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