问题 Suppose I have the following interfaces : public interface GameObject { void viewDetails(); } public interface Weapon extends GameObject { void attack(); } //A weapon is not the only item reloadable. A container could be refilled. public interface Reloadable extends GameObject { void replenish (final int amount); } and Implementation: public final class ReloadableWeapon implements Reloadable, Weapon { private String weaponName; private int numberofbullets; public ReloadableWeapon(String name,

问题 I have a DLL written in C++ that is legacy code and cannot modify the source code. I want to be able to call some of the functions inside of the DLL from Lua. For example, I'd like to do something like this: -- My Lua File include(myCppDll.dll) function callCppFunctionFromDll() local result = myCppFunctionFromDll(arg1, arg2) --Do something with result here end Is something like this possible? 回答1: If Alien doesn't meet your needs, and it might not be easy to use if the DLL has a strongly
