LVD Level Data (Smash 4)
Overview
LVD is the file type used by both versions of Smash 4 to store various bits of level data. They are used for spawns, respawns, collisions, blast zones, camera bounds, the per-stage locations of various final smash events (such as where Ike's final smash takes Ike and his opponent), and much more. It is even used to store the board paths for Smash Tour.
Structure
LVDs structure is relatively easy to read however it isn't possible to skip unknown data when parsing it due to it being a completely linear file type.
| Offset | Type | Description |
|---|---|---|
| 0x0 | uint32 | Version number (Always 1) |
| 0x4 | byte[6] | Magic ending in "LVD1" |
After the header comes all the entries in the format
| Offset | Type | Description |
|---|---|---|
| 0x0 | byte | Value 0x1, a separator character |
| 0x1 | uint32 | Number of Entries of this type |
| 0x5 | Entry[entryCount] | Entries of this type |
Note that if there is none of a type present that there still must be the separator and count of 0. The list of types in LVD version 1 (in order) is below:
| Type | Type Name | Description |
|---|---|---|
| 1 | Collisions | The actual collisions of the stage |
| 2 | Spawns | Where the players spawn at the beginning of the match (in order by player number) |
| 3 | Respawns | Where the player respawn on a platform when they die |
| 4 | Camera bounds | How far the camera can move vertically and horizontally |
| 5 | Blastzones | How far the player can go before losing a stock |
| 6 | Unknown | No known example |
| 7 | ITEMPT_transform | Used only on Smash Run |
| 8 | Enemy Generator | Used only on Smash Run to spawn enemies |
| 9 | ITEMPT | Used only on Smash Run |
| 10 | fsAreaCam | Used only on Smash Run |
| 11 | fsCamLimit | Used only on Smash Run |
| 12 | Damage Shapes | Damage sphere and Damage capsule are the only subtypes I've seen. (Note: this is a hurtbox such as Luigi's Mansion Pillars |
| 13 | Item Spawners | Lines that items "rain down" from, i.e. items spawn on the nearest collision under it |
| 14 | General shapes | General rectangle, general path, etc. used for Smash Tour pathways and other random stuff |
| 15 | General points | Used for points to be reference by code (such as Ike's final smash position among other things) |
| 16 | Unknown | No known example |
| 17 | FsStartPoint | Used only in Smash Run |
| 18 | Unknown | No known example |
| 19 | Unknown | No known example |
Collisions
Collisions are stored as collision header data, vertices positions and line data. Line data includes how it reacts with physics, the angle you can pass through it, the ledges, etc.
| Name | Type | Description |
|---|---|---|
| Identifier | byte[12] | Always "03 04 01 01 77 35 BB 75 00 00 00 02" |
| Separator | byte | 01 |
| Name | char[0x38] | Null padded string of length 0x38 containing the name (doesn't matter what this is) |
| Separator | byte | 01 |
| Subname | char[0x40] | Null padded string of length 0x40, sometimes used to determine which model the collision is rigged to |
| Separator | byte | 01 |
| Start Position | float[3] | Position to offset the collision by at the start, mainly for matching it to the start of a model's animation |
| Use Start Position | bool (byte sized) | Whether or not to actually use the start position |
| Separator | byte | 01 |
| Unknown | uint32 | Always 0 |
| Separator | byte | 01 |
| Unknown | byte[0xC] | Always 0s |
| Unknown | uint32 | Always 0xFFFFFFFF |
| Separator | byte | 01 |
| Bone to rig to | char[0x40] | Null padded string of length 0x40, sometimes random data other times it is the name of the bone to rig the collision to |
| Unknown | byte | Always 0 I think |
| Rig Collision | bool (byte sized) | Whether or not to rig the collision |
| Unknown | bool (byte sized) | Unknown flag |
| Drop through | bool (byte sized) | Whether or not the player can drop through the collision by hitting down when standing on it |
| Separator | byte | 01 |
| Vertex Count | uint32 | Number of Vertices in the collision |
| Vertices | Vector2[vertexCount] | Vertices Positions |
| Separator | byte | 01 |
| Passthrough Count | uint32 | Number of passthrough angles |
| Passthroughs | Vector2[passthroughCount] | One per line between every 2 neighboring vertices, describes the angle you can pass through the collision as a unit normal vector |
| Separator | byte | 01 |
| Cliff Count | uint32 | Just use this to skip the cliffs, they aren't worth your time |
| CLIFFs | Cliff[cliffCount] | each is 0xFC in length, use that info to skip this stuff because it's most likely debug data as it does not affect gameplay whatsoever |
| Separator | byte | 01 |
| Collision Material Count | uint32 | Number of collision "materials" |
| Collision Materials | CollMaterial[collMatCount] | Collision materials |
Collision Materials
Stores all info about collision lines aside from passthrough angles. (Is it a left ledge, is it a right ledge, is it icy, etc.) is 0xC in size
| Name | Type | Description |
|---|---|---|
| Separator | byte | 01 |
| Unknown | byte[3] | |
| Collision Physics | byte | Determines the type of physics used by the collision (i.e. ice is slippery) |
| Unknown | byte[5] | |
| Flags | byte | Right Ledge = Most significant bit, Left Ledge = 2nd Most significant bit, Don't allow wall jump = 3rd most significant bit |
| Unknown | byte[4] |
