The MouseWheel property provides the current state of the mouse wheel as a Vector2. This property is static and can be accessed without instantiating the Input class. It is useful for detecting mouse wheel movements, which can be used for zooming, scrolling, or other input actions in a game.
To access the mouse wheel state, simply use the MouseWheel property from the Input class. The Vector2 returned represents the movement of the mouse wheel, where the X component typically represents horizontal scrolling and the Y component represents vertical scrolling.
// Example of using the MouseWheel property
Vector2 mouseWheelState = Input.MouseWheel;
// Check if the mouse wheel has been scrolled up or down
if (mouseWheelState.y > 0)
{
// Mouse wheel scrolled up
// Implement zoom in or scroll up functionality
}
else if (mouseWheelState.y < 0)
{
// Mouse wheel scrolled down
// Implement zoom out or scroll down functionality
}
