3rd Person Camera

[Kiki]

I fixed during some hours this..... but at last I could run my programm using Code::Blocks but the character stayed at the ground and it's not possible to make it move...... has anybody out there a solution for this problem.... please...... I will very grateful about this........
Thanks in advance.......

luvcraft,I tried to use your code in my own game. It's successfully compiled, but when I start program, it doesn't work. In Debug mode yellow arrow appears on this

Code: Select all

core::vector3df sonic_movedir = sonic_target->getAbsolutePosition() - sonic->getPosition();
		if(moving) {
			sonic->setPosition(sonic->getPosition()+(sonic_movedir*moving));
			moving=0;
		}

		/*
		That's it for moving the player. Now here's the stuff for moving the camera.
		While we want to camera to look directly at p1, we want its movement to be based on
		a point HEIGHT above p1.
		*/
		camera->setTarget(sonic->getPosition());
		f64 distance = camera->getPosition().getDistanceFrom(camera->getTarget()+core::vector3df(0,HEIGHT,0));
		core::vector3df cam_movedir = (camera->getTarget()+core::vector3df(0,HEIGHT,0))-camera->getPosition();
		cam_movedir.normalize();

		/*
		The camera tries to stay between 50.0f and 50.0f+MOVESPEED from HEIGHT above p1;
		if it tried to stay at exactly 50.0f, it would freak out and jiggle too much.
		*/
		if(distance>(50.0f+MOVESPEED))
			camera->setPosition(camera->getPosition()+(cam_movedir*MOVESPEED));
		else if(distance<50.0f)
			camera->setPosition(camera->getPosition()-(cam_movedir*MOVESPEED));

		/*
		The camera rotation stuff cheats a little, because instead of rotating it perfectly
		around p1, it just moves the camera left or right relatively, and lets the camera
		automatically adjust to the right distance.
		*/
		if(cam_rotate) {
			core::vector3df crossy = (camera->getTarget()-camera->getPosition()).crossProduct(camera->getUpVector());
			crossy.normalize();
			camera->setPosition(camera->getPosition()-crossy*cam_rotate);
			cam_rotate=0;

What can I do to avoid it?
