|

* apply dynamics, collision solving and position correction. It uses a very simple struct for physic
|
||||
* bodies with a position vector to be used in any 3D rendering API.

|
|||
* If not defined, the library is in header only mode and can be included in other headers
|
||||
* or source files without problems. But only ONE file should hold the implementation.
|
||||
*
|
||||
* #define PHYSAC_DEBUG
|
||||
* Show debug traces log messages about physic bodies creation/destruction, physic system errors,
|
||||
* some calculations results and NULL reference exceptions.
|
||||
* #define PHYSAC_STATIC (defined by default)
|
||||
* The generated implementation will stay private inside implementation file and all
|
||||
* internal symbols and functions will only be visible inside that file.
|
||||
*
|
||||
* #define PHYSAC_AVOID_TIMMING_SYSTEM
|
||||
* Disables internal timming system, used by UpdatePhysics() to launch timmed physic steps,
|
||||
* it allows just running UpdatePhysics() automatically on a separate thread at a desired time step.
|
||||
* In case physics steps update needs to be controlled by user with a custom timming mechanism,
|
||||
* just define this flag and the internal timming mechanism will be avoided, in that case,
|
||||
* timming libraries are neither required by the module.
|
||||
* #define PHYSAC_NO_THREADS
|
||||
* The generated implementation won't include pthread library and user must create a secondary thread to call PhysicsThread().
|
||||
* It is so important that the thread where PhysicsThread() is called must not have v-sync or any other CPU limitation.
|
||||
*
|
||||
* #define PHYSAC_STANDALONE
|
||||
* Avoid raylib.h header inclusion in this file. Data types defined on raylib are defined
|
||||
* internally in the library and input management and drawing functions must be provided by
|
||||
* the user (check library implementation for further details).
|
||||
*
|
||||
* #define PHYSAC_DEBUG
|
||||
* Traces log messages when creating and destroying physics bodies and detects errors in physics
|
||||
* calculations and reference exceptions; it is useful for debug purposes
|
||||
*
|
||||
* #define PHYSAC_MALLOC()
|
||||
* #define PHYSAC_CALLOC()
|
||||
* #define PHYSAC_FREE()
|
||||
* You can define your own malloc/free implementation replacing stdlib.h malloc()/free() functions.
|
||||
* Otherwise it will include stdlib.h and use the C standard library malloc()/free() function.
|
||||
*
|
||||
* COMPILATION:
|
||||
*
|
||||
* Use the following code to compile with GCC:
|
||||
* gcc -o $(NAME_PART).exe $(FILE_NAME) -s -static -lraylib -lopengl32 -lgdi32 -lwinmm -std=c99
|
||||
* NOTE 1: Physac requires multi-threading, when InitPhysics() a second thread is created to manage physics calculations.
|
||||
* NOTE 2: Physac requires static C library linkage to avoid dependency on MinGW DLL (-static -lpthread)
|
||||
*
|
||||
* VERSIONS HISTORY:
|
||||
* 1.1 (20-Jan-2021) @raysan5: Library general revision
|
||||
* Removed threading system (up to the user)
|
||||
* Support MSVC C++ compilation using CLITERAL()
|
||||
* Review DEBUG mechanism for TRACELOG() and all TRACELOG() messages
|
||||
* Review internal variables/functions naming for consistency
|
||||
* Allow option to avoid internal timming system, to allow app manage the steps
|
||||
* 1.0 (12-Jun-2017) First release of the library
|
||||
* Use the following code to compile:
|
||||
* gcc -o $(NAME_PART).exe $(FILE_NAME) -s -static -lraylib -lpthread -lopengl32 -lgdi32 -lwinmm -std=c99
