Old Market Simulator · Third Person Camera Mod (ThirdPersonMod)

A third-person perspective Mod made for "Old Market Simulator", a PUBG-style over-the-shoulder perspective, and the B key can switch back to the first-person perspective at any time.

Features

• B key switches between first person/third person, and there is no jump in the perspective when switching.
• Offset viewing angle: the character is located at the bottom right of the screen, adjustable
• Zero parallax of the crosshair: the rays used for picking up and interacting in the third person view are strictly consistent with the crosshair (convergent aiming)
• Automatic eye height calibration: based on the first-person camera position, adapted to different character models
• Character body display: local players are hidden by the game by default (ShadowsOnly only projects but does not render), and automatically restores display in third-person mode
• Camera anti-wall penetration: automatically zooms in when your back is against a wall
• BepInEx configuration file parameter adjustment, changing values ​​without recompiling

Prerequisites

• BepInEx 5.4.x (already installed, just have the BepInEx folder in the game root directory)

Install

• Download ThirdPersonMod.dll from Releases
• Place it in the BepInEx\plugins\ folder of the game directory

| Configuration items | Default value | Description |

|---|---|---|

| Mouse sensitivity | 0.12 | Turn speed per pixel |

| Camera distance | 2.2 | Distance between camera and character (meters) |

| Horizontal offset | -0.35 | The more negative the character is, the closer to the right side of the screen (PUBG is about -0.4 ~ -0.5) |

UnityEngine.AnimationModule.dll

Unity.InputSystem.dll

Implementation principles (for learning)

• Harmony patch ExampleCharacterCamera.UpdateWithInput(KinematicCharacterController), overwrites the camera pose after the original camera logic is executed
• PlayerInteraction.InteractionRay temporarily aligns the camera with the "converging line of sight" at the moment of execution to make the pickup ray consistent with the crosshair, and restores it after completion.
• RenderPipelineManager.beginCameraRendering returns the ShadowCastingMode of the local player renderer from ShadowsOnly to On at the time of RenderPipelineManager.beginCameraRendering
