Warnings And Failures

IMPORTANT!

Token Variables - along with the Gauge API - have been deprecated in Microsoft Flight Simulator 2024 in favour of the new Vars API and Event API, which work with the more extensive and supported Simulation Variables and Key Events.

This page lists the available warning and failure Token Variables for use when creating gauges using WASM / C++.
