UnigineScript Containers
You can work with UnigineScript containers from C# side via Unigine API, that is, with:
See also
An example can be found in <UnigineSDK>/source/csharp/samples/Api/Scripts/Arrays/ directory.
Container Export Example
Unigine vectors and maps can be accessed via:
- ArrayVector class and the ArrayVector.get() function for vectors. The ArrayVector::get() C++ API function and the ArrayVector C++ API class have the same behavior.
- ArrayMap class and the ArrayMap.get() function for maps. The ArrayMap C++ API class and the ArrayMap::get() C++ API function have the same behavior.
C# Side
Create setter and getter functions that receive Unigine containers and handle their elements. Then, export the created functions in order to use them in the script.
You should specify the array declaration as the last argument of the Function if your array functions receive an array as an argument.
The postfix of Function shows the number of arguments (up to 8 arguments) and the type of return value:
Function(my_array_vector_set,"[]")
- no postfix - void.
- i - int.
- d - double.
- f - float.
- s - string.
- v - Unigine.Variable (the same class as the C++ API Unigine::Variable class).

Access from Script
And here is how the exported custom functions can be used back in UnigineScript:
// array.cpp
/*
*/
int init() {
/////////////////////////////////
log.warning("\naccess to vector\n\n");
int vector[] = ( 0, 1 );
for(int i = 0; i < 2; i++) {
log.message("vector %d: %s\n",i,typeinfo(my_array_vector_get(vector,i)));
my_array_vector_set(vector,i,string(i));
log.message("vector %d: %s\n",i,typeinfo(my_array_vector_get(vector,i)));
}
/////////////////////////////////
log.warning("\naccess to map\n\n");
int map[] = ( 0 : 0, 1 : 1 );
for(int i = 0; i < 2; i++) {
log.message("map %d: %s\n",i,typeinfo(my_array_map_get(map,i)));
my_array_map_set(map,i,string(i));
log.message("map %d: %s\n",i,typeinfo(my_array_map_get(map,i)));
}
/////////////////////////////////
log.warning("\nvector generation\n\n");
my_array_vector_generate(vector);
foreachkey(int i; vector) {
log.message("vector %d: %s\n",i,typeinfo(vector[i]));
}
/////////////////////////////////
log.warning("\nmap generation\n\n");
my_array_map_generate(map);
foreachkey(int i; map) {
log.message("map %d: %s\n",i,typeinfo(map[i]));
}
/////////////////////////////////
log.warning("\nvector enumeration\n\n");
my_array_vector_enumerate(vector);
/////////////////////////////////
// show console
engine.console.setActivity(1);
return 1;
}
Output
The following result will be printed into the console:
access to vector
vector 0: int: 0
vector 0: string: "0"
vector 1: int: 1
vector 1: string: "1"
access to map
map 0: int: 0
map 0: string: "0"
map 1: int: 1
map 1: string: "1"
vector generation
vector 0: int: 1
vector 1: int: 4
vector 2: int: 9
vector 3: string: "128"
map generation
map 1: int: 1
map 4: int: 4
map 9: int: 9
map 128: string: "128"
vector enumeration
0: int: 1
1: int: 4
2: int: 9
3: string: "128"
