collisionGroup

Number

Inherited from Shape: src/shapes/Shape.js:72

形状所属的碰撞分组(位掩码). 参见 这一教程.

Example:

// Setup bits for each available group
                    var PLAYER = Math.pow(2,0),
                        ENEMY =  Math.pow(2,1),
                        GROUND = Math.pow(2,2)
                    
                    // 为形状设置分组
                    player1Shape.collisionGroup = PLAYER;
                    player2Shape.collisionGroup = PLAYER;
                    enemyShape  .collisionGroup = ENEMY;
                    groundShape .collisionGroup = GROUND;
                    
                    //为形状设置对应的碰撞分组,下例表明玩家(PLAYER) 只会和地面(GROUND)和敌人(ENEMY)碰撞,而不会与其他玩家碰撞
                    // Note that the players can collide with ground and enemies, but not with other players.
                    player1Shape.collisionMask = ENEMY | GROUND;
                    player2Shape.collisionMask = ENEMY | GROUND;
                    enemyShape  .collisionMask = PLAYER | GROUND;
                    groundShape .collisionMask = PLAYER | ENEMY;
                    
// How collision check is done
                    if(shapeA.collisionGroup & shapeB.collisionMask)!=0 && (shapeB.collisionGroup & shapeA.collisionMask)!=0){
                        // The shapes will collide
                    }
                    

collisionMask

Number

Inherited from Shape: src/shapes/Shape.js:109

碰撞掩码,参见 .collisionGroup.

collisionResponse

Boolean

Inherited from Shape: src/shapes/Shape.js:103

当与其他刚体碰撞时是否产生碰撞作用力。需要注意的是,碰撞仍会产生,但会被禁用。即:该刚体会穿过其他刚体,但仍然会触发碰撞等事件。

id

Number

Inherited from Shape: src/shapes/Shape.js:58

形状的唯一标志符

material

Material

Inherited from Shape: src/shapes/Shape.js:116

用于碰撞的材质,如果这被设置为null, 在物理世界中将使用默认材质替代

position

Array

Inherited from Shape: src/shapes/Shape.js:27

基于刚体的位置

sensor

Boolean

Inherited from Shape: src/shapes/Shape.js:130

如果你希望此形状为传感器,则设置为true。传感器不会产生碰撞,但仍会上报碰撞事件。它在你想在不产生碰撞的情况下知道这一形状是否与其他形状重叠的情况下很实用

type

Number
