Crosshair Indicator
Crosshair Indicator is a client-side modification that significantly improves gameplay by changing the crosshair color. When you aim at any mob or player, the regular white crosshair instantly turns red. This allows you to immediately distinguish living targets from the environment.
Important note: the mod only works with Minecraft's default crosshair. If you use a resource pack that changes the crosshair appearance, Crosshair Indicator will still display the classic red crosshair, ignoring any changes from the resource pack.
