CS:GO Keyframe Smoothing Script
Quick smooth camera path creation.
Installation
Merge the /csgo/ folder with your /steamapps/common/Counter-Strike Global Offensive/csgo/ folder.
This only adds 8 files to your /csgo/ folder. It does not overwrite any game files, and it does not interfere with the game in any way. You can only use this script on your own server.
Downloading
Method 1.
Manually download the repository (Code > Download ZIP), then extract the folder.
Method 2.
On Windows 10 17063 or later, run the install_keyframes.bat file to automatically download the script into your game files. It can also be used to update the script.
Method 3. In bash, after changing the directory below to your Steam game library directory, use the following commands to install the script into your game files.
cd "C:/Program Files/Steam/steamapps/common/Counter-Strike Global Offensive/" &&
curl https://codeload.github.com/samisalreadytaken/keyframes/tar.gz/master | tar -xz --strip=1 keyframes-master/csgo
Usage
Use the console commands to load and control the script. You need to load it each time you change the map.
See the Default Key Binds section below for the keys that are available for you to use by default. These do not modify your settings. Optionally, bind your other keys to improve your workflow. You can find some examples at the bottom of the keyframes.cfg file.
Before uncommenting the key binds in the config file, make sure you have a backup of your own binds that would be modified.

File export
You can open the exported file (.log) with any text editor. You must replace L with blank, i.e. remove, for the data to work.
Once you have cleared the exported file, either copy and paste it all in the keyframes_data.nut file, or rename the file extension to .nut and add it in the data file with IncludeScript("kf_data_00000000.nut").
The data name can only contain letters and numbers, it cannot start with a number. You can store as much data as you want, and load any at any time.
You may reload the files with kf_loadfile, load named data with script kf_load().
You can convert old saved data to new version by loading and saving - script kf_load( my_saved_data ), kf_savekeys/kf_savepath.
Implementation notes
Spline interpolation requires 4 keyframes to interpolate between 2 keyframes. For this reason the very first and the very last keyframes do not have paths leading to and from them, but they affect the interpolation of the keyframes next to them. If desired, kf_auto_fill_boundaries can be used to toggle automatic duplication of these boundary keyframes.
FOV values are interpolated between two consecutive FOV keys, independent of the pos-ang keys. The playback starts with FOV set to data on KEY 1. If KEY 1 FOV data is omitted, it is set to 90.
Modifying any keyframe requires compilation before seeing the changes in playback (kf_play) and in export (kf_savepath). kf_preview can be used to playback these changes without compilation.
You may also select a portion of the compiled path with kf_select_path to playback while fine tuning your path. Use MOUSE1/MOUSE2 to select/cancel the selection. Use kf_play_loop to loop the playback.
kf_transform( int index, Vector offset, Vector rotation ): index is the index of a keyframe to pivot the transform. If index is -1, average position of all keyframes is used as pivot point; if index is -2, current camera position (player) is used as pivot point.
Example: script kf_transform( 2, null, Vector(0, 90, 0) ) rotates all keyframes 90 degrees horizontally (yaw) around keyframe 2.
Example: script kf_transform( 0, Vector(0, 0, 64), null ) moves all keyframes 64 units vertically.
Use the translation manipulator (kf_translate) to easily move keyframes to see their effects on the live updated path.
Hold CTRL (+duck) and MOUSE1 (+attack) to rotate around the current keyframe.
