ROOM (File Format)
The ROOM format is used to store object layout data in Tropical Freeze.
|
This file format needs more research Still a lot of unknown values and a lot of things that aren't known about how objects interact with each other. |

The remaining data seems to have two structures; one that's used by most objects and one that's specific to GameObject components.
Regular structure:
| Type | Count | Name | Notes |
|---|---|---|---|
| u16 | 1 | Connection Count | |
| Connection | Connection Count | Connection Array | These establish links to other components to allow them to interact |
| u32 | 1 | Property Count | |
| Property | Property Count | Object Properties |
GameObject structure:
| Type | Count | Name | Notes |
|---|---|---|---|
| u32 | 1 | Sub-Component Count | |
| Sub-Component | Sub-Component Count | Sub-Component Array | Seems to describe other script components that are children of this one. |
| bool | 1 | Unknown | This is likely the Active flag that appears on every object in the previous games. |
| vector3 | 1 | Position | |
| vector3 | 1 | Rotation | Euler XYZ angles in degrees (presumably in ZYX order like the previous games). |
| vector3 | 1 | Scale |
Connection
| Type | Count | Name | Notes |
|---|---|---|---|
| char | 4 | Event | This is the event that causes the connection to trigger. (These are what were called States in the previous games.) |
| char | 4 | Action | Action that the connected object should execute when the connection triggers. (These are what were called Messages in the previous games.) |
| GUID | 1 | Target Instance ID | Instance ID of the target object that |
| u32 | 1 | Unknown |
Property
| Type | Count | Name | Notes |
|---|---|---|---|
| u32 | 1 | Property ID | 32-bit hash of the property name. |
| u16 | 1 | Property Size | |
| Property Data | Varies depending on the type of the property (which is hardcoded depending on the property ID). |
Sub-Component
This structure is used to define sub-components that are attached to GameObject components.
| Type | Count | Name | Notes |
|---|---|---|---|
| char | 4 | Type | Usually COMP, but sometimes other things like IL00. Not sure what it means.
|
| GUID | 1 | Component ID | |
| bool | 1 | Unknown | Might be an Active/Enabled flag. |
