Some interesting 3rd person shooter code

[java_man]

Well it kinda works to a point, I was trying to come up with a simpler way of doing it:

Code: Select all

bool CDemo::OnEvent(SEvent event)
{
		core::vector3df model_rotate;
		scene::ICameraSceneNode* camera = 0;
		scene::ISceneManager* sm = device->getSceneManager();
		camera = sm->getActiveCamera();
		core::line3d<f32> line;
		line.start = camera->getPosition();
		line.end = line.start + (camera->getTarget() - line.start).normalize() * 75.0f;
		model_rotate.Z = 0;
		model_rotate.X = 0;
		model_rotate.Y = 0;

		switch(event.KeyInput.Key)
		{
			case KEY_KEY_A:
				{
					++Big_Rotate;
					if (Big_Rotate > 359) {
						Big_Rotate = 1;
					}
					break;
				}
			case KEY_KEY_S:
				{
					--Big_Rotate;
					if (Big_Rotate < 1) {
						Big_Rotate = 359;
					}
				}

		}
		model_rotate.Y = Big_Rotate;
		model_rotate.X = 20;

		model3->setPosition(line.end);
		model3->setRotation(model_rotate); 

With the code above you can change the position of the player like a gun turret...etc...

Haven't figured out how to connect it to the FPS camera in terms of rotation.
Big_Rotate is defined as an int and initialized to 1. Was trying to use:
model_rotate.X = 20; to tilt the gun. It's not the best way to do it, but I think it maybe an easier way to do it.

I've seen other 3rd person shooter code examples, but they seemed kinda lengthy and sometimes would't compile at all.
