How do I protect a Lua script?
Encrypting your compiled Lua files: After compiling all of your Lua files using luac, you can also encrypt them. You must then hide your encryption key somewhere. The easiest approach is simply to hide the key in your app, but it’s also the most vulnerable.
How do I run a Lua script in Redis?
The EVAL command is what tells Redis to run the script which follows. The ”redis. call(‘set’, KEYS[1], ARGV[1])” string is our script which is functionally identical to the Redis’s set command….Three parameters follow the script text:
- The number of provided keys.
- Key name.
- First argument.
Does Redis use Lua?
Redis uses the same Lua interpreter to run all the commands. Also Redis guarantees that a script is executed in an atomic way: no other script or Redis command will be executed while a script is being executed.
Is Lua allowed on iOS?
Apple Allows Lua Scripts to be Downloaded and Run – iOS – Solar2D Game Engine.
What is Lua time limit?
The ‘lua-time-limit’ Value The default value is 5 seconds. This is a really long time for CPU-bound activity (scripts have limited access and can’t run commands that access the disk). However, the script is not killed when it executes beyond this time.
Are Redis operations atomic?
All the commands in a transaction are serialized and executed sequentially. This guarantees that the commands are executed as a single isolated operation. Either all of the commands or none are processed, so a Redis transaction is also atomic.
Can you make an app with Lua?
Yes, you can use only lua to write apps for android using LuaJava from the kepler project (though I don’t believe its being maintained anymore). You can create and manipulate Java objects seemlessly, and interact with the Android APIs through lua. You can even create UI elements dynamically using just lua.
What is Pcall?
pcall stands for “protected call”. It is used to add error handling to functions. pcall works similar as try-catch in other languages. If an error inside a function called with pcall occurs an error is thrown and the rest of the code continues execution.
How to remove or recreate an entity in Lua?
If you want to remove and recreate some entity, you’ll just have to notify the main Lua handle which will be stored inside some global Lua table. And because all your handles in Lua will be references to original handle you won’t have to care about them: once you update the main handle, it’s updated everywhere.
Is it safe to set raw reference to entity in Lua?
And because all your handles in Lua will be references to original handle you won’t have to care about them: once you update the main handle, it’s updated everywhere. Another good thing is that once the entity is removed, we can just set isValid to false and raw reference to nil just to be extra safe.
Can a C + + function be called from Lua?
Once the C++ function is called from Lua, it’s hard to properly throw and catch an error from C++. You’ll have to compile Lua as C++ to do it without a crash. Throwing the error before calling C++ allows us to safely catch it on Lua side and handle it appropriately.
