One of the features I want to include in my mod is an anti-capital weapon that has a short 'spool up' time before firing. It's mostly intended as a countermeasure against players using the ludicrously powerful weapon against fighters and bombers.
The issue is, $Submodel Rotation Speed and $Submodel Rotation Acceleration appear to do nothing.
The Blue Planet team managed to successfully do this with the Gattler. I tried copying the Gattler's table entry into my own .tbl, then modifying stuff to match the prior weapon, but it still doesn't work. According to the wiki, an external submodel that rotates should not be necessary to get the weapon 'charge up' delay working.
Is there some other piece of code I am missing?
