[Tutorial] Fix Helicopter

[Dennis Albert]

Hey,
just a small fix to the Helicopter physics:

just search for:

void obj_Vehicle::HelicopterPhysx()

Replace the whole Text with:

void obj_Vehicle::HelicopterPhysx() // controls of helicopter
{
	PxVec3 NormGravity(0,-9.81,0);
	if (isHelicopter == true)
	{
		const float fTimePassed = r3dGetFrameTime();
		PxTransform pose = vd->vehicle->getRigidDynamicActor()->getGlobalPose();
		r3dVector angles;
		r3dPoint3D position(0,0,0);
		PxVec3 HeliGravity(0,0,0);

Nice fix , it also adds free invisible jetpack when zombie dies ( ͡° ͜ʖ ͡°)

 

[Dennis Albert]

Yes it's funny, but edited the code for 2 minutes it should fixed now
Fixed now.

I think I obamabf2 already posted something about it

 

[Dennis Albert]

I know there is a tutorial from obama but the helicopter is still a little buggy, so if you use that you cant control it good.
