Intro

The below is a breakdown / bird's eye view of how a sparse-array backed ECS like EnTT or Shipyard works.

Please see the thanks and references at the bottom - without their help I would not have been able to share this breakdown with you... everything here is really just notes and rephrasing of what they've written already :)

Also, these notes do not cover archetype systems (like unity) nor adaptations of archetypes (like in Flecs). Though there's a couple comparative footnotes at the end.

Here we go!

Wasmd setup

Basic WASMD Setup

after make install (or on apple silicon: LEDGER_ENABLED=false make install)

our chain-id is going to be localwasmd our gas denomination is going to be configured to uwasm staking denomination is the default ustake

the following sortof mimics the explicit steps in https://github.com/CosmWasm/wasmd/blob/main/contrib/local/setup_wasmd.sh

dakom

use wasm_bindgen::JsValue;
use web_sys::{window, Url};

#[derive(Debug, Clone, PartialEq)]
pub enum Route {
    Home,
    Profile {
        // optional user id
        // None means "me"
        user_id: Option<String>

// EXAMPLE:

// let contract_1 = Contract::new("contract_1", contract_1::msg::InstantiateMsg{});
// let (gas_used, resp) = contract_1.execute(contract_1::msg::ExecuteMsg::Foo{inner_msg_data: "bar"});

// println!("computational gas used: {}", gas);
// println!("execution response: {:?}", resp);
//
// storage actions can also be calculated by estimating as follows:

dakom

import {AccAddress, Coins, Wallet, CreateTxOptions, MsgStoreCode, MsgInstantiateContract, MsgExecuteContract} from "@terra-money/terra.js";
import {TxResult} from '@terra-dev/wallet-types';

// frequency of polling a transaction to see if it's ready 
export const DEFAULT_TRANSACTION_INFO_POLL_WAIT:number = 500; //500ms

// amount of time to wait before giving up on transaction finishing
export const DEFAULT_TRANSACTION_INFO_TIMEOUT:number = 1000 * 60 * 5; // 5 mins

// amount of time to wait after uploading, due to localterra weirdness 

dakom

this will allow connections to local machines local port to be forwarded to remote_ip and remote port

socat tcp-listen:[LOCAL_PORT],reuseaddr,fork tcp:[REMOTE_IP]:[REMOTE_PORT]

dakom

#!/bin/sh
until cargo +nightly run --bin parse
do
        echo "crashed with exit code $?.  Respawning.." >&2
        sleep 1
done

(I asked): what's the reason for async requiring its data to be 'static? I want to say it's because of multithreading, that the async runtime is free to move everything between threads... but that doesn't apply with JS...

Pauan answered:

@dakom nothing to do with multithreading all heap allocated things must be 'static, because they outlive the stack references are always on the stack therefore they cannot outlive the stack so if you put something onto the heap... such as by using Box, or Rc...
