CollisionEvent suggestion

[alexniver]

current CollisonEvent is

pub enum CollisionEvent {
    /// Event occurring when two colliders start colliding
    Started(ColliderHandle, ColliderHandle, CollisionEventFlags),
    /// Event occurring when two colliders stop colliding.
    Stopped(ColliderHandle, ColliderHandle, CollisionEventFlags),
}

I feel hard to use, cause a lot of duplicate code. like:

match e {
Started(handle1, handle2, flags) => {// logic with very little different},
Stopped(handle1, handle2, flags) => {// logic with very little different}
}

maybe this is better

pub enum CollisionType {
    Started,
    Stopped
}
pub struct CollisionEvent {
    handle1:ColliderHandle,
    handle2:ColliderHandle,
    flags: CollisionEventFlags,
    collision_type: CollisionType,
}
