Easily convert Vec3 to Vec2

[DasLixou]

Hi! im very new to rust but i must say that bevy is very easy to use and understand - i would say i learned the basics of rust just of 2 hours with bevy :D - but i have one problem. Digging in Vec2 there is no implementation of converting from a Vec3 to a Vec2. So half of my code looks like this: Vec3::from((transform.translation.x, transform.translation.y, 0.0)). Is there a simpler way to convert them? thanks :)

Why not use Vec3::truncate to convert from a Vec3 to a Vec2?

The example the code you've given would then use Vec2::extend, i.e. transform.translation.truncate().extend(0.0)

You can import the swizzle methods from bevy::math::swizzles which lets you do some_vec.xy() or .xz() for example to turn it into a vec2
