CryptoVoxels Scripting

零、目的：使地块变得可交互

交互方式：

• 单人（默认）
• 多人（地块Owner配置后，通过Grid服务器实现）

一、基础知识

1.1 Feature object

Feature List

Feature Location

• Position
• Scale
• Rotation

1.2 Player object（当前玩家）

关键属性

• player.name => 'captainbenis.eth'
• player.wallet => '0x2D891ED45C4C3EAB978513DF4B92a35Cf131d2e2'
• player.uuid => avatar uuid for this instance of the player (player may have multiple tabs open with seperate avatars)

4.1 围着你转的狗子

1. 代码

setInterval(() => {
	let p = parcel.getPlayers()[0]
	
	if (!p) {
		return
	}
	
	let v1 = feature.position
	let v2 = p.position
	let angle = Math.atan2(v1.z - v2.z, v1.x - v2.x)
	
	feature.rotation.y = Math.PI / -2 - angle
}, 50)

4.2 一直跟着你的狗子

1. 代码

//Makes an object grabbable v1.1 - Fayelure

let Distance_to_player=0.5 // How far the object is relative to the player (negative will be behind)
let up_down_constant= -0.65  // Positive object will go higher, negative will go lower. eg: -0.65 places the object where your hands are, approximately. 0 will place the object right above your eyes.
let refresh_rate = 50       // Number of milliseconds. Please avoid a refresh rate < 30 as it could crash the grid.

let clone = false; // change this to false if you want to not clone the object.

//-------------- Do not touch ---------------------------

function moveObject(object,player){ // calculates new position of object

  let spherePos = object.position;
  let playerRotation = player.rotation;

  let xDelta = Distance_to_player*Math.cos(-playerRotation.y+Math.PI/2 + Math.PI);
  let yDelta = Distance_to_player*Math.tan(playerRotation.x);
  let zDelta = Distance_to_player*Math.sin(-playerRotation.y+Math.PI/2 + Math.PI);

      var positionRell = [
    player.position.x - xDelta,
    player.position.y - yDelta +(up_down_constant),
    player.position.z - zDelta
  ];

return positionRell
}

function setPosition(newobject,e){ // refreshes the positions
    newobject.set({position:moveObject(newobject,e.player)})
  if(!newobject.position || !newobject.rotation){
    parcel.removeFeature(newobject)
  }else{
  setTimeout(()=>{
    setPosition(newobject,e)
  },refresh_rate)
  }
}

feature.on('click',e=>{ // On click, create new object and start refreshing the position
let newobject = feature
if(clone){
newobject = parcel.createFeature('megavox')
newobject.set({scale:[feature.scale.x,feature.scale.y,feature.scale.z]})

newobject.set({url:feature._content.url})
newobject.position=feature.position
newobject.rotation=feature.rotation
}

setPosition(newobject,e)

})
