c++ – Easy methods to use handles for asset administration?

The best way I’ve realized to implement an asset supervisor is having unordered maps for every asset sort (textures, shaders, meshes, and so forth.), every with a string key and object worth after which having strategies Add(), Get(), Load() for every asset sort. For my ability degree and the dimensions of tasks I will be doing that is in all probability adequate, nevertheless, I got here throughout a weblog that makes use of the idea of handles which I discovered fairly fascinating. It reveals a deal with as a wrapper round a uint32_t after which goes on a few supervisor class that follows the same construction to what I mentioned.

What I do not perceive about this strategy is how do you affiliate a deal with with a object? With the tactic I have been utilizing because it’s simply strings I can simply create an object and retailer the ID in it

AssetManager::AddTexture("Textures/participant.png", "PlayerTexture");
AssetManager::AddMesh("Meshes/participant.obj", "PlayerMesh");

// This might technically be written anyplace
Scene::AddObject(GameObject("Participant", "PlayerTexture", "PlayerMesh"));

AssetManager::GetMesh(Object.MeshName);

static Mesh GetMesh(std::string ID) {
    return  meshes[ID];
}

However with handles would not I must make my object proper after loading the asset? Or how else am I purported to get the deal with to the article until I proceed to make use of string IDs however for the handles, however I really feel like that may defeat the aim. Here is an instance of making an attempt to grasp utilizing handles.

TextureHandle playerTextureHandle = AssetManager::AddTexture("Textures/participant.png");

// Must be right here so I can entry the variable
Scene::AddObject(GameObject("Participant", playerTextureHandle));

AssetManager::GetTexture(Object.textureHandle);

struct TextureHandle {
    unsigned int deal with;
}

static Texture GetTexture(TextureHandle deal with) {
    return textures[handle.handle];
}

Penning this put up one other potential drawback may be the very fact I do not perceive what a deal with absolutely is so I’ve a sense I won’t be utilizing it within the supposed manner.
