Camera folllowing car

[siny]

Hi,

I'am having a problem with camera. I want it to follow car. W tried:

Code: Select all

		vector3df carPos = carnode->getPosition();
        actualCamera->setPosition(core::vector3df(carPos.X+800,carPos.Y+800,carPos.Z));
	    actualCamera->setTarget(core::vector3df(carPos.X-800,carPos.Y,carPos.Z));

But it don't works like those ones from games. It rotates around the car depends in which way i turn.

How to force it to stay at the back of car and look in the direction of ride??

You'll have to transform your 'relativetocar'-vector so that it rotates. It can be done like this

Code: Select all

vector3df RelativeToCar(0,0,-100);
CarNode->getAbsoluteTransformation().TransformVect(RelativeToCar);
CameraNode->setPosition(RelativeToCar);
CameraNode->setTarget(CarNode->getAbsolutePosition());

Then your RelativeToCar will always be 100 units behind the car, no matter what rotation your car has, since the vector is also transformed.
