Update: The refactoring is going well but slower than I like. I added a temporary component refactoringcomponent which serves as a shim between the old system and the new one. It's a mega component that stores _all_ the attributes, which I incrementally reduce as each attribute is refactored out. I started adding some components, like transform which just stores the position of an entity, aicontrol which lets the ai system control an entity, and humanoidcontrol which is basically a human without a control. For debugging purposes the components can print out their contents. For example some of the components in a human entity (id=2) are printed below.

Entity 2
  transform {x: 367.819, y: 319.005}
  refactoringcomponent {
    old_x: 367.708
    old_y: 319.005
    vx: 3.33333
    vy: 1.65674e-008
    on_ground: true
    on_ladder: false
    max_ground_speed: 5
    max_jump_force: 8
    health: 14
    health_max: 14
    recovery_timer_ms: 0
    blood_colour: 4278190335
    is_flammable: true
    ...
  }
  aicontrol {physicsId: 0, init: false, decisionTimer: 0, chaseTimer: 0, chasingMoonman: false, checkGroundTimer: 0, isJumping: false}
  humanoidcontrol {...}
}

Let's all send some cheers out to eigenbom!  Apparently, he's serious about finishing the Moonman this year! Good on ya, mate!

I'm just saying this because it kinda sucks not to have this devlog on the front page every time I come to the forum. But knowing that it's for a greater good makes it bearable.

Hey thanks kleibs. I've been busy doing the refactor, it's all boring stuff, but when I get back to features I'll be posting more again. :D

Update: Refactored many components now, but stilling wrestling with random crashes and annoying things. I also cleaned up some of the system logging stuff, here's the starting log, telling me how much memory I'm allocating for each component. It's currently set low to speed up booting.

Have you considered running a static code analysis tool on your code base?

[eigenbom]

Hey kleibs, yeah I've run msvc's static code analyser, it's pretty interesting. It basically just picked up a few uninitialised variables or complained about potential memory access errors - most of which were covered by checks in my code.

Update: Refactored the physics and sprite components, which were some of the largest. Here's what some of the new code looks like when using the Health component -- which you'll note is similar to the toy system I described a few pages back. Things are coming together, slowly.

Code:

void handleEvent(const EvDamageEntity& ev){
  Entity& e = gCore->entitySystem->lookup(ev.entity);
  if (e.has<Health>()){
    Health& h = e.get<Health>();
    h.health -= ev.amount;
    if (h.health <= 0){
      queueEvent(EvKillEntity(ev.entity));
    }
  }
}

Update: Most of the stuff is refactored now, there's just a couple of remaining old-style attributes that I need to work on. Here's a print out of a new type entity and its components. The line + Transform 2 {...} specifies that Entity 2 has an enabled (+) component called Transform that has id=2 and contents {...}.

Code:

Entity 2
  + Transform 2 {x: 353.23, y: 319.007}
  + RefactoringComponent 2 { sprite_map_id: 472446486, }
  + Physics 2 { type: 1, body: 48947548, landedThisFrame: false, onGround: true, onLadder: false, numFootContacts: 1, leftFootContact.numFlat: 2, rightFootContact.numFlat: 1, numLadderContacts: 0, numLeftEdgeContacts: 2, numRightEdgeContacts: 4, numLeftBlockedContacts: 0, numRightBlockedContacts: 0}
  + Animal 1 { init: true, isWalking: false, direction: 0, decisionTimer: 1.61579, checkGroundTimer: 0.025, isJumping: false, isWhackingRight: false, isAttacking: false, triggerRightArmAttackAnim: false, attackTimer: 0, onGround: true}
  + SpriteDriver 1 { init: true, mode: 1802264951, animating: true, playOnce: false, resetToFirstFrame: false, removeOwnerOnFinishPlaying: false, frame: 0, time: 0.887108, rotation: 0, flipHorizontal: true, flipVertical: false, tint: rgba(255,255,255,255), playbackSpeed: 3.33333, spriteHasFire: false, isProjectile: false, isSpriteOrientable: false, lastSignificantProjectileVelocity: vec2(1,0), isPickupable: false, isAttached: false}
  + Health 2 { health: 6.81482, health_max: 10, blood_colour: 4278190335}
  + Renderable 2 {init: true, layer: MIDDLEGROUND, z: 100, parent: 0, partIndex: 0, children: }
  + Info 1 { description: "a cat"}
  + WorldObject 2 { ... }
  + Flammable 2 { isAlight: false, isAlightForever: false, alightTimer: 0, burnTimer: 0, isFuel: false}
  + Breather 2 { gaspTimer: 0, breath: 5, breathMax: 5, }

Just been flicking through this thread, there's too much I want to say! Looks lush and good fun. I also like the idea of wearable enemy pelts...

[kcbanner]

Thanks for posting about your entity component system! I've just finished a similar refactor in my engine where I built a similar system, and am delighted to see that our systems are very similar. I was mostly inspired by the Dungeon Siege entity system, which I found described on an old wiki which is now down (but I have the pages saved if you'd like), as well as Scott Bilas' talks: http://scottbilas.com/games/dungeon-siege/. Thanks for sharing and keep up the awesome work!

Too much code talk, post more gifs!

Too much code talk, post more gifs!

Too much C++ code talk !
Port Moonman to Javascript, and then we can talk!

[eigenbom]

@oodavid thx mate
@kcbanner Yeh that's a great article, and was also my inspiration when I wrote the first bit of MM code over 2 years ago.

Update: The refactor is done. I've got to tidy up a few things, but thanks for bearing with me with all these technical posts! Here's an image to appease you:

can't we just have more of both?

Hooray!

Also what are those particles?  Is that guy just super smelly?  They look like smelly particles.

Wow. These aesthetics have come a long way. I'm in When & where can you take my money?

Wait, procedural generation, exploration, resource gathering & crafting? Crap This should have been on my radar long ago

Those flame particles are amazing!
