Fireball Predictor
Players who face ghast fireballs, wither skulls, wind charges or dragon fireballs can use Fireball Predictor to see where each one will land before it hits.
What it does
The mod runs on the client and tracks shots from ghasts, wither skulls, wind charges, dragon fireballs and dispensers, along with shots fired by other players. It works out each projectile's trajectory in real time and shows an arc that ends at the predicted impact point. Prediction reuses vanilla's explosion logic, so the highlighted blocks match the ones that would actually break.
Three overlays make the warning visible: a shockwave dome sized roughly to the coming explosion, block highlights that outline the exact blocks a blast will break, and a warning badge with a countdown when a projectile is on a collision course with the player. Cracking hearts appear over the health bar, showing the damage a hit would leave after armor, Protection, absorption and Resistance are applied. Colors, line widths, domes, HUD anchors and owner filters can be changed in a config screen, which is reached through Mod Menu.
Installation needs Fabric API and YetAnotherConfigLib (YACL) on Fabric, and the mod is published for Fabric and Forge for 1.8.9, 1.21.11, 26.2 and 26.3. The server is optional: only the client needs the mod, and server owners can turn off tracking of shots fired by players for connected clients. The code is under the GNU Lesser General Public License v3.0 only, and the source code and issue tracker are public.
Key features
Trajectory arc
A trajectory arc traces each projectile from the shooter to its predicted impact point, updating in real time.
Shockwave dome
A dome marks the area of the coming explosion, giving a rough size of the blast before it arrives.
Block highlights
Blocks that the blast would destroy are outlined, so the affected area is clear before the explosion.
Warning badge
A badge with a countdown appears when a projectile is on a collision course with the player.
Damage hearts
Cracking hearts over the health bar show the damage a hit would deal once protection and absorption are applied.
