Configuration
| Prop | Type | Default | Description | | -------------- | -------------- | --------- | ------------------------------------------------- | | cameraOptions | object | {} | configuration object for control's camera options | | characterProps | object | {} | configuration object for character | | characterObj | THREE.Object3D | undefined | three.js object for character model | | animationPaths | object | {} | object for animation clip configuration | | onLoad | function | () => {} | called when animation clips are done loading |
cameraOptions
| Prop | Type | Default | Description | | ------------------- | ------- | ------- | -------------------------------------------------------------------- | | yOffset | float | 1.6 | amount of y added to the camera following the character model | | minDistance | float | 0.6 | maximum zoom in capability of camera | | maxDistance | float | 7 | maximum zoom out capability of camera | | collisionFilterMask | integer | 2 | the cannon.js group given to "world" objects for collision detection | | cameraCollisionOn | boolean | off | if turned on, will use colllisionFilterMask to add collision to the camera (experimental and unoptimized) |
characterProps
| Prop | Type | Default | Description | | ------------------- | ------- | ------- | -------------------------------------------------------------------- | | scale | float | 1 | amount to scale the character model | | radius | float | 0.3 | value used for creating character capsule collider | | velocity | float | 4 | speed at which character moves |
characterObj
you can use any model here compatible with the mixamo rig. For best results, use a model sized to the default mixamo character.
animationPaths
this prop expects an object with key/value pairs pointing to a complete set of animations to use on your character model. Refer to the object below for the full list of animations needed, all of which are available as free animations on mixamo.
