Replay mod documentation

3.1 Movement

3.1.1 Basic Controls

While in the Replay, you can freely move around using the movement keys ( by default).
You can move through block similar to Spectator Mode.

Using the Mouse Wheel, you can modify your flying speed. Scrolling up causes you to fly faster, while scrolling down slows you down.

If you prefer the camera to be controlled similar to vanilla Creative Mode, you can change that in the Replay Settings.

3.1.2 Camera Roll

While in a Replay, you can tilt the Camera.

By default, pressing will tilt the screen clockwise, and pressing will tilt the screen counterclockwise.Using , you can reset the Camera Roll.

When holding the key ( key on Mac) while tilting, you can tilt slower and more precisely.

Hint: Most of the Keybindings mentioned in this documentation can be changed in Minecraft’s Control Menu.

3.1.3 Spectating Entities

You can spectate any living entitiy (including players) while in a Replay. When looking at an entity, a crosshair will be visible.

By right-clicking, you will start spectating the entity. If you want to stop spectating the entity, use your Sneak Key ().

5.4 Compatibility with other Mods

5.4.2 Shaders Mod

Karyonix’ Shaders Mod is no longer compatible with Minecraft Forge starting with 1.9.4. As such it is not compatible with the Replay Mod either.
Please use Optifine instead.

5.4.3 Custom Main Menu

The Custom Main Menu mod is often used in mod packs to customize their Main Menu with a button layout fitting the background image, links to their website / bug tracker and similar.
If you are familiar with it, the button id for the Replay Mod is: 17890234 (text: ).

Due to the nature of this Custom Main Menu mod, buttons added to the Main Menu by 3rd party mods like the Replay Mod will not show up by default.Thus, to access the Replay Viewer/Editor/Center, you need to manually configure the position for those buttons.To do so, you need to modify the Custom Main Menu configuration file.
Usually, you can find it at (if you’re using a mod pack launcher, it normally has its own .minecraft folder).For an explanation of this config file, have a look at Custom Main Menu’s page.

You can find a list of already modified config files here.

5.4.5 LabyMod

LabyMod v3.7.x has been reported to be compatible with ReplayMod and other Forge mods.
Lower versions are not compatible.

5.4.6 OldAnimationsMod

In case your Minecraft crashes when you are using both ReplayMod and OldAnimationsMod, try removing OldAnimationsMod.

5.4.7 Orange’s 1.7 Animations

If you use ReplayMod with shaders and 1.7 Animations you may see floating water and glass. Remove 1.7 Animations to resolve this.

5.4.9 Baritone

The Baritone mod can cause a crash when you’re trying to load a replay. If you experience such problems, try running without Baritone.

5.4.10 RandomPatches

Minecraft may crash if you try to use RandomPatches together with ReplayMod. Try removing RandomPatches if Minecraft crashes on startup.

5.4.11 Sodium

ReplayMod can record when Sodium is installed but will crash during render. Disable Sodium before rendering, it can be re-enabled after that.

5.4.13 LiteLoader

LiteLoader is known to cause issues due to the mixin version it contains.

You can use MultiMC to workaround this problem.

The MultiMC function requires that your computer has a default editor for json files associated.

Building

Make sure your sub-projects are up-to-date:

For compiling 1.7.10, you must run once after the initial clone. This may take quite some time.

No IDE

You can build the mod by running (or just ). You can then find the final jar files in .
You can also build single versions by running (or just ) (builds the MC 1.8 version).

IntelliJ

Ensure you have at least IDEA 2020.1.
Build the mod via Gradle as explained above at least once ( should be sufficient). This will ensure that the sources for all MC versions are generated.
Then import the Gradle project from within IDEA: File -> Open -> build.gradle -> Open as Project
Finally configure IDEA to build everything by itself instead of delegating it to Gradle (cause that is slow): File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle -> Build and run using: IntelliJ IDEA

3.4 Custom Objects

3.4.1 Introduction

Custom Objects are mainly meant for video creators. They allow you to add any image into the Replay World and animate its Position, Opacity and much more.

Instead of using Motion Tracking to add text or pictures to a video, you can directly add these to the
rendered file.

3.4.2 Adding Assets

In order to create Custom Objects, you first have to add Assets to your Replay File.
Therefore, open the Asset Manager using the G key.

In the Asset Manager, you can add Image Files (.png, .jpg and more), so-called Assets, to the Replay.
When clicking the «Add» button, a File Chooser will show up. Select the image file you want to use.
You can give the Asset a custom name using the Text Input Field in the top right corner.

All of the Assets you added can be used by Custom Objects.

The Asset Manager with an example Asset

3.4.3 Creating Custom Objects

Using the F key, you can open the Object Manager. Initially, there won’t be any Objects in the Object List, but you can
simply add an Object using the «Add» button.
After doing so, you can name the newly created Custom Object using the Text Field in the upper right corner.
To define which Asset File (i.e. image) the Custom Object should use, select the desired Asset from the dropdown beneath the Name Input.

If you leave the Object Manager, you should see the image in the World somewhere near your position.

The Object Manager with some Animation Keyframes.

3.4.4 Animating Custom Objects

Of course, you don’t want the image to stay at that position. Therefore, open the Object Manager again and select the Custom Object you want to modify.
On the lower half of the screen, you will see multiple Input Fields, using which you can modify various settings (so-called Transformations), for example the Object’s
Position, Scale, Orientation and Opacity.

When editing these values, you’ll notice that on the Timeline to the right, Keyframes appear.
You can set and remove Keyframes for specific settings using its «Add Keyframe» button on the very left of the screen.

The Object Manager’s Keyframe System is very similar to the Position Keyframe and Time Keyframe System.

During a Camera Path, the Custom Objects will interpolate their Transformation Values like Position Keyframes are interpolated.
While outside the Object Manager, you can preview the Objects’ position by moving the cursor on the Keyframe Timeline — the Objects will
interpolate to the position they’ll be at that timestamp during the Camera Path.

Once you got the hang of it, you’ll be able to quickly animate Custom Objects.

Development

Branches

TL;DR:
Main development happens on the branch, snapshots are built from this branch.
The branch contains the most recent release.

The branch is solely to be used for the file that contains a list of all versions
used by the clients to check for updates of this mod.

The Preprocessor

To support multiple Minecraft versions with the ReplayMod, a JCP-inspired preprocessor is used:

        //#if MC>=11200
        // This is the block for MC >= 1.12.0
        category.addDetail(name, callable::call);
        //#else
        //$$ // This is the block for MC < 1.12.0
        //$$ category.setDetail(name, callable::call);
        //#endif

Any comments starting with will automatically be introduced / removed based on the surrounding condition(s).
Normal comments are left untouched. The branch is optional.

Conditions can be nested arbitrarily but their indention shall always be equal to the indention of the code at the line.
The shall be aligned with the inner-most .

    //#if MC>=10904
    public CPacketResourcePackStatus makeStatusPacket(String hash, Action action) {
        //#if MC>=11002
        return new CPacketResourcePackStatus(action);
        //#else
        //$$ return new CPacketResourcePackStatus(hash, action);
        //#endif
    }
    //#else
    //$$ public C19PacketResourcePackStatus makeStatusPacket(String hash, Action action) {
    //$$     return new C19PacketResourcePackStatus(hash, action);
    //$$ }
    //#endif

Code for the more recent MC version shall be placed in the first branch of the if-else-construct.
Version-dependent import statements shall be placed separately from and after all other imports.
Common version dependent code (including the fml and forge event bus) are available as static methods/fields in the class.

The source code in is generally for the most recent Minecraft version and is automatically passed through the
preprocessor when any of the other versions are built (gradle projects , , etc.).
Do NOT edit any of the code in as it is automatically generated and will be overwritten without warning.

You can change the version of the code in if you wish to develop/debug with another version of Minecraft:

./gradle :1.9.4:setCoreVersion # switches all sources in src/main to 1.9.4

If you do so, you’ll also have to refresh the project in your IDE.

Make sure to switch back to the most recent branch before committing!
Care should also be taken that switching to a different branch and back doesn’t introduce any uncommitted changes (e.g. due to different indention, especially in case of nested conditions).

Some files may use the same preprocessor with different keywords.
If required, more file extensions and keywords can be added in the block of the script.

Versioning

• No , the ReplayMod does not provide any external API
• «Updating to a new Minecraft version» should not increment , we maintain one version of the ReplayMod
  for each version of Minecraft and all these versions share the same feature set (and most bugs). We therefore try to
  keep the version name the same for all of them (with the exception of of course). This also means that the
  «Multiple Minecraft Version» section does not apply.
• For pre-releases the shorter is used instead of

When a new version is (pre-)release, a new commit modifying the file should be added and the
file in the branch should be updated. To simplify this process the gradle task can
be used: . It will create the commit and update the version.json
accordingly.

Care should be taken that the updated is not pushed before a jar file is available on the
download page (or Jenkins) as it will inform the users of the update.

1.3 Compatibility with other Mods

1.3.1 General information

In General, the Replay Mod should be compatible with most Forge Mods. However, due to the way that recording works, many Mods that add new Blocks, Mobs or Game Mechanics are not supported.
Mods that simply modify the Client (like the PixelCam Mod or the
CommandGroups Mod) usually work.

1.3.2 Optifine

The Replay Mod is compatible with , which can be downloaded at http://optifine.net/downloads.
Other Optifine Versions for Minecraft 1.8.0 might, but don’t have to be compatible as well.

Warning: If you have Optifine installed, you can not render videos from within the Replay Mod.
This might change in future Replay Mod versions.

1.3.3 Shaders Mod

You can use the Replay Mod together with karyonix’ Shaders Mod,
but rendering videos results in possible crashes and malformed videos. Therefore, you have to uninstall the Shaders Mod before rendering.

1.2 Installing FFmpeg

To render your creations with Replay Mod you will need to have FFmpeg installed.

1.2.1 Windows

Download the latest FFmpeg release from https://www.gyan.dev/ffmpeg/builds/ffmpeg-release-essentials.zip.

Extract the downloaded .zip file into your folder.

Historically the exact location inside the folder was important, this is no longer the case.
It is sufficient for the to be anywhere inside your folder.

Notes for alternative launchers

• Twitch launcher by default installs Minecraft instances in C:\Users\username\Twitch\Minecraft\Instances\instancename\
• GD Launcher by default installs Minecraft instances in C:\Users\username\AppData\Roaming\gdlauncher_next\instances\instancename\
• MultiMC by default installs Minecraft instances in C:\Program Files (x86)\MultiMC\instances\Instancename\.minecraft\

For these launchers, make sure FFmpeg exists inside the corresponding folder.

1.2.2 Mac OSX

On OSX, you can install FFmpeg with Homebrew using .

Alternatively, you can download the latest static build from https://ffmpeg.org/ and copy the FFmpeg executable to .

1.2.3 Linux

On Linux, you can install FFmpeg using your system’s package manager, for example using .
If in doubt, consult the documentation of your distribution.

Frequently Asked Questions

For how long can I record?

Theoretically, a Replay File can be up to 24 days, 20 hours, 30 minutes and 23 seconds long — which is a timespan you’ll probably never reach.

How many chunks around me does the Mod record?

If you’re playing in Singleplayer, all of the loaded chunks within your Render Distance are recorded.If you’re on a server, this depends on the view-distance setting in the server.properties file, which is set to 11 Chunks by default.

The Replay Mod of course records every loaded, not only the rendered chunks. Therefore, chunks behind your back are recorded as well.

Why can’t I start recording in the middle of a session?

Due to the way the Replay Mod works, you need to start recording when joining a Server or World — otherwise some data which the Replay Files need is missing.

How does recording affect my FPS?

Usually, recording a Replay does not affect your framerate, and it also doesn’t lead to lag on servers.We’ve tested the Mod on a low-end notebook with only 3GB of ram, and everything worked fine.

3.1.1 Basic Controls

While in the Replay, you can freely move around using the movement keys ( by default).
You can move through block similar to Spectator Mode.

Using the Mouse Wheel, you can modify your flying speed. Scrolling up causes you to fly faster, while scrolling down slows you down.

If you prefer the camera to be controlled similar to vanilla Creative Mode, you can change that in the Replay Settings.

3.1.2 Camera Roll

While in a Replay, you can tilt the Camera.

By default, pressing will tilt the screen clockwise, and pressing will tilt the screen counterclockwise.Using , you can reset the Camera Roll.

When holding the key ( key on Mac) while tilting, you can tilt slower and more precisely.

Hint: Most of the Keybindings mentioned in this documentation can be changed in Minecraft’s Control Menu.

3.1.3 Spectating Entities

You can spectate any living entitiy (including players) while in a Replay. When looking at an entity, a crosshair will be visible.

By right-clicking, you will start spectating the entity. If you want to stop spectating the entity, use your Sneak Key ().

5.2 Crash while rendering

If Minecraft crashes after a few frames of rendering, it most likely means the FFmpeg didn’t like the Command Line Arguments you passed.
If you customized the Command Line Arguments manually, re-check them — it’s probably your own fault.

Hint: In your .minecraft folder, you’ll find a file called which contains information about FFmpeg’s rendering process.

• If you did not customize the Command Line Arguments, you might have entered some insanely high (or low) values e.g. for Bitrate or Video Resolution. Try again with other, more reasonable values.
• Make sure the camera doesn’t move below Y=0 or above Y=255
