Modules have four associated keywords to make using them in other modules: alias, import, use, and require. alias will register a module under a different (usually shorter) name: defmodule MyModule do # Will make this module available as `CoolFunctions` alias MyOtherModule.CoolFunctions #...

In Java, we can convert between integer values and floating-point values. Also, since every character corresponds to a number in the Unicode encoding, char types can be converted to and from the integer and floating-point types. boolean is the only primitive datatype that cannot be converted to or f...

ScriptableObjects are serialized objects that are not bound to scenes or gameobjects as MonoBehaviours are. To put it one way, they are data and methods bound to asset files inside your project. These ScriptableObject assets can be passed to MonoBehaviours or other ScriptableObjects, where their pub...

You create new ScriptableObject instances through ScriptableObject.CreateInstance<T>() T obj = ScriptableObject.CreateInstance<T>(); Where T extends ScriptableObject. Do not create ScriptableObjects by calling their constructors, ie. new ScriptableObject(). Creating ScriptableO...

Extra care should be taken when accessing serialized fields in a ScriptableObject instance. If a field is marked public or serialized through SerializeField, changing its value is permanent. They do not reset when exiting playmode like MonoBehaviours do. This can be useful at times, but it can also...

Problem Cross-site scripting is the unintended execution of remote code by a web client.
