eZWalker TeslaClass: CollisionDetectionManager
静态碰撞检测管理类
Details
静态碰撞检测管理(开启执行碰撞功能,终止碰撞功能,获取返回结果等)
Examples
typescript
this.collisionDetectionManager = cloud.getCollisionDetectionManager(); 在CreateApp时调用this.collisionDetectionManager = cloud.getCollisionDetectionManager(); 在CreateApp时调用Hierarchy
Callable↳
CollisionDetectionManager
Methods
setCollisionCallback
▸ setCollisionCallback(fn): void
Details
设置碰撞检测进度回调函数
Examples
调用示例：
ts
function changeFinished(re: any) {
console.log(re)
}
cloud.collisionDetectionManager.setCollisionCallback(changeFinished)function changeFinished(re: any) {
console.log(re)
}
cloud.collisionDetectionManager.setCollisionCallback(changeFinished)Parameters
| Name | Type | Description |
|---|---|---|
fn | (CollisionProgressInfo: CollisionProgress) => void | 回调函数，CollisionProgressInfo指碰撞检测进度信息(包含进度百分比信息,只有当进度为100%才能获取结果) |
Returns
void
collisionCheck
▸ collisionCheck(sampleA, sampleB, collisionType, tolerance): Promise<boolean>
Details
开始执行静态碰撞检测。硬碰撞：两对象发生实际相交，表面最小距离小于容差值的相反数（例如10mm的相反数为-10mm）。软碰撞：两对象未发生实际相交，表面最小距离小于容差值。
Examples
调用示例：
ts
await cloud.getCollisionDetectionManager()
const pVt = await cloud.sceneManager.getVTreeManager()
const node = await pVt.getVirtualRoot()
const node1 = await cloud.sceneManager.getNodeByGuid(['b2d29365fa2983b378174110294378c5'])
const node2 = await cloud.sceneManager.getNodeByGuid(['43054e6f96c13bea6d62092b6867135f'])
const pNode1 = await pVt.createVirtualNode('111', emVirtualNodeType.Node_UnCertain, node!, [node1![0]])
const pNode2 = await pVt.createVirtualNode('222', emVirtualNodeType.Node_UnCertain, node!, [node2![0]])
ret = await cloud.collisionDetectionManager.collisionCheck(pNode1!, pNode2!,CollisionType.HardCollide,10)await cloud.getCollisionDetectionManager()
const pVt = await cloud.sceneManager.getVTreeManager()
const node = await pVt.getVirtualRoot()
const node1 = await cloud.sceneManager.getNodeByGuid(['b2d29365fa2983b378174110294378c5'])
const node2 = await cloud.sceneManager.getNodeByGuid(['43054e6f96c13bea6d62092b6867135f'])
const pNode1 = await pVt.createVirtualNode('111', emVirtualNodeType.Node_UnCertain, node!, [node1![0]])
const pNode2 = await pVt.createVirtualNode('222', emVirtualNodeType.Node_UnCertain, node!, [node2![0]])
ret = await cloud.collisionDetectionManager.collisionCheck(pNode1!, pNode2!,CollisionType.HardCollide,10)Parameters
| Name | Type | Description |
|---|---|---|
sampleA | VirtualNode | 待进行碰撞检测的虚拟节点A |
sampleB | VirtualNode | 待进行碰撞检测的虚拟节点B |
collisionType | null | CollisionType | 碰撞类型 硬碰撞:CollisionType.HardCollide; 软碰撞:CollisionType.SoftCollide |
tolerance | null | number | 容差(单位为米)，硬碰撞需要碰撞节点重合的距离的绝对值大于等于容差（距离为负值），软碰撞需要碰撞节点的最小距离小于等于容差（距离为正值） |
Returns
Promise<boolean>
是否成功开启碰撞检测(同一时间只允许开启一个检测)
▸ collisionCheck(sampleA, sampleB): Promise<boolean>
Parameters
| Name | Type |
|---|---|
sampleA | VirtualNode |
sampleB | VirtualNode |
Returns
Promise<boolean>
stopCollisionCheck
▸ stopCollisionCheck(): Promise<any>
Details
终止静态碰撞检测
