What does the MSW Guns' Upswing Data Pack actually do?
It gives the Soulslike Weaponry guns custom Better Combat melee animations and cuts their upswing time to 0.1 seconds. When you hit something up close with the Hunter Pistol, Hunter Blunderbuss, or Gatling Gun, the swing comes out much faster.
Do I need Better Combat for this to work?
Yes. The pack works through Better Combat's melee swing system, so without Better Combat (and Soulslike Weaponry for the guns themselves) it has nothing to apply its animations and timing to.
Which guns get the faster swing?
The Hunter Pistol, the Hunter Blunderbuss, and the Gatling Gun from Soulslike Weaponry. All three use the same fast 0.1-second upswing when you melee with them.
What does 'upswing 0.1 seconds' mean in game?
Upswing is the wind-up part of a Better Combat attack, before your hit actually lands. At 0.1 seconds (2 in-game ticks), the gun connects almost as soon as you press attack, so you can strike mobs that get too close without a long wind-up.
Does this change how my guns shoot or how much damage they do?
No. The pack only affects the melee swing, meaning the animation and upswing timing when you hit with the gun. Firing is still handled by Soulslike Weaponry as normal.
How do I check the data pack is actually enabled in my world?
Run /datapack list and look for the pack among the enabled packs. Then hold one of the guns and attack a mob up close. The swing should start and land almost instantly, using a Better Combat animation instead of a sluggish default swing.
Can I add this to an existing world or server?
Yes. Put it in that world's datapacks folder (or the server world's), then run /reload or restart. Your existing guns pick up the new swing behavior without needing to be replaced.
Does it go on the client or the server?
The data pack belongs to the world, so on a multiplayer server it goes in the server's world and applies to everyone. Better Combat and Soulslike Weaponry still need to be installed wherever those mods require, which normally means both client and server.
Will this data pack hurt performance?
No. It only contains data files that tell Better Combat how the guns swing, with no new blocks, entities, or world generation, so it has no meaningful performance cost.
