The scope of applications for UnigineScript is limited to implementing materials-related logic (material expressions, scriptable materials, brush materials). Do not use UnigineScript as a language for application logic, please consider C#/C++ instead, as these APIs are the preferred ones. Availability of new Engine features in UnigineScipt (beyond its scope of applications) is not guaranteed, as the current level of support assumes only fixing critical issues.

The foreach construct is used to iterate over vectors and maps.


Source code (UnigineScript)
foreach(value_variable; container; loop_increment) { 
	// some_code;


  • value_variable is the value of the current container element.
  • container is a vector or a map.
  • loop_increment is executed at the end of each iteration.

On each iteration, the value of the current element is assigned to value_variable and the internal container cursor is moved to point at the next container element. The type of value_variable doesn't matter. loop_increment is optional.

Modifications of elements inside the foreach block affect the container; synchronization occurs at the end of each iteration.


  • For each vector element:
    Source code (UnigineScript)
    int vector[4] = ( 1, vec3(1,2,3), -7.2e-2, "end" );
    foreach(int i; vector) {
    The example displays the following:
    int: 1
    vec3: 1 2 3
    float: -0.072
    string: "end"
  • For each map element:
    Source code (UnigineScript)
    int map[] = ( 1 : "begin", 2 : 2, 3 : "end" );
    foreach(int i; map) {
    The result is:
    string: "begin"
    int: 2
    string: "end"
  • Increment:
    Source code (UnigineScript)
    foreach(int i, j = 0; vector; j++) {
    	log.message("%d: %s\n",j,typeinfo(i));
    The output is:
    0: int: 1
    1: vec3: 1 2 3
    2: float: -0.072
    3: string: "end"
