values, I’d say, for example

messages keys are mapped to message strings

When I’m using the opposite direction – describing the values first, I’d need to say something like

message strings are ??? by message keys (“being mapped by” just doesn’t feel right here)
