LCCObject::hasCollision

Queries whether the current LCC model contains collision data.

If collision data is available, the collision detection methods (intersectsRayExt, intersectsRayFromOriginExt, intersectsSphere, intersectsCapsule) become usable, enabling features such as digital human collision detection.

Version Requirement

SDK v0.4.1+

Engine Support

Three.js

API

LCCObject::hasCollision(): boolean

Parameters

None

Return Value

boolean — true indicates collision data is available and collision detection methods can be used; false indicates no collision data.

Usage Example

const ret = lccObject.hasCollision();
if (ret) {
    console.log('Collision function available');
} else {
    console.log('Collision function is not available');
}

Notes

• This method must be called after the success callback of LCCRender.load() has been triggered.
• The SDK only loads collision data within the vicinity of the camera position.
