Example #1

File: mathtypes.cpp Project: 0302zq/libgdx

void Matrix4_to_btTransform(JNIEnv * const &jenv, btTransform &target, jobject &source)
{
	matrix4_ensurefields(jenv, source);
	
	jfloatArray valArray = (jfloatArray) jenv->GetObjectField(source, matrix4_val);
	jfloat * elements = jenv->GetFloatArrayElements(valArray, NULL);
	
	target.setFromOpenGLMatrix(elements);
	
	jenv->ReleaseFloatArrayElements(valArray, elements, JNI_ABORT);
	jenv->DeleteLocalRef(valArray);
}

Example #2

{
	matrix4_ensurefields(jenv, target);
	
	jfloatArray valArray = (jfloatArray) jenv->GetObjectField(target, matrix4_val);
