game.hs_function_call

This function was added to the Halo: The Master Chief Collection build of Halo: Reach in mid-July 2023, being backported from Halo 4's Megalo engine. Gametypes that use this function will likely fail to load on Xbox 360 builds of Halo: Reach (even when played via Xbox One backward compatibility).

This function allows you to invoke HaloScript functions defined and made available to Megalo on the current map. Maps can make HaloScript functions available by writing the function names into the msit tag.

Arguments

function ID

The HaloScript function name to call. ReachVariantTool has no way of reading any extra names defined in your map file, so use numeric indices here.
