Event

  • Code location: /core/event.js

  • The Septopus Engine uses events to decouple the system, significantly reducing the difficulty of understanding the system.

Event Binding​

  • The Septopus Engine uses events and the VBW.event.on(cat, event, fun, location) method to bind events. It supports multiple bindings at the same time.

  • Septopus Engine uses events to organize events in a tree structure. The supported list is as follows:

      {
          "system": ["init","launch","off","restart","update"],
          "datasource": ["request","update","blocked","recover"],
          "sky": ["change"],
          "time": ["change","newyear","newmonth","newday","newhour","newminitue"],
          "weather": ["change","cloud","rain","snow"],
          "block": ["in","out","hold","stop","loaded","cross","unload"],
          "player": ["fall","death","start","hold","rotate"],
          "effects": ["start","end"],
          "rd_three": ["ready","done"],
          "stop": ["on","leave","beside", "under"],
          "trigger": [ "in","out","hold","touch"],
          "box": [],
          "module": ["parsed","failed"]
      }

Event Trigger​

  • The Septopus engine uses events to trigger using the VBW.event.trigger(cat, event, ev, location) method. After triggering, the bound methods are traversed and executed, and ev is returned for its use.

Target Location​

  • The triggering of the event in the Septopus engine needs to be located at the Adjunct. The system uses the following data structure to process it.

      {
          x:2025,             //Block.x
          y:619,              //Block.y
          world:0,            //World index
          index:0,            //Adjunct index
          adjunct:"wall"      //Adjunct name
      }

  • When you don't need to trigger to the adjunct, you can use a string to mark the event method.
