子弹.pxd:
cdef extern from "bullet/LinearMath/btVector3.h":
cdef cppclass btVector3:
btVector3(float, float, float) except +
btVector3 operator+(const btVector3&, const btVector3&)
btmath.pyx:
cimport bullet as bt
cdef class Vector:
cdef bt.btVector3* _this
def __cinit__(self, float x=0, float y=0, float z=0):
self._this = new bt.btVector3(x, y, z)
def __add__(Vector self, Vector other):
vec = Vector()
del vec._this
vec._this[0] = self._this[0] + other._this[0]
return vec
btVector3.h中operator+的原型:
SIMD_FORCE_INLINE btVector3
operator+(const btVector3& v1, const btVector3& v2);
如标题中所述,我得到“'+' (btVector3; btVector3) 的操作数类型无效”。我猜这可能与 Cython 如何处理引用传递有关,也许?
任何帮助将不胜感激。
