What you are building

Primary path: data/<namespace>/dai_blocks/
Build native/custom blocks with states, luminance, collision/shape, interactions and lifecycle callbacks.

Step-by-step

  1. Define one blockCreate a stable definition under dai_blocks and decide whether it needs native registry behavior or a vanilla carrier.
  2. Author physical behaviorSpecify the properties that affect gameplay: shape, solidity/collision, light, redstone/state behavior and lifecycle hooks.
  3. Add placement acquisitionGive the matching block item or place the block through a trusted server function.
  4. Wire callbacksUse place/break/use/neighbor/lifecycle events to call your gameplay functions.
  5. Add presentationCreate blockstate/model/texture assets only after the collision and interaction behavior works.
  6. Test edge casesPlace against every face, piston/redstone-test it if applicable, break it in survival/adventure and reload the world.

Definition of done

  • The feature still works after save/reload.
  • Server state is authoritative; presentation mirrors it.
  • Invalid input cannot duplicate rewards or bypass costs.
  • Two players can use the system without sharing unintended temporary state.
  • Any optional resource pack can be disabled without breaking datapack logic.

Next integration

Once this feature works alone, connect it to a complete loop instead of adding more isolated content. Use the complete-game tracks to see where it belongs in ACMS, Space Between Blocks, MineTrigger or Hollow Spiral.
