SaCameraMod

Advanced camera control mod for Minecraft 1.16.5 Forge.

SaCameraMod adds cinematic camera controls with shake, smooth movement, rotation, path interpolation, and perspective switching through /sacamera commands.

Features

Camera Shake — positional or rotational shake with adjustable strength and duration.
Smooth Movement — world-axis movement, yaw-relative movement, and forward-camera directional movement with fade-in, hold, and fade-out transitions.
Rotation — rotate around X, Y, or Z axis, including roll on the Z axis.
Cinematic Keyframes — define multi-keyframe camera paths with interpolation and easing (linear, easein, easeout, easeinout).
Perspective Toggle — force first-person, third-person back, or third-person front view.
Cancel — stop all active effects and restore the default camera.

Commands

Base syntax:

/sacamera <target> <subcommand> [args...]

<target> can be a player selector like @s, @a, or a player name.

Subcommand	Description
`shake positioned <strength> <duration>`	Positional shake
`shake rotationed <strength> <duration>`	Rotational shake
`move <dx> <dy> <dz> <fadeIn> <hold> <fadeOut>`	Move in world coordinates
`move relative <dx> <dy> <dz> <fadeIn> <hold> <fadeOut>`	Move relative to player yaw
`move forward <dx> <dy> <dz> <fadeIn> <hold> <fadeOut>`	Move along camera forward direction
`rotate <axis> <angle> <fadeIn> <hold> <fadeOut>`	Absolute rotation (axis = x/y/z)
`rotate relative <axis> <angle> <fadeIn> <hold> <fadeOut>`	Relative rotation
`cinema <duration> <keyframeList>`	Play cinematic keyframe path
`toggleperspective <mode>`	Switch camera mode: `0`=first-person, `1`=third-person back, `2`=third-person front
`cancel`	Cancel all active camera effects

Cinema Keyframe Syntax

Use semicolons (;) to separate keyframes.

Simple keyframe: x,y,z,yaw,pitch[,ease]
World absolute keyframe: world:x,y,z,targetX,targetY,targetZ[,ease]

Example easing options:

linear — no easing
easein
easeout
easeinout

Examples

/sacamera @s shake positioned 0.5 20
/sacamera @s move forward 0 0 1 0 40 10
/sacamera @s rotate relative y 45 10 40 10
/sacamera @s cinema 100 1,4,1,45,-10;5,5,5,50,-5
/sacamera @s cinema 100 world:1,5,1,0,4,0,easein;world:10,8,10,0,4,0,easeinout
/sacamera @s toggleperspective 1
/sacamera @s cancel

Notes

Commands require operator permission (OP) on multiplayer servers.
The camera control is sent from the server to each target client.
In integrated single-player, the server still sends control packets to the client.
The mod does not force-load unloaded chunks. Camera effects entering unloaded chunks may not render correctly.

中文说明

功能

摄像机抖动 — 支持位置抖动和角度抖动，可调节强度和持续时间。
平滑移动 — 支持世界坐标移动、相对玩家朝向移动、以及沿摄像机前方方向移动，提供淡入、保持、淡出过渡。
旋转 — 支持绕 X、Y、Z 轴旋转，Z 轴代表横滚（roll）。
关键帧运镜 — 支持多个关键帧路径，自动插值并支持缓动（linear、easein、easeout、easeinout）。
视角切换 — 强制切换第一人称、第三人称背后、第三人称正面视角。
取消 — 停止当前所有效果并恢复默认摄像机视角。

指令格式

/sacamera <target> <subcommand> [args...]

<target> 可使用选择器 @s、@a，或直接填写玩家名称。

子命令	说明
`shake positioned <strength> <duration>`	位置抖动
`shake rotationed <strength> <duration>`	角度抖动
`move <dx> <dy> <dz> <fadeIn> <hold> <fadeOut>`	世界坐标移动
`move relative <dx> <dy> <dz> <fadeIn> <hold> <fadeOut>`	相对玩家朝向移动
`move forward <dx> <dy> <dz> <fadeIn> <hold> <fadeOut>`	沿摄像机前方向移动
`rotate <axis> <angle> <fadeIn> <hold> <fadeOut>`	绝对旋转（轴 x/y/z）
`rotate relative <axis> <angle> <fadeIn> <hold> <fadeOut>`	相对旋转
`cinema <duration> <keyframeList>`	播放关键帧运镜路径
`toggleperspective <mode>`	切换视角：`0`=第一人称，`1`=第三人称背后，`2`=第三人称正面
`cancel`	取消所有摄像机效果

关键帧语法

使用分号 ; 分隔关键帧。

简单关键帧：x,y,z,yaw,pitch[,ease]
世界绝对关键帧：world:x,y,z,targetX,targetY,targetZ[,ease]

缓动选项：

linear — 线性
easein
easeout
easeinout

示例

/sacamera @s shake positioned 0.5 20
/sacamera @s move forward 0 0 1 0 40 10
/sacamera @s rotate relative y 45 10 40 10
/sacamera @s cinema 100 1,4,1,45,-10;5,5,5,50,-5
/sacamera @s cinema 100 world:1,5,1,0,4,0,easein;world:10,8,10,0,4,0,easeinout
/sacamera @s toggleperspective 1
/sacamera @s cancel

注意事项

多人服务器中执行指令需要 OP 权限。
指令会由服务器发送控制包到目标客户端。
在单人模式中，服务端仍会向客户端发送控制包。
本 mod 不会强制加载未生成区块，进入未加载区块时画面可能无法正确渲染。

Installation

Place the built mod JAR into your Minecraft mods folder.
Run Forge 1.16.5 with the corresponding Forge version.
