Constants¶

Control Flags¶

Declared in: add-ons/graphics/GraphicsCard.h

B_CRT_CONTROL
B_GAMMA_CONTROL
B_FRAME_BUFFER_CONTROL

These flags report the driver’s ability to control the CRT display, make gamma corrections, and permit nonstandard configurations of the frame buffer. Only the last has any meaning for the Game Kit.

gs_attributes¶

Declared in: game/GameSoundDefs.h

B_GS_MAIN_GAIN
B_GS_CD_THROUGH_GAIN
B_GS_GAIN
B_GS_PAN
B_GS_SAMPLING_RATE
B_GS_LOOPING
B_GS_FIRST_PRIVATE_ATTRIBUTE
B_GS_FIRST_USER_ATTRIBUTE

These are the various possible game sound attributes. The range between B_GS_FIRST_PRIVATE_ATTRIBUTE and B_GS_FIRST_USER_ATTRIBUTE are reserved; if you need custom attributes, use values B_GS_FIRST_USER_ATTRIBUTE and higher.
