hgdn_property_constant

#define hgdn_property_constant

(

value

)

((const godot_property_get_func){ &hgdn_property_constant_get, (void *) hgdn_property_constant_alloc(hgdn_new_variant((value))), &hgdn_property_constant_free })

Note

In C++ and C11 the value passed is transformed by hgdn_new_variant, so primitive C data can be passed directly
