• Integate bullet into the project

bug when compiling with MinGW: See bulletphysics/bullet3#289
Add following lines to the top of LinearMath/btQuickprof.cpp:

#if WINVER < 0x0600
ULONGLONG GetTickCount64() {return GetTickCount();}
#endif

[Fidge123]

i had problems adding your code, shouldnt it be like this?

#ifdef WINVER < 0x0600

[adi64]

nope, that would check if WINVER is set at all, which is always the case when compiling in a Windows environment.
If it still doesn't work, just add the definition without the #if and #endif :)

[Fidge123]

nevermind, i just had put this at the literal top of the file. It has to be under the includes obviously.

Maybe trains simulation (as a normal rigidBody) can be implemented as invisible wheels adjusted independently.

In order to remove projectiles (or other nodes), we need to provide a thread-safe facility. See #59.
