# Gran Turismo 4 Multiplayer Data

This dataset contains video and action labels of 1v1 races in the PS2 game Gran Turismo 4.

It was used to train the multiplayer world model [Multiverse](https://huggingface.co/Enigma-AI/multiverse).

### Data Structure

The dataset is comprised of more than 4 hours of footage at 30 fps, split into `.hdf5` files containing at most 1000 frames and actions each.

Each frame has a shpae of (48, 64, 6), representing 2 RGB frames stacked together along the channel axis. As can be seen in the following figure:

And the two player action is an array of size (66) in the following structure:

| Player | Range | Control | Meaning |
|:--------|:-------|:---------------|:---------------------------------------------|
| Player 1| 0–10 | Gas | 0 = no gas, 10 = max gas |
| Player 1| 11–21 | Brake | 11 = no brake, 21 = max brake |
| Player 1| 22–32 | Steering | 22 = max left, 27 = straight, 32 = max right |
| Player 2| 33–43 | Gas | 33 = no gas, 43 = max gas |
| Player 2| 44–54 | Brake | 44 = no brake, 54 = max brake |
| Player 2| 55–65 | Steering | 55 = max left, 60 = straight, 65 = max right |

# 《跑车浪漫旅4》（Gran Turismo 4）多人对战数据集

本数据集收录了PS2平台游戏《跑车浪漫旅4》（Gran Turismo 4）中1v1对战赛事的视频与动作标注数据。

该数据集曾用于训练多人对战世界模型[Multiverse](https://huggingface.co/Enigma-AI/multiverse)。

### 数据结构

本数据集包含总时长超4小时、帧率为30fps的赛事录像，按单文件最多包含1000帧与对应动作数据的规则，拆分存储为`.hdf5`格式文件。

每帧数据的形状为(48, 64, 6)，代表沿通道轴堆叠的2帧RGB图像。如下示意图所示：

两名玩家的动作数据为尺寸(66)的数组，其结构如下表所示：

| 玩家 | 取值范围 | 控制项 | 含义说明 |
|:-----|:---------|:---------|:-------------------------------------------------------------|
| 玩家1 | 0–10 | 油门 | 0 = 无油门，10 = 全油门 |
| 玩家1 | 11–21 | 刹车 | 11 = 无刹车，21 = 全力刹车 |
| 玩家1 | 22–32 | 转向 | 22 = 最大左打方向，27 = 直行，32 = 最大右打方向 |
| 玩家2 | 33–43 | 油门 | 33 = 无油门，43 = 全油门 |
| 玩家2 | 44–54 | 刹车 | 44 = 无刹车，54 = 全力刹车 |
| 玩家2 | 55–65 | 转向 | 55 = 最大左打方向，60 = 直行，65 = 最大右打方向 |
