When working on game development projects in C++, it is common to use data structures such as std::array to store collections of related objects. In this blog post, we will explore how to initialize an std::array of game development objects using uniform initialization.
Uniform initialization is a feature introduced in C++11 that provides a more consistent and concise syntax for initializing objects. It allows you to initialize objects using curly braces {}, which can make the code more readable and reduce the chance of errors.
To demonstrate the initialization of an std::array of game development objects, let’s assume we have a GameObject class that represents a game entity with a name and a position:
#include <array>
class GameObject {
public:
GameObject(const std::string& name, const std::array<float, 3>& position)
: name(name), position(position) {}
private:
std::string name;
std::array<float, 3> position;
};
Now, let’s initialize an std::array of GameObject using uniform initialization:
std::array<GameObject, 3> gameObjects = {
{"Player", {0.0f, 0.0f, 0.0f}},
{"Enemy", {10.0f, 5.0f, 2.0f}},
{"Obstacle", {-5.0f, 2.0f, 0.0f}}
};
In the above code, we create an std::array called gameObjects with a size of 3. We initialize each element of the array using uniform initialization syntax. Each element is initialized with a GameObject by providing its name as a string and its position as an std::array<float, 3>.
By using uniform initialization, we can create and initialize an std::array of GameObject objects in a single step, making the code more concise and readable.
It is worth noting that uniform initialization can also be used when the GameObject class or its members have default or non-default constructors. Uniform initialization will call the appropriate constructor to initialize the objects correctly.
In conclusion, uniform initialization provides a cleaner and more readable way to initialize objects, including std::array collections of game development objects. By leveraging this feature, you can make your code more concise and easier to understand, leading to more efficient game development.
