Examples

Code Style

I'm always following GDScript style guide but you may find my examples a little weird when comparing to C++ documentation. For example, let's take the following callback chain:

main()
└── client->Authorize()
    └── client->GetToken()
        └── client->UpdateToken()

Their example chain the calls in a way that I don't like to read:

C++

int main() {
    client->Authorize(args, [client, codeVerifier](auto result, auto code, auto redirectUri) {
        client->GetToken(APPLICATION_ID, code, codeVerifier.Verifier(), redirectUri,
            [client](discordpp::ClientResult result,
            std::string accessToken,
            std::string refreshToken,
            discordpp::AuthorizationTokenType tokenType,
            int32_t expiresIn,
            std::string scope) {
            client->UpdateToken(discordpp::AuthorizationTokenType::Bearer,  accessToken, [client](discordpp::ClientResult result) {
                // Last call.
            });
        });
        }
    });
}

So I prefer to create the functions instead:

GDScript

var client

var code_verifier


func _ready():
    client.authorize(args, _on_authorized)


func _on_authorized(result: DiscordClientResult, code: String, redirect_uri: String) -> void:
    client.get_token(
        APPLICATION_ID,
        code,
        code_verifier.verifier(),
        redirect_uri,
        _on_token_received
    )


func _on_token_received(
        result: DiscordClientResult,
        access_token: String,
        refresh_token: String,
        token_type: DiscordAuthorizationTokenType.Enum,
        expires_in: int,
        scopes: String
) -> void:
    client.update_token(DiscordAuthorizationTokenType.BEARER, access_token, _on_token_updated)


func _on_token_updated(result: DiscordClientResult) -> void:
    pass # Last call.
