v7 beta documentation in progress. v7 beta documentation may be incomplete or inaccurate.
v7 functions and features may be significantly different from previous ACS versions.
The MCH (Mechanic Computer HUD) is a HUD for programming ACS features and injecting scripts. It a no-tranfser object only for registered ACS owners.
In order to connect the Mechanic HUD to the vehicle, place the +Mechanic Tool+ script inside the vehicle, then with the HUD on, touch the vehicle to connect the HUD. You can then inject scripts or use other setup functions.
The MCH connects to the vehicle via the v7 Mechanic Tool script. The v7 Mechanic Tool script should be removed from the vehicle when you are finished building/scripting the vehicle and are ready to distribute it.
The first beta set includes only the standard prim version of the Mechanic Computer HUD. The faster-response mesh edition will be available ASAP.
