GetPCRunning behavior different from vanilla?

[ImpendingDoom]

While trying to fix some of the issues with the various sailable ship mods (Fishing Academy, Stormrider, etc.) I ran into an issue with how OpenMW appears to handle the 'GetPCRunning' function. It appears that while vanilla Morrowind takes this as a command to check if the player is actually running, OpenMW just checks if run mode is active (ie. shift/capslock is pressed). This manifests itself in the script governing plyer control over the ship - when pressing W while in run mode, boats and ships immediately shoot up to maximum speed instead of gradually incrementing up with each keypress.

The offending segment of code is here:

if ( sailmode == 1 )
	if ( GetPCRunning == 1 )
		if ( ScriptRunning, "bmultiplier_script02" == 0 )
			startscript "bmultiplier_script02"
		endif
	endif
endif

if ( sailmode == 1 )
	if ( GetPCRunning == 1 )
		if ( bgear == 1 )		
			if ( sspeed < 20 )				; max speed can be adjusted here ( default = 20 )
				set sspeed to ( sspeed + 1 )
				if ( gps == 0 )
					set fishtype to 0
				endif
				if ( sspeed > 20 )
					set sspeed to 20
				endif
				messagebox "Boat Speed : %.0f", sspeed
			else
				messagebox "Boat Speed : %.0f ( max. )", sspeed
			endif
		elseif ( bgear == 2 )
			if ( bauto == 0 )
				if ( sspeed != 0 )
					rotate, z, -60
					set oangle to getAngle, z
					if ( oangle >= 0 )
						set boatangle to ( oangle - 180 )
					else
						set boatangle to ( 180 + oangle )
					endif
				endif
			endif
		elseif ( bgear == 3 )
			if ( bauto == 0 )
				if ( sspeed != 0 )
					rotate, z, 60
					set oangle to getAngle, z
					if ( oangle >= 0 )
						set boatangle to ( oangle - 180 )
					else
						set boatangle to ( 180 + oangle )
					endif
				endif
			endif
		elseif ( bgear == 4 )
			if ( sspeed > 0 )					; min speed can be adjusted here ( default = 0 )
				set sspeed to ( sspeed - 1 )
				messagebox "Boat Speed : %.0f", sspeed
			else
				set sspeed to 0
				messagebox "Boat Speed : 0 ( Stopped )"
			endif
		endif
	else
		stopscript "bmultiplier_script02"
	endif
endif

GetPCRunning indeed checks only run mode in OpenMW:

Code: Select all

MWWorld::Ptr ptr = MWBase::Environment::get().getWorld ()->getPlayerPtr();
runtime.push (ptr.getClass().getCreatureStats(ptr).getStance(MWMechanics::CreatureStats::Stance_Run));

GetPCSneaking behaves in the same way.
Can you investigate how these functions behave in vanilla Morrowind?

If there is a difference between OpenMW and Morrowind, feel free to create a bugreport.
