Im making a sword that swings down if you right click and I need to select what entities take damage how would I make it so all entities take damage in a arcgoing from above your head to the ground in front of you with 1 block width and around 5 block height at its peak and 5 block length at its longest. I can get down the animation and stuff but I still need help figuring out how to select which entities take damage

I think this should work:

ServerPlayer player = ...;

double radius = 8;

List<LivingEntity> list = player.level().getEntitiesOfClass(LivingEntity.class, player.getBoundingBox().inflate(radius,radius,radius), e->(/*filter entities and return true if accetted*/true));
