| **UFE Netcode** is the second iteration of the network system for UFE. It allows the game to run online matches in a smooth lag-free environment thanks to its native //rollback mechanics// and //deterministic physics//. The netcode also uses raw //manual tracking// to its own core variables, optimizing CPU usage (even mobiles).\\ | **UFE Netcode** is the second iteration of the network system for UFE.

| The new network options also comes with its own client/server structure (using Photon Network, UNet, Steam among others) allowing direct player connection without the use of IP. | The new network options also comes with its own client/server structure (powered by Photon Network) allowing direct player connection without the use of IP. |

| One of the key changes made to the code is the use of ''Fixed Point'' (Fix64), a format that replaces all uses of //float// throughout the code. This update copies all serialized Floats and Vectors to a new similar declaration.\\ | One of the key changes made to the code is the use of ''Fixed Point'' (Fix64), a format that replaces all uses of //float// throughout the code. If you are running UFE 1.x and wish to update your files without having to redo them, use this system to update all serialized Floats and Vectors to a new declaration.\\ |
| To run the auto update, right click on one of your UFE files ([[global:introduction|Global]] , [[character:introduction|Character]] or [[move:introduction|Move]]) from the project tab and select "UFE -> Upgrade to 2.0". This will automatically assign all the new variables (including nested files).\\ | To run the auto update, right click on one of your UFE files ([[global:introduction|Global]] , [[character:introduction|Character]] or [[move:introduction|Move]]) from the project tab and select "UFE 2.0 -> Update All Definitions".

| Now that we have our asset files converted to //Fix64// we can move to the next step to ensure synchronization: Map the character animations. This is a fairly simple process, but can be a bit time consuming depending on how many characters you have or how often you change your animation files.\\ | Now that we have our asset files converted to //Fix64// we can move to the next step to ensure synchronization: Map the character animations.

| To solve this, Map Recorder runs and stores the //position maps// (and delta displacements) of all identified hitbox on every frame of animation throughout the character's moveset, saving them in //Fix64// format (deterministic).
