Mod's name is changed to "Double Time! (Tac-Sprint and More) [+TaCZ]"

New trinkets

Kinetic Feedback Insoles — shoot, reload and melee while sprinting. Firing still cancels the tactical sprint, but the ordinary sprint underneath it keeps going, so the shot goes through on the move. Also removes vanilla's movement penalty while using an item, so charging a bow, eating, raising a shield and using a spyglass no longer drop you to a fifth of walking pace.

Omni-Angular Insoles — sprint and tactical sprint in any direction. Vanilla only allows a sprint to start or continue while pushing forward; this measures the whole stick instead, so strafing and backing away count for as much as running forward. Speed is unchanged.

Specialized Ramming Insoles — a tactical sprint bashes doors open. Works on any 1×2 door, including iron, modded and locked ones, because it sets the door's open state rather than pretending to click it. Doors above and below you are left alone. Comes with a kick animation.

Changed

• Tactical sprint entry is faster: 300 ms to reach the carry, was 660 ms.
• The weapon's stride is no longer symmetric. It drops harder than it rises.
• The weapon now trails the camera when you turn and settles back, instead of being welded to it.
• Improved shooting while running accuracy.
• Bolt and pump actions no longer run during a tactical sprint. A bolt will not start while one is running and is tried again when it ends, and a tactical sprint will not start while a bolt is already running. The bolt always has to complete before the weapon will fire; the sprint is not a way to skip it.
• Insoles no longer require boots to equip. They are still ineffective without boots equipped, but now the insole sits in its slot with no effect until you put boots on.

Fixed

• Insoles were thrown back into your inventory on relog.
• A field of view jolt at the end of every tactical sprint without a gun in hand. The widening was being applied as a fixed value rather than a minimum, so at higher speeds it narrowed the view instead of widening it, then crossed back over as the sprint ended.
• Shooting while sprinting fired nothing. The client played the muzzle flash, sound and recoil while the server refused to create the bullet, so no shot landed and no bullet holes appeared.
• The weapon kept its lowered sprint pose while firing on the move.
