Cameras

This page is in progress and may contain incomplete information or editor's notes.

The Galaxy games use cameras to create a good view of the game's 3D scene. There are many different types to fulfill this purpose, all of which are detailed on this page. Each stage (galaxies, zones, ...) comes with a file that specifies all the camera setups to be used. The format of these files is specified below.

Contexts

Cameras are used in a lot of different contexts and may be triggered through various means, including:

• Camera areas (CameraArea, CubeCameraBox, etc.) once they are entered. More information below.
• Spawn points (Mario entries in a zone's StartInfo file) once the player respawns there. More information below.
• Warp Pipes once they are entered or left.
• When the player rides Launch Stars or Sling Stars.
• When the player swims underwater or on the water's surface.
• When the player uses the Flying Power-Up.
• While talking to an NPC.
• Various objects and enemies use special cameras, such as SimpleDemoExecutor, JumpBeamer, Poihana and BegomanSpring.
• Cutscenes use various cameras to change the view.

BCAM Format

All camera parameters for a zone (and some objects) are stored in a special BCSV file called CameraParam.bcam. For zones, the file is located in Stage/camera of a Map archive. Not all files will contain all known camera fields in order to save some space. These optional fields are only added when necessary. The following table lists all fields, their default values, data type and whether they are always present or not.

Camera ID Names

The id field of a camera parameter entry is a special ID name that specifies the camera's usage context. Every entry should have a unique ID name. The camera ID is categorized into five different categories which are described below.

Cube

Cube cameras are cameras which are referenced from a camera area (CameraArea in Super Mario Galaxy 2, CubeCamera, CubeCameraBox etc in Super Mario Galaxy). When the player is inside a camera area, it activate the referenced camera. If multiple camera areas interesect, the area with the highest priority (Obj_arg2) will be selected. The camera area's Obj_arg0 value specifies the ID number of the camera to be used. Using this value, the game generates an identifier string using the printf format string c:%04x. For example, if your camera area has an Obj_arg0 of 15, the corresponding camera ID name would be c:000f. Note that the hexadecimal digits must be lowercase.

Start

Start cameras are used when a camera is referenced from a start point. Every player spawn point (Mario entries in a zone's StartInfo) can activate a camera once the player respawns there. Just like camera areas, the game constructs an identifier string from the spawn point's CameraSetId which will be used to locate the parameters for the camera. The printf format string is s:%04x. For example, if your Mario entry has a CameraSetId of 60, the corresponding camera ID name would be s:003c. The hexadecimal digits must be lowercase. If the CameraSetId is negative, no camera will be used.

Event

Event cameras are cameras which are used for different events. One example of an event camera is Mario's intro flying, which is shown when entering all galaxies. Event cameras have the format "e:S:XXX:YYY" where S is the event name, XXX is the camera set ID in lowercase hex and YY is the event index, also in lowercase hex. Most event consists of multiple cameras, which is what YY is used for. For example, the camera for the second Mario's intro flying, with the camera set ID 5 would be "e:シナリオスターター:005:01番目". The following table shows known event cameras:

ID	Description
e:シナリオスターター:XXX:YY番目	Scenario start camera YY.
e:スーパースピンドライバー:XXX:YY番目	Super spin driver camera YY. Camera 00 is used when Mario enters the launch star, and 01 and up are used for when Mario is flying.
e:スーパースピンドライバー固有出現イベント用XXX	Super spin driver appearance event camera for camera set ID XXX.

Group

Group cameras have unknown usage, but has the format "g:S" where S is the group name.

Other

Other cameras are used for various cameras which does not belong to any of the previously described categories. The ID follows the format "o:S" where S is the name. The following table shows known other cameras:

ID	Description
o:デフォルトカメラ	Default camera to be used if no other camera is active or available.
o:デフォルト水中カメラ	Default camera to be used when the player is swimming underwater.
o:デフォルト水面カメラ	Default camera to be used when the player is swimming on water surface.
o:デフォルトフーファイターカメラ	Camera to be used when the player is using the Flying Power-Up.
o:ズームカメラ	The first person's view camera.

Camera Classes

There are many fine-tuned camera classes to choose from. The camtype field of a camera entry specifies what class to use. The available classes in the Galaxy games are:

Aliases

Likely for the purpose of preserving compatibility with test camera files, the developers added aliases for some camera classes. These exist in both Galaxy games. However, these aliases only apply if the camera version is greater or equal to the required version. Interestingly, it also contains an alias for CAM_TYPE_BOSS_DONKETSU, a camera class that has been removed from the actual game.

Alias Name	Actual Name	Required Version
CAM_TYPE_DONKETSU_TEST	CAM_TYPE_BOSS_DONKETSU	196612
CAM_TYPE_BEHIND_DEBUG	CAM_TYPE_SLIDER	196614
CAM_TYPE_INWARD_TOWER_TEST	CAM_TYPE_INWARD_TOWER	196614
CAM_TYPE_EYE_FIXED_THERE_TEST	CAM_TYPE_EYEPOS_FIX_THERE	196614

Trivia

• The oldest available camera version is 196617 and can be found in HellLavaFloatingZone.
• The function CameraParamChunk::load references a removed camera class labeled as CAM_TYPE_PLANET.
• Intro cameras dynamically create a CAM_TYPE_ANIM camera with the ID o:スタートアニメカメラ. It is not possible to overwrite this in a BCAM file.
