to first get the gold arm, find this frickin' door in 7-1, and carry the blue skull to it:

The timestop ability will start with 3 seconds by default, you can upgrade your arm through this button

and then this menu over here:

Each upgrade increases the time by around one second, changes by the upgrade count though. There can be a maximum of 10 upgrades.

Fix

• Fixed Coins thrown in stopped time can now be punched
• Fixed Timestopper Progress no longer reads and writes from the disk multiple times per frame ( Huge FPS boost )
• Fixed objecs not having correct velocities when going through a portal in timestop
• Fixed AudioMuffleZone not working in stopped time, and sometimes being persistent

• Optimization Grayscaler no longer runs when shaders are off
• HUGE optimization!
  • Many many Update() calls have been changed with manual static array loop calls
  • All FixedUpdate() calls have been centralized and modularized
  • Inverted certain HashSets to Lists where iteration performance matters
  • Got rid of many many expensive per-frame operations
  • Introduced new cached values
• Changed Grayscale shader plane is now almost exactly at near plane distance, hopefully fixing mst of portal visuals when up close

Summary

• Various performance improvements
• New shaders!
• Better HUD integration
• Full audio customization
• DualWield powerup now works as intended!
• JackHammer now works in timestop as intended!

• Fixed Speedometer and other player speed getter related problems
• Fixed Inverted crosshair not working with grayscale shaders

Technical Wrapup

• Added Timestopper Pickup prefab into the assetbundle
• Fixed text disappearance by not using Graphics.Blit()
  • Instead, a very thick cube right in front of the Main Camera is spawned with a transparent grayscale shader
  • A depth camera renders a depth texture for the shader to use, inside a global variable called _MyCustomDepth
  • This shader should be more bug free, since there is no more rendering the HUD twice to maintain color
• BlindCheat is no longer used to prevent visual bugs during timestop, instead a Player dummy is replaced in the PlayerTracker instance
  • This also fixes V2-1st softlock if she was defeated during timestop
• Added the WaitForPlayerSeconds() yieldInstruction
  • Patched JackHammer to change all WaitForSeconds() to WaitForPlayerSeconds()
• Performance inprovements
  • Gibs are no longer simulated when they are completely halt
  • Hud no longer renders twice for the grayscale effect
  • Epensive function calls per frame have been reduced
  • HUD elements operate on custom scripts directly attached to them
  • Active game object tracking instead of per frame search operations
• The arm is now called Time Arm instead of Gold Arm to avoid confusion upon the release of official Golden Arm
• More efficient asset bundle and TimeArm prefab
• Functionality is now inside the arm instance itself rather than looking up variables tied to the Player
• Certain functions were carried to their own classes that make more sense
• got rid of FindRootGameobject()
• added TimeHUD class for Time Juice Bar HUD element

Very Small

• Grayscale amount can now be set to any number

Small

• The arm now displays a messsage of which button to use it when you pick it up
• Menu texts no longer disappear because of the mod in some custom maps
• Music detection is now more accurate and should work in all levels

• More null preventers were added to the save system for timestopper.state

Very small

• Fixed a bug where The Timestopper would disappear when died
• Removed the Under Construction text from the Gold Door in 7 - 1
• Updated the arm description, so the mechanics are more clear
• Updated the graphics in the README.md file

>Grayscale Shaders are not supported in Linux Machines yet!

• Time Juice now resets properly when died or reset to checkpoint
• Time Juice bar now doesn't overlap with the Speedometer
• The Speedometer now updates as intended in stopped time
• Fixed a little bug with Compatability with CyberGrindMusicExplorer

technical changes

• Patched TimeSince to use unscaledDeltaTime when Timestopper.unscaleTimeSince is true. Used in FixeUpdateCaller when calling FixedUpdate manually.
• Time Juice resets now use StatsManager.checkpointRestart
• Speedometer and other HUD elements which overlapped with Time Juice bar are now moved instead of set to position
• More integration with already there Ultrakill classes and structs

The Freezeframe Comeback!

• Added the option to downgrade the arm to the maximum upgrade count
• Added a message to indicate the appearance of a new door in 7-1
• Fixed inconsistent movement in timestop
• Fixed parrying catapulting Player
• Fixed physics speeding up during the timestop sequence

technical changes

• Reworked FixedUpdateCaller system
• Timestop Jump Fix has been reworked, but still doesn't act identically to non-timestop
• Reworked Timestopper.playerTimeScale, Timestopper.playerDeltaTime and Timestopper.playerFixedDeltaTime
• Timestopper.playerDeltaTime and Timestopper.playerFixedDeltaTime are now read only properties instead of fiels

Global Fix

• Fixed a bug where movement was FPS dependent

Little Update

• Fixed a bug where the time juice would still drain in the pause menu
• Fixed a typo in configgy settings, "Interaction Slowdown Multiplier"
• Recalibrated default configgy settings
• Hopefully fixed some Null Reference Exceptions
• Added temporary fixes to configgy menu for a bug where Player slowed down

Emergency QuickFix

• Fixed a bug where the mod didn't work at all

Ultra Bugfix

• Movement in timestop got reworked
• A bug fixed where timestart would catapult Player
• Every gun except the jackhammer works (hopefully) properly now
• Added animation speed multiplier to settings
• Complete (90%) code rework
• Improved performance (probably)

• Jackhammer still doesn't work!

technical changes

• Codebase cleaned, now it is easier to use, for possible use as timestop library
• Timestop is now Action based instead of hard setting timeScale every frame
• Many hardcoded main game modifications are automated, so they won't break with further updates (hopefully)
• Main game patches now change Time.deltaTime with Timestopper.playerDeltaTime instead of Time.unscaledDeltaTime

notes:

Even though you can use this mod as a library to stop and start time, I recommend you to communicate with me before doing so, for convenience sake. I may release a separate library for timestop related functions. Right now, if you include and reference Timestopper in your mod base, you should be able to use Timestopper.StopTime() and Timestopper.StartTime() easily. I don't think I will ever change the function names, but new ones may be added or current ones might be removed.

Cybergrind Fix

• Added compatibility with Cybergrind Music Explorer mod, the HUD doesn't overlap
• Cleaned the code a little bit
• Properly added github repository
• Learned how to properly use SceneManager.SceneLoaded

Quick bugfix
