C++ (Cpp) camera_rotateX Examples

Example #1

File: input.c Project: jmikkola/GameEngine

void input_mouseMove (int xPos, int yPos) {
	float halfWinWidth, halfWinHeight, dx, dy;

	halfWinWidth  = (float)WINDOW_WIDTH  / 2.0;
	halfWinHeight = (float)WINDOW_HEIGHT / 2.0;
	dx = ((float)xPos) - halfWinWidth;
    dy = yPos - halfWinHeight;

	// Update direction.
	camera_rotateX( dy * 0.5f);
	camera_rotateZ(-dx * 0.5f);
	// Reset cursor to center
	SDL_WarpMouse(halfWinWidth, halfWinHeight);
}

Example #2

File: main.c Project: seriser6/CS3545

/*
 * input_mouseMove
 */
void input_mouseMove(int dx, int dy)
{
	float halfWinWidth, halfWinHeight;

	halfWinWidth  = (float)WINDOW_WIDTH  / 2.0;
	halfWinHeight = (float)WINDOW_HEIGHT / 2.0;

	dx -= halfWinWidth; dy -= halfWinHeight;

	//Feed the deltas to the camera
	camera_rotateX(-dy/2.0);
	camera_rotateY(-dx/2.0);

	//Reset cursor to center
	SDL_WarpMouse(halfWinWidth, halfWinHeight);
