LS.Physics Class

Defined in: ../src/physics.js:93
Module: LS

Physics is in charge of all physics testing methods Right now is mostly used for testing collisions with rays agains the colliders in the scene

Constructor

LS.Physics

()

Defined in ../src/physics.js:93

Methods

raycast

(
  • origin
  • direction
  • options
)
Array

Defined in ../src/physics.js:103

Cast a ray that traverses the scene checking for collisions with Colliders

Parameters:

  • origin Vec3

    in world space

  • direction Vec3

    in world space

  • options Object

    ( max_dist maxium distance, layers which layers to check, scene, first_collision )

Returns:

Array:

Array of Collision objects containing all the nodes that collided with the ray or null in the form [SceneNode, Collider, collision point, distance]

raycastRenderInstances

(
  • origin
  • direction
  • options
)
Array

Defined in ../src/physics.js:338

Cast a ray that traverses the scene checking for collisions with RenderInstances instead of colliders Similar to Physics.raycast but using the RenderInstances (if options.triangle_collision it builds Octrees for the RIs whose OOBB collides with the ray)

Parameters:

  • origin Vec3

    in world space

  • direction Vec3

    in world space

  • options Object

    ( triangle_collision: true if you want to test against triangles, max_distance: maxium ray distance, layers, scene, max_distance, first_collision : returns the first collision (which could be not the closest one) )

Returns:

Array:

array containing all the RenderInstances that collided with the ray in the form [SceneNode, RenderInstance, collision point, distance]

testSphere

(
  • origin
  • radius
  • options
)
PhysicsInstance

Defined in ../src/physics.js:205

Test if a sphere collides with any of the colliders in the scene

Parameters:

  • origin Vec3

    in world space

  • radius Radius
  • options Object

    layers, colliders, scene

Returns:

PhysicsInstance:

the first PhysicsObject that collided with, otherwise null
