Getting Vehicle Engine RPM

[ClareXoBearrx3R9]

Hello everyone,

 

Does anyone know of a method to get the engine RPM of a vehicle? I'd like to work on a tachometer but it seems that no natives exist for such a function. I'm a C and C++ programmer, so hopefully some combination of methods within the ScriptHook SDK that would work exist.

 

I looked around and found some GetVehicleRPM() in the .NET SDK that appears to access data from the memory but I'm not familiar with .NET.

 

Thanks in advance

Looks like you'll need to access the data from memory then. Since the .Net ScriptHook does it, and its source is available, I'd check the .Net ScriptHook's source code.

Was trying to avoid having to do that but it seems that what's necessary. Thanks!

extern float GET_VEHICLE_ENGINE_REVS(int vehicle);

Works on new natives only, so PC version

Here's what i use for a simple displayer using scocl to compile.

if ( DOES_VEHICLE_EXIST(G_MYVEH) ){	static float speed = 0.0f;	static uint delay = 0;	GET_GAME_TIMER(&gtimer);	if ( delay < gtimer )	{		delay = gtimer + 333;		GET_CAR_SPEED(G_MYVEH, &speed);		speed *= 2.94f;	}	int revs = 0;	float frevs = GET_VEHICLE_ENGINE_REVS(G_MYVEH);	frevs *= 10.0f;	revs = (int) frevs;	register float x = 0.08f;	register int i;	for ( i = 0; i < revs; ++i )	{		if ( i > 8 ) SetFont( 255, 0, 0 );		else if ( i > 6 ) SetFont( 255, 213, 0 );		else SetFont( 0, 255, 0 );		DISPLAY_TEXT_WITH_LITERAL_STRING(x, 0.68f, "STRING", ">");		x += 0.008f;	}	SetFont( 33, 148, 219 );	DISPLAY_TEXT_WITH_LITERAL_STRING(0.08f, 0.70f, "STRING", "Gear:");	SetFont( 219, 104, 33 );	DISPLAY_TEXT_WITH_NUMBER(0.135f, 0.70f, "NUMBER", GET_VEHICLE_GEAR(G_MYVEH));	SetFont( 33, 148, 219 );	DISPLAY_TEXT_WITH_LITERAL_STRING(0.08f, 0.72f, "STRING", "Mph:");	SetFont( 219, 104, 33 );	DISPLAY_TEXT_WITH_NUMBER(0.135f, 0.72f, "NUMBER", (int) speed);	DRAW_CURVED_WINDOW(0.0752f, 0.679f, 0.089f, 0.0645f, 255);}

?!

 

it's a DLC2 function, should work fine on consoles if you just use the non-altered hash (i.e. the reproducible one) for it, though they might only be enabled when setup2 indicates episode 2

Wow - thanks!!! I'll definitely give that a try!

 

On a sidenote, I did find that native previously but was disappointed to find that it was only in TBoGT. Regardless, I'll give it a shot; again!

Er, what value would GET_VEHICLE_ENGINE_REVS output, if the car revs are, say, 2000? Is there a Rockstar version of the revs? I'm creating a script, and I was going to use if (VehicleRevs < 2000) etc. but... Would the revs be that high? Would it output just 2?

 

Any help would be greatly appreciated.
