Variadic Functions in UnrealScript
Here’s a function that will take an arbitrary number of ints as arguments.
class VariadicFunctions;
static function sum(int nums(a)) {
local int i, total;
`log("Nums: " $ nums.Length);
total = 0;
for (i = 0; i < nums.Length; i++) {
total += nums[i];
}
`log("Total: " $ total);
}
static function main() {
local array<int> nums;
// Variadic functions can be called in the usual way with individual arguments.
sum(1, 2);
sum(1, 2, 3);
// If you already have multiple args in an array, you can apply them to a variadic function in UnrealScript like this.
nums[0] = 1;
nums[1] = 2;
nums[2] = 3;
nums[3] = 4;
sum(nums);
}To execute the code, you can run it as part of an UnrealScript project. The log output will show the arguments passed to the variadic function and their sums.
$ ucc make
$ ucc exec packageName.VariadicFunctions.mainLog output will be:
Nums: 2
Total: 3
Nums: 3
Total: 6
Nums: 4
Total: 10Another key aspect of functions in UnrealScript is their ability to form closures, which we’ll look at next.
