A script that fixes a lot of things I have personally found to be very annoying.

The config system is now implemented. Please check the EMS folder for 'megapatch.txt'

If the addon *ever* updates, I advise you delete that file and start up a campaign. It will generate an updated config and fix any potential bugs.

Bug fixes

  • Smokers no longer instant grab survivors if they are standing on physics props.
  • Special infected will no longer scratch while staggering
  • Chargers now stagger properly after charging into a wall rather than always staggering towards the world origin
  • Special infected can no longer entirely cancel staggers by falling off ledges
  • Shoving common infected now ensures they get staggered when possible [list]
  • Attempting to stagger a common who is crouching will kill them. This is a partial "fix" for an issue I will continue looking into.

[/list]

Tweaks

  • Charger bots no longer have 66% damage reduction when charging
  • Hunter bots now use z_pounce_damage_interrupt when pouncing
  • Tank rocks now have a marginally smaller radius for hurting players
  • Tank rocks now have a bigger bounding box, allowing them to be shot easier and have more reasonable collisions with the environment
  • Minor adjustments to common infected physics [list]
  • nb_update_frequency is 0.066
  • nb_update_framelimit is 30
  • z_push_force is now 500 to compensate for the increased update frequency and framelimit
