![]() ![]() We released Godot 3.0 in January 2018 after 18 months of work, fixing many old issues either directly, or by obsoleting/replacing the features they were referring to. It might work such that i can do what i wanted to do in the first place :-)įirst of all thank you for your report and sorry for the delay. to quote the hhgtth: "this is obviously some new meaning of the word static i wasn't previously aware of." So now that i see the example at i am super confused. (i see the bit about thread safety but actually how that reads is "we'll take away something you would expect to have especially since there's static functions, because our internal workings are too mysterious and haven't been thought out well enough to let static variables exist.) I might be utterly misunderstanding what static means in gdscript but it looks to me more like class-members instead of the c static keyword. (of course on the other hand i agree that objects are little computers and class level variables as well as instance members are all in a sense global from the perspective of the methods, so "global" as a pejorative is true depending on what level of scale one is talking about.) Consult this FAQ entry for available workarounds.I am confused by this thread. If you don't need this, you can add the # attribute to the struct declaration.Īt this point, arguments cannot be passed into the constructor. ![]() With a new() method, you are able to write GodotApi.new() in GDScript. The parameter can be a shared reference &T or a TRef. The base is the base object of the script, and must correspond to the class specified in the # attribute (or Reference if the attribute is absent). The function new() corresponds to _init() in GDScript. For the user, the utility methods new_instance() and emplace() are provided for constructing Instance objects. ![]() Among other information, this includes class name and registry of exported methods and properties. It implements the NativeClass trait, which fills in the glue code required to make the class available in Godot. The # macro enables a Rust type to be usable as a native class in Godot. ![]() which registers methods in the background. Exactly one impl block can have the # annotation, * Unlike 'extends' however, only existing Godot types are permitted, In that case, the 'Reference' class is used as a base. * Like 'extends' in GDScript, this can be omitted. Specify the base class (corresponds to 'extends' statement in GDScript). Tell godot-rust that this struct is exported as a native class Similar to the Hello World example, we can define the GodotApi native class as follows: #! For this chapter, let's assume you want to write a class GodotApi, which exposes a public interface to be invoked from Godot. The argument init refers to the function registering native script classes, which is also defined by you. godot-rust provides the following macros (consult their documentation for further info and customization): #! Somewhere in your code, usually in lib.rs, you need to declare the functions that will be called by the engine when the native library is loaded and unloaded, as well as the registration function for native classes exposed to the engine. To achieve this, every godot-rust application integrated with the engine must expose a public interface, through which Godot can invoke Rust code. This workflow implies that when you want to execute Rust code, you need to first pass control from Godot to it. The engine works as the host application with the entry and exit point, and your Rust code will be loaded at some point after Godot starts and unloaded before it ends. When working with godot-rust, your Rust code sits inside a dynamic library with C ABI ( cdylib), which is loaded at runtime from the Godot engine. Here, we focus on defining custom classes and exposing them to Godot. They are used for Godot's own types (such as nodes) as well as custom ones defined by you. Versioning and supported platformsĬlasses are a fundamental data type of GDNative. ![]()
