b2Alloc_Default
B2_API void * b2Alloc_Default(int32 size)
Default allocation functions.
b2BodyUserData
You can define this to inject whatever data you want in b2Body.
Definition: b2_settings.h:59
b2Alloc
void * b2Alloc(int32 size)
Implement this function to use your own memory allocator.
Definition: b2_settings.h:100
b2Log_Default
B2_API void b2Log_Default(const char *string, va_list args)
Default logging function.
b2BodyUserData::pointer
uintptr_t pointer
For legacy compatibility.
Definition: b2_settings.h:66
b2Log
void b2Log(const char *string,...)
Implement this to use your own logging.
Definition: b2_settings.h:115
b2JointUserData::pointer
uintptr_t pointer
For legacy compatibility.
Definition: b2_settings.h:90
b2FixtureUserData::pointer
uintptr_t pointer
For legacy compatibility.
Definition: b2_settings.h:78
b2_common.h
b2FixtureUserData
You can define this to inject whatever data you want in b2Fixture.
Definition: b2_settings.h:71
b2Free
void b2Free(void *mem)
If you implement b2Alloc, you should also implement this function.
Definition: b2_settings.h:106
b2JointUserData
You can define this to inject whatever data you want in b2Joint.
Definition: b2_settings.h:83
