Comparing two approaches for creating floating UI like health bars, text labels, damage numbers, ... using either world space UI or screen space UI.

Both approaches have their pros and cons and can be useful in different situations.

In this video I use Unity and UI Toolkit, but the two approaches for creating floating UI are also relevant in other game engines (Unreal, Godot, self-made, ...)

If you are using Unity and UI Toolkit you might be interested in a Unity Asset Store package that greatly simplifies creating such floating UI. https://assetstore.unity.com/packages/slug/275047
