Angelscript is a scripting language for embedding into applications to provide custom scripting functionality. It is an object-oriented language with C++-like syntax and semantics.
Here are some of the features and capabilities of the Angelscript language:
1. C++-style syntax: The syntax of Angelscript is very similar to C++, so it is easy for developers who are familiar with C++ to get started.
2. Static type: Angelscript is a statically typed language, that is, variables must declare their type before they can be used. This helps improve code readability and performance.
3. Support object-oriented programming: Angelscript supports classes and objects, allows the creation and use of custom types, and defines encapsulated member functions and variables.
4. Support function overloading: Angelscript allows function overloading, that is, multiple functions can be defined with the same function name but with different parameter lists and return types.
5. Support exception handling: Angelscript provides an exception handling mechanism that can capture and handle exceptions that occur during runtime.
6. Extensibility: Angelscript allows developers to use C++ to extend and customize language features, such as defining custom primitive data types and functions.
7. Cross-platform: Angelscript can run on multiple platforms and is portable, so it can be easily integrated into different applications.
Angelscript is widely used in the field of game development, especially as a scripting language for game logic and event processing. Since its syntax is similar to C++, developers can use it to program various logic and functions in the game, such as character control, AI behavior, game events, etc. At the same time, Angelscript also has good performance and scalability, making it a common scripting language choice in game development.
Will the Angelscript language be eliminated?
At present, the Angelscript language has not been announced that it will be eliminated. Angelscript is a high-performance scripting language developed by Andreas Jonsson and widely used in the field of game development. It provides a concise and flexible scripting syntax that is easy to integrate into existing projects.
Although other languages and technologies may be more popular and commonly used in certain fields and projects, Angelscript still has a certain user base and supporters. Many game developers use Angelscript as a scripting language in their game engines because it provides good performance and ease of use.
In addition, Angelscript is also continuously updated and maintained, and the developer team provides technical support and new functions for it to adapt to the changing programming environment and needs.
However, the popularity and use cases of programming languages may change over time. New technologies and languages are constantly emerging that may create competition for Angelscript. Therefore, whether Angelscript will be eliminated in the future depends on the needs and development trends of its users.

Attached Angelscript quick sort code:
The following is a sample code that uses Angelscript to simulate quicksort:
void QuickSort(array<int>@ arr, int low, int high) {
if (low < high) {
int pivot = Partition(arr, low, high);
QuickSort(arr, low, pivot - 1);
QuickSort(arr, pivot + 1, high);
}
}
int Partition(array<int>@ arr, int low, int high) {
int pivot = arr[high];
int i = low - 1;
for (int j = low; j <= high - 1; j++) {
if (arr[j] < pivot) {
i++;
Swap(arr[i], arr[j]);
}
}
Swap(arr[i + 1], arr[high]);
return (i + 1);
}
void Swap(int& in x, int& in y) {
int temp = x;
x = y;
y = temp;
}
void main() {
array<int> numbers = {9, 5, 2, 7, 1, 3};
QuickSort(numbers, 0, numbers.length() - 1);
for (int i = 0; i < numbers.length(); i++) {
print(numbers[i] + " ");
}
}</int></int></int>This is a typical implementation of the quicksort algorithm. The function QuickSortpartitions the passed in array and recursively sorts the partitions. In Partitionthe function, select the last element as the pivot value (pivot), move the elements smaller than the pivot value to the left of the pivot value, and move the elements greater than the pivot value to the right of the pivot value. Finally returns the position of the reference value.
The main function maincreates an array of integers and calls QuickSorta function to sort it. Finally print the sorted array.
Please note that this example is just to demonstrate how to implement the quicksort algorithm in Angelscript, and does not consider the problems that may be encountered in practical applications such as performance optimization. In actual use, some improvements and optimizations may be required.
