About this project
What does Fix Attack Lag add?
When a player uses a ordinary attack to attack a creature, if the attack damage is too large ,it will generate a lot of particles and cause lag(depending on performance, the author's device is around 10 million), even if the particle effect is turned off, it will still cause this lag.
This mod uses the mixin player class attack method to prevent this lag.
