Camera zoom

[gmoller]

Hi, I'm trying to use the Camera to be able to zoom in and out using the mouse wheel. I'm using the following code that I found online, but the update translation line does not compile:

pub(crate) fn move_camera_system(
mut mouse_wheel_events: EventReader,
mut query: Query<&mut Transform, Withbevy::render::camera::Camera>
) {

for mut transform in query.iter_mut() {
    // Camera Mouse Zoom
    for event in mouse_wheel_events.iter() {
        // this does not compile (transform can't be multiplied by a Vec3):
        transform.translation -= transform * Vec3::ONE * event.y * 1.0; // zoom_sensitivity = 1.0
    }
}

}

Any help would be greatly appreciated.

Thanks,
Greg

The compiler actually tells you whats wrong transform.translation -= transform.translation *... cause transfrom contains translation, rotation and scale
