Tags tell you what something is, and they don't break.
The problem
Names break.
if ( other.Name == "Player" ) TakeDamage(); // someone renames it "Player (1)"
Duplicate the object, rename it for clarity, and every check silently stops matching.
The fix
Label what it is.
A tag is a label on a GameObject. Any object can have several, and names can change freely.
GameObject+"player"+"enemy"
The fix in code
Add it, then check it.
// when the player spawnsGameObject.Tags.Add( "player" ); // anywhere elseif ( other.Tags.Has( "player" ) ) TakeDamage();
Tags.Add labels an object. Tags.Has checks for the label, whatever the object is called.
Bonus
Traces understand tags.
var tr = Scene.Trace.Ray( start, end ) .WithoutTags( "player", "trigger" ) .Run();
Skip whole categories of objects in a trace with one call.
The rule
Ask what it is, not what it's called.
- Label it
- Tags.Add( "player" )
- Check it
- Tags.Has( "player" )
- Skip in traces
- WithoutTags( ... )
