Zero Allocation StringBuilder for .NET Core and Unity.
Currently Preview Release, -0.1.0.
Check the releases page, download ZString.Unity.unitypackage.
using Cysharp.Text; // namespace
TextMeshProUGUI text; // TMP_Text
int count = 0;
void Update()
{
text.SetTextFormat("Damage: {0}", count++);
}SetTextFormat is extension method of TMP_Text, there parameter is generics so can avoid boxing, and ZString writes to buffer directly without any ToString allocation. Finally inner buffer copy to TextMeshPro buffer so avoid all string allocations.
