This pack changes how Soulslike Weaponry guns swing in melee through Better Combat. It cuts the upswing to 0.1 seconds, which is 2 in-game ticks. Run this quick test to confirm it is working.
Confirm the data pack is enabled
1. Load the world where you want the faster gun swings. Data packs are tied to a world.
2. Open chat and run /datapack list. This is a vanilla command and needs cheats or operator permission.
3. Look for the pack in the list of enabled packs. If it only appears under available packs, enable it with the vanilla /datapack enable command and the pack's listed name.
4. Make sure Better Combat and Soulslike Weaponry are both loaded. The pack only changes how Better Combat handles these guns, so it does nothing without them.
Test the swing in-game
1. Hold the Hunter Pistol, the Hunter Blunderbuss or the Gatling Gun.
2. Find a passive mob or a training target and hit it up close with your normal attack.
3. Watch the start of the swing. With the pack active, the gun comes up almost instantly before the hit lands, instead of a slow wind-up.
4. Repeat with each of the three guns. All of them should have the fast upswing.
If the swing looks unchanged, run /reload or rejoin the world, then test again.
