  #ConnectTheUnityPhysicsDOTS, #ECS, #Unity.Physics, #Unity3D

  !! WIP -- Still writing this one !! <-PREV | NEXT-> First I need to disable my old code. Annotated my `StickyCollisionSystem` with `[DisableAutoCreation]`. Scrap that -- decided to add this functi... Continue reading
• Post-jam next steps
  June 05, 2019 by Arakade#ConnectTheUnityPhysicsDOTS, #ConnectTheUnityDOTS, ##extragamejam, #extragamejam

  What's next? EntityKiller needs to remove joints. Posted my first question to the giant Unity.Physics discussion thread on this. Some final 'fun' / gameplay? (see below) Aesthetics: Visuals for stic... Continue reading
• Post Jam: An empty EntityQuery in OnCreate() disables your system
  June 04, 2019 by Arakade##extragamejam, #ConnectTheUnityDOTS, #ConnectTheUnityPhysicsDOTS

  OK so interesting result of initialising an `EntityQuery` in a system's `OnCreate()` is that it's considered by ` ShouldRunSystem() `. If the query doesn't result in any contents, the System will not... Continue reading
• Monday night: Joint add or set
  June 04, 2019 by Arakade##extragamejam, #ConnectTheUnityDOTS, #ConnectTheUnityPhysicsDOTS, #extragamejam

  So I need to add or set the `PhysicsJoint` component data depending whether one is already present. However I'm not working with the `EntityManager`, I'm working with an `EntityCommandBuffer` which d... Continue reading

  June 04, 2019 by Arakade##extragamejam, #extragamejam, #ConnectTheUnityDOTS, #ConnectTheUnityPhysicsDOTS

  (TODO: talk about trying to get matrix into the job, `GetComponentDataFromEntity()` didn't work, trying to access via `EntityManager` within the job, pass in the Translation, etc to construct. Nope.)... Continue reading
• Saturday night: Implementing DOTS Unity.Physics OnCollisionEnter() only for certain IComponentData
  June 02, 2019 by Arakade##extragamejam, #extragamejam, #ConnectTheUnityDOTS

  Decided to try creating a "tag" `ComponentType` `StickCause` that indicates a physics entity should stick to something. How to filter query my `CollisionSystem` to only fire my `CollisionJob` for coll... Continue reading
• Saturday afternoon Unity.Physics and DOTS samples strife (after late start)
  June 01, 2019 by Arakade#ConnectTheUnityPhysicsDOTS, #extragamejam, ##extragamejam

  Where I struggle with tiredness and the "preview" nature of Unity.Physics and its samples but emerge victorious and ready to get sticky! -- Super-late (midday) start due to family stuff and a headache... Continue reading

  June 01, 2019 by Arakade##extragamejam, #extragamejam, #ConnectTheUnityPhysicsDOTS

  I notice there are joints in the samples too. Hmm... let's see what it feels like to stick things together :) Shall we do it by things sticking to the player or sticking to each other or maybe shots... Continue reading
• Inception & WebGL build
  May 31, 2019 by Arakade##extragamejam, #extragamejam, #ConnectTheUnityPhysicsDOTS

  Decided to use the Extra Credits Game Jam 2019 to learn Unity DOTS and Unity.Physics (their new physics library). The Jam's theme " Connect " immediately suggested something Katamari Damarcy, World o... Continue reading
