engineIsModelAllocated

Server-side
NEON APIServer-authoritative models

Available in Neon, not standard MTA

Reports whether a logical model definition is currently active.

Syntax

bool engineIsModelAllocated(int model)

Arguments

modelint

Logical model ID.

Returns

true when the definition exists; false otherwise.

Ownership and lifecycle

The server keeps logical IDs stable, but each client chooses its own GTA slot. When a resource stops, Neon moves surviving elements back to their parent model before freeing those slots.
